Chinese manufacturers hit the southern Africa market big time
Chinese off-highway equipment manufacturers are growing their presence in southern Africa, with distributor networks expanding and an increasingly wide range of machines and linked technology being made available to quarry and surface-mine customers.
SANY, XCMG and LiuGong are among the major Chinese manufacturers with a strong foothold in the market.
The heavyweight off-highway machine trio have long been competitive on price in the around 10,000 unit, US$4.3bn-a-year southern Africa market. And in recent years, more and more quarrying and surface-mining sector customers are citing high-quality engineering and aftermarket packages, including comprehensive equipment servicing and replacement parts availability, as reasons to look east for their equipment purchases or rentals.
Inside your new issue of ABI, our contributing editor Munesu Shoko travels to the Mpumalanga region of South Africa to see how, in a challenging 24/7-operating environment where downtime is out of the question, familyowned aggregates producer Afrigrit is thriving via a proactive maintenance approach that has seen two of its eight CLG856H LiuGong wheeled loaders clock over 30,000 hours, equating to 4,300 hours a year or 360 hours a month, while maintaining a remarkable 80% availability.
In an insightful three-page Quarry Profile feature, Afrigrit logistics manager Marius Pick tells Shoko that this eye-catching feat is a testament to the durability and reliability of the LiuGong machines and, even more crucially, to the stringent 250-hour service intervals maintained since their acquisition in 2017. Pick notes that every machine is only as good as the service support behind it, with Burgers Equipment & Spares, the sole importing, selling, and marketing agent for LiuGong Machinery in South Africa, having “surpassed our expectations”.
Japan is another Asian country whose
leading off-highway manufacturers have established an impressive footprint in Africa, none more so than Komatsu.
I recently enjoyed a fascinating discussion with Eric Perben, Komatsu Africa’s general manager, who heads up a team covering a 12,000-units-a-year African market covering 40 countries from Angola and the Democratic Republic of Congo north, excluding Egypt and North Sudan, which come under Komatsu’s Middle East business.
Perben, who sold Komatsu machines as general manager of BIA Africa before taking up his Komatsu Africa leadership role in May 2021, told me how Komatsu Africa had more than doubled its product sales in the last two-and-a-half years, with year-on-year double-digit growth forecast for the next three years.
Crucially, as Perben notes, Komatsu’s Japanese headquarters leadership team is fully behind the manufacturer’s big African market development, with Komatsu’s current mid-term management plan setting the goal of the company becoming one of Africa’s biggestselling original equipment manufacturers (OEMs) by 2025.
Perben takes pride in the quality of Komatsu Africa’s customer-servicing capabilities and distributor network, saying: “Massive investment has gone into Komatsu’s global market warehousing site in Belgium, which was recently extended by 20,000m². The warehouse now has €500 million worth of parts and components, with €200 million of the inventory dedicated to mining customers. There is 95%-96% parts and components availability. Since last year, we have also been able to keep machine stock at a port in the Netherlands to shorten lead times. That and the warehouse extension were key parts of a growth plan I submitted to Komatsu Japanese senior management in 2021.”

LeadIT & GCCA launch Green Cement Technology Tracker
The Leadership Group for Industry Transition (LeadIT) and the Global Cement and Concrete Association (GCCA) have launched a new tracker to help policymakers, industry experts, academics and the public monitor worldwide decarbonisation efforts in the cement industry. The Green Cement Technology Tracker was unveiled at an international intergovernmental meeting focused on clean energy, which is taking place in India (CEM14-M18).
Cement and concrete are vital to the built environment, used for homes, infrastructure, and to provide things like clean running water. But the sector also accounts for 7% of global CO2 emissions. With the launch of the
plan
Launching the Green Cement Technology Tracker is the next step along the industry’s roadmap.
Per Andersson, head of the secretariat – LeadIT, said: “To empower the industry and policymakers committed to emission reductions, our goal is to provide comprehensive tracking of public announcements of investments in low-carbon cement technologies.”
The Green Cement Technology Tracker currently includes Carbon Capture and Storage (CCS) and Carbon Capture Utilisation and Storage (CCUS), accounting for 36% of planned reduction levers in
the GCCA 2050 Roadmap for Net Zero Carbon Concrete that leading manufacturers have committed to. Future steps to enhance the tracker include expanding its scope to cover more technologies that reduce emissions from cement manufacturing.
Thomas Guillot, chief executive of the GCCA, said: “Unleashing technology such as CCUS is key to achieving our net-zero mission in our sector. Carbon-capture pilots, projects and announcements are picking up pace across the world. This technology works, and our next goal is to scale up, working with stakeholders such as governments and the investment community to help transform the industry worldwide.”
AUCBM partners on CarbonZero conference
The Arab Union for Cement and Building Materials (AUCBM) has been announced as an official partner for the upcoming CarbonZero Global Conference and Exhibition.
The conference - Alternative Fuels and Raw Materials for Cement and Construction - takes place on October 26 and 27 in Lyon, France.
AUCBM is an inter-Arab international organisation affiliated with the Council of Arab Economic Unity, and it was founded in 1977. Its headquarters are in Damascus, Syria. In 2016, AUCBM established a regional office in Amman, Jordan.
The Union aims principally to develop and support technical, industrial and commercial relations; coordinating industrial activities amongst its members in the field of cement and building materials; and participating in suggesting general grounds for developing these industries in Arab
countries to achieve technical and economic integration among Arab countries through practising its tasks and responsibilities.
The AUCBM members from cement and building materials companies, establishments and research centres represent 115 institutions from 18 Arab countries.

Komatsu eyes greater African gains
Komatsu’s mining, quarrying and construction equipment trading has grown impressively in recent years, with the Japanese off-highway machine giant’s senior management team seeing the continent as a key part of the company’s future. Guy Woodford spoke to Komatsu Africa’s general manager Eric Perben to learn more about Komatsu’s African present and future
Komatsu has more than doubled its African product sales in the last two-and-a-half years, with year-on-year double-digit growth forecast for the next three years.
The world’s second-biggest off-highway equipment manufacturer’s 2022-published mid-term management plan includes becoming one of Africa’s biggest-selling original equipment manufacturers (OEM) by 2025, with ongoing continent-based employee recruitment- and distributionpartnership widening and strengthening seen as critical to achieving that goal.
In May 2021, Eric Perben, a French national, became general manager of Komatsu’s new African business, a business covering 40 countries from Angola to the Democratic Republic of the Congo (DRC) north, excluding Egypt and North Sudan, which come under Komatsu’s Middle East business. Komatsu has a separate major southern Africa business covering nine countries: South Africa, Mozambique, Botswana, Namibia, Zambia, Zimbabwe, Malawi, Madagascar, and Mauritius.
Perben’s 12,000-product-sales-a-year African market was one he knew very well, having spent eight years until joining Komatsu selling the manufacturer’s machines as general manager of BIA Africa, a highly successful off-highway machine distributor. Before joining BIA Africa, Perben spent 17 years at Volvo Group, working in varied managerial roles in Belgium, France, and Singapore.

“Over all my years in this industry, I’ve learned that the higher up you go, the more important it is to be in the field listening to customers and having a sense of what they need. You also need an enthusiastic and passionate team working with you and a workplace full of energy and fun,” he explains, adding, “In my eight years as general manager of BIA Africa, I developed an entrepreneurial spirit and learned how to manage risk. We grew the business substantially after significantly restructuring the company into different trading divisions. The company traded for Komatsu in five or six countries when I arrived and in another six by the time I left.”
Since establishing Komastu Africa, Perben has overseen an intense recruitment drive leading to employee numbers rising from three to 25. “We have two central offices, in Dakar, Senegal, and Nairobi, Kenya. They contain technical and marketing people who travel and support our distributors. To speak the same language as the customer, you need to have credibility. Credibility comes from spending a lot of time in the field – so I like to surround our team with experts.
“There are simple things you can do to generate big gains. In mining, quarrying and construction, an operator with bad habits means you lose 30% in fuel consumption. So, we have several Komatsu schools where our distributors can give technical training to our customers’ machine operators while offering customers expert business-operation advice.
“Additionally, Komatsu purchased two big machine-training simulator companies, Immersive Technologies and Oryx Simulations. Our new mining trucks have KomVision [Human Detection & Collision Mitigation System], so you can film truck operators at work and automatically detect and upload to the simulator footage of their faults over a 12-hour shift. The simulator will generate a training guide telling the operator what to do differently to improve their safety and fuel consumption.”
Perben stresses the quality of Komatsu Africa’s customer machine-servicing capabilities and distributor network, both strengthened under his leadership and reinforced by strong support from the company’s Japan-based CEO and executive management team. “Massive investment has gone into Komatsu’s global market
warehousing site in Belgium, which was recently extended by 20,000m². The warehouse now has €500 million worth of parts and components, with €200 million of the inventory dedicated to mining customers. There is 95%-96% parts and components availability. Since last year, we have also been able to keep machine stock at a port in the Netherlands to shorten lead times. That and the warehouse extension were key parts of a growth plan I submitted to Komatsu Japanese senior management in 2021.
“These improvements have played a massive part in significantly increasing our African sales. We have also created a financing arm to help finance machine purchases by our African customers. It started three to four years ago, but we started actively marketing it in 2021. It’s 100% Komatsu financing. It makes a difference; we have real skin in the game!”
Perben says mining is the core business in Africa, with many countries developing their industry, keen to get to vast untapped minerals. He continues: “You have three types of customers: owner miners, contractor miners, and Chinese-run mines. The owner miners will take the biggest and most adaptive machinery. Contractor miners have to have a versatile fleet. They don’t have long-term-enough contracts and can’t commit to electric-powered machines. The Chinese miners tend to use a lot of smaller machines, which can create greater supply chain and human resources issues than in big mining
nations like Australia and the United States.
“Surface and underground mining machines in our African market generally work with hard rock, whereas mines in southern African countries process a lot of softer rock. We are currently more involved with surface mining in Africa, but increasingly, surface mines are depleted, and underground mining is becoming more popular. We have varied customers –from those involved in small-scale gold mining to those running large-scale copper operations. These customers need dump trucks, for example, ranging from a 40-ton machine to a 400-ton electric model.
“Some mining markets that are supposed to be quite big have been depressed for quite a long time. Algeria, for example, should be a very big market. Its [off-highway machine] importers’ market has reopened after three years, creating new business opportunities. Elsewhere, we trade in three countries without elected governments: Mali, Guinea, and

Burkina Faso. Mining is a large part of African countries’ GDP (Gross Domestic Product), and governments are getting royalties, so mines are largely unaffected.
“Other markets are more active and buoyant, like the DRC and Guinea, the latter where the largest iron ore mine in the world will open in Simandou. Guinea is also one of the largest bauxite producers globally. China wants to diversify its supply from Australia and the Americas, so it is diversifying and investing massively in Guinea’s bauxite mines. The same thing is happening in the DR with cobalt and copper.”
Perben says there is also a lot of mining industry development in Africa linked to the energy transition, with new metals mined, including lithium, graphite, and cobalt.
Although Komastu is in the African quarrying business, with quarries providing materials for road construction and other infrastructure works, Perben emphasises that it’s unlike Europe, where, he says, there is a very well-developed sector and some “massive” quarries.
So, where does Perben think the biggest growth for Komatsu Africa will come from in the next few years? “If you are talking about construction, the Ivory Coast and Kenya are undertaking big infrastructure development. To an extent, Ghana offers good sales opportunities, especially if it gets its affairs together with support from the IMF (International Monetary Fund). We are very focused on our African construction customer business and are making some very good inroads, with excellent support from Japan and our distributors.
“The DRC, Guinea and the Ivory Coast will be the biggest mining growth markets. Tanzania is coming back with a more stable government. Ethiopia, Eritrea and Mauritania are other countries looking to develop their mining business, presenting interesting commercial possibilities. Angola is also a good market for diamonds.”
Asked which Komatsu machines are proving most popular with African mining customers, Perben responds: “We have the reference machine in the 100-ton rigid dump truck class, the HD785. It is unmatched in terms of performance. The customers look at that as it has a massive presence in the market. We have HD785 customers whose truck has done more than 80,000 hours! That’s a lot when you consider it is working on your site for 5,000-7,000 hours a year when you are working 24/7. Those machines still have a mechanical availability above 85%.
“We also have one of the best 200-ton class excavators [PC2000] to load the HD785. They are an extremely good combination due to their lower lifecycle cost. For bigger mines, we have the highly productive HD1500 truck working, for example, in manganese mines. We don’t have much competition, other than Caterpillar, in that sized market. We also have autonomous mining trucks and have had them for more than 20 years, working for millions of hours. We also have 200 to 400-ton electric-drive trucks. The high power
consumption is when the truck comes out of the pit, so we have several sites with a ‘trolley assist’ that reduces fuel consumption and carbon emissions.
“We have shovels starting from 120 tons to an 800-ton hydraulic shovel. We also have an electric rope shovel – a small 10.7m³, 18 metric tonnes per bucket one, all the way to a 70m³, 122 metric tonnes per bucket. We have the WE2350, the largest wheeled loader in the world, which gives you up to 72 tonnes per bucket. It can load up to 360-ton trucks. Nobody in the African mining machine market can match this range.”
Giving examples of how Komatsu’s machines have helped African mining customers, Perben says that there are customers in Senegal and Mali whose 100-ton trucks were involved in a site study by a Komatsu application engineer, which showed that with a side extension, the trucks could achieve a 15% additional payload while also
dramatically reducing their cost per ton and total lifecycle cost.
He adds: “These productivity gains and cost savings are important as mining operations are judged on two things: one is output and meeting their promise to the market, and the second is their cost sustainability. Of course, fleet machinery is a big part of the latter, with processing plants another.
“We work hard to support our distributor to deliver continuous improvement for customers’ operations. For example, we do drone surveying and reprofiling of construction sites to ensure they are more efficient in their excavation and do things right the first time; that lowers customers’ cost per ton and operating costs. You get the deal [machine order] if you can prove that you can reduce a customer’s cost per ton.”
Perben says Komatsu plans to make available for African customers the same machine and fatigue-control-inclusive

intelligent machines already offered in other international markets. “These machines position themselves with GPS and allow customers 3D joystick control. They can also talk to each other to align their work to improve production efficiencies through, for example, better bucket positioning. Just because we are working in Africa doesn’t mean that the machines and technology offered to customers should be sub-standard. The only difference is that we have machines that are fit for purpose to work in Africa, so we don’t have Tier 4 or 5 emission machines, only Tier 2 or 3, depending on the fuel quality.”
ESG (Environmental, Social & Corporate Governance) and digitalisation are critical issues for African mining, quarrying and construction customers, stresses Perben. “Decarbonisation is a sub-set of ESG and a big challenge for customers. We are big on reducing their Scope 1 and 2 emissions and are very supportive of reducing customers’ Scope 3 emissions, which comprise around 90% of carbon emissions and are linked to machine use. ESG used to be a nice thing to have at the back of a report; now, you have to measure it and prove that you are making a difference to the environment and your local community to continue to get work. It is good for business and the planet.”
Perben notes how EARTHBRAIN, a company created from a joint venture involving Komatsu, Sony Semiconductor Solutions Corporation and Nomura Research Institute, supports digital transformation in the global construction industry for dramatically improved safety, productivity and environmental performance.
He also highlights how Komatsu is working with some mining customers to rapidly innovate to support carbon-reduction targets. Through the Komatsu Greenhouse Gas (GHG) Alliance, Rio Tinto, BHP, Codelco, and Boliden are working directly with Komatsu to actively collaborate on product planning, development, testing and deployment of the next generation of zero-emission mining equipment and infrastructure. The alliance’s initial target is advancing Komatsu’s power-

agnostic truck concept for a haulage vehicle that can run on various power sources, including diesel-electric, electric, trolley (wired), battery power and even hydrogen fuel cells.
As a company, Komatsu is committed to minimising environmental impact through its business, targeting a 50% reduction in CO2 emissions from using its products and production of its equipment by 2030 (compared to 2010 levels) and a challenging target of achieving carbon neutrality by 2050.
“We have a long history of doing good things for the environment,” continues Perben. “For example, we were the first manufacturer to offer widespread remanufacturing of factory components. When doing this, you are giving the core of the component back, meaning you have a component of the same level of quality
as the original. We are so confident of this remanufactured quality that we offer a two-year warranty or 10,000 hours of service, whichever comes first. It shows the commitment of Komatsu to quality and the environment.”
While based at Komatsu Europe International’s headquarters in Vilvoorde, Belgium, Perben makes regular week-long trips to Africa, spending time in several countries on each visit. He also travels to Japan for face-to-face meetings with senior company management. “I’ve been to seven African countries in the past four months,” he says. “I’ve increased my time there, even though our staff numbers have grown. We have a huge diversity in the team, which I’m passionate about. They are doing great things. So great that I think we can reach our 2026 sales and income ambitions by the end of this year, so we are redefining our strategy to be even more ambitious.”
Asked whether Komatsu will look to establish manufacturing or parts warehouse facilities in Africa, Perben responds: “Until there is an economic zone like in the EU, it is very complicated to have parts warehousing in Africa. It is the same with manufacturing, as there is no critical mass, no single country in our African market that justifies a production facility. Also, if you want to transfer a machine between neighbouring African countries, it is sometimes quicker for the sending country to send it via a European port like Antwerp or Rotterdam. You can fit Russia between our two offices – Kenya in East Africa and Senegal in West Africa. That gives you an idea of the size and logistics of our market.”
Married for many years to a Dutch wife and the proud father of two daughters and a son, all in their 20s, Perben is a fully qualified sailing instructor, with a lifelong passion for the sport. He has many fond memories of outings with students on his boat, Optimist, off the Brittany coast in northern France.
Given his demanding Komatsu Africa leadership role, does he still get a chance to sail? “I keep two boats in the French Mountains near Gap [in the Provence-AlpesCôte d’Azur region of Southeastern France], where there is a big artificial lake and a lot of wind, which is great for sailing. I used to do a regatta, but now I only tend to sail in the summer. My work with Komatsu does not leave much time for anything else.” AB

