New role for giant recycling line?

CONSIDERABLE interest is swirling around the future of the Krones recycling plant at Mpact Polymers in Wadeville. Set up in 2016 with high expectations, the R350-million-plus venture on a 20 000m² site in Atom Street, had all the approvals to produce food-grade rPET but has been shut down since early 2020. Attempts to auction off the equipment – which includes an integrated system with the big Krones recycling line, Piovan decontamination plant and infrared sorting line as well as stateof-the-art ancillary equipment – yielded little result. The situation has presented a large problem for Mpact as well as the IDC, which provided much of the finance for the venture and also owns a 20% stake. As they say, if you owe the bank a million, you have a problem; if you owe the bank a R100-million, the bank has a problem (a scenario which has become all too familiar in recent times). One of the solutions being put forward (a solution has to be found otherwise the partners are going to be hemorrhaging more and more capital) is that the line be used for polyolefin recycling. At the outset it was estimated that the plant could process about 29 000 tons of PET a year and produce about 21 000 tons of food-grade rPET from that, in other words a substantial quantity of material. If switched to PE and PP processing, the line could make a massive difference to the plastic recycling situation in Gauteng, especially the public impression of that. Interested? Mpact management and partners are mulling over options and are expected to make decisions in June. The undertaking is huge and complex, with possibly the biggest challenge being that of selling the recycled material back into the market. But something has to happen. Recycling is only for those who are ‘born to recycle’ (as one of my favourite recyclers says) and there are people who have triumphed in this sector and who provide quality and consistent recycled material, and people who can manage large groups of employees. The project either has to be successful or there’s going to be a big financial hole. It’s going to be interesting.

… IF YOU HAVE SOMETHING TO SAY Look at the bright side: if you have some gem of wisdom to impart, please write to us at tessa@summitpub.co.za

DESIGN Plastics for Life – innovative & useful Eco-designers – creating a new story for plastics ON THE COVER: At a time when protecting the environment is no longer simply a topic of discussion but has become a grassroots movement, many designers are focusing their efforts fully on the environmental impact of their creations. The idea today is to create differently: optimal use of resources, recyclability of products, integration of recycled materials, upcycling and eco-design is becoming second nature in all areas of industry. Ikea, for example, has added the Order chair to its catalogue. The chair is made from recycled PET and sustainably-grown wood ﬁbres. See page 30 more

COMMENT New Breed – It’s welcome to Luvuyo Sineke of New Breed Holdings, who has set up his own injection moulding business in Port Elizabeth. Luvuyo has been involved in the industry for over 20 years, but now he’s taking the ultimate step of going on his own and becoming an employer. Watching the business landscape in South Africa is fascinating and we sincerely hope we will be able to report about more start-ups like this. See article page 11

Convertors

showing a lot of resilience Trip around region suggests many are weathering storm well

F IT weren’t for mobile communication technology, the Covid lockdown internationally would be proving even more challenging.

In South Africa people in the industry have been used to meeting and chatting with customers and others in their market niches, and not being able to do so has been difﬁcult. So it was a relief to be able to get around the region a bit more of late. A recent trip across the Eastern Cape and KZN proved enlightening in this respect. Following Covid protocols is not difﬁcult, if anything, masks and hand sanitizing and social distancing has improved the health of most people. What I found was convertors and suppliers and recyclers who are getting on with the job at hand and coming to terms with the new realities in the market and life in a robust way. Obviously it’s likely that I would visit companies who are more successful and, as you may observe in articles in this issue, about the only difference is that you tend to see fewer people at factories – which I think is a result of changed behaviour rather than retrenchments, as these manufacturers have needed all the good people than can get.

THIS ISSUE

pages 36-43). These groups, all of which are run by women (does that tell you anything at all?), are making big strides in the environmental area and involving people across the board – it’s impressive. Not a good time for a strike MANY of you will be chafing around the collar at the thought of union negotiations resuming and NUMSA amplified that effect by announcing they were going to picket outside plastic converting businesses around the country on some days in early June. The union’s demands include one for a 15% increase, so it’s going to be challenging and it is undesirable for this to spill into open violence, which it did previously. Perhaps we should reflect on the 2018 scenario when, corroborated by many convertors around the region, the vast majority of employees did not indicate a willingness to strike. Only violence and threats forced them out. It’s going to be a big test for most convertors and, from our vantage point; the biggest challenge is whether you have staff loyalty on your side. This is not an easy state to achieve (you will almost certainly need an HR manager or consultant), but it could prove difficult without that.

Section 18 EPR is here...

6 JUNE / JULY 2021

Existing producers to register no later than 5 November 2021 AS A pro-active response to the growing national concern around waste and its impact on society and the environment, South Africa recently published the Section 18 Regulations to the National Environmental Management: Waste Act on 5 November 2020, which refers to the Extended Producer Responsibility (EPR) aspect of the National Environmental Management Waste Act (NEMWA). The regulations came into effect on 5 May. This new legislation makes EPR mandatory for all producers and importers of packaging. It changes how producers, brand owners, retailers and importers design, make, sell and keep their products in the recycling loop as far as is practicably possible. It is now compulsory for producers to belong to a Producer Recovery Organisation or to form their own independent EPR scheme if they choose not to join a PRO to demonstrate your EPR.

Boost for recycling as bottle labelling trial signals success A GROUND-BREAKING trial that renders plastic bottles with self-adhesive labels fully recyclable promises positive spin-offs for the environment and plastic producers who have until November to comply with Section 18 of the National Environmental Management Waste Act. Until now, PET plastic bottles with

adhesive labels have hampered South African recycling processes, because the glue from the labelling has discoloured the recyclate. This has meant that discoloured recycled PET (rPET) from those bottles could not be repurposed into high-quality, clear plastic beverage bottles, but only be used to produce a limited range of products. Extrupet, PETCO, UPM Raflatac & Java Print partner in trial Post-consumer PET bottle recycler Extrupet trialled the new wash-off label adhesive in April in conjunction with PETCO – the national industry organisation supporting PET plastic bottle

recycling and collections. Self-adhesive label manufacturer UPM Raflatac and label printers Java Print partook in the trial with bottler Oasis Water. “Lab results following the trial have shown a more than satisfactory result,” said Extrupet joint managing director Chandru Wadhwani, adding that the new wash-off label adhesive used in the trial easily washed off the PET flakes created as the plastic bottles underwent recycling. “The chemical composition of the new wash-off label adhesive makes it easier to remove during recycling, and the glue retention on the label has met our recycling standards requirements,” he said.

ECO-LABELLING: Yvonne Griesel and Gerrie Swanepoel of Oasis Water take a closer look at the new eco-friendly wash-off labelling trialled on 10 000 of their bottles recently

are you ready?

reporting against the gazetted targets starts in Jan 2022. For more information or guidance in this process, contact the relevant PROs directly via their websites:

Wadhwani added that plastic producers would benefit from the new technology as it would help them comply with new government legislation on Extended Producer Responsibility (EPR). “While self-adhesive labels are not the preferred choice for ideal design of a PET bottle pack – a polyolefin wrap-around label with minimal or no glue is preferred – the new wash-off adhesive label is a preferred option when a brand owner absolutely has to use a self-adhesive label,” he said. “We’re not promoting the use of selfadhesive labels, but if you have to use one, make sure it’s eco-friendly.” Wadhwani said that as long as a label was made from polyolefin, it could be recycled. “Once the label is separated from the bottle, it is melted together with the glue, and used to manufacture products such as outdoor furniture, pallets and school desks,” he explained.

• PETCO: www.petco.co.za • Polyco: www.polyco.co.za • PVC: www.savinyls.co.za • Polystyrene: www.polystyrenesa.co.za Changed chemical composition of adhesive makes it better for recycling UPM Raflatac packaging solutions manager, Trevor Isaacs, called the trial a milestone, saying: “We successfully changed the chemical composition of the adhesive, making it easier to wash off and remove the label during recycling, with no residual adhesive.” “It’s been fantastic to be part of this trial. We’re really excited about taking the product to scale and hope that suppliers, manufacturers and producers get on board quickly so that sustainable labels are soon the norm,” Groves said. 10 000 bottles with new label tested Extrupet extensively tested 10 000 Oasis Water bottles that featured the new labelling as part of the trial. “We welcome the new Section 18 requirements and happy to say we are compliant,” said Oasis Water director Naas du Preez.

Latest force majeure also beyond Safripol’s control UNDER-PRESSURE convertors will not have been impressed by the latest force majeure declaration by Safripol which, as in the two disruptions over the recent summer, was again due to factors beyond its control. Wet ethylene received from its supplier, Sasol, resulted in the delay of the restart of its HDPE plant in Sasolburg. The line was stopped in May for routine maintenance. Safripol advised customers around the country and region in a regular communique, and informed them it would only be able to recommission the line once in-spec ethylene was received. That was on 31 May and the expectation was that the delay would be a few days, but that was not certain. Co-polymer and random co-polymer supply was most affected. This comes on the back of massive interruptions in polymer supply internationally, which has seen the terms ‘allocation’ and ‘quotas’ used more than ever before. The sheer frequency of the interruptions appears to have been at least partly the result of plant problems encountered during restarts after the Covid induced slowdown. The spotlight has been turned on the material suppliers and importers, who have regularly over the years been able to supply when the local manufacturers have not, but although the market has began to stabilize, the importers have in many cases not been able to fill the shortfalls. Perhaps only the smartest convertors will be unaffected, but holding full material stores at plants is now more of a rarity, not least because it involves the tieing up of too much capital.

Second venture by Ebor group

as Ebor East London starts

8 JUNE / JULY 2021

Major auto component plant starts up in IDZ EBOR East London, the second manufacturing unit in the Ebor group following the establishment of Ebor Automotive Systems in Port Elizabeth in 2014, has gone into operation at the East London IDZ. A major venture following the success of the group’s first venture in PE, Ebor EL has been set up specifically to supply first-tier automotive manufacturers, in this case to supply Mercedes in East London. Following on the example of Ebor Automotive Systems, Ebor EL is using Engel injection machines, with all 10 of the machines installed so far being equipped with robots. Partners in the venture include Don Searle and Possey Mina of Aeteus (a venture capital business) and High Street Capital of Johannesburg. The introduction of the new business is

testament to the foresight of both the latter partners as well as the Ebor management team, specifically Wesley Strydom (former production manager who is now group MD) and Andy Dealtry. Strydom and Dealtry had been running Visteon in PE, a venture by Ford group but which had elected to exit the sector and shut the Port Elizabeth plant in 2014. They along with Aeteus and High Street later that year put together a ‘rescue’ plan which purchased the production equipment of Visteon SA and restarted the plant, in the process saving most of the jobs that would otherwise have been lost. Ebor Automotive has since expanded and now employs about 140 people in PE. Successful operation of the first plant – and specifically on-time delivery to the very exacting specs required – saw Ebor’s relationship with the automotive www.ebor.co.za

OEMs grow. “That at least got us in the queue to supply the automotive groups,” said Searle, who even though in his 70s now continues to invest in plastic converting businesses, an example of commitment that appears to be at the core of the Ebor philosophy. The same partners mentioned above are now involved with Ebor East London. The plant’s layout is designed to optimize production, which is one of the advantages of starting from scratch. The experience of the managing partners, built on years in the manufacturing sector, has been put to very effective use in this respect. The 4000m² property in the Industrial Development Zone is leased from the IDZ authority. The group operates a staff trust through which all employees are shareholders in the company.

New Breed Holdings starts up NEW Breed Holdings, an injection moulding business, has recently opened for business in Port Elizabeth. New Breed is a venture by Luvuyo Sineke, who started out at Transnet, then spent 15 years at Venture SA in Uitenhage (where he learned first about injection moulding), was at Continental Tyres in PE and finally at ISG in East London before

taking the decision to go on his own. According to Luvuyo, who has a National Diploma in Cost & Management Accounting, New Breed “aims to be at the forefront of localization and transformation in South Africa in the automotive and nonautomotive sectors.” He has been involved in injection moulding since 2018.

“We have high speed spindles that allow us to run very small diameter cutters and up to 50 000rpm, resulting in better finishes and faster turnaround times, We are capable of machining moulds with plate sizes of 1 000mm x 500mm. In conjunction with our mould design department, PMM find ways to machine the majority of its moulds without sparking. This relates to quick turnaround time in mould manufacturing,” exsplain Steenekamp. PMM also offer a turnkey solution in terms of blow moulding for HDPE, LDPE and PVC and all the moulds can be designed and manufactured in-house. PMM can blow mould up to a 2.5-litre sized product and have three double station with single head machines, one double station with double head machine and one single station with single head machine. The company also has visi strip capability. The company services the mining, electrical, building, stationary and medical industry, to name a few. “Cabletech Marketing strives to provide service on demand as well as exceptional products for our customers,” says Tiaan Visser, Cabletech Marketing sales manager.

Recycler Afri Waste closes doors AFRI Waste Group, which set up for recycling at Fort Jackson in 2016 and had considerable potential to both reenergise the plastic recycling sector in the Eastern Cape region, has closed. With what appeared to be a solid business plan, Ikusasa inspired hope and there was potential for job creation too. Some customers felt Afri Waste wanted to sell its materials at higher rates than has been standard in the recycled market in SA. Most of the equipment, which included a heavy-duty Enma recycling extruder ex-China, has been auctioned off. The wash plant (the only one in the region up till now) has yet to find a buyer, however.