Opportunity knocks in Indonesia
The building of Indonesia’s new capital city and other big infrastructure projects offers exciting commercial opportunities for construction materials suppliers and off-highway equipment manufacturers. Guy Woodford reports
On an island on the edge of the Pacific Ocean, 2000km northeast of Java, a trio of Rokbak RA40 haulers are operating across a 45,065-hectare mining site.
At this remote location in North Maluku, Indonesia, the Rokbak articulated haulers operate up and down steep inclines, through mud, dirt, grit and gravel, for almost 24 hours a day, in 30°C heat and at the mercy of the Southeast Asian elements.
Required to move around 450 tonnes of biomass and quarry materials in a single day, each RA40 will record approximately 6,000 operating hours per year. The haulers are tasked with removing overburden and providing mine development support for the acquisition of high-demand nickel, the harder-than-iron metal used in some form in practically every aspect of day-to-day life. Every full-capacity payload sees each RA40 transport overburden two kilometres to a project access road and biomass dump for disposal.
Nickel is found everywhere. It’s in coins, turbine blades, stainless steel, kitchenware, mobile phones, laptop computers, and television sets. The fifth-most common element on the planet, nickel sulphides develop in environments by spreading tectonic plates in the Earth’s crust and core. Corrosive-resistant, strong at high and low temperatures, durable and able to be utilised
in many ways, nickel’s MO could be strapped to the side of a Rokbak.
PT Hillcon is one of Indonesia's most significant names in the construction, mining, property and heavy-equipment industries. Since its beginnings in 1995, the company has completed hundreds of projects across the archipelago in coal and nickel operations. Its current occupation in the world-class nickel deposit of Weda Bay, in North Maluku, is a five-year process that began in September 2021. It will last until Q4 2026, when PT Hillcon will have produced an estimated four million tonnes of nickel.
PT Hillcon’s three Rokbak haulers were acquired through Rokbak dealer PT Uniquip, an equipment supplier based in Jakarta. With Hillcon’s nearly three decades of experience in the industry and 100 ADTs in its fleet already, PT Uniquip helped highlight why Rokbak haulers would be well suited to PT Hillcon’s demanding work.
PT Hillcon is one of many Indonesian construction company success stories. Like its domestic competitors, it is based in the world’s fourth-most populous country, home to around 270 million people. The good news for PT Hillcon and its construction firm rivals is that Indonesia urgently needs new public infrastructure, including modern housing and commercial buildings. The country is also the largest county in ASEAN (Association of Southeast Asian Nations), with a land area of
1.919 million km², a sea area of 3.16 million km² (exclusive economic zone) and huge mineral resources.
Asian Insiders, a network of in-country business experts providing the inside track to entering and succeeding in business in Asia, quotes a Bandung Institute of Technology estimation that Indonesian cement consumption is set to rise by a third to 84 million tonnes per year (from around 65 million tonnes/year) following the July 2022 start of construction of the country’s new capital city, Nusantara.
Situated on the east coast of the island of Borneo, Nusantara is scheduled to be inaugurated on 17 August 2024, coinciding with Indonesian Independence Day. Nusantara will replace Jakarta as the national capital, a position the latter city has held since the country's independence in 1945.
Nusantara is expected to encompass an area of 2,560km², surrounded by hilly landscapes, a forest, and a natural bay. The city’s 'Government Central Area Zone' will comprise government offices, schools, and hospitals.
Industry analysts believe the Asia-Pacific region, including Indonesia, Malaysia, Vietnam, Thailand, the Philippines, and other countries, will have the fastest demand for sand- and stone-aggregate growth, with the market demand reaching 51.7bn tonnes.
In the third quarter of 2022, Statista,

a leading business market and consumer data provider, reports that around 46.43 million tonnes of cement were used in Indonesia. Consumption of building materials, particularly cement, is driven by the country’s president, Joko Widodo, and his administration’s programme to improve basic national infrastructure, such as roads, airports, and seaports. The COVID-19 crisis has, however, put a stop to some of Indonesia's infrastructure-building initiatives, thus reducing domestic cement consumption. The same source also reports that in 2021 the total volume of sand produced in Indonesia amounted to approximately 67.41 million m³. In comparison, just over 373 million m³ of sand was produced in Indonesia in 2015.
In recent decades, Statista notes that Indonesia’s infrastructure development has focused on Java Island, its most populous island, and its current capital city, Jakarta. In 2021, the value of total construction completed in Jakarta was over forty times more than in Bali and thirty times more than in Papua, showing a huge infrastructure gap. Statista says Indonesia’s president, Joko Widodo, has significantly increased the country’s infrastructure budget since 2014 to reduce development inequality across the archipelago. One of the ongoing infrastructure projects of the current Indonesian government is the construction of 2,650 kilometres of toll roads, scheduled for completion in 2024.
Until April 2022, Indonesia had successfully built 1,900 kilometres of toll roads- far more than the total amount constructed in the last 40 years which was only 780 kilometres. Following the government’s expansive infrastructure agenda, Statista states that Indonesia's cement producers, such as Indocement and PT Semen Indonesia, have boosted their annual production in the past few years. In 2019, Indonesia’s largest cement producer, state-owned Semen Indonesia, increased its annual cement production capacity by around 40%. As a result, Indonesia ranked as the sixth-largest cement-producing nation in the world in 2021.
In 1991, PT Semen Indonesia, commonly known as Semen Indonesia Group (SIG), was the first state-owned enterprise that went public on the Indonesia stock exchange.
The company maintains an annual production capacity of 51 million tonnes, shipped to customers across Indonesia, Sri Lanka, United Arab Emirates, Yemen, Philippines, China, Australia, India, Bangladesh, Africa, Timor-Leste and other countries.
The company has cement plants in Lhoknga in Aceh, Indarung in West Sumatra, Narogong in West Java, Rembang and Cilacap in Central Java, Gresik and Tuban in East Java, Pangkep in South Sulawesi and also in Vietnam. It represents about 53% of Indonesia’s domestic cement sales.

defeated coronavirus pandemic. The company focuses on developing innovations to answer the challenges in building materials and provide solutions to all stakeholders.
Speaking in November last year, SIG director of finance and risk management, Andriano Hosny Panangian, said that amid hypercompetitive market conditions, the company continues to create opportunities by developing diversified products and services to strengthen its position as a sustainable building material solutions provider.
“SIG is a leading building material
solutions company in Indonesia. In addition to controlling the largest domestic cement market share, SIG now has various cement derivative products with a complete range of specifications and support service solutions to meet building conditions requirements according to customer needs wherever they are.”
SIG has five strong cement brands and is the market leader in its respective regions, including Semen Gresik, Semen Padang, Semen Tonasa, Dynamix and Semen Andalas. Furthermore, SIG has integrated cement factories in eight locations, packaging
factories in 26 locations, six cement mills and seven ports. Meanwhile, the distribution channel is strengthened by 306 distributors in Indonesia and Vietnam (TLCC) and 70,000 retail stores in Indonesia.
Panangian added: “SIG offers multipurpose bagged cement products for special applications that are more economical, as well as various types of bulk cement according to the characteristics of each type of project so that it is more efficient and effective. Marketing of SIG products is getting stronger with the presence of three digital platforms, namely SobatBangun, AccessToko and SIG online store that make it easier for customers to get services in terms of development.”
SIG also features concrete solutions, such as SpeedCrete, for high-performance, early-strength road repairs that dry in hours. Then there is ThruCrete, a highly absorbent concrete product to minimise waterlogging. SIG has also launched the first HE-type hydraulic cement product innovation in Indonesia, which has passed the test at the Product Certification Institute (LSPro) of the

SIG presents solutions that meet stakeholder expectations and become a driving force in the growth of the
building material industry that pays attention to sustainability,” explained Panangian.
Regarding the main opportunities for Caterpillar's business in Indonesia’s aggregates and quarrying market, Rahul Srivastava, Industry Solutions manager - Quarry & Aggregates (Asia-Pacific), Caterpillar, says: “During the last decade or so, the Indonesian construction industry has been growing supported by many government initiatives that have driven demand for the quarry & aggregates industry. Caterpillar and its dealer PT Trakindo Utama
offer a wide range of products and services to support their customers, from machine sales to parts, on-board and off-board technology, equipment rental and financing.
“In recent years, quarry operators upgraded their fleet with Cat Next Gen machines for more efficiency, productivity and advanced technologies. To assist with maximising machine life, Caterpillar and PT Trakindo Utama provide solutions that support a lower carbon footprint, such as Cat Reman and Cat Certified Rebuild programmes which can deliver considerable cost savings
GLOBALDATA FORECASTS INDONESIAN MARKET GROWTH
The Indonesian construction market size was $243.2 billion in 2022, according to GlobalData, a leading business market intelligence consultancy. The market is projected to achieve an AAGR (average annual growth rate) of more than 5% from 2024 to 2027. The industry’s output in 2023 will be supported by the government’s focus on infrastructure development.
GlobalData states that the key sectors in the Indonesian construction market are;
• Commercial construction
• Industrial construction
• Infrastructure construction
• Energy and utilities construction
• Institutional construction
• Residential construction
The commercial construction sector, including leisure and hospitality buildings, office buildings, outdoor leisure facilities, and retail buildings, is expected to remain weak in 2023, owing to rising inflation and the relative weakness of the tourism sector.
However, GlobalData expects it to record an average annual growth rate of more than 5% from 2024 to 2027, supported by an anticipated improvement in construction demand in the leisure and hospitality sector, coupled with investment in office, retail, and data centre projects.
Industrial construction project types analysed by GlobalData include chemical and pharmaceutical plants, manufacturing plants, metal and material production and processing plants, and waste-processing plants.
“The industrial construction sector is expected to expand in 2023 before registering an annual average growth of more than 4% from 2024 to 2027, supported by an increase in manufacturing production and investment in the mining and automotive manufacturing sectors,” says the business market intelligence firm.
Indonesia’s infrastructure construction sector, including rail and road projects alongside other infrastructure works, is tipped for growth by GlobalData due to
significant government investment in transport projects to improve regional connectivity.
GlobalData expects Indonesia’s energy and utilities sector to grow in 2023 and record an annual average growth of more than 5% from 2024 to 2027, supported by investment in power, oil and gas, and telecommunication projects.
Public investment in Indonesian health and education projects will, says GlobalData, support growth in Indonesia’s institutional construction sector, coupled with the government’s focus on improving the country’s healthcare infrastructure to lower the number of Indonesians seeking medical services abroad.
Growth in Indonesia’s residential construction sector, including single- and multi-family housing, will, GlobalData predicts, be affected this year by rising borrowing costs, tighter lending requirements and slowing housing sales.
However, the government’s plan to construct five million housing units by 2027 will support the
sector’s recovery from 2024, the same source forecasts.
In an eye-catching construction materials sustainability development, it has been reported that Indocement Tunggal Prakarsa has engaged Japan-based environmental consultancy Amita Holdings to support a two-year feasibility study to investigate ways to make its cement production carbon neutral.
The study will reportedly commence with trials of industrial waste as alternative raw materials and municipal solid waste as refusederived fuel.
Amita Holdings says it is building a recycling-based society in Indonesia in partnership with Indocement Tunggal Prakarsa.
Amita Holdings supported the establishment of the communityled Meguru waste-sorting facility in Central Java. Two of Indocement Tunggal Prakarsa’s cement plants - the 18-million-tonnes-a-year Citeureup cement plant and the 4.1mn-tonnes-a-year Paliman cement plant – are in neighbouring West Java.
and help lower operating costs overall.
Srivastava says PT Trakindo Utama offers a preventive maintenance programme through customer value agreements (CVA) ownership plans and maintenance and repair contracts (MARC) which guarantee maintenance. “For small to mid-size quarries, CVAs are available with a fuel guarantee, preventive maintenance parts kits, equipment protection plans, connectivity through VisionLink, and equipment financing,” he explains.
Asked about the levels of demand for aggregates in Indonesia, and which types are in most demand, Srivastava responds: “After a subdued demand during the COVID period, aggregates demand bounced back in 2022, growing at around 5% although starting back from a low base. It is anticipated the momentum will be maintained during 2023 and 2024 to reach or exceed the pre-COVID level. The increase
in demand is supported by the acceleration of many projects which were either pending or progressing at a slower pace during the COVID restrictions.
“Sand and crushed stone (Andesite, basalt) are two high-demand construction materials. Sand is a key raw material for construction and constitutes the lion’s share of the total aggregate demand.”
Srivastava notes that some environmental and bio-diversity degradation restrictions are making sand a constrained supply. Indonesia has good reserves of andesite, primarily used for rail ballast and road construction. He says the focus on dam and rail-network construction mainly drives the demand for those two construction raw materials and the regular demand for housing construction.
“The demand for limestone used in cement production will also grow, albeit at a somewhat smaller pace,” he concludes. AB

NEW HD HYUNDAI INFRACORE BEGINNINGS IN INDONESIA
HD Hyundai Infracore CEOs Young-cheul Cho and Seunghyun Oh have opened a new business entity (Hyundai Infracore Asia - HDIA) and parts distribution centre (PDC) in Indonesia to expand growth and increase presence in the Asian market with its new construction equipment brand, DEVELON.
An opening ceremony for HDIA and the PDC in Jakarta, Indonesia, in June 2023 marked the start of their operations.
The company also hosted a memorandum of understanding (MOU) ceremony with KB Capital and KB Bukopin on the same day, looking to provide more financial products for purchasing DEVELON construction equipment.
Through this agreement, customers can use instalment
finance products with low-interest rates.
KB Bukopin president Woo-yeol Lee, KB Financial Group chief of Small and Medium Enterprise Sung-ki Kwon, KB Capital CEO Soo-nam Hwang, and managing director In-hwan Kim, along with HDI global CEO and president Young-cheul Cho and HDIA CEO Heewoong Shin, attended the opening ceremony. Other stakeholders and regional dealers also attended to celebrate the occasion.
financial products that meet the needs of local customers through partnerships with related services.
This opening ceremony provides an opportunity for HDI to widen its sales network and distribution supply in the region, including Indonesia, which has an active market for mid-tolarge-sized mining equipment, and to expand the company's business by creating different
The newly opened PDC is 2304m2 in size and is located in Marunda, in the northern part of Jakarta. It will act as a distribution hub to secure and swiftly supply parts for excavators, wheeled loaders and other machines. With the locational advantage of the PDC, it will be able to deliver parts on time within a country composed of many islands and maximise supply chain efficiency to the neighbouring countries.
HDI operates nine PDCs in its key sales regions, including the USA, UK, Germany, China, United Arab Emirates and Singapore, and is expanding its global coverage for parts distribution.
A representative of HDI said: "Indonesia is a strategically
important country as it is abundant with resources and has geological advantages being located near the Indian and Pacific Oceans," and added: "We will work on providing better services for our dealers and customers by optimising inventory management and parts delivery, and reinforce DEVELON equipment sales in the Asian market."
Last year, HDI achieved revenue of KRW 102 billion (around US$78.25 million) in Indonesia, the highest since entering the Indonesian market. The company also plans to attend Mining Indonesia, Asia's largest international mining equipment exhibition held in Jakarta from 13th to 16th September 2023, to present DEVELON equipment to customers in the region.