Kibo, IGES to develop portfolio of waste-toenergy projects in SA THE share price of JSE- and Aimlisted Kibo Energy rose by more than 7% and 3% on the JSE and LSE, respectively, on 18 May, after the company announced that it had entered into an agreement with South Africa-based Industrial Green Solutions (IGES) to jointly develop a series of waste-to-energy projects in South Africa. The companies have established Newco, in which Kibo will hold a 65% interest and IGES the balance, to deliver the projects. The parties have set an initial target of generating more than 50MW of electricity for sale to industrial users. The projects will convert plastic waste, to be provided by waste disposal operators, into syngas using a pyrolysis plant. The syngas will be stored on site and fed into gas engines to generate electrical power. Kibo said that the first project would be developed in four phases of 2MW each, with the first 2MW phase to be completed within 16 months.

New Hision CNC vertical machining centres meet growing in-house mould manufacturing demand Cabletech recently installed two new Hision CNC vertical machining centres

at customers to assist with the growing in-house mould manufacturing demand. Moret Mining was established in 1990 by Roelf and Jodi van Blerk and has since grown exponentially as one of South Africa’s leading manufacturers of conveyors for bulk handling products, as well as for the overseas market. Every product is designed in-house and is manufactured in their Johannesburg factory. Moret passionately believes that with dedicated excellence and commitment to value-added service, great success can be achieved and that is why they use Cabletech Marketing as a machine tool supplier. As no stranger to the Haitian injection moulding machinery quality and repeatability, the Hision VMC 1000II Vertical Machining Centre became the obvious choice. The machine features large travel sizes for such a compact machine – 1 000mm on X-axis, 600mm on Y, and 600mm on Z-axis – and has 750mm daylight between spindle and table. Böck industries, however, opted for the smaller VMC 850II version in the VMC II range. Like the bigger brother,

the machine also features the same standards but with a slightly smaller machine bed and travel. Dieter Böck, owner of Böck industries and avid aircraft builder and pilot, felt the need to upgrade his toolroom and after months of deliberation decided that the Hision VMC 850II would be an excellent addition. Accuracy and detail were key and the Hision is able to deliver those requirements Dieter started Böck industries with his father Ludwig in 1975 when they started manufacturing small household items like key rings and bird feeders. He now works with his son Karl in this multi-generation business. They manufacture household items in the pet, automotive, aviation and floral industries. Their large variety of machines allows them to produce many different products – from number plate holders to electric fence bobbins and much more.

VinylLoop gets the go-ahead as new vinyls packaging PRO

Driving a circular economy for the vinyls packaging industry

70% of local PVC market goes into non-packaging products used in long-term applications MEMBERS of the Southern African Vinyls Association (SAVA) voted unanimously in favour of forming a separate Producer Recovery Organisation (PRO) within the association, whose specific focus will be to manage the collection and recycling of post-consumer and post-industrial vinyl packaging waste.

14 JUNE / JULY 2021

Why a separate PRO for vinyl packaging? Explaining the rationale for forming a new PRO for the vinyls packaging industry, Monique Holtzhausen, CEO of SAVA, explains that 70% of the local PVC market goes into non-packaging products that are used in longterm applications such as pipes, window frames and doors, flooring, cables, ceilings or in the healthcare industry. “Some of these products last in excess of 150 years. It is therefore not the responsibility of these SAVA members to fund the collection and recycling activities for vinyl packaging that occupies less than 2% of the overall market. The decision was therefore taken to form VinylLoop for packaging members, Monique funded by packaging Holtzhausen, members and headed up CEO of SAVA, by Adri Spangenberg.” and Adri

Spangenberg, who will head up VinylLoop

Size of the PVC packaging market in South Africa South Africa manufactures roughly about 12 000 tons of vinyl packaging per month that goes into bottles, thermoformed punnets, pharmaceutical blister packs,

cling film etc. This represents less than 2% of the total PVC market in the country. “Although vinyl products are readily recycled in South Africa, there has never been a formal collection and recycling programme for post-consumer and postindustrial vinyl packaging waste due to the fact that the volumes in this market were considered to be too small to justify the costs of collection and transport,” Monique explains. “As part of our strategy for dealing with packaging waste submitted to Government’s Section 18 Industry Waste Management Plan, SAVA is currently developing a unique collection model for household packaging waste that bears the Number 3 polymer identification code. This plan includes working closely with municipalities and the entire value chain.” VinylLoop operations and responsibilities explained VinylLoop operates under the SAVA banner, but will be registered as a separate Non-Profit Company (NPC), with its own board, bank account, membership forms and invoicing system in order to facilitate the bi-annual audits by Government and avoid administrative confusion. “Companies who sign up to become members of VinylLoop will automatically also become members of SAVA and will therefore reap the benefits of belonging to both associations,” Adri explains. However, where normal SAVA members pay an annual membership fee, VinylLoop members will be required to pay a monthly levy based on the declared amount of vinyl packaging (in tonnages) they produce over the next six months. Initially this amount will be R100 per ton until 5 November 2021, after which members will be informed of an adjusted membership levy. These funds

will be used to set up the necessary infrastructure to ensure VinylLoop members reach the targets that have been set by Government for the collection and recycling of all PVC (vinyl) packaging that is used in the market over the next five years. As the PRO representing the vinyl packaging industry, it will be VinylLoop’s duty to: ensure the EPR scheme is audited by Government; collect and submit data to the SA Waste Information system (including how much PVC vinyl packaging is collected and how much is successfully recycled); put buyers and sellers of vinyl packaging waste in touch with each other; keep records of identified products; work with municipalities to develop the necessary collection and recycling infrastructure; integrate informal waste collection; and establish secondary markets for recycled vinyl packaging waste.

• •

• • • • •

The new EPR regulations came into effect on 5 May 2021 and all the packaging streams in South Africa now have six months to comply. By 5 November 2021 it will be compulsory for all converters, manufacturers, importers, brand owners and retailers to either belong to a PRO or to have formed their own independent EPR scheme.

Twist in the Taili … not quite, CAD Plastics is in fact very happy with its range of Taili injection moulding machines, set up to require minimal operator intervention, and the Pinetown convertor now operates 13 of the machines

There’s no

twist in the Taili,

Darren Bezuidenhout, toolroom manager at CAD, with Shane Collier of WD Hearn, the machine technical applications engineer

new machines prove popular Success at CAD Plastics boosts machine brand By now skepticism about Chinese injection moulding machine has faded to a distant murmur, although it wasn’t so at first. In the 1980s and 90s most machines from the Far East were treated with much doubt, but then the Taiwanese and after them the Chinese began to supply machines with steadily improving technical abilities and reliability, to the point where they even began to rival the European marques. But each new brand from the Far East, and there have been many, is almost by regulation treated with doubt on first arrival. And so it has been for Taili, a brand of machines introduced into South Africa by WD Hearn in 2017. Like virtually all the ex-China machines now available in South Africa, the company (full name Ningbo Tailike Plastic Machinery Co Ltd) does its own metal casting and manufactures all its metal components at its plant in Ningbo in China, possibly by now one of the top global centres for injection moulding technology development. There it operates five workshops. It comes as no surprise that it is first focussing on smaller machine production, with the virtual certainty – as has been the case with the many other Chinesemade machines in SA – that their technology will expand and machine performance will irrevocably improve. That is what the guys over there do: by contrast the only SA-made machines in our industry which have achieved any international success are the bag-makers from Technimac and before that Adron. By contrast, there are hundreds of injection moulding machine brands from China, not to mention other machinery, and all arrive with intensely focussed Chinese personnel who solely committed to machine performance improval.

IMM has been CAD Plastics of Durban, and the need was obvious: They needed smaller machines to produce its range of small components. CAD owner for 27 years, Malcolm Buchanan put one of the machines in, based on an already great working relationship with CNC supplier WD Hearn, then introducing TAILI. He elected to try one of the machines from the Taili TLE range … and it’s been virtually non-stop Taili since. CAD now operates 13 of the machines, ranging from 50 to 220 tons clamp force. Buchanan played quite a big part in the Taili roll-out: he suggested that the mould temperature control cards be built into the electrical panel and can control up to 64 zones by the EST control panel (which is possible with Taili’s full range) also protective covers be placed on the hydraulic components. All the TLE range machines at CAD are standard with higher screw speeds creating faster cycle times. Other proprietary features have been introduced since too, including: • Standard bi-metallic screw and slotted plattens; • Double core pulling and twin air blow; • EST controller system to handle higher screw speeds with high speed data buss to servo drive; • Servo drive software implemented into the system • Visible Machine power usage for Kw/ hour on the control. According to Myles Crosthwaite of WD Hearn, the success at CAD has been a catalyst that has seen other moulders in KZN opt for the Taili solution, boosting conﬁdence in Taili and the process has gained further momentum since Brett Shelley, a leading machine control specialist, joined WD Hearn. www.nb-taili.com

Multi-purpose CNC machine gives it new options GPS Plastics in Durban has installed its own toolroom, giving the KZN injection moulding business considerably more control over its mould manufacturing requirements and closing the loop for it, so to speak. GPS manufactures a range of technical items as well as domestic appliances and managing director Kevin Govender, a man who’s not scared of a technical challenge, has steadily expanded the range of services it offers in the decade-plus since the company was started in 2006. One of the biggest steps to date was developing its own assembly operation and a number of the products it manufacturers are now fully assembled on site and tested as well as packaged in client brand boxes. “We are always coming up with new product ideas,” said Govender. “Installing our own toolroom gives us an advantage in the market. We now have a one-stop-shop. Obviously it gives us far more control over our tools, and it also enables us to amortize the tools more easily as we now exactly what our costs are,” he added. The main new item in the onsite toolroom is an Akira Seiki KM 150 machining centre, supplied by nearby MJH Machine Tools. This is a multi-purpose CNC machine which can be used for high-precision tool and die making as well as general engineering work. Govender and his team have been building towards the launch of GPS’s toolroom for a number of years already and, apart from the Akira system, have sourced all the necessary cutting systems to build small to medium sized moulds, with a number of the items being bought on auction. Included in the toolroom are a surface grinder, milling machines and lathes and various other peripherals needed for a standard toolroom as it sets out on this new journey. Designer/toolmaker Kevin Watson (ex-Jhb) has been appointed to run the facility. “Some of the moulds are owned by customers, but our goal is to amortize the tool costs as quickly as possible, and we believe this makes us more competitive,” added Govender.

“Polystyrene and other plastics are often the most visible form of plastic pollution in our rivers and waterways due to the fact that they are lightweight and ﬂoat. The fact that litter that possibly could have ended up in our oceans, have been put to good use to create a new ﬂoating base for HOPE, makes this whole initiative so much more impactful and poignant,” remarks Du Preez. 400 litres of recycled polystyrene beads (10kg) were collected from the Kraaifontein MRF and used to create the base that measures 2.4m x 2.4m and is

New use for ﬁreﬁghting tank – Niko White and the Principle Plastics production team in Port Elizabeth have devised a system to circulate water from the large water tank to cool their injection moulds; (right) White with one of the resulting products, an exterior part for one of the new locally produced models currently in production

Principle chills out with new solution Saves both water and energy costs PRINCIPLE Plastics in Port Elizabeth has come up with a novel cooling solution for its fleet of injection moulding machines – by circulating water from its firefighting water storage tanks via a Plate Heat Exchanger system, to keep the moulding machines oil at optimum temperatures. The solution saves both water and energy costs. Principle is running a range of mainly polyolefin materials to manufacture automotive components with the need to tightly control the moulding machines oil temperatures at around 43°C (+- 1°C) and opted to not use a standard solution (the original cooling towers used in plastic converting tended to lose considerable quantities 22

of water to evaporation, amounting to around 400 litres per hour in peak summer conditions – this is now reduced to zero). The Markman Industrial -based business had been obligated to install two x 400 000-litre water tanks to meet firefighting requirements and the solution devised by Principle MD, Niko White, and the Principle team involved piping the water from the tank to a central pump and then circulating the water to the machines and back to the tanks. In winter the temperature in the storage tanks could drop to around 6°C, while in summer it can get up to 30°C. As such, each machine is fitted with a self-regulating 24V valve

that opens and closes automatically according to the requirements to maintain oil temps at the optimal 43°C. White, who is closely involved in devising control technology for production on an on-going basis, believes the advantage of the system is that it makes logical use of the stored water, which would otherwise be a ﬁxed cost only used in the event of ﬁre. “So, we are not using the water at all as it remains in a closed water tight system. We are merely using the ‘cold’ in the water to our advantage. The tanks cool down naturally over the weekends and are ready to go come Monday mornings for startup! www.principleplastics.co.za

Mould Base moves into own warehouse Mould Base, the injection moulding machine and accessory supplier, has moved into its own warehouse in Mount Edgecomb, KZN. Located close to the N2, the 1 500m² space is a secure and clean storage area where Dave Moore and his team are keeping a few Yizumi machines in stock, along with spares and other equipment. Part of the logic is that since it’s taking far longer to ship machines out from the Far East (doubled from three months lead time prior to Covid to over six months now), holding machines in stock is the best alternative. The machines being stored have proved popular and delivery to anywhere around the country can be done in days.

ROEDIGER Agencies cc, specialising in troubleshooting and research of polymers and related applications, recently moved to new and larger premises at the end of April and invested in some important new equipment. The laboratory’s core business is testing the chemical and physical properties of polymers. It is also one of the few labs in SA that can test that a polymer is food contact certified. New premises The laboratory’s new premises are at Unit 4, 6 Santhagen Road, Devon Valley outside Stellenbosch, and at 350m2 are almost twice the size of their previous premises at the University of Stellenbosch. Owner and MD, Dr Andy Roediger (a polymer scientist experienced in various fields of polymeric applications) says that the new address has much easier access and plenty of parking. Roediger Agencies has a wide range

of advanced analytical, thermal and mechanical equipment. This allows extensive and complete investigation of problematic or researched materials, and enables the laboratory to blend practical and technical with relevant data. The methods, findings, conclusions and recommendations of each study are reported in full.