The LiuGong CLG856H wheeled loader is a 17-tonne (t) machine with a 5-t lifting capacity and comes standard with a 3m³ bucket
WINNING THE DAY
In a challenging 24/7 operating environment where downtime is out of the question, Afrigrit, a South African-based, family-owned aggregates producer, places value on not only uptime but also the longevity of its equipment. Through a proactive maintenance strategy, two of its eight LiuGong wheeled loaders have clocked over 30,000 hours and counting, while maintaining a remarkable 80% availability. Munesu Shoko reports
By maintaining high uptime and longevity, a fleet of LiuGong CLG856H wheeled loaders is winning the day for a Mpumalanga, South Africa-based aggregates producer. Established in 1996, Afrigrit initially specialised in producing sandblasting sand from slag, a by-product of the steel industry. The slag is sourced from Ferrometals, one of the largest individual ferrochrome plants in the world, which produces charge chrome for steel markets.
Over the years, the company has expanded its scope, including the recovery of chrome from slag and eventually production of aggregates for various industries, such as road construction, brick manufacturers and concrete producers, among others.
Metallurgical oxide slag has stone-like properties; thus, its major applications are in civil engineering. Due to the high cost of natural stone and the rising emphasis on sustainable construction, the construction industry in this area is using these aggregates as a viable alternative.
To execute its mandate, Afrigrit has erected a processing plant at the Ferrometals dump to process the slag. Part of the
plant recovers the rich material, which is transported to Afrigrit’s premises to produce sandblasting sand. The other part of the plant recovers chrome for Ferrometals and also produces varied sizes of aggregates for the local market.
Marius Pick, logistics manager at Afrigrit, says maintaining optimal equipment availability is key to ensuring continuity in achieving production targets. Therefore, reliable and consistently available equipment is non-negotiable. This is exactly what a fleet of LiuGong wheeled loaders, supplied and supported by Burgers Equipment & Spares, offers at this 24/7 operation.
Afrigrit bought its first LiuGong wheeled loader in 2008 and never looked back. The company has standardised its loading fleet with the LiuGong CLG856H model, with eight currently running in its fleet. The decision, says Pick, has paid dividends, with these machines providing availability of about 80%, working around the clock.
“We run a 24/7 operation throughout the year, even during the festive period in December. Uptime is especially important for us, and the decision to standardise our fleet with LiuGong wheeled loaders has paid dividends. In addition to 80% availability,
“We run a 24/7 operation throughout the year, even during the festive period in December”

capital and running costs are competitive,” says Pick.
Of note is that two of the current eight loaders have already clocked over 30,000 hours, translating into about 4,300 hours a year or 360 hours a month. This feat speaks directly to the durability and reliability of the machines and, more importantly, to the stringent 250-hour service intervals maintained since their acquisition in 2017. The two machines are expected to continue operating reliably well into the future.
“Being proactive in our heavy equipment maintenance has helped prevent expensive downtime and to extend equipment life. Our machines are serviced by the dealer, Burgers Equipment & Spares, at OEM-recommended maintenance intervals of 250 hours. This means that each machine is serviced at least once a month,” says Pick. “In addition to routine maintenance, the machines are subjected to a 2,000-hour major service.”
The 250-hour routine maintenance also allows Burgers’ technicians to spot potential problems before they escalate into major failures. Corrective actions are taken immediately to ensure the reliability and performance of machines.
While the stringent service strategy keeps machines in great working shape, Pick points out that this is achievable only when parts availability and dealer support are non-issues. This is where Burgers Equipment & Spares has excelled, even going the extra mile to meet Afrigrit’s needs.
“Parts availability and good response times from Burgers Equipment & Spares are key to the success of our operations. Burgers is very much on top of its game. We have never had issues regarding spares availability since we have dealt with them,” he says. To further ensure maximum equipment uptime, Afrigrit also keeps critical spares on site, such as water pumps and prop shafts.
One of the major factors in the decision to purchase LiuGong loaders was the price point, says Pick. He says that the LiuGong offering is competitively priced, yet it boasts a range of tried and tested components that make it competitive in arduous mining conditions.
The LiuGong CLG856H wheeled loader is a 17-tonne (t) machine with a 5-t lifting capacity and comes standard with a 3m³ bucket. The machine has a ROPS & FOPS cab, ZF transmission and ZF limited slip differentials.
“The powertrain, for example, comprises a 6LTAA9.3L Cummins engine, Kawasaki pumps and a ZF drivetrain. These are not foreign to us; these are components we understand and trust, and are well equipped to service them,” says Pick.
With efficiency in mind, the LiuGong wheeled loader is powered by the latest fuel-efficient Cummins engine, delivering a net-power rating of 160kW (215hp) at 2,000 rpm. For operational efficiency, the engine uses a precise, high-pressure, common-rail fuel injection system, turbocharger (VGT), air-to-air intercooler, and electronic engine controls to deliver optimal performance in every cycle in every shift.
A special focus on the well-being of operators ensures not only high productivity but also equipment longevity. “Operator welfare is particularly important to us. We always ensure that air conditioners are in good
working condition,” says Pick. The LiuGong CLG856H comes with an advanced climate control system with eight all-around vents, five selection modes and 6kW of cooling capacity, creating the perfect working environment whatever the weather.
Afrigrit’s machines are equipped with mine-spec LED lights, which produce stronger light, and the lifetime is much longer than the standard halogen. This is handy for a 24/7 application where downtime related to any light-changing exercise is unacceptable.
“We are very happy with our decision to opt for LiuGong wheeled loaders. The machines tick all the right boxes for our operations. With that said, every machine is only as good as the service support behind it, and Burgers Equipment & Spares has surpassed our expectations as far as their aftermarket support is concerned,” concludes Pick.

RICH REBUILD RETURNS
Dealer-led or original equipment manufacturer-certified machine rebuilds can offer quarrying customers a highly attractive alternative to investing in new models. Aggregates Business editor Guy Woodford learned this first-hand during a recent trip to Norway with Caterpillar.
There is more to life than the next new thing. Just ask Verdalskalk. The longstanding Caterpillar limestone quarrying customer based in Verdal, in Norway’s Tromsdalen region, has rebuilt five of its Cat fleet over the years - 990, 990K, 980H wheeled loaders, and 775F and 775G off-highway trucks. Carried out earlier this year, the Cat 990K was Verdalskalk’s most recent dealerled machine rebuild.
As Per Olav Listou, key account manager for Pon Equipment AS, Caterpillar’s Norwegian dealer, explains during Aggregates
Business’ trip to see Verdalskalk’s impressive operations an hour-and-a-half’s drive north of Trondheim, a dealer-led machine rebuild typically costs 35% to 40% of a new machine (not Cat Certified). Rebuilds are commonly done at 15,000 hours, depending on the machine and condition, equating to the end of a machine’s first life.
Verdalskalk rented a 988K to replace its 990K during its rebuild. All components were tested to Caterpillar standards, with the rebuilt 990K gaining a new 5,000-hour Extended Protection Plan with a Customer Value Agreement (CVA) - a total repair and maintenance contract.
Verdalskalk’s 990K rebuild was done at Pon Equipment’s new workshop in Trondheim, which opened in January 2023. The 990K was the first machine rebuilt in the new facility, with the project taking two months. The workshop was officially opened on 25 May this year.
Listou notes that operators have a say in the machines that have been rebuilt. For example, they know how the machines handle and if something needs replacing in the cab.
Rebuilds are generally done due to cost (cheaper than buying a new unit) or to access new machine technology.
Verdalskalk’s Tromsdalen Quarry
The Cat 990K rebuild followed the November 2022 rebuild of Verdalskalk’s Cat 988H large wheeled loader. The rebuild included a new engine, bearings, injectors, and gearbox. It is giving Verdalskalk another 6,000 to 7,000 hours out of the machine.
Tromsdalen quarry, Verdal site manager, Kjell Ivar Nonset, says the 988H operator appreciates the higher comfort level after the rebuild because the machine handles better. Nonset is hosting Aggregates Business’ visit on 31 May 2023 alongside colleagues, maintenance manager Petter Jermstad, and mechanic Lars Vergard Hårberg.
Commenting on the Cat 988H rebuild, Jermstad says: “We had a lot of meetings with Pon Equipment to get the correct solution and understand what work was important to carry out.”
Hårberg adds: “Pon Equipment is easy to work with; we communicate well. The Pon Equipment service technician lives locally in Verdal.”
Pon Equipment has 300 service technicians. Most of them work from home to be conveniently located to support the customers. Service calls include free mileage within a 50km radius. “What I like about Cat machines is that they are robust. I like the fact that they can be rebuilt. I think this is a great solution. Not many brands offer that,” says Hårberg.
Verdalskalk was established in 1991 through a merger of the Hylla division of Franzefoss Bruk and Faxe Kalk Norge (formerly Reidar Svendsen & Co) in Tromsdalen and the port of Verdal (Verdal Havn in Norwegian).
Started back in 1897 with the Hylla Kalkverk lime works, today, the NOK 220mn-a-year turnover (€18.86mn) company is a medium-sized family enterprise with around 70 employees distributed between four sites: Tromsdalen (quarry), Verdal Havn (loading facility at the port), Hylla (production facility for high-quality and stable quick lime (CaO)), and a transport department.
The owners of the Verdalskalk production company are Franzefoss Bruk (55%) – owned by Franzefoss Minerals; Faxe Kalk, Denmark (35%) – the Belgian company Lhoist owns FK; and Nordkalk, Finland (10%).
Verdalskalk’s business is based on one of Europe’s purest and largest limestone deposits (CaCO3). The purity and structure of the limestone make it suitable for producing quick lime for all kinds of purposes in various market areas such as industry, agriculture, food, water and sewage treatment, construction products and more. The limestone is particularly suitable for producing PCC (precipitated calcium carbonate) used in environmentally friendly paper production.
The deposit is estimated at 3 billion tonnes of usable limestone down to sea level. The Geological Survey of Norway estimates the total deposit around 7.5 billion tonnes. This makes the deposit one of Europe’s most important carbonate deposits and one of Norway’s most important mineral

resources. Verdalskalk is in the process of regulating a quarry that will allow it to extract limestone for 100 years. First, the quarry will be extended across its surface and then will extract deeper down.
At the Tromsdalen quarry in Verdal, day-to-day operations are performed in an open pit with drilling, blasting, loading and transport, and crushing and fractionating limestone to grades based on market needs. Blasting is done two to three times a month, with the site’s monthly limestone product production ranging from 130,000 to 160,000 tonnes, depending on demand. The temperature at the quarry can drop to -30°C in winter, with the snow lasting until the following April.
Verdalskalk has been buying Cat machines since the early 2000s, with 70% of the company’s fleet now Cat. A CVA covers Verdalskalk’s Cat machines except for the older ones maintained in-house by a mechanic.
On a tour of Tromsdalen quarry, Aggregates Business saw the site’s Cat 775G off-highway truck, 775F off-highway truck, 740 articulated truck, 345D excavator, 990 and 990K large wheeled loaders, 988H large wheeled loader, and 906H compact wheeled loader in action. The 906H is equipped with forks, a bucket and snow plough to keep the site clean and clear of snow.
Before leaving the quarry, Aggregates Business briefly chatted with Franzefoss Minerals’ CEO Hanne Markussen Eek, who spoke of how Verdalskalk was keen to reduce carbon emissions at the Tromsdalen site. Among various solutions being investigated are Swedish company Hypex Bio’s claimed more sustainable explosives for blasting in the mining, quarrying, and construction industries. The explosives are said to be free of ammonia, nitrate salts and NOx gas while ensuring no nitrate leeching. They are claimed to generate a more than 90% reduction in CO2 while guaranteeing comparable performance to standard industry explosives. Markussen Eek says Verdalskalk works closely with Hypex Bio’s Norwegian subsidiary, with the company’s greener explosives due to be tested at Tromsdalen quarry this autumn.
At Verdalskalk’s Verdal Havn port facility, a Cat 988K XE large wheeled loader loads ships. It was purchased because it has a higher bucket capacity than the Cat 988H. It also burns 10 litres an hour less fuel than the 988H it replaces. A Cat 988H is used in various supporting roles. A Cat Productivity trial with the 988K XE only started on 31 May. Verdalskalk runs a Scania battery-electric road truck from Tromsdalen quarry to the port as a test pilot. The company is looking to use zero-emission equipment, and Aggregates Business is keen to be updated with the results from both projects.
Commenting on the Cat 988K XE’s performance at Verdal Havn, Geir Ove Guddingsmo, shift leader and machine operator, says: “It is much quieter than the 988H we previously used as the primary ship loader and runs at a lower RPM than a
standard machine. Putting its bucket into the material is like a warm knife through butter!” Verdal Havn’s Cat 988H was rebuilt by Pon Equipment late last year, giving it up to 7,000 hours of additional working life. “It’s been working fine since it came back to us. We use it when we get the bigger boats in,” explains plant manager Elisabeth Wiik Moe. “We have new ship-feeding conveyors that allow us to load 3,000 tonnes of material an hour. We load six to ten ships a month. It takes around 13-14 hours to load a ship with a 28,000tonne capacity, with the new ship-feeding conveyors halving the time it previously took.”
Around a quarter of Verdalskalk’s annual limestone production (400,000 tonnes) goes to Norcem, a Norwegian cement manufacturer and a subsidiary of Heidelberg Materials. The rest is shipped to other customers. “The 32,000-tonne capacity Norcem ships are the biggest ships we load at Verdal Havn,” adds Wiik Moe.
Later the same day, Aggregates Business visited Pon Equipment’s new 3,500m² facility in Trondheim, where region manager Kenneth Bratseth hosted the magazine.
Replacing a 50-year-old 1400m² site, the new facility is home to Pon Equipment, Pon Energy Rental, Pon Rental, and Sitech. New and used equipment sales and parts, fleet servicing, and machine rebuilds are all carried out onsite.
Bratseth explains that Pon Equipment’s vast customer base stretches 580 kilometres north of Trondheim and more than 150 kilometres south of the city.
Verdalskalk’s Cat 990K was the first machine rebuilt in the new facility. “It was super well planned,” says Bratseth. “Three mechanics, including a trainee mechanic, were allocated to the project under the supervision of the workshop manager. As the work progressed, decisions were made on what to keep and replace. This involved constant communication with the customer. The only big challenge with this job was the axles, where some metal particles had shattered. Replacement axles are not normally kept on our shelves. The project represented 600 hours of work and was completed on time.”
Bratseth notes Pon Equipment’s 40 years of rebuilding experience. The first machine the company rebuilt was a Cat D8 dozer in 1984. He continues: “The viability of a rebuild depends on the age of the machine and the hours on the clock. They are usually done on Stage IV or Stage V emissions-compliant machines.”
Pon Equipment recruits young third-year college mechanics who follow a year of workshop-based training. They are usually retained permanently and thrive, with some promoted throughout the organisation.
“In addition to rebuilds, machines are serviced in the workshop, and new machines are prepared for customer delivery,” Bratseth adds. “Forty mechanics work in the region, mostly based at home with their van to be close to customers. Most Cat genuine parts are available from us within 48 hours.”