Testing polymer pipes The need for the laboratory’s services has also increased and has seen a 15% growth over the previous year. This is in large part due to the fact that the laboratory is now also able to test pipes. Andy says that the lab started testing polymer pipes last year (mostly PVC and high density) with all the initial auditing accreditation needed to do so, eg. SATAS, and an initial audit by an accredited auditor. Tests which Roediger Agencies can carry out on pipes include checking pressurisation, tensile properties, Vicat

The majority of Lee’s customers are corporates, schools and local brands; some of her customers include large corporates like Coca Cola South Africa and Landrover, as well as initiatives such as PIKITUP, the official integrated waste management service provider to the City of Johannesburg. Waste rubber for flipflops The Flop Factory is Lee’s core business and her mission from the onset was to create a zero waste factory. 30% recycled rubber content is used to manufacture her trademark RAW sole range, offering the market a durable eco-friendly fully customizable flip flop range. GRRiTT, her flipflop brand, goes a step further – using waste rubber from discarded tyres to manufacture the tread. One tyre from a normal car makes 10 GRRiTT flipflop treads. The flipflops are extremely durable and come with a two-year guarantee, and “if it breaks, we replace it – unless your dog chewed it,” says Lee. Taking the sustainability theme even further, Lee collaborates with a sister company, project WAYSTD, and package every pair of GRRiTT flipflops sold in a co-branded 100% recycled PET carry bag. Since the Covid-19 pandemic a project WAYSTD facemask is also included. Two 2-litre plastic bottles are recycled to make these products. “We go to great efforts to communicate to our clients that their purchase of a pair of GRR!TTs is a catalyst for change”, says Lee.

Pac-Rite commissions

high-speed laminator

New line gives KZN flexibles manufacturer several more options

28 JUNE / JULY 2021

PAC-RITE of KZN has further extended its product range with the commissioning recently of a new laminator. This comes on the back of the 2018 installation of a co-ex film extrusion line at the Westmead company, which gave PacRite the ability to produce all of its own films to exact spec, print on them and now laminate too. The line, from TCE-Converting of Turkey, is a state-of-the-art piece of equipment from a manufacturer that up till recently was not well-known in this part of the world. Lamination is solventless, which was a factor in Pac-Rite’s decision to buy the line as it allows for cleaner operation and reduced environmental effect. According to Pac-Rite CEO Brian McCleary, the TCE unit gives it the ability to laminate a variety of substrates

onto poly as well as either clear or foiled BOPP. Two layers are joined in the laminator, at eye-watering speeds of up to 400m a minute, and then there is also the option to run the joined structure through again to add a third layer. That is not often a requirement, but it’s a plus for Pac-Rite to have the ability. The R6-million capex project included a ‘Kinetic Easy’ 1300 slitter-rewinder from the same manufacturer, Turkey’s TCE, which is represented locally by Burns Machinery. McCleary visited the TCE-Converting plant in Konya, an ancient city in central Turkey dating back to the 12th century, to assess the quality of the build and came away feeling confident. The Kinetic slitter-rewinder is anything but easy, running at up to 400m/min like the laminator, and yet able to

maintain extremely precise registration. A just-completed run of reels showed impressively consistent winding. “We are happy to have advanced into specialised films,” said McCleary, “and moving into laminating is really a natural progression for us that are also in response to customer demand.” It’s worth noting that Pac-Rite (full name Pac-Rite Innovated Packaging Solutions), established in 1994, started out as a general packaging supply business before it got involved in manufacturing, producing its own films, from which point it has progressively made investments in equipment to the point where it is now close to being on a par – or even on a par – with SA’s top flexible packaging manufacturers. www.pacrite.co.za The production team in the new Pac-Rite lamination hall includes Sixtus Magwasa, Shoheb Wahab and Fortune Moluli, here with Brian McCleary

A first as Zerma opens size-reduction Test-Centre

32 JUNE / JULY 2021

Full test done to assess system performance ZERMA Africa has recently introduced a new Test-Centre at its warehouse in Barbeque Downs near Kyalami in Johannesburg. In what is almost certainly a first for the SA plastics industry, Jeff Cawcutt and his team have installed a range of granulators and shredders with the aim of performing trials with material provided by the customer. According to Jeff Cawcutt of Zerma Africa, the objective of the Test-Centre is to allow potential customers to run their specific material on a Zerma machine, assess the performance of the recycling system and verify the

quality and suitability of the regrind before making an investment. “We installed several granulators and a shredder in our warehouse. Plastic converters or recyclers are welcome to send us a sample of their material, we reduce it, video the process and return the material to the customer,” said Cawcutt. The whole process is thus fully Covid compliant, or alternatively customers can inspect the machines and witness the trial first-hand. “The idea is to eliminate the unknowns and give our customers peace of mind, which has been well received,” he added.

Path Plastics celebrates twenty five years

Expanded product range through innovative product design & custom product development PATH Plastics, the Cape roto moulding business, celebrates 25 years in operation this year. Reputed to be South Africa’s leading manufacturers of plastic lockers, Path at first carved out a niche for itself in this specific area, coming up with a range of practical solutions – a range of lockers which is continually evolving and keeping up with market conditions. With just seven employees, Path Plastics started out in 1996 with the manufacture of a range of containers, bulk containers and pallets to provide quality local alternatives for the food processing industry – initially focussing on the fishing industry and other protein processing industries. Since then, it has spread its wings to include a wider range of other large-volume products used in economic sectors across the spectrum and now employs 102 people. A substantial percentage of Path’s production output goes towards custom-designed and manufactured products for exclusive clients. Path boasts its own full technical workshop which can produce and maintain very sophisticated moulds. The company

also does a significant amount of custom moulding for customers. Path has exhibited skill at absorbing and integrating Incorporated other roto businesses, two other roto not by specific intent but rather where the businesses, achieved concerned operations almost seamless encountered difficult integration trading conditions.

34 JUNE / JULY 2021

Success in a male dominated industry JOYCE Reddell, CEO of Path Plastics in Montague Gardens, is an astute businesswoman, achieving enviable success in the predominantly male dominated rotomoulding industry in South Africa. When Path Plastics launched in 1996, Joyce had no experience in the rotomoulding industry. However, she had been running her own businesses and doing well enough to help fund the launch of Path Plastics. Determined and ready to learn, Joyce’s technical knowledge of the rotomoulding process and the industry developed

swiftly as Path Plastics grew. She found she enjoyed getting to know the people working in the factory and also getting involved in all aspects of the job, from accounting to sales. Critical to the company’s success, says Joyce, are her team of employees who are experts in what they do, with the majority having been with Path for more than 10 years. “Along with my husband, and our general manager, Van Zyl Kruger, who are both industrial engineers, my employees – right down to the last trimmer – are my right-hand men and women,” says Joyce. “And Van Zyl is able to take a bird’s eye view of any challenge and pinpoint the solutions.” Joyce describes her husband,

Tim, as “the man behind the woman, supportive and always full of good ideas”. Joyce says during her 25 years in the rotomoulding industry, she has come across some prejudice because she is a female, but nothing that has made her feel unduly uncomfortable and detract from achieving the required end results. “We do what we do, well, and will continue to do so. Our small sales team are excellent at their jobs, and it helps that a lot of our products sell themselves. Our customers come back time and again,” she says. Path Plastics is following a trajectory to even better things in the future, continuing to develop new products and provide healthy competition for the industry.

Path Plastics has a solution for almost any locker application

Consolidated Based in Montague Gardens, Path at one stage operated from three separate sites. This was partly the result of the fact that roto moulding requires more space than most other plastic processing technologies, but the business has now consolidated at a new site in Link Close over the past year. The layout of the far bigger site of over

5 000m² has been managed by Kruger, who has gone into great detail to ensure that the flow through the plant, from incoming material to outgoing product, is optimized. Given that most roto products are bulky, achieving easier movement around the plant is critical. Its engineering division operates from adjacent premises, meaning that mould manufacture or mould modification as well as metal stamping and punching is accessible. Kruger was at pains to ensure that product flow was in one direction, with material supply centrally located. Path also runs its own pulverizing department for short-run material preparations as well as to reprocess production scrap. A major factor in the layout was to minimize fire risk, so the design allows for sections to be isolated in such an event. The entire plant is monitored by fire detectors and cameras. Path has also taken a hard look at its plant and opted for Italian roto technology. It now operates four state-of-the-art

machines – including ‘Old Faithful’, the first machine commissioned in 1996, built by Piet Hickley. Deciding on this course was fundamental for the company – it wrote off all 10 of the machines that came with the Polybox purchase, as they were all way below Path’s expectations for highperformance machines. Given that energy costs and relatively long cycle times are a major factor in roto moulding, selecting high-efficiency production equipment is vital to remain competitive. Own design Path operates its own in-house design team and is constantly involved in new product development. “We like working with custom products,” said Reddell, adding that quite a number of their products are seasonal, which can have the effect that some products ‘subsidise’ others. This is an important aspect in the roto sector, where ‘non-tank’ product development costs tend to be higher. www.pathplastics.co.za Celebrating Path Plastics’ 25 years – the operations managers, ensuring the company’s success.

ASSOCIATIONS

Unique recycling project gains national traction So far, 20 schools in Umlazi have joined the Separation at Source programme A UNIQUE programme aimed at upping collection and recycling rates, boosting green economy jobs and diverting waste from landﬁlls has started to roll out across South Africa. Following a successful pilot rollout in Thohoyandou and Sibasa in Limpopo in March last year, the Separation at Source programme has celebrated its launch in a second province – KwaZulu-Natal. The 13 May launch in Umlazi saw PETCO – the national industry organisation that supports polyethylene terephthalate (PET) plastic bottle recycling and collections – hand over 120 recycling bins, sponsored by SA’s leading polymer producer Safripol, to environmental group Isphepho Enviro Ambassadors. The donation, worth over R230 000, included 50 bulk bags, a 12-metre storage container, platform scale, signage and a 6-metre volume trailer. The colour-coded green (glass), yellow (plastics), blue (paper) and red (cans) bins will appear at schools, communities and businesses in and around Umlazi and will allow residents and businesses to separate out their

household waste for the ﬁrst time. This means – at least for those who partake in the project – that only waste which cannot be recycled will end up in the municipality’s landﬁlls. Isphepho (isiZulu meaning ‘tornado’) collects recyclables from the community and also facilitates clean-ups in Durban. So far, 20 schools in Umlazi have joined the Separation at Source programme, with Isphepho collecting a a minimum of 10 tons of PET plastic a month. Isphepho aims to increase the number of schools registered to more than 50 over the next year. The 35-strong ambassador group comprises mostly unemployed graduates from disciplines including IT, public administration, speech and drama, conservation and agriculture. Londi Mbuyisa, who established Isphepho in 2018, says she was inspired to do so after founding another community engagement project in 2016. The organisation is self-funded by Mbuyisa, a senior lecturer in the Department of Nature Conservation at Mangosuthu University of Technology. None of the team earns a salary. “The awareness and participation in recycling among

ASSOCIATION-.indd 36

Apart from focussing on product standards and long-term quality, SAPPMA also fulﬁlls an indispensable need for technical marketing and problem solving within its own membership and throughout the industry. This is done by providing reliable and objective design information to the market by way of consultations, conferences and technical literature. According to Ian Venter, SAPPMA’s technical manager, it is clear that these virtual quality workshops address a major need for updated technical and practical information. Moreover, delegates are eager to offer topic suggestions for future webinars, as they know where the skills gaps exist and where the difﬁculties lie.

“SAPPMA members and nonmembers alike are given the opportunity to be trained on aspects that are important to ensure long lasting effective pipe systems, thereby minimizing costly failures. Our March worship was entitled ‘Joining the dots: PE Pipes & Fitting’, related to effective jointing and welding, and our April webinar focussed on Buried Thermoplastic Pipe Behaviour. Both these subjects play a signiﬁcant role in ensuring that pipe systems perform to design assumptions and speciﬁcations as well as meet client expectations. However, substantial changes and improvements to standards and design approaches have taken place during the last two decades which need to be clearly communicated and understood,” Venter said.

Mbuyisa also plans to add value to the waste collected by using it for manufacturing construction materials such as bricks “to make affordable housing a reality for the community”. “PETCO coming on board brings Isphepho one step closer to the realisation of our dreams,” said Mbuyisa. Safripol sustainability manager, Dr Avashnee Chetty, said the company was “committed to supporting waste collection projects such as this as they are an important enabler to the circular economy.” “Separation at source initiatives ensure that valuable recyclables stay out of the environment and are recovered for use in the recycling industry. These projects also have

the potential to contribute towards improving the lives and livelihoods of the most marginalised communities,” said Chetty. Belinda Booker, PETCO collections and training project manager, said there was “a huge need to support collection and recycling activities, especially in rural areas and townships where waste management is not well serviced or a priority”. “PET plastic bottles are not trash. They are resources that can be recycled and brought back into the value chain, with local beneﬁciation,” Booker said. Partnerships at all levels of government, industry and civil society were the key to encouraging waste reduction and increasing collection and recycling, she added. PET recycling in South Africa has consistently created more than 60 000 income opportunities annually since 2018. www.petco.co.za