Powerscreen is demonstrating its crushing and screening class at this year’s steinexpo. The Terex Materials Processing (Terex MP) business division brand’s team will be located at stand C12 along with its longstanding German distributors - C. Christophel and Jürgen Kölsch. In the exhibition demo area, the Premiertrak PT400X jaw crusher and Warrior 2100 scalping screen will be put through their paces.
The Premiertrak PT400X is an extremely
versatile 400 tonnes/hour capacity crusher used in various applications. User benefits include hydraulic-crusher-setting adjustment for complete control of product size, tracked mobility for optimal flexibility of set-up and crusher-overload protection to prevent damage by foreign objects. With its hydraulicsetting adjustment, the Premiertrak PT400X allows the size of the product to be changed at the press of a button, minimising the need for downtime.
The 700 tonnes/hour capacity Warrior 2100 is engineered to include the proven triple-shaft technology unique to Powerscreen heavy-duty mobile screens. The triple-shaft design ensures the 16' x 5' screen box is highly efficient while maintaining exceptional throughput productivity. The extreme screening acceleration is said to offer the Warrior 2100 improved capabilities over its class rivals, especially in sticky scalping applications. While the Warrior 2100 sits within the same transport envelope as other machines in the 16' x 5' class, Powerscreen says it has been proven to considerably outperform any conventional single-shaft 16' x 5' screen.
Gerry Mulgrew, business development manager at Powerscreen, said: "We are delighted to be participating at this year's Steinexpo with our strategic partners Christophel and Kölsch. Germany is an important market for Powerscreen, and we are excited to return to the steinexpo stage."
Develon, formerly Doosan Construction Equipment, is showcasing some of its wide range of crawler excavators, wheeled loaders and articulated dump trucks (ADTs). This machine trio is said to offer customers from the quarry, mine and construction sectors complete solutions for excavation, loading and transport work, as well as meeting the needs of many application types, from general earthworks to the production of
aggregates and building materials, all from a single source. The company’s static display will include the DX490LC-7 crawler excavator, the DL420CVT-7 wheeled loader and a DA30-7 ADT. The DX490LC-7 crawler excavator is powered by a Stage V-compliant Scania DC13 diesel engine, which provides 257kW of power. The increased power of the DC13 engine is combined with a Virtual Bleed Off (VBO) hydraulic system (D-Ecopower+) and the new-generation Smart Power Control Technology (SPC3) to optimise productivity and fuel consumption, depending on the mode selected.
In the demonstration area, Develon will put its DX800LC-7 80-tonne crawler excavator, DL550-7 wheeled loader and the new DA45-7 4x4 ADT through their paces. The DX800LC-7 is Develon’s second-largest crawler excavator, only surpassed in size by the new DX1000LC-7 100-tonne model.
Terex Washing Systems is highlighting the growth in its waste-processing plant installation business in mainland Europe.
In September 2022, TWS commissioned an excavation waste-processing-plant in Dittingen, Switzerland, some 20 kilometres south of Basel. This project was developed on behalf of Antag, a subsidiary of the independent Albin Borer Group. This processing plant is unique because it processes all the materials generated by the Group's construction sites and recycles them into cuts for the concrete that supplies the company's ready-mix plants.
This is the third end-to-end project that TWS has completed in Europe, from design and specification to supplying the machines. The manufacturer worked with its regional distributor, Avesco, for this project, who completed the installation. It has the capacity to process 480,000 t/yr of materials, and it is due to start accepting materials from the Group's partners later this year.
Antag chose a location to the south of Dittingen, near Laufen, in the district of Basel-Landschaft, as the site for its first fixed processing plant, which will be used to process materials from its groundworks sites. It has been designed to process materials with a clay content of up to 30%, most of which originates from the
region.

Withstanding a full-on crush
High-quality crusher wear parts are invaluable for a big Portuguese construction group. Meanwhile, a new compact jaw crusher from a major brand promises big productivity returns, while another top-flight manufacturer highlights the merits of its trio of crushing and screening drive concepts. Guy Woodford reports
Herdade de Benafessim quarry, owned by Mota Engil in Portugal, has used Metso O-Series crusher wear parts in its tertiary crushing station since 2022 with strong results.
Located in the district of Évora, municipality of Montemor-o-Novo, the Herdade de Benafessim quarry has operated since 1994. One of the 11 quarries of the major Portuguese construction group Mota Engil, the quarry produces aggregates mainly for the internal consumption of the construction group but also for some other, smaller customers.
Being a large international construction group, Mota Engil operates in 23 countries spanning Europe, Africa and Latin America. The group is among Europe's 25 largest construction companies, with holdings in more than 200 companies. Mota Engil has been involved in numerous major infrastructure projects in Portugal, including one of the largest bridges in the world, Vasco de Gama, which rises 150m above the River Tagus in Lisbon and is more than 17km long.
The Herdade de Benafessim quarry processes granite for various needs, including concrete and asphalt production for civil engineering and road construction, and its annual production capacity is more than 600,000 tons. Mota Engil was awarded a significant project in consort with a partner to build the final leg of the Southern
International rail corridor between the town of Évora and the Spanish border. The quarry is producing 31.5-50 mm fraction railway ballast and 0-32 mm sub-ballast for the railway project.
The crushing process in Herdade de Benafessim has three crushing stages. The secondary stage has a Nordberg HP400, and the third stage has a Nordberg HP4, which the quarry obtained in 2022. They also have a crushing line extension with a Barmac impactor to produce sand and asphalt and
concrete fines.
The HP4 operates in a closed-side setting (CSS) and produces two fractions, 6-14mm and the final size, 14-20 mm. The Nordberg HP4 replaced the earlier HP300 in the tertiary stage.
To lower its cost per tonne, the quarry started to use Metso’s O-Series wear parts in the HP300, and based on its good experience with their use, they have extended the same application on the HP400 in the secondary stage. In 2022 they invested in

a new machine and replaced the HP300 with a new HP4. The plan is to continue to use the O-Series wears in the HP4 in tertiary, too, as soon as its warranty period is over. When changing from premium wear parts to the more affordable O-Series range in their tertiary crushing stage, their production capacity experienced a reduction of approximately 10%, but the cost savings are outplaying the production decrease and making their operations more cost-effective.
The quarry has its own modern rock laboratory to analyse the material for the best crushing results. Over the course of time, the quarry has received many quality certifications, including SO 9001, ISO 14001 and OHSAS 18001 and all their products are now CE-marked.
With 20 years left on its licence, the quarry has no plans to slow down. A new bank in the quarry face is in planning to be opened. With that, the quarry plans to move its crushers to a new location, update its equipment and modernise automation to maintain its momentum.
EvoQuip has launched the Bison 340—the newest and largest addition to the Terex Materials Processing business brand's Bison jaw crusher range.
The 34-tonne crusher has a 1000mm x 600mm jaw chamber opening and boasts an impressive output potential of 280tph, depending on application.
A high-performance primary jaw crusher, the EvoQuip Bison 340 is designed for operators in quarrying, demolition, recycling, and mining applications. It features track mobility for a quick setup time and hydraulic crusher setting adjustments for total control of product size. The hydrostatic drive, which is included as standard, allows the crusher to be run in reverse. This is particularly useful for removing blockages from the chamber or crushing in a sticky application like asphalt.
Andrew Armstrong, EvoQuip product manager, said: "As with the entire EvoQuip range, the Bison 340 is compact and easily transported from site to site. The Bison 340
The preconditions for using a Kleemann crushing plant with E-DRIVE are often favourable in stationary recycling. An adequate power supply is often available, even occasionally from an in-company photovoltaic system. Pic: Kleemann

is at home in hard rock quarry applications, as well as recycling applications. It also has an efficient drive system and low engine RPM to enable it to be run with low fuel consumption."
All Bison jaw crushers come with the T-Link telemetry system fitted as standard, providing customers with realtime information on the performance of their machine, leading to effective machine management and maximised uptime. This data can be accessed through a tablet or smartphone and provides comprehensive information on the location, fuel consumption, tonnages, wear ratings,
operating hours, and much more.
Kleemann has highlighted how the company uses three different drive concepts that offer the best solution depending on the crushing and screening tasks. Although electric drives score very well on CO2 footprint, a fuel-saving diesel drive is the better solution in some situations. E-DRIVE, D-DRIVE and H-DRIVE represent the variants diesel-electric, diesel-direct and dieselhydraulic.
The decision on the most efficient solution depends on many factors: For example, whether a power-supply option is available on site, whether the machines are used
in an urban environment or which local environmental regulations apply.
The E-DRIVE concept offers two options: Diesel fuel or all-electric. All-electric operation is environmentally friendly: there are no CO2 emissions on site. A good power infrastructure is a precondition for this, often available in quarries or larger recycling yards. A diesel-electric work option is available if the power supply is insufficient or there isn’t one available, for example, if the complete plant in the quarry is to be moved along the rock face. Power is then supplied from a long cable, which is often too complex or may not even be possible. In this case, power comes from the fuel-efficient diesel engine. The crusher and all conveyor belts are still electrically driven by a generator. Depending on the local situation, the E-DRIVE concept offers high flexibility.
The diesel-direct D-DRIVE provides power directly from the engine to the crusher. In the last few years, it was possible to reduce consumption, for example, through the load-dependent fan drive of the new EVO2 Generation. Concerning the degree of efficiency, the diesel-direct drive has the edge and fuel consumption is significantly lower. Thanks to their compact size and well-thought-out transport options, the machines can be positioned anywhere on the work site. If continuous use of the all-electric drive is not possible, the D-DRIVE is the better, more sustainable choice – whenever flexibility is required. This is the case with demolition and processing work in urban areas and road construction, where the machines have to be moved along as construction progresses.
The screening plants from Kleemann use an effective diesel-hydraulic drive. In this case, hydraulic pumps operate all machine parts such as screen, belts and drive system. The power requirements of the screens are considerably lower than a crusher – fuel consumption during operation is, therefore, more favourable. The optionally available Start-Stop system can reduce consumption even more. With the configuration with Dual Power, Kleemann screening plants have an option for an all-electric power supply. If a mains connection is available, the plant operates on-site free of emissions – for example, in ecologically sensitive areas with strict regulations.
Many factors play a role in the area of sustainability. The energy required for production, transport, storage, sales and disposal are all incorporated into the ecological footprint of the production process. As far as CO2 emissions during operation are concerned, an all-electric plant is, without doubt, the best choice. In other cases, you have to weigh whether supply via an external power source involving high equipment and material costs is more constructive at the end of the day than technology with lower fuel consumption. Ecology can also mean trusting low material usage and high durability. AB
Loaders dig out impressive quarrying performance
Quarry operators are seeing major performance improvements following rollouts of cutting-edge new loading and excavating equipment. Liam McLoughlin reports.
Following a product demonstration day organised by Hyundai dealer CS Matériel at the LRM quarry in Lunel, France, the quarrying specialists were so impressed with the HL975A CVT wheeled loader that they immediately purchased one for use at their new quarry at Pic-Saint Loup.
LRM, which stands for Languedoc Roussillon Matériaux, is 50% owned by Razel Bec (Fayat) and Eurovia (Vinci). The new LRM quarry in Hérault at Liols le Fort covers almost 27 hectares and is licensed to operate until 2047 for up to 500,000 tonnes per year, extracting limestone for concrete production.
The HL975A CVT arrived in April 2022 and had already clocked up almost 1,200 hours of operation by the end of the year. Dedicated exclusively to this quarry, it mainly loads customer trucks and works nine hours daily on-site.
A key factor in purchasing this model was the HL975A’s fuel consumption, operating at 13 litres per hour. “These machines are very economical compared with others, and in the current economic climate, we are more aware than ever of factors like fuel consumption. It’s using around three to four litres less than its equivalent competitor model – the fact that it is a CVT model also makes a difference to its fuel economy,” commented Jean-Marc Boyer, director of LRM.
Benoit Demangeot, operations manager at the quarry, added: “Our number one priority is service, and the dealer has made a huge difference. If we have a problem, our dealer
responds quickly, which is crucial – our machines can’t be inactive; we need them running all the time. We have confidence in this machine and the brand, and above all, we have confidence in Thierry Jacquot of CS Matériel. His serious approach and professionalism make all the difference.”
He continued: “Our operator is full of praise for this model. There’s no lack of adjectives: flexible, robust, comfortable – we can’t ask for more.”
At a lava stone quarry in Sicily, a Hyundai HX520A NL excavator is demonstrating all of its power in carrying out stone extraction and crushing work. Intramoviter specialises in lava stone extraction, crushing, earthmoving and transportation. Its quarry, the true heart of the company, is based in Contrada Incaria, at Belpasso, in the Sicilian province of Catania. Located on the slopes of Mount Etna, the site focuses on extracting inert lava aggregates that stand out for their unique characteristics: lava rock is a strong and particularly durable material used in street furniture and architecture.
Intramoviter is a family-owned company founded in 1990 which handles the extraction and distribution of inert lava aggregates for construction work.
Natale Consoli, a veteran operator with the company, explains: “In this quarry, formed entirely of lava stone, we crush the rocks with a hydraulic hammer, reducing them to pieces of roughly eighty centimetres in size, which are then collected in buckets and loaded on lorries. They are then transported from the quarry to the crushing plants, where
they are transformed into sand, cobbles and chippings.”
The new Hyundai HX520A NL excavator has been operating in this setting for several months - it is equipped with a Cummins Stage V engine, delivering all of the power needed for particularly demanding applications of this type, while at the same time reducing emissions and fuel consumption.
Consoli says: “It is a machine that we really needed for speeding up the extraction phase. The power and the geometric capacity of the boom enables us to reach greater heights - optimising our time and resources. Despite weighing fifty metric tons, this Hyundai excavator is very agile.”
Giuseppe Pappalardo, the owner of Ct Macchine, Hyundai Construction Equipment’s Sicilian dealer, adds: “The customer needed a powerful and sturdy, but also agile, precise and safe machine. In fact, the operation of rock fracturing and extraction is not simple: it is necessary to drill at very precise spots on the slope to avoid the risk of being crushed by large boulders.”
The first EC380E Hybrid excavator from Volvo Construction Equipment (Volvo CE) to be put to work on a customer site in Europe is already proving it can deliver big savings.
The large hybrid crawler excavator is being used by Eichstetter at its gravel works in Fürth, Germany, to extract mountain gravel for use in the production of high-quality building material and aggregates.
Thanks to its unique hydraulic hybrid technology, the excavator can capture and

store the energy generated in the boom down motion to drive the assist motor and power the engine.
Eichstetter is seeing fuel savings of up to 15% in comparison to its conventional machine equivalent.
Family firm Eichstetter is the first in Europe to operate a Volvo EC380E Hybrid. A large crawler excavator, it delivers the same power and performance as its conventional equivalent, but with greater fuel efficiency and lower CO2 emissions.
This is something that Eichstetter is seeing at its gravel pit near Fürth in Germany, where the machine has been operating since Autumn 2022, excavating mountain gravel, the so-called tertiary gravel which was deposited 10-15 million years ago. The company has been measuring the performance of its new machine versus a conventional EC380E – and the results are impressive, with the hybrid technology delivering fuel savings up to 15%.
“The Volvo EC380E Hybrid is more economical,” says Ludwig Eichstetter, co-managing director of Eichstetter. “It has about the same fuel consumption as our Volvo EC300E. But where the EC300E manages about 2,500 cubic metres a day, the Volvo EC380E Hybrid manages over 3,000!”
Volvo CE's hybrid technology generates energy from the lowering movements of the excavator boom.
Featuring unique hydraulic hybrid Volvo technology, the EC380E Hybrid harvests free energy from the boom down motion. This regular and powerful lowering movement pressurises a hydraulic accumulator, which in turn uses this energy to drive the auxiliary hydraulic motor to support the engine system when needed. All this whilst delivering the same level of control and performance as a conventional EC380E, including the ability to operate in ECO and hybrid modes in parallel.
Depending on the type of application, Volvo CE’s hybrid technology promises fuel savings of up to 17% as well as CO2 emission savings of around 15%. And this is something
Eichstetter was determined to put to the test. The firm already had a conventional EC380E in its fleet, so comparing the two machines over a period of weeks was straightforward. The EC380E Hybrid delivered a fuel saving of around 10 to 15% depending on the use and operator handling the machine.
The new EC380E Hybrid fills the Volvo A25G quickly and efficiently - saving up to 15 percent fuel compared to its non-hybrid counterpart.
Ludwig Eichstetter says: “Fuel savings are higher when the machine is optimally positioned on the debris. Lowering and lifting must be in the right proportion so that the energy gain is optimised. To fully exploit this potential, it also depends a lot on the driver. Driving the hybrid machine is a constant learning process.”
Founded in 1938 as a transport company, Eichstetter is a family business specialising in sand and gravel mining, recycling, demolition and earth preparation. Today the firm is led by Helmut and Ludwig Eichstetter and employs 35 people.
Machines from Volvo CE have long been the equipment of choice for Eichstetter, who value their efficiency. The company operates eight Volvo wheeled loaders with operating weights of between three and 45 tons, as well as four wheeled excavators - two Volvo EW160E’s and two Volvo EW220E’s – plus a Volvo EC300E crawler excavator. When the need for a larger crawler excavator became apparent, the firm turned to Volvo CE dealer, Robert Aebi, with whom it has been working for more than 20 years.
Specialist quarrying company CBA has recently taken delivery of a customised ZX350LC-7 medium excavator, supplied by Hitachi Construction Machinery Europe’s approved dealer, Prowimat.
A subsidiary of Eurovia and the VINCI Group, CBA is responsible for the extraction of one million tonnes of aggregates per year. The new Zaxis-7 machine will be based in Hautes-Alpes, in the village of Montmaur.
CBA’s newest fleet addition is intended to replace an older ZX350LCN-5 to assist with loading dump trucks and breaking rocks with a hydraulic rock-breaker attachment. This demanding work requires the most durable of machines, hence the company’s decision to invest in a Zaxis-7 model.