Plastics|SA launches ‘Fit for Purpose’ campaign THE importance of something being “Fit for Purpose” is one of the key concepts of success in our modern world today. It describes the way in which a product or service is able to meet the speciﬁc demands for which it was selected or created.

www.plasticsinfo.co.za

Despite the harsh criticism often levelled against it, plastics have time and time again proven to be the ideal material for the 21st century. For this reason, Plastics|SA has developed a brand new marketing and advertising campaign entitled “Fit for Purpose”. “During the past decade much research has gone into producing new-generation plastic products that offer performance that is far superior than any other material. It was therefore important for us to focus people’s attention on the many positive attributes of plastics and why it is the material of choice for so many modern day applications such as building and construction, education, entertainment and lifestyle, sports, healthcare, packaging, etc,” explains Anton Hanekom, executive director of Plastics|SA. According to Anton, this campaign will include printed adverts in selected media, as well as on social media and across various other digital platforms. “We are very proud of this new message that is visually appealing and impactful in its simplicity. Our on-going appeal will be to use plastics responsibly and to ensure that all plastic products are recycled once they have reached their end-of-life. In this way, many new products are created that often have a longer lifecycle than its original purpose”. “Whether preventing food waste and extending the shelf life of fresh produce, or saving a life with medical devices, a lot of research goes into using the right type of plastic for the right application. Plastics truly are ﬁt for purpose: highly functional, impressively innovative and widely trusted,” Anton concludes. Examples of a few of the advertising and awareness messages that have been developed as part of the new ‘Fit for Purpose’ campaign

SAVA also managed to grow its membership by welcoming Food Packaging System and Orchem as full members and introducing a new category for individual members. “In many respects 2020 will be remembered as a year that was painful and hard, but if you look at the number of attendees today its shows that the industry has managed to pull together and unite in a time when it was important for us to do so. We kicked off the year by adopting the theme ‘Building for the Future’, not only because vinyls are widely used in the building and construction industry, but also because we wanted to grow the local vinyls industry and along with it, SAVA’s reach to include the entire value chain. Looking back, we are proud to report that we have succeeded in meeting this objective”, said outgoing SAVA chairman, George Dimond.

An exciting future head Concluding the 2021 AGM, newly elected SAVA chairman Debbie Munford said: “We are very excited about what the future holds for SAVA. We start our work on a strong and solid footing thanks to the excellent work done by the previous Board. The Section 18 EPR legislation presents us with exciting challenges, but also an opportunity to increase our membership base and inﬂuence team members to become active and grow with SAVA. “It is clear that both the global and domestic PVC markets are facing challenging times ahead, but we are fortunate to have access to a wealth of industry expertise to help navigate us through the multitude of economic, social, political and environmental factors through our local network of members and partnership with the Global Vinyls Council and Vinyls Plus. More than ever before, it is vital to belong to an industry association such as SAVA that fosters understanding and co-operation between suppliers, manufacturers and end users to ensure the sustainable future of our industry”.

SAVA signs up another new member OMYA-Idwala South Africa has become the newest member of the South African Vinyls Association (SAVA). The company is a raw material supplier of value-added calcium carbonate and specialty PVC additives. Omya-Idwala SA was ofﬁcially launched on 1 February 2020 after Omya International AG and Idwala Industrial Holdings Ltd agreed to join forces in order to strengthen their activities in South Africa with regards to the distribution of calcium carbonate and specialty chemicals. Today, Omya-Idwala SA has ofﬁces in Johannesburg, Durban and Cape Town from where they provide their customers in the coatings, plastics, paper, inks, adhesives, chemical, homecare, glass and agricultural industries with a one-stop-shop opportunity with high-value services. According to Natasha de Lange, general manager of Omya-Idwala SA, it was important for them to join SAVA as this would allow them to remain up to date with the latest innovations and changes taking place in the local

and international vinyls industry. “We are focussed on building a strong platform for future growth in the large and rapidly developing South African market for specialty chemicals and value-added calcium Natasha de Lange, carbonate products.

people On the move Craig Lowe has been appointed chief operating officer at MCG Industries, based in Johannesburg. This comes at a challenging time for the MCG group, which is facing difficult marketing conditions on the back of the repositioning of MCG Flexibles, it’s film making business which has been moved from Jacobs in Durban to Johannesburg, as well as the loss of some key management personnel at its plants around the country over the past few years. Craig has extensive experience in the converting sector, having been with the Astrapak group for an extended period before moving to Tregger in Zimbabwe.

44 JUNE / JULY 2021

Les Whittal has joined Bordic in Johannesburg. With a career of 20-plus years in raw material supply to date, Les is now involved in sales of Bordic’s range of specialised films, labels (shrink, wraparound and IML) and aramid fibres (from Teijin), both in South Africa and into the SADEC region. The YouTube video on Bordic’s website about the many applications of Teijin’s aramid fibres is highly motivational, from jet planes to bridge building and firefighting to BASEjumping and paragliding, the uses are virtually endless – worth taking a look. Dr James Carson has been appointed GM at Anchor Chemicals in Maritzburg, which means a return to manufacturing for the man. Originally involved in tyre production at Goodyear in Uitenhage, James has also spent an extended period in academia as a lecturer in polymer chemistry at Nelson Mandela University in PE and, besides that, also threw in a stint as a restaurateur. More recently he was involved in the set-up of the tyre test lab as part of the REDISA tyre recycling

venture, until that project got shot down resulting in the effective termination of the tyre recycling business in South Africa. Anchor Chemicals, part of the Hobart/ Carst & Walker group, is a manufacturer of specialised plastics, rubber and adhesive materials including TPE, TPR and black masterbatch. James takes over from Crighton du Preez, who is pursuing other interests.

Clare has a Master’s Degree in Inorganic Chemistry and has worked in the 3M oil and gas business, as well as the metal finishing industry prior to that. She says she thoroughly enjoys immersing herself in the manufacturing sector and being exposed to new technologies – and polymer production and plastic extrusion and moulding has not disappointed!

Ken Barnes has joined Rubberchem. The former Protea Polymers man has possibly found his exact niche, having been operating in the rubber sector for most of his career. He is based in Durban and is thus the new Rubberchem rep for the region.

Farewell We regret to report that Sipho Khumalo passed away in March. Originally at Sun Ace South Africa, where he worked as lab manager, Sipho joined Aberdare Cables in 2009 and was employed as group compound technologist for cable manufacture. He left there a decade later, in 2019, and was at least partly involved with a group which was planning to put in a bid for a major local compounding business. Sipho was a well-spoken and quiet person who gave complete commitment to the businesses he was employed at.