The machine sale also included an extended warranty and maintenance contract. So far, the team at CBA is extremely pleased with its purchase, the customisation provided by Prowimat, and the performance of the -7 model.
Caterpillar has launched the new Cat 995 wheeled loader which features up to 19% increased productivity than the previous 994K model with its higher rated payload and 6% increase in hydraulic force with equal hydraulic cycle time. The new loader is claimed to deliver up to 13% lower hourly fuel consumption and offer up to an additional 8% efficiency gain when operating in Enhanced Eco Mode compared to throttle-lock mode. It is also up to 19% more efficient than the 994K in equal comparisons of throttlelock operation. Enhancements to the front linkage include an improved casting design, increased weld size, larger bearings and pins, and profile changes for increased service
life. New, larger capacity buckets available for the 995 incorporate an extended floor for fast loading, high fill factors reaching 115%, and excellent material retention. Buckets are interchangeable between the 995 and 994K.
Built to the same size as the 994K but offering a higher rated payload, the new 995 is designed to enable a one-pass reduction when loading Cat 785, 789 and 793 Mining Trucks. This equates to up to a 33% increase in production and efficiency when loading the 785, up to a 25% increase with the 789 and up to a 20% increase with the 793.
The new 995 meets the global industry's demand for high production and greater payloads with its powerful Cat 3516E engine offering configurations based on regional needs, meeting EU Stage V/U.S. EPA Tier 4 Final or U.S. EPA Tier 1 equivalent emissions. Its 39% torque rise ensures high lugging forces during digging and acceleration in high rimpull conditions.
Caterpillar is also celebrating the production of the 50,000th Cat wheeled excavator.
In 1984, Caterpillar, Eder and Zeppelin Baumaschinen, the Cat dealer in Germany, introduced a new wheeled excavator line, offering four models under the Cat Eder brand. Eight years later, the line became a 100% Cat product with a designated wheeled excavator team. Twenty-eight years later, in 2012, Caterpillar celebrated production of its 25,000th wheeled excavator. This year, Caterpillar announces production of its 50,000th wheeled excavator, a Cat M318 Next Gen model, adding another 25,000 units to the total in just 11 years.
Europe and South Korea were among the first adopters of this new solution. However, the combination of speed, power, versatility and ability to operate a wide range of hydraulic tools has the Cat wheeled excavator line growing in popularity in China, Southeast Asia, the Middle East, North America and other world markets. Starting with only four models, today’s expanded Cat wheeled excavator line includes seven models – Cat M314 to M322 – for markets with higher emissions regulations, one model – M315 GC – for China, three models – M315 to M320D2 –for those adhering to lower emissions standards, the M323F railroad-specific model, and four materials handlers from the MH3022 to MH3040.
As the authorised dealer for Belgium, Evergem-based Interparts will be showing a wide range of products from Develon, formerly known as Doosan Construction Equipment, for the first time in Belgium at the Matexpo exhibition.
The Interparts stand display will present a comprehensive selection of wheeled and crawler excavators, mini-excavators and wheeled loaders from Develon.
Being held from 6-10 September 2023 at the Kortrijk XPO in the city of Kortrijk, one of the biggest multi-purpose indoor arenas and convention centres in the Benelux region, Matexpo is an international trade fair showcasing machinery and equipment for the construction industry.

On the haul towards lower emissions
A large Australian quarry operator and two major quarrying market players based in Europe are targeting reduced CO2 emissions in the hauling sector, Liam McLoughlin reports.
An articulated hauler from Scotland-based manufacturer
Rokbak is transporting hundreds of tonnes of rock daily at a demanding site that provides important construction materials to locations around southern Australia.
The Rokbak RA30 hauler is operating at Aerolite Quarries, which is based half-anhour north of Geelong in Victoria. Aerolite is a leading producer of construction materials for large infrastructure projects, supplying scoria and basalt-based construction materials to Melbourne and the surrounding area. A very light honeycomb volcanic rock, scoria possesses a high strength rate and low tonnes-to-cubic metre, allowing more product at less weight to be delivered –important as this lowers the carbon footprint.
The nondescript crushed rock is used for road base and overpasses throughout Victoria, and, as one of the region’s biggest scoria suppliers, Aerolite projects often require 60,000 tonnes in mere months. With the RA30’s arrival on site in Anakie, the articulated hauler is assisting the Aerolite operation.
Aerolite Quarries operates on a large scale, supplying thousands of tonnes of construction materials daily to meet the demands of significant infrastructure projects across Victoria.
Since arriving on site, the RA30 has demonstrated its efficiency working in a constant circuit, going back and forth between the fixed plant and the mining area.
“We are flat out all the time,” states Aerolite Quarries general manager Trevor Bartlett. “We’ve done a lot of projects where we are supplying 50 or 60,000 tonnes over a time of a period of months, hence the need for more and more equipment.”
Covering 1,800 hectares, Aerolite Quarries contains two scoria quarries and a basalt bluestone quarry. Excavators fill up the RA30, which takes the material across a distance of 100m to be processed at one of two fixed crushing plants. Aerolite has two large fixed plants, which process between 1,000 to 1,500 tonnes per plant per day.
The quarry operator says the Rokbak is efficient and consistent, with the capability of a 28-tonne haul. The machine's superior traction and stability, combined with its payload, mean it can transport larger quantities of construction materials and maximise productivity. The RA30's advanced articulated steering system also allows for greater manoeuvrability, effortlessly navigating challenging terrains and confined spaces easily.
“The vision and the cameras are very good,” adds Trevor. “There are no blind spots, so the drivers can see everything, which is critical for us. The side mirrors are big,
the camera works exceptionally well, and the view through the windows in all three directions is perfect for us.”
The Australian articulated hauler market is the fifth-biggest in the world. The country consistently sees high demand and experiences an extremely buoyant industry, into which Rokbak is making inroads.
“In Australia, we’ve seen the Rokbak colours go down very well,” says Lee Irving, Rokbak regional business manager. “That sand-coloured aesthetic is distinctive from any other equipment colour, and the brand name is growing and standing by itself.”
Rokbak has further expanded its US dealer network by partnering with Alpha & Omega Equipment Sales and Rental – one of Texas’ leading providers of construction equipment. Rokbak says the new partnership supports its expansion plans, reinforces its commitment to customers and strengthens its presence in this important market.
Alpha & Omega will bring both the RA30 and RA40 to its customers in Lubbock and Midland-Odessa, Texas, who work in industries including construction and mining.
Jackie Johnson Sr., CEO of Alpha & Omega, said: “In Texas, there are over US$35bn of infrastructure projects that will be awarded in the next two quarters. We’ve already had multiple requests for these haulers, and we’re confident that the RA30 and RA40 will contribute to the success of

our customers’ projects and allow us to enter new markets – such as the infrastructure industry.”
Around 60% of the machines that leave Rokbak’s Motherwell factory head across the Atlantic to customers in America. The US is leading articulated hauler demand with huge infrastructure spend and significant construction activity around house and road building. The total articulated hauler market for North America is usually around 3,500 units, with 2022 closing out with an expectation-defying 4,000 units. North American customers currently account for nearly half of the total market, which was just over 9,000 units in 2022.
“As we’ve seen in multiple territories, the Rokbak rebrand has led to accelerated demand in North America,” says Rokbak regional sales manager Dan Meara. “And with that level of interest in our products, expanding our dealer network and partnering with reputable dealers like Alpha & Omega is key to getting our haulers working for even more customers.”
A new collaboration agreement between Heidelberg Materials and Volvo Group is aimed at significantly reducing carbon emissions in the operation of hauling vehicles.
The aim is to jointly investigate and develop how the hauling, in addition to loading, needs of Heidelberg Materials can be solved with the help of electrified vehicles and related services. As part of the agreement, Volvo Group’s emission-free solutions, a mix of its electric trucks and construction equipment machines, will be put to work in several Heidelberg Materials’ Northern European sites and quarries.
In the Northern Europe region, land-based transport accounts for 6% of the valuechain carbon footprint. Electrification of the Northern European fleet can potentially reduce annual CO2 emissions by up to 200,000 tonnes. In addition, electrified vehicles provide a quieter and better work environment.
Volvo CE and Heidelberg Materials aim is to jointly investigate and develop how the loading and hauling needs of Heidelberg Materials can be solved with the help of electrified vehicles and related service
“The partnership with Volvo is a lighthouse project in our industry and has the potential to significantly push the decarbonisation of our entire value chain in Northern Europe. We look forward to working together to identify and implement state-of-the-art solutions for a fast climate transition in the construction sector,” says Heidelberg Materials CEO Dr Dominik von Achten.
Martin Lundstedt, CEO and president of Volvo Group, says: “New collaborative partnerships like this address climate change across the value chain. While we are focused on reducing carbon emissions for both our products and our own operations, we are also committed to helping our customers to lead by example through innovative, well-
orchestrated collaborations that deliver much-needed change.”
A six-month joint feasibility study will evaluate which emission-free vehicle technology and charging infrastructure will best suit the requirements of Heidelberg Materials’ operations regarding operating efficiency, maintenance and charging at the sites. The holistic study will provide a unique opportunity to map, tailor and implement a complete CO2 reduction programme throughout the operations considering transport and loading activities. The project will mainly focus on the larger sites in the region, with the first vehicle in operation at the cement plant in Slite, Sweden, already this summer.
Hyundai Construction Equipment is entering the articulated dump truck market with two new models in its rapidly expanding line of heavy-construction and earthmoving equipment. The HA30A and HA45A have rated payloads of 28 tonnes and 41 tonnes respectively, which the manufacturer says provides an ideal haul-truck match for its larger crawler excavators and wheeled loaders.
Aimed at the popular 30- and 45-tonne sectors, the HA30A and HA45A are built around a full-time six-wheel drive concept, with front and rear limited slip differentials and a longitudinal differential that can be manually locked, for maximum drive and traction on difficult terrain.
The trucks have a compact chassis design, to aid manoeuvrability, with a sloping rear frame and a front-mounted differential integrated into the ZF transmission, allowing for a shorter front-frame section. This results in the smallest turning radius in the sector and outstanding stability. Selflevelling hydro-gas suspension on the front
axle further supports a comfortable ride, delivering maximum tractability in tough ground conditions.
Hyundai has employed powerful EU Stage V-compliant Scania diesel engines to power both trucks. The HA30A uses a fivecylinder, 9.3-litre, DC9 turbocharged diesel, developing 375hp (276kW) and 1,876Nm of torque. The larger HA45A employs a six-cylinder, 12.7-litre DC13 diesel engine, producing a maximum 500hp (368kW) and 2,476Nm of torque.
Finland-based Metso has signed an agreement to acquire Ab A. Häggblom, a privately owned Finnish engineering and manufacturing company. The company’s key offering includes mining truck bodies and buckets. Häggblom's service portfolio includes wear parts, truck body and bucket refurbishments, as well as related field services. Häggblom has partnered with Metso for several years in the manufacturing of truck bodies.
Metso says the acquisition will broaden its offering in bodies and buckets by providing complete end-to-end hauling and loading solutions and strengthening the company’s position in the aftermarket. The aim is to leverage Häggblom's strong engineering and manufacturing expertise in collaboration with existing partners on a regional and global basis.
Heikki Metsälä, president, consumables business area at Metso, says that hauling and loading is a growing business, and the company’s goal is to further develop its capability to serve its customers in this area.
Metsälä added: “Häggblom's product range, manufacturing know-how and engineering capabilities, as well as service expertise are a good addition to Metso's wear-parts portfolio.” AB

Smarter conveying
One leading bulk-conveying solution company is going big on smart stockpiling, while others are making strategic acquisitions and expanding their sales reach.
Guy Woodford reports
Telestack is renowned in the global aggregates market for its bulk-conveying innovations that improve customers’ quarrying operations. One example is the introduction of the 'Self-Driving' smart stockpiling solution, found in the Omagh, County Tyrone, Northern Ireland-headquartered manufacturer’s radial telescopic-conveying range. By deploying technology and experience, this advanced, autonomous stockpiling solution aims to maximise returns within any operation, ensuring operational efficiency, improved site safety, reduced operational overheads and complexity, and a quality in-spec 'blended' product.
The Telestack radial telescopic-conveyor range has a proven record of performance and reliability operating in a range of aggregate applications around the globe. The mobility options of the unit allow the operator to utilise this technology anywhere on site, ensuring a high-production capacity and 30% more stockpile capacity on the same footprint when compared to fixed length/height conveyors. Once set up, the smart system can be operated locally by an operator or remotely using the smart onboard PLC (programmable logical controller) to feed information back to the remote-centralcontrol station. Once the unit's physical constraints are established, the unit can work independently using the pre-programmed parameters determined in the set-up.
The smart stockpiling system starts at a low working angle, such as 8°, maintaining its lowest workable drop height throughout the operation as the stockpile increases in increments. This is compared to a fixedlength unit, for example, that would start at an 18° angle, thus wasting more energy to

discharge the product at a greater height. This also results in a greater potential to compromise the quality of the product due to fracture and degradation caused by material dropping from the elevated operating height. The reduced power usage required for the radial telescopic conveyor ensures that less energy/fuel is used daily. Fuel consumption can be further enhanced by introducing an optional VSD (variable speed drive) by allowing the operator (remotely or locally) to increase or decrease the speed accordingly, depending on the operation's needs.
The continuous, autonomous stockpiling ensures that the blend of the product is maintained throughout the stockpile, and a higher quality product is achievable, ensuring the product is evenly mixed over a wide area. This helps to eliminate segregation, degradation, contamination and compaction, providing a higher-grade product for a lower
stockpiling cost per tonne while reducing labour dependency and costs. There is also a big environmental gain of reduced traffic, dust and noise. The smart system also hosts a range of automatic sensors that guide the independent unit as determined in the set-up. These sensors, as well as safeguarding the drop height of the product, also ensure that the unit will pause when the material has stopped flowing. This ensures the integrity of the continuous stockpile structure, producing an ‘in-spec’ blended product. For example, this would be a significant factor for many in the aggregates sector, where product integrity is critical.
The Telestack range of radial telescopic stackers is available in lengths of 32m (110ft), 42m (140ft), 46m (150ft), 50m (170ft) and 58m (190ft) with possible stockpile capacities up to 200,000 tonnes at 270°. Stockpiling rates range from 100-3,000tph, and stockpile

heights up to 20m (65ft) are easily achieved.
In addition, the option of several PLC automatic stockpiling programmes provides the operator with a versatile, economical and reliable stockpiling system that offers the ability for a radial windrow, incline windrow and radial-conical-stockpile formations, which in all provide a larger stockpiling potential and a radial-stockpiling potential of up to 270° for maximum stockpiling. The smart stockpiling system controls the unit's operation, gathers information, and sends it back to the central control station/ remote location. This helps to troubleshoot when issues arise, giving the controller operational information and specific status updates. In addition, the optional Telestack telematic system Telecore offers remote monitoring and support from the factory to enhance performance. This has proven critical in the operational performance and the unit's general maintenance. Particularly when labour was restricted, for example, during the recent COVID restrictions, the support from the factory was vital in supporting operations through challenging times.
A major UK customer recently purchased a TS-42 radial telescopic conveyor to stockpile aggregate/ scalpings at 1,000tph after a primary crusher and linking system. The fully galvanised conveyor had a host of environmental features, including galvanised dust covers the full length of the outer conveyor, a fully sealed transfer point from outer to inner conveyor, side wind plates on the inner with a retractable canvas cover on the outer conveyor, a spray-bar dust-suppression system and dualaccess walkways for ease of maintenance as well as health and safety benefits. The customised discharge chute also helped eliminate and control dust emissions. This arrangement of dust-management options allowed the operation to satisfy the needs of the local regulations to mitigate potential environmental pollution. In addition, the ability to fully control the operation remotely
(for example, from the central control station) means that the fully automated bulk-material-handling process enhances equipment efficiency and availability, ultimately increasing productivity and lowering operational costs.
The TS-42 installation has proven highly beneficial, and the customer has reported a significant improvement in the quality of the finished product. The benefits are also evident in the operational metrics achieving high throughput and a more efficient, productive, and safer bulk-materials-handling operation. The environmental improvements are also significant.
Specialists in the complete design, manufacture, installation and commissioning of mobile bulk-material-handling systems, Telestack has a globally proven record in a range of applications, including mining and
quarrying, stockyard management, ports & inland terminals, power stations, rail yards, steel mills, cement kilns and many other bulk-material-handling industries and offers a range of solutions and reference sites along the logistics chain from pit to port to plant.
With its acquisition of the US-based Hendrik Group, Beumer Group, a conveyingtechnology major, is expanding its portfolio in bulk-material transport.
“The Hendrik Group specialises in the efficient and environmentally friendly transport of bulk materials. This aligns very well with our goals of bringing sustainable products to the market and improving our customers’ carbon footprint,” said Markus Schmidt, CEO of Beumer Corporation in Somerset, New Jersey, USA.
Founded in 1983 by Henk Hartsuiker and based in Woodbury, Connecticut, the Hendrik Group has become one of the leading manufacturers in the bulk-materials-handling industry with customers worldwide.
Operations manager Rik Hartsuiker believes that his father’s many years of experience and expertise in air-supported conveying technology are now in the best hands: “We hope my father’s legacy is safe in Beumer’s care and are confident that they will be as committed to the further development of air-supported conveying systems as we were.”
“In recent years, we have often had constructive discussions with the Hendrik Group about international cooperation in air-supported belt-conveying systems. The acquisition of this internationally successful company is the logical consequence of these constructive discussions,” said Kay Wieczorek, head of Beumer Group’s Centre of Competence (CoC) Product Business. “The qualitative expansion of our products is a great opportunity for us: we will continue to develop the groundbreaking technology of air-supported belt conveyors for our customers and in terms of sustainability.”

across its Northern Ireland production facilities.
Initially trialled within one production department in Lisburn, County Antrim, the shorter working week has now been rolled out company-wide and sees employees benefit from reduced working hours with no adverse impact on salary.
“Moving to a four-day working week is something we have aspired to for a long time,” comments Jayne Peters, Smiley Monroe’s director of People and Culture. “Employee satisfaction and wellness is at the core of our decision-making, and we have worked hard to put the necessary efficiencies in place to offer this to our team without impacting our output and, most importantly, our customers. We know that our employees will reap the rewards of an enhanced worklife balance and more time to spend with their families.”
The benefits of a four-day week have been well documented, with a 2022 UK trial of 70 companies seeing 86% of participants continue with the policy once the pilot ended. Positive results included happier, more productive employees, reduced stress and illness, savings on childcare and transport, and a reduced carbon footprint. Since the trial, more and more Northern Ireland companies are adopting this new way of working, with successful examples demonstrated within Smiley Monroe’s own customer base.
Smiley Monroe has industry giants such as Terex, Metso, McCloskey, Sandvik, Astec, Wirtgen Group and CDE among its customers. With three global production centres in Northern Ireland, the USA and India, Smiley Monroe targets £100mn in sales by the end of 2027 – three-fold growth in five years.
Chris Monroe, CEO of Smiley Monroe Group, said: “Our vision is to be the numberone partner across our material-processing and recycling world. For us, this does not just mean sales growth - it means being the best employer in our industry, the most sustainable choice for customers and the easiest to do business with. We are delighted to be one of the earliest Northern Ireland manufacturers to adopt the shorter working week, and we look forward to seeing our people thrive under the new scheme. We
will continue to invest in the well-being and development of our team, and I am confident this will enable us, together, to achieve great things that will positively impact our business, our people and our communities.”
Bulk-handling accessories and safety company Martin Engineering is expanding its presence in the Asia-Pacific market by opening a business unit in Malaysia.
Headquartered in the capital city of Kuala Lumpur - with a satellite office in Lumut - the Malaysian business unit will act as the main hub to serve bulk-handling industries such as quarrying, cement, mining, ports, biomass and other sectors in the Asia-Pacific Region.
Martin Engineering says the benefit to customers will be more localised care from a team with a greater understanding of the region’s needs and challenges. It adds that this will result in faster response times, better logistics, closer customer relationships, and expanding the portfolio of products and services available to help customers improve their bulk-handling efficiency and safety.
“Our team in Australia has done a great job of serving this area, but we’ve come to realise that the Malaysian market deserves closer attention,” said Javier Schmal, the
area vice president overseeing the expansion for Martin Engineering. “This is an exciting opportunity to give existing and new customers a greater range of bulk-handling options and innovations.”
The business unit will begin with six qualified collaborators, including experienced professionals like William Valladao from Martin Engineering Brazil. In addition to hiring more qualified local technicians, he will manage and improve support to key accounts and lead customer development. Valladao is a highly experienced member of the Martin Engineering operation. Having worked as a service manager for 20 years in Brazil, he was promoted to business development manager and, in five years, has earned the opportunity to build and drive the success of the Malaysian business unit.
The Malaysian team will speak several languages, including Malay, English, Portuguese, and Tamil.
“The Asia-Pacific market offers one of the best growth opportunities currently,” Schmal concluded. “This new business unit is part of Martin Engineering’s investment and strategic plan to improve our coverage and continue to offer the best service and customer support in the industry.”
The product offerings at the unit will include some of the company’s most popular cleaners, such as the innovative CleanScrape or the QC1+ Light Duty (LD) to Extra HeavyDuty (XHD) models for superior belt cleaning to reduce carryback, dust and clean-up.
Improving the material flow and workplace safety, the Typhoon air cannons with SMART series nozzles allow external maintenance of valves and nozzle replacements without tank removal or exposure to high heat applications. Martin Engineering’s Malaysian team will also deliver fully engineered Total Material Control transition-point retrofits with belt sealing, dust control, belt tracking and belt support designed to improve the conveyor operations of customers throughout the region in any bulk-handling application.

A big-screen institution
A major crushing and screening bucket and attachments manufacturer has big plans for future development after more than two decades of market success. Guy Woodford reports
For more than 20 years, MB Crusher has offered a full line of innovative and patented jaw crusher and screener buckets and accessories for excavators, skidsteer loaders and backhoes of all sizes. A passion for engineering innovation, savvy investment and strong family values have enabled the company to reach internationally recognised excellence.
Founded and still owned by the Azzolin family and headquartered in Fara Vicentino, a town in the Vicenza province of northeast Italy, MB is established globally through its eight subsidiaries, a worldwide network of authorised dealers and service support, and logistic centres on different continents.
Speaking at SaMoTer 2023 in Verona (3-7 May), Alessia Valerio, MB’s communications manager, says at the company’s new 485,000sq ft. HQ, MB manages all phases of its operation, including manufacturing, research and development, and sales. Alessia says a third manufacturing facility at MB's HQ is likely due to strong customer demand. With its complete supply chain control, MB says it can ensure its products are of the highest ‘Made in Italy’ quality.
Since the company's 2001 founding, MB's crusher buckets have spread the idea that the quality processing of inert job site material can create a valuable additional
revenue stream.
Using crusher bucket attachments is said by MB to be the easiest solution for many companies now that construction-equipment procurement is becoming more complex, expensive, and time-consuming. Alessia stresses that they also offer a practical solution when construction sites are located where heavy vehicles have difficulty reaching them due to a lack of connecting roads or are in historic areas with traffic restrictions. Crushing material on-site also avoids moving material from job sites to landfills, respects truck-passage limitations imposed by municipalities, and demonstrates care for the environment by not polluting or exploiting its resources.
Depending on the site's requirements, the 12-strong range of 6.5-100-tonne-excavatorcompatible MB crusher buckets transforms the stones into different sizes. An iron separator installed on the crusher bucket separates the iron portion. During operation, a nebuliser reduces the dust from the crushing. Due to its innovative design, MB crusher buckets can work without problems in closed environments, such as inside sheds and galleries and in urban and historical centres.
MB's screening buckets are designed to select natural materials like pebbles, slag heaps, sand and soils in pre- and post-
crushing phases, reducing the crushing time by 60%.
MB grapples have a 360° rotation and a tilted coupler for a greater range of movement. The company says that all nine grapple models are so responsive that they enable precise selection; the closing graduation allows the handling of recyclable materials such as wood, and metal, separating portions destined for landfill or even controlled demolitions of masonry and urban-area buildings.
MB says its shaft screeners offer an excellent multi-purpose system that can easily process different kinds of material because you can quickly change the shafts directly on-site. They are extremely easy to use and can be simply maintained on-site. MB notes that its new shaft screener is also equipped with a hydraulic shock absorber to reduce shock when changing the direction of the shafts, so the engine, transmission system, and machinery are not damaged.
MB claims its drum cutters are the only ones globally utilising a direct-drive twin motor. The company's novel patent protects this direct-transmission dual-motor system, allowing for a differentiated force distribution on the two drums. This is said to provide an enormous advantage since the drum cutter manages the power force autonomously according to the toughness and resistance of

the material.
During the latest edition of SaMoTer, MB staged the global launch of its new MB-G400 and MB-G500 sorting grapples, and new MB-HDS307, MB-HDS312, and MB-HDS412 padding buckets.
Asked why MB is introducing the new grapples and padding buckets, Alessia says: "It is filling a gap in attachments for medium compact excavators. In Europe, especially, there is big growth in this area. You want to take a medium compact excavator to your work site rather than a large excavator as it is cheaper, and you want attachments that work best with a medium compact machine. With our attachments, you can crush, screen, and recycle on-site – a full materials-processing operation without bringing in trucks to transport material by road for further processing. This is also good for sustainability.
"You can use one machine and change between our attachments for different jobs and material types while crushing and screening buckets and other attachment maintenance is done on-site. Respecting [client] deadlines is a huge necessity, and we help our customers do that by reducing production downtime. The current shortage of building materials is also increasing demand for attachments that can process materials on-site and meet customer-delivery expectations."
Alessia says that MB's product range appeals to a broad range of construction, quarrying and building materials recycling customers. "You have companies that may, say, specialise in demolition, but on the side, they do some recycling and make aggregate products from that. You may want to separate topsoil from recovered materials; we have attachments that can do that. Our attachments are compatible with any on-site customer carrier."
MB has developed a crusher and screener bucket performance-monitoring telematics solution currently only available to Italian customers. "Once perfectly tailored to the Italian market, we will introduce it more widely. A lot of Italian companies are using Industry 4.0. It is a big benefit to various
industrial customers," explains Alessia.
A 250-plus employee company, MB has, says Alessia, worked hard over many years to build its global distribution setup, which is coordinated out of ten regional branch offices.
Turning her attention to the evolution of MB's manufacturing processes, she continues: "We opened our second manufacturing facility next to our existing HQ manufacturing site just before COVID
[2019]. Our laser and welding robot machines were another key investment. A third manufacturing site will surely be needed in the future.
"We are always employing people. It is a good growth indicator. We are also always looking for ways to respond to market demands. MB never stops!"
Finding an effective way to separate and screen materials directly on-site is vital for cost and time-saving-conscious construction and earthmoving fleet operators.
Available in six models for excavators from 1.2 to 45 tonnes, Simex VSE screening buckets are specifically designed for separating different-sized materials directly on-site. The VSE product range features the rapid adjustment of output size via an instant control in the cabin. This exclusive patent allows the shafts to be instantly distanced and closed, with a maximum travel of 40mm.
Simex’s FIT screening tool technology, another standout feature of VSE screening buckets, remains popular with customers two years after its introduction. The low-maintenance system allows for the easy interchange of every single disc or blade without unstrapping shafts. The Italian company says this means 75% less maintenance costs than the previous system. Multiple configurations are possible, depending on the materials to be screened. Simex offers users four different set-ups, but many others are possible thanks to the 100% interchangeable screening elements.
Recently in the Yorkshire Dales in

northern England, Simex dealer Mouse Valley Equipment used a VSE 10 screening bucket coupled to a CAT 307D crawler excavator. The attachment worked with different materials, including soil and demolition waste. Reclaiming soil directly on-site results in net savings, avoiding the huge costs of purchasing and transporting new raw materials and significantly lowering disposal costs. The screening operation using a VSE bucket supplies the dual advantage of saving in disposal – delivering only a minimum of the total material – and supplying new soil for refurbishing green areas. The land reclaimed and cleaned from debris is immediately usable, aerated and of a size suitable for subsequent planting.
Given the uncompromising weather and material conditions, the chosen ‘aggressive configuration’ comprised only bladeequipped tools. Simex says this configuration was created to handle more compact materials where, in addition to separation, it is necessary to shake off soil adhering to stones, roots, gravel and demolition waste.
Despite the high soil humidity caused by the heavy rains in the hours before the application, production was still efficient. The instant variation of output size, through a control in the cabin, has also accelerated the processing time necessary for material separation. With Simex screening buckets, the company says there’s no need for long and complicated technical operations to
change the output size, adapt to different materials by distancing the shafts, or change the screening tools.
Simex VSE screening buckets aim to sustainably recover and reclaim soil and aggregates resulting from demolition, helping
deliver a circular economy.
The new VD Drum from Finnish manufacturer Allu enables you to replace fixed TS blades quickly, and there is no need to open the chain box when blades are replaced. Enabling a variable drum setup

means an individual drum or blade can be changed quickly, saving time and money.
Allu’s patented TS (top screen) construction and screening blades make it possible to screen materials even when wet or moist without fear of the structure getting clogged. With the TS structure, getting three different fragment sizes from the same Allu unit is possible by rearranging the screening combs with no additional costs.
Allu Transformer D-series attachments are said by the manufacturer to be versatile and reliable tools for industries, including quarrying, enabling efficient screening and crushing of materials.
The D-series screener buckets are designed for larger processing jobs. Everything from aerating compost to primary on-site screening and processing construction material. This bucket screens, crushes, pulverises, aerates, blends, mixes, separates, feeds and loads materials. And best of all, it transforms the materials you work with. It’s more productive and more profitable.
Allu says it has been consistently one step ahead, leading the industry for over 35 years, with truly mobile, compact screening buckets, which are the perfect attachment for compact base machines to screen and transform your materials.

Major acquisitions in water tech sector
McLanahan, Xylem and FPS have all recently finalised significant acquisitions in the dewatering and water technology sector. Liam McLoughlin reports
Aggregates-processing solutions company McLanahan has finalised the acquisition of Diefenbach, a leading manufacturer of filter presses and thickeners based in Medolago, Italy, which was first announced in February 2023.
Diefenbach has been designing and manufacturing liquid-solid separation equipment since 1907. With thousands of installations around the globe, the company provides solutions for filtration and dewatering applications in a wide range of industries, including aggregates and mining.
McLanahan and Diefenbach have been working on projects together since 2013. This new partnership will allow McLanahan to serve their customers better worldwide, offering a more comprehensive waterrecycling and tailings-management solution and contributing to sustainable materialsprocessing practices as part of the circular economy.
“As the focus on sustainability and creating a circular economy within the materials-processing industry continues to grow, the need for water-recycling and tailings-management is more important than ever,” said Cory Jenson, executive vice president of sales and business development at McLanahan.
“This acquisition complements McLanahan’s existing line of tailings- and water-management solutions and will allow us to offer more competitive solutions to our customers around the globe.”
Diefenbach will continue to operate as an independent brand in the marketplace and support its customers globally. For the aggregates industry, Diefenbach is partnering
with Eagle Iron Works (EIW), another brand in the McLanahan family of companies, to provide a proven line of filter presses and thickeners to EIW customers who are looking to purchase a complete tailings-management and water-recycling solution from a single vendor.
McLanahan is helping Newcastle Sand - a mining operation located in Williamtown, New South Wales, Australia – increase production with a sand-washing plant featuring a highly efficient dewatering screen.
When Newcastle Sand commenced operations in 2019, the company opted to dry wash its sand products with an air separator. However, rainy days would put a damper on the dry process, so Newcastle Sand purchased a small-scale wash plant consisting of a small screw washer.
In 2020, Newcastle Sand experienced
an increase in demand for washed sand. The company supplemented its small screw washer by adding a higher-volume wash plant to increase production.
But even with the two wash plants, the smaller one and the higher-volume plant, Newcastle Sand was still struggling to meet the demand for washed sand.
“We sought to find a screw washer that could increase our production to keep up with the current market demand,” said quarry manager Eliott Laver.
Laver had a previous relationship with Lincom, McLanahan’s dealer for aggregates wet-processing equipment in Australia, prior to joining the Newcastle Sand team. Working with Lincom and McLanahan, Newcastle Sand installed a McLanahan Fine Material Double Screw Washer and UltraDRY Modular Dewatering Screen.
McLanahan has been helping Newcastle Sand increase production
Newcastle Sand’s McLanahan UltraDRY Dewatering Screen
The McLanahan Fine Material Screw Washer washes, classifies and dewaters Newcastle Sand’s washed sand product, while the UltraDRY Dewatering Screen removes excess moisture from the final product. An integrated sump underneath the UltraDRY Dewatering Screen captures the water that is removed from the sand product and recirculates it back to the screw washer via a pump to aid in the washing process.
Since installing the McLanahan wash plant, Newcastle Sand has more than doubled its production. “That allows us to produce more quality washed sand product,” Laver said. With the UltraDRY Dewatering Screen reducing the moisture content of the final product, Laver said Newcastle Sand is able to sell the product straight from the belt, minimising stockpile requirements.
deeper and further, making operations more efficient, sustainable, and safe.
“Being able to sell our material straight off the belt rather than stockpiling and letting our material dry allows us to reduce the amount of haul times, reduce our product movement or handling,” explained Laver.
In addition to being able to sell the product more quickly, Newcastle Sand has experienced additional benefits from the UltraDry Dewatering Screen, such as improved site housekeeping and recirculation of water back to the wash plant.
“The McLanahan UltraDRY Dewatering Screen allows us to keep our stockpiles clean and tidy,” Laver said. “We have less water runoff, and we’re able to harvest that water and reuse it in the wash plant.”
He added, “We’re able to recover up to 90% of the water from our washing process. In turn, we recycle that water, reducing our environmental footprint in the location.”
Water technology and dewateringsolutions company Xylem has completed its acquisition of Evoqua Water Technologies, a provider of water-treatment solutions and services.
Xylem says the US$7.5bn all-stock transaction creates the world’s most advanced platform of capabilities to address customers’ and communities’ critical water challenges. Xylem provides water and pump technology for global industries including quarrying.
Patrick Decker, president and CEO of Xylem, says that the combination with Evoqua creates a global platform to solve critical water challenges at an even greater scale.
He adds: “Global awareness of water as a systemic risk to society has never been greater. Investment in water solutions continues to accelerate as communities and businesses around the world address intensifying challenges like water scarcity, quality and resilience to climate change – and how to address these issues in an affordable way."
Washington, D.C.-based Xylem says the combined company becomes the world’s largest pure-play water technology company, with US$7.3bn in pro forma revenue and more than 22,000 employees globally. Xylem adds that its portfolio of solutions
across the water cycle, including advanced technologies, integrated services, and deep application expertise, will help customers in utilities, industrial and commercial end markets address their most pressing water needs.
The combined company's executive leadership team will be led by Patrick Decker and include senior leaders from both Xylem and Evoqua. Xylem has also appointed Lisa Glatch and Lynn Swann, former Evoqua directors, to serve as members of its board of directors.
Xylem announced in August that it made total revenue of US$1.7bn in the second quarter of 2023, with reported growth of 26% and organic growth of 15%, surpassing prior guidance. The Q2 results include the acquisition of Evoqua Water Technologies.
Xylem says that orders were up 10% on a reported basis and down 2% organically, while backlog grew to US$5.3bn, up 7% organically and including US$1.3bn from Evoqua, with resilient underlying demand.
Second-quarter earnings, excluding the acquisition, exceeded Xylem’s previous standalone guidance.
Xylem has released a new dewatering pump which it says has been developed to significantly increase efficiency, cut costs, and minimise downtime for construction and mining customers.
It adds that the Godwin HL270M Dri-Prime Pump is designed to meet the unique demands of deep-mine and highpressure water transfers and can deliver cost savings of up to 10% compared to competing solutions.
With greater hydraulic efficiency and optimised head and flow, it reduces the need for multiple pumps in series, lowers energy consumption, simplifies operations and maintenance, and minimises premature wear. Field-test participants have already used the pump to meet project goals with fewer assets, simpler operations, and reduced maintenance costs.
The solution, part of the Godwin Ultrahigh-head range, also enables operators to lower carbon emissions.
“Meeting the evolving needs of our customers is paramount,” said Mike Ramos, global product manager at Xylem. “The Godwin HL270M meets the unique demands of deep-mine and high-pressure water transfers. It allows our customers to go
“This product is also a great example of a sustainable and smart business. The pump uses less power, reduces the need for multiple pumps, minimises premature wear, and offers longer life between repairs.
Thompson Pump has announced that its distributor Florida Pumping Solutions (FPS) is expanding its services with the acquisition of Northern Florida-based socking company American Sock & Dewatering.
FPS says the addition of American Sock means it can now provide a full range of dewatering services
FPS is a distributor for Thompson Pump and Manufacturing Company, a manufacturer of heavy-duty, diesel-powered bypass and dewatering pumps.
With the addition of American Sock, FPS says it is able to improve the customer experience by now providing the full range of construction dewatering services, from start to finish, including socking – a technique used to prevent water intrusion during excavation and construction, slurry pumping, bypass pumping, emergency response and more. This allows FPS to meet the unique North Florida challenges such as low-lying terrain, coastal areas and heavy rain and flooding which require effective dewatering and flood-control solutions for construction, agriculture and other industries. FPS says it is excited to be at the forefront of delivering cutting-edge pumping services to clients, especially with the help of Thompson Pump.
“This move not only cements us as a leader in the pumping industry, but it ensures we are supplying even greater value to our customers – with more efficiency and faster project completion times, helping to cut down on costs,” said Jay Friemark, general manager at FPS.
Thompson Pump provides multiple models of dewatering pumps with a focus on rotary and piston pumps, as well as vacuum-assisted models, for wellpoint and sock underdrain.
FPS is headquartered in St. Augustine, Florida, and offers a range of services including sales, rental and service of Thompson Pumps.
Atlas Copco has developed a new range of electric surface self-priming dewatering pumps for various applications.
The E-Pump range comprises the E PAS and PAC electric models, which feature a canopy and open set configuration. Atlas Copco says this flexible solution is ideally
Xylem’s new Godwin HL270M Dri-Prime Pump
suited for many applications like sewage bypass in the municipality sector and construction projects with access to a power source. It adds that E-Pumps can successfully manage demanding flows and large solids with a lower total cost of ownership (TCO) and no CO2 footprint during pumping operations with digital connectivity solutions.
The manufacturer says the new range offers an electric, no-CO2-emission alternative to diesel-powered surface dewatering pumps during pumping operations. This allows customers to reduce their emission footprint and operate in emission-restrictive areas with no fuel consumption. While the PAC electric pumps, an open configuration range with a galvanised frame, will mostly address the North American market, the E PAS is designed with a canopy to meet European customer needs.
The E PAS features an intelligent priming solution to ensure that the pump’s priming system only runs when necessary, reducing energy consumption and noise generation under normal operating conditions. Atlas Copco says the E PAS model emits reduced noise levels, making it ideal for noisesensitive environments. The priming system ensures no carryover contamination, and the canopy set units are up to 120% spillage-free, keeping the workplace and environment clean. E PAS dewatering solutions can intelligently start and stop based on float signals.
The operating expense of the E PAS is up to 40% lower, depending on the difference between local diesel and electricity costs. Also, electric motors' maintenance and servicing costs are substantially lower than diesel engines. Time to service is less with patented hinge doors for easy access to serviceable parts.
The E PAS model features Atlas Copco’s
variable speed drive (VSD) solution, increasing the efficiency of the pump and offering energy savings of up to 40% with an extended pump life.
“The E PAS and PAC electric lines of surface dewatering pumps are an exciting addition to the electric-powered range of products from Atlas Copco,” says Saksham Dube, global marketing manager at Atlas Copco Power & Flow. “They offer excellent performance, low cost of ownership, reduced footprint and unique digital connectivity, contributing towards Atlas Copco’s efforts to create a more sustainable future.”
Tsurumi Pump has partnered with Briggs and Stratton to offer North American users its engine-driven trash and dewatering pumps another choice and continuously high aftersales support. This enables popular models in Tsurumi’s EPT and TE series to achieve compliance with the latest regulations of California’s Air Resources Board (CARB) and allow them to be sold in the state.
The Vanguard Series engines will offer the same horsepower and RPM figures and be an
option on 2” and 3” centrifugal dewatering pumps and 2” and 4” trash pumps under the TE3-50V and TE3-80V, and EPT3-50V and EPT3-100V model designations, respectively.
Standard features on Vanguard singlecylinder engines include an integrated cyclonic air cleaner that doubles air-filter replacement intervals to 600 hours, an acoustically designed fuel tank and muffler optimised to reduce noise, and easy, one-pull starting in cold temperatures as low as -20° F.
Japan-headquartered manufacturer Tsurumi says that its agitator pumps deliver dependability in slurry applications
The company adds that its agitator pumps are made with wear-resistant components like high-chrome impellers and hard castiron volutes that demonstrate outstanding performance and durability when handling abrasive materials.
One of the largest challenges that contractors face when pumping slurry water is finding the right equipment to efficiently and seamlessly complete the job. Pumping from pits that contain sand, grits or debris requires heavy-duty equipment, specifically designed to handle abrasive materials to work continuously without failure. Tsurumi states that agitator pumps are the answer.
Agitator pumps utilise an agitator propeller that shares the same shaft as the pump's impeller. While the two spin in the same direction, the agitator blades are in the opposing orientation to those of the impeller. The agitator provides a propelling force to stir up solids near the floor while the impeller pumps the now suspended solids along with the fluid. They keep the mud circulating to avoid solids from settling while allowing pumping to continue without obstructions.
“The use of agitators in coal mines and quarries is well known, but not everyone is aware that they can be used for any liquid containing solids that needs to be pumped,” explains Kevin Boicken, Southeast regional sales manager at Tsurumi Pump.
“We recently installed an agitator at a construction site that had solids suspended in the water being pumped. A standard dewatering pump could become suffocated by sucking the solids to the small hole screen, preventing the liquid to be pumped.” AB

Increased sustainability in the asphalt-plant mix
The world’s asphalt-plant market is increasingly focusing on green and smart-technology solutions, with many major asphalt-plant manufacturers offering eye-catching, cutting-edge products to tempt more sustainability-minded and contract-securing-savvy customers to invest in their solutions. Guy Woodford reports
Marini, a Fayat Group company, has been busy explaining the significant sustainability gains of its asphalt-plant solutions to both customers and potential customers.
Established in 1899 in Alfonsine, in the Ravenna province of Emilia-Romagna, Marini is among the world leaders in its field. The company’s comprehensive asphalt-batchingplant range includes the Master Tower, Class Tower, Top Tower, Be Tower, and Xpress. The adjacent Ermont brand also offers continuous asphalt plants in mobile, transferable and stationary types. Additionally, Marini has a polymer modified bitumen (PMB) plant and SAE cold-mix plants, a Fayat Group speciality.
Marini customers can also benefit from the company’s technical services and ZEROVOC production-assisting technology, combining the AeroFILTER with the EvoDRYER system. ZEROVOC delivers effective and efficient asphalt-plant fumes management and treatment of VOC (volatile organic compound) emissions.
AeroFilter is a filtering system for fumes and blue smoke produced at certain points of the asphalt plant, such as the mixer discharge or along the skip track if the plant is fitted
with a lateral storage bin plus the truck discharge points.
Filtering takes place in a series of steps, and the oils are recovered in the lower part of the hopper before being evacuated through special tanks without any external dispersion.
The treated fumes can be sent to the plant stack or receive further heat treatment in the
EvoDRYER.
As well as the benefits and improved performance with RAP (reclaimed asphalt pavement) use, the EvoDRYER system also provides heat treatment of the fumes, which could contain classified substances such as VOC.
The conveyed air is fed behind the burner flame through a special cylinder entrance.
This patented system means the air is distributed around the external periphery of the combustion chamber where the fumes are said to be quickly and effectively treated, and the residual organic composites of the gases are eliminated.
Speaking at Asphaltica, staged in conjunction with the 31st edition of SaMoTer in Verona (3-7 May 2023), Roberto Berardi, Marini-Fayat Mixing Plants product marketing manager, says: “Many asphalt producers, particularly bigger companies in France and other countries in northern Europe, are speaking about the need to reduce their carbon emissions and investing in solutions that can do that. Many smaller Italian companies have historically been keen to reduce spending on asphalt plants. We are saying to them, ‘If you spend a bit more, you can greatly reduce the impact on the environment while also reducing your energy
Roberto Berardi, Marini-Fayat Mixing Plants product manager, at Asphaltica & SaMoTer 2023
and other production costs.’ We are trying to develop different kits and ‘softer’ solutions for these companies.”
Berardi continues: “The kits we offer to large and medium-sized customers can be retrofitted to their plants or fitted on a completely new plant. For example, our Master Tower has a patented system that uses up to 100% RAP. The main difference in this system is that it has one burner that heats two drier drums, one for the aggregate and the other for the recycled material. This gives more production flexibility.
“For medium-sized customers, we also offer a parallel [dryer] drum that can be installed on an existing asphalt plant. It guarantees that you stay within permitted emission levels. It is longer, bigger and offers excellent recirculation of air. It means that the flame stays in the centre of the burner and does not come into contact with the material. It means you don’t risk burning the old bitumen in recycled material, and as the drum is longer, you have more time to reach up to 70% of recycled material without an emissions problem.”
Berardi says that domestic-market encouragement to increase the RAP used by Italian highway asphalt-works contractors and the need for better production temperature control may lead to new guidelines that encourage contractors to invest in more sustainability-minded asphaltplant solutions from Marini and other leading sector players.
Marini’s plant-control software includes kits that optimise the thermal exchange between the hot air created by the flame and the aggregate. “According to the temperature of the fumes, the software automatically adjusts the speed of the dryer-drum’s rotation to maintain the quantity of material inside the drum, which is especially important when working with a percentage of RAP,” explains Berardi.
Berardi says Marini is working on introducing more predictive-maintenance features for its asphalt-plant range. “They involve sensors that analyse plant-supportbearing vibrations and trigger alerts if they exceed a certain level. This allows technicians to make necessary changes to components. This is very useful for customers, especially those running just one or two plants, who may not have the same experienced plant-maintenance people they used to.”
Commenting on the health of the Italianasphalt plant and supporting-services market, Berardi says: “Generally, the market is good. The last two or three years have seen big fiscal incentives offered by the Italian government and the EU, encouraging customers to invest. The incentives are now less, so the market presents new challenges. However, we can continue doing good business in machine sales and servicing existing customer asphalt plants.”
Asphalt-plant manufacturers have made great strides to reduce emissions over the last decade. Advanced baghouse filters, improved
combustion processes and alternative fuel sources are among the improvements.
And now, emissions reductions are being fought on a new front: during the loading process. Ammann is leading the industry in these efforts with Ammann Blue Smoke Treatment (BST).
BST captures vapours that previously escaped during loading. With BST, the trapped fumes undergo a filtration process where oily particles are removed, and the remaining gas streams are sent to the burners.
“BST is a win for plant owners on all counts,” said Mathias Halter, Ammann’s sales director for Europe, the Middle East and Africa. “It’s the answer the industry has been looking for.”
Blue-smoke emissions have been around since the advent of asphalt-mixing plants. The smoke released during loading resulted from the extremely high temperatures required in production.
The temperatures were a necessity.
Therefore, little could be done to stop the smoke.
New regulations are requiring that steps be taken to mitigate blue-smoke fumes. It’s a challenge for industry professionals, but Ammann has found an answer with BST.
• BST captures the fumes and redirects them to a multi-stage filtration system.
• The filters remove the oily particles during multiple filtration stages, ensuring high efficiency and allowing the remaining gases to be re-used in the combustion process.
• The condensed oil that accumulates in the filtration system can be recycled.
• BST enables a steady flow rate at the chimney, a key factor in controlling NOx and CO emissions. Therefore, BST is not a case of solving one problem and creating another.

over 600,000 tons of
BST is a cost-effective solution. The filtration system is highly efficient and inexpensive and does not require complex and costly confinement methods.
The BST system is green from start to finish. Diffuse emissions are removed, pleasing those at the plant – including operators, haul truck drivers and other workers near the loading dock. Those who live near the plant are thrilled at removing the fumes.
This new innovative technology by Ammann is already in use with expected results in several of the company’s plants.
“This is a significant development on the sustainability front,” said Marzio Ferrini,
Ammann’s product marketing manager. “Blue smoke is a challenge the industry has faced for years – and Ammann has found an answer.”
Lintec CSM containerised asphalt-mixing plants have played a major role in helping to improve local transport conditions by opening up central Pakistan's north-south traffic arteries of the Peshawar-Karachi motorway (PKM).
Lintec & Linnhoff China sold two Lintec CSM4000 containerised asphalt-mixing plants to established customer PowerChina Group to support the construction of KPM's 392km M-5 section.
The asphalt-mixing plants were installed
in December 2017 and March 2018, with the first providing 34.1km of new asphalt road and the second covering a stretch of 29km, with three lanes in either direction. Both plants had produced over 600,000 tons of hot-mix asphalt by the time the project was completed in November 2019, 13 days ahead of the 36-month schedule. The new M-5 section of KPM is helping slash travel time from Sukkur to Multan by two thirds.
During the construction of this large-scale project on Pakistan's longest motorway, there was a lot of demand for the asphalt-mixing plants' rapid assembly and disassembly capabilities and mobility. These challenges proved no problem, as Lintec's CSM range offers clear advantages, with its 100% ISO shipping-container design facilitating easier and more economical transport and removing the need for concrete foundations. The pre-assembled modular construction also speeds up assembly.
"We had already purchased several Lintec asphalt-mixing plants, including the CSM and CSD models, for other international aid projects since 2010, so we knew we could easily achieve a fast set-up time," said Mr Chen, project manager at PowerChina. "But just as important was knowing we could depend on reliable performance and smooth operation because these were challenging conditions, with the local temperature passing 40°C, which can damage some equipment. To adapt to the local hightemperature environment, the project adopted a new standard of rutting-resistance technology for road asphalt mix at 80˚ C. Due to the high batching accuracy of the Lintec CSM4000 asphalt-mixing plants, this recipe was smoothly implemented, ensuring excellent quality of the road surface."
To adapt to the extreme environment and heavy workloads, the project adopted a new standard of rutting-resistance asphalt for the road surface, capable of withstanding high temperatures up to 80°C. Due to the high batching accuracy of the CSM4000 AMPs, this recipe could be smoothly implemented, ensuring consistently high quality for the surface and providing resistance against even extreme floods.
"As a state-owned enterprise working on an international aid project, our client places the greatest importance on the production safety and stability of its equipment," said Tony Liu, CEO of Lintec & Linnhoff China. "Lintec's reputation as a leading brand of German heritage gained widespread recognition and a reputation for safe operation, batching accuracy and mobility performance. This is why we are an everpresent partner in projects under China's Belt and Road Initiative."
The 1,152km, US$2.889bn PKM expressway originates in Karachi, passes through Lahore, and terminates at Peshawar in the northwest Khyber Pakhtunkhwa (KPK) province. As the China-Pakistan Economic Corridor's largest transport infrastructure project, it is speeding up access to China's western border. AB

Benninghoven sustainable asphalt production for today and tomorrow
How do you get the biggest sustainability ‘bang for your buck’ in today’s US$4bn-a-year global asphalt-plant market? It’s a question dominating plant operators’ minds worldwide and one to which major premium asphalt-plant and linked-solutions manufacturer Benninghoven offers a cogent response. Guy Woodford reports
Whether you want to lower your carbon emissions via warmmix (low-temperature asphalt) rather than hot-mix asphalt production, make greater use of RAP (reclaimed asphalt pavement] in your asphalt mixes, switch to powering your asphalt production with low- or zero-carbon alternative fuels, to retrofit your asphalt plant to improve its eco-minded efficiency or incorporate all those worthy aims in your future business delivery, Wittlich, southwest Germany-based Benninghoven’s continuing large investment in research and development (R&D) and its comprehensive modern product range leaves it well placed to meet customers’ greater sustainability expectations.
Aggregates Business recently spoke to Benninghoven general manager Heinrich Steins and the company’s head of R&D, Steven Mac Nelly, to get the latest on the Wirtgen Group brand’s approach to sustainability, other key market trends and where Benninghoven sees its biggest growth opportunities during the next few years.
At the large cutting-edge production facility within the company’s €130 million state-of-the-art HQ, Benninghoven produces mobile and stationary 100-400tonnes/hour asphalt-mixing plants, capable of handling up to 100% reclaimed asphalt pavement (RAP). Benninghoven is gaining wider market
recognition for its innovative modular system and intelligent connection technology, making assembly easier. Steins stresses that the company also produces high-quality, maintenance-friendly components for all its plants.
“Out of the modules, we can build different plants. From a manufacturing perspective, we brought a new approach to the old industry. We manufacture modules and test their functionality within our factory so that we know the senior components are functional and can bring the modules together on a customer site; we know that the quality is there and the plant will function,” says Steins.
Benninghoven’s asphalt plant types – ECO, TBA, and RPP – feature the company’s BLS 4 control systems. The firm also produces its own asphalt-plant combustion (burner) technology, with burners available in five sizes, and carries out full asphalt-plant retrofits.
Steins continues: “Sustainability is a subject growing at different rates of speed in different markets. However, many solutions require new investments. The way to finance this is by increasing your use of RAP, which will lower your production cost and increase your margin as an asphalt producer or road construction company. In some regions of the world, RAP costs nothing. With those achieved savings, you can afford to invest in future technologies and drive sustainability forward.”
Steins says customers also increasingly want to consider alternative fuel options, including green hydrogen, to power their asphalt plant’s material-drying. This and other sustainability-minded production shifts are, notes Steins, due to tougher EU and other big regional and national government environmental legislation and new greenminded works-contract stipulations. To keep global warming to no more than 1.5°C – as called for in the Paris Agreement – carbon emissions must be reduced by 45% by 2030 and reach net zero by 2050.
“All this is driving huge change in the entire industry,” says Steins. “In several Scandinavian countries, if you are part of a tender for a road construction project, you get preferred treatment if you can prove that you can reduce your carbon footrprint during the works and your competitors can’t. Some countries have carbon-tax legislation coming in, and the US has gone for a huge Green Deal. In South America, Brazil is considering increasing the recycled material used in roadbuilding by classifying it as raw material. It’s also coming at different levels in Asia.”
From a Benninghoven perspective, Steins re-emphasises that the company meets the growing customer need for more sustainable asphalt-plant technologies. “CO2-avoidance
At its brand headquarters in Wittlich, Germany, Benninghoven develops and manufactures sustainable solutions in the world's largest and most modern asphalt-mixing plant factory. Pic: Benninghoven
technology is big in Europe, North and South America, and an important part of those regions’ futures.”
Focusing on the market shift to warm- and cold-mix asphalt production, Mac Nelly says: “It differs between regions what they mean by warm and cold mix. In the Netherlands, they mean 110˚C; in Germany, they could mean 150˚C [compared to 170˚C-175˚C for hot mix]. That’s a big difference. The technology for this is not new. We have offered foam bitumen systems for over 13 years to customers in various countries, such as the Netherlands, Norway, and Sweden. What needs to be extended is the long-term quality check. How is the marketplace quality of the warm-mix asphalt produced with a foam bitumen system and some additives supplied ten years ago?
“Some studies already show that the longterm quality of LTA [low-temperature asphalt] is comparable to that of conventional asphalt. However, the effects of additives on the next life cycle (re-recycling) in terms of quality and emissions during production and processing need to be examined more closely.
“I would add that even with warm- rather than hot-mix material, you can use a higher percentage of RAP,” says Steins. “In the last couple of years, the Wirtgen Group has been starting to think about different production systems for roadbuilding. We call warm recycling one of them, which involves the end-to-end process. We look as a Group at the milling process via the Wirtgen cold milling machines; then we have Kleemann for crushing and screening; then we look to create the right asphalt-mix recipe with our Benninghoven asphalt plants that give the maximum economic and sustainable output for our customer, then bring it back to the road [for Vögele paving and Hamm compaction].”
Mac Nelly adds: “Some plant owners have tended to produce asphalt at the hottest temperature possible as they think it gives them the highest quality product. They want to see the steam over the asphalt. Around 95% of asphalt-plant operations in Germany have traditionally used lignite coal dust as a fuel, and energy has been really cheap. Plant owners have started rethinking and saying, ‘Okay, fuel now costs a lot of money, and maybe 150˚C will be enough temperature as the final product quality is much better as the [asphalt’s] physical properties don’t like high temperatures’.”
“We have recycled asphalt material that can be processed at 160˚C, yet we still see some virgin material being overheated because it is sometimes not believed that temperatures around 160˚C can achieve a high-quality product,” says Steins. “We have enough examples we can show. You don’t have to change your asphalt plant’s fuel if you manage the heating of your virgin and recycled material more efficiently. This will give you significant energy cost savings and reduce your CO2 emissions.”
Steins says modern technology will likely quicken the switch to lower-
temperature virgin and recycled material asphalt production. “In the past, some very experienced technicians would turn every knob on the asphalt plant and knew what to do. Where asphalt plants are going is having a control system that will achieve consistent product output and lower energy use. It is a required shift as getting people with decades of experience to run asphalt plants is hard.”
He continues: “Our plant-servicing business is just properly starting. What moved it on was the covid pandemic, as we couldn’t send people to customer sites, so we made failure identifications through remote function. We also did some remote commissioning of plants. Developing our plant control system, including a new control setup for our burners, has made much remote servicing possible. We can do some remote burner maintenance. Customers have seen
the positive results they are getting, which gives them the confidence to invest further in plant servicing.”
Steins believes preventative maintenance solutions are perfect for the needs of Benninghoven’s 24/7 modern customers. “We used to have customers doing roadbuilding, say, March until October, then have a long winter break, during which they do their plant maintenance. With changing weather patterns, there are no longer two-thirds of the year business and one-third of the year maintenance businesses. There are more and more all-year-round businesses in more need of preventative maintenance.”
Steins says the fact that customers in many countries are finding it increasingly difficult to get a permit to operate a new asphalt-plant site is also playing a big part in a market shift to more sustainable and more efficient asphalt-plant production, often through the retrofitting of new technologies on existing plant models. “It is much easier to get a permit for an asphalt-plant retrofit where a major part of the plant, like the burner or complete drying system, is exchanged for our latest modular solutions. A customer’s capital expenditure is also less. We have the corresponding retrofitting solutions, and we are seeing a lot of interesting projects.”
Returning to the makeup of today’s global asphalt-plant market, Steins notes that it is extremely difficult to calculate exactly how many plants are operated worldwide. “There are a lot of very small plants using very simple technology. In the more traditional markets, there is a lot of larger plant

consolidation, with those plants involved in more complex applications.”
Asked which Benninghoven asphalt plants are the most popular with customers, Steins responds: "We have seen great interest in the ECO series in markets like the Middle East and Eastern Europe. It is not needed to do much warm-mix asphalt production. It is a standard plant with high economic efficiency; a reliable investment. The RPP (Recycling Priority Plant) series is popular in Europe for asphalt-recycling applications regarding maximum recycling rates in asphalt production with minimum emissions. The leading recycling technology allows plant owners to produce asphaltic mixtures from 100 % reclaimed asphalt. Thus, the RPPs also stand for a reduction of the CO2 footprint.”
During our three-way Microsoft Teams call, Mac Nelly displays a series of diagrams and charts. One diagram shows the amount of carbon dioxide emissions in a kilometre of highway production chain; another highlights the impact of RAP content levels on a plant’s carbon emissions.
“Carbon emissions occur during the extraction, crushing and screening of the virgin materials; then you have to transport it to the asphalt-mixing plant, with the creation and transporting of the bitumen used in asphalt production generating further huge carbon emissions. Then a hot- rather than warm-mix production leads to high consumption of fuels to dry the minerals, generating greater carbon emissions. Finally, you must transport the finished material to the highway to be paved and compacted, generating further carbon emissions.
“If you substitute virgin materials for 60% of RAP materials in your asphalt-production mix, with RAP already containing bitumen, you reduce 17% of your highway kilometre’s total carbon emissions. This is possible when using Benninghoven’s Recycling Priority Plant (RPP). It is a state-of-the-art plant using hot-gas generator technology that allows customers to use up to 100% of RAP material
while complying with VOC [volatile organic compound] emissions values.”
Mac Nelly says that for customers that don’t want to spend top dollar on the RPP plant due to their lower annual production requirement, Benninghoven offers a REVOC retrofit solution, a patented innovation first presented at the bauma Munich exhibition (24-30 October 2022). Benninghoven REVOC supplements existing asphaltmixing plants with one or more recycling systems, significantly reducing total carbon concentrations (VOC) in the exhaust gas and adding up to 60% recycled material. Specified limits are not exceeded. In Germany, for example, the levels remain below the limit the TA-Luft regulation requires.
Steins says Benninghoven’s discussions with existing and potentially new asphaltplant customers have increasingly focused on where the company is going on powering its plants with CO2-neutral alternative fuels. “Roadbuilding companies with integrated asphalt-plant production see asphalt plants as offering a big bang for their buck around carbon-emission reductions alongside switching their vehicle fleets to electric and, in the longer term, hydrogen internal combustion engine or fuel cell power.”
Mac Nelly says: “Customers use oil and lignite dust to power asphalt plants, especially
in Germany, but its availability will decrease due to the emphasis on greener production. Natural gas and LPG [Liquefied Petroleum Gas] and LNG [Liquefied Natural Gas] could be fuels for the near future as a bridge technology. We can halve carbon emissions with natural gas, but it’s still present.”
Mac Nelly explains that while some biofuels, like BtL [Biomass to Liquid] and HVO [Hydrotreated Vegetable Oil], are classified as CO2-free in current legislation, making them a potentially attractive future asphalt-production fuel, others are not. “If you produce asphalt with oil and lignite dust, you generate around 28kg of carbon dioxide per tonne of asphalt. With [a biofuel like] wood dust, you generate 27kg of carbon dioxide per tonne of asphalt – nearly the same. With natural gas, you generate 15kg of carbon dioxide per tonne.
“Possibly in the near future, green hydrogen will be one of the future fuels. Will it be the only one? No, I don’t think so. But it will play a very important part. This is why we are doing a lot of research and development work around green power for asphalt-mixing plants. In addition to the fuels of the future, the focus will be on direct energy savings – all the way to locally emission-free.”
Steins adds: “We need to give our customers a [asphalt] drying system which can use all future fuels we and, potentially, they can think of. If a customer has an alternative fuel they would like to use, we can test it at our headquarters and let them know if you can burn it with our plants.” Steins says Benninghoven is the only asphalt-plant manufacturer offering in-house fuel testing. “We don’t have to test different fuels at customer operating sites,” he stresses.
Mac Nelly and Steins explain that Benninghoven’s solutions development includes customers being ‘development partners’ using Benninghoven prototypes and existing technologies on their job sites. “We can bring this to developing countries. For example, we have a project with eight or more old asphalt plants generating high energy costs; it’s a big issue. By installing our new burner and burner control system on these plants, they can burn up to three different fuels simultaneously, reducing their costs,” says Steins.
Commenting on how easy fuel-use change-ups can benefit customers closer to home, Steins continues: “In Germany, an asphalt-plant customer may have a gas contract that limits them to a certain gas usage amount per day, with anything over that permitted usage, triggering an exponential cost increase. Using our system, you can play around, saying, ‘Ok, today I will run six hours on natural gas and two hours on oil and lignite dust.’ With the rising energy prices, a German customer ran their plant on gas for an extra two hours a day, costing them €80,000.”
“In the future, it is conceivable having burner systems that can use 100% green hydrogen, which will also be able to use other fuels via a burner control system,” Mac Nelly concludes. AB