George Nxumalo has joined Anchor Chemicals Pinetown (formerly Davro Compounding) in Durban. He was previously at Scott Bader, also in KZN, from 1999 until 2018. George started as a process controller in the polymer plant and over the years moved up to plant supervisor. After the polymer plant was shut down, he did the reporting on the MRP system which had just been adopted. He was then trained to do production planning on the system and was appointed as the production planner for the compounds and the colours plants, and then as the supervisor and production planner for the two plants. Clare Hennion has joined Safripol at its headquarters in Bryanston, Johannesburg, as national sales manager for polyolefins. Clare joined in April 2020 – great timing with polymers playing such a critical role in healthcare and food and beverage essential services. Clare makes regular road trips to Safripol’s plant in Sasolburg.

International Dr Mike Gradwell, who has been working at the South African Mint for the last few years, has accepted a position as managing director of a mint in Miami, Florida, and is due to relocate to the USA shortly. This is a big change for Mike, who at the end of 2020 was on the brink of returning to the plastic packaging industry as he was planning to buy a small packaging company. He was then offered the positon in the US and said it was “too good to turn down”. Mike was formerly a lecturer in polymer chemistry at Nelson Mandela University in PE and following that worked for Safripol for a number of years, in the research area.

Edward Smith is back at Precision Plastics in Brackenfell, Cape Town, after a venture to manufacture bulk bins in what was one of the biggest projects in the Western Cape converting industry in some years. Smith oversaw the complete set-up of the plant, from the layout to the installation and commissioning of the machines as well as all the peripherals and toolroom over an 18-month period. Edward, who established Precision Plastics in 1997, says he is happy to be back and one of the first results has been the huge expansion involving the purchasing of multiple large and small Tederic plastic injection moulding machines from Userve Plastic Machinery; and multiple delivery trucks and factory premises which was necessary for the expansion for the local and export fruit and medical industries as well the rebranding of Precision Plastics, which now sports a new, lighter logo and livery.

Plastics for Life

™

IN 2019, plastic products that meet the ultimate test of value by making our lives better in some way were honoured by the Society of Plastics Engineers SPE in the USA. A panel of judges selected the winners of the 6th annual Plastics for Life™ Global Parts Competition from among a wide range of parts that had already won in competitions at previous SPE events. The award categories and winners are:

GRAND PRIZE 2019 Sierra LD Thick Light Bar This application incorporates a new high transparency LED2245 PC used in a thick light bar to allow a sculptured ice appearance that meets a legal daytime running lamp function in an automotive headlamp. The novel light-pipe design incorporates non-standard multi-shot thick moulding, tooling and process to provide unique styling and function. This part required the development of a proprietary multi-shot moulding process to produce a low stress PC thick light bar with high clarity and minimal material shrink and warpage. Due to the large complex shape of the part, the tooling required a modified surface and special ejection design to properly eject the thick light bar. To meet the colour and optical clarity required by the product design, the resin was manufactured in a different process method than standard PC to provide very high optical clarity in extremely thick crosssections. This new PC material from Covestro provided crystal colour development to reduce yellowness in typical thick PC parts in the un-lit state. Enhanced CAE tools were required for the complex part and tooling design.

PEOPLE’S CHOICE Brewcraft’s Genesis 6 Gallon Carboy Fermenter This product was designed to replace glass carboys, which can break when dropped producing sharp glass and lost product and have narrow necks making it hard to clean. Natural HDPE allows the product to be seen through plastic for graduation readings that are clearly legible and embossed in both standard and metric volumes The integrated needle blown handles provide strength and rigidity through a unique pinchoff design for carrying full carboy while not compromising a comfortable grip. The wide neck opening is ideal during the use of brewing equipment and to aid in cleaning. The inside of the carboy is smooth and free of any voids or crevasses which could house bacteria, especially where the handles meet the carboy, which also allows for cleaning after the brewing process is completed. The chamfered base is designed to allow the carboy to tilt at an angle to siphon the last bits of product out of the container.

ThermaPANEL is a highly efficient modular hydronic heat exchange system used for radiant heating and cooling applications. The patented turbulent flow channel design transfer 250% more energy than traditional heat exchange systems with laminar flow properties. Panels are formed and tested to hold pressure up to 50 PSI at temperatures of up to 63°C. Individual panels are interconnected using plastic pipe in a secondary process that fusion welds the panels together using extruded PE-RT pipe. The fusion welding process reduces the amount of mechanical unions or joints needed during system installation, reducing both labour and materials cost for contractors and the opportunity for mechanical joints to fail. Each ThermaPANEL unit is individually insulated in a secondary process using EPS of varying density, depending on the load requirements of the application. ThermaPANEL systems are used in a variety of applications, from comfort radiant heating and cooling to snow and ice melting for egress for ground and pedestal mounted paver hardscapes. ThermaPANEL is the only modular heat exchange system designed specifically to radiantly heat or cool pedestal mounted pavers. Pedestal paver systems are quickly becoming the most popular construction method for creating amenity and utility spaces on flat roofs. These systems are used in all types of construction from residential units to commercial and industrial buildings. ThermaPANEL also replaces tubing systems for ground mounted pavers, providing highly efficient heat transfer for locations with high snow loads or intense sun exposure. Every component of ThermaPANEL is recyclable or reusable and is made 100% in the USA.

Eco-designers creating THE love affair between plastics and design is nothing new. From their ﬁrst appearance, designers started playing with them, happy to have found new materials that could keep up with all their creative fancies. That love affair shows no signs of fading, and eco-designers are now creating a new story for plastics. At a time when protecting the environment is no longer

simply a topic of discussion but has become a grassroots movement, many designers are focusing their efforts fully on the environmental impact of their creations. The idea today is to create differently: optimal use of resources, recyclability of products, integration of recycled materials, upcycling and eco-design is becoming second nature in all areas of industry.

Change begins with the choice of materials The popularity of the most ephemeral materials, often associated with fast fashion and packaging, is currently waning. The aim is to make objects last as long as possible and to ensure that all materials, whatever they may be, can be re-used or recycled. This translates into a much more streamlined style and the use of monomaterials to avoid, for example, a fake gemstone stuck on an ABS plate making the object aesthetically obsolete the day it comes off. This is a first step towards eco-design, but it is not the most decisive. Designers and the brands for which they make their creations, always on the lookout for the latest trends, are now striving to find ever more original recycled materials. Ikea, for example, has added the Order chair to its catalogue. The chair’s texture looks for all the world like cardboard and therefore creates the most original look. The chair is actually made from recycled PET and sustainably-grown wood fibres. This choice is far from trivial considering that the Swedish giant’s business model is based on mass production

Designers love the bottle Recycling marine waste, especially fishing nets, which are usually made of polyamide, is one of the major trends of the moment, at least in the clothing industry. Many start-ups are now proposing solutions to recycle them into a new fibre that is easy to weave and thus to use when designing new clothing. For Adidas, this approach has even become a leitmotif, as its global ambitions are so high. For example, it did not hesitate to modify its iconic Stan Smiths (sneakers inspired by the world of tennis and bestsellers for over 50 years). Since March 2021, this shoe model contains 50% recycled polyester. The environmental impact is far from neutral as this sneaker is sold by the tens of thousands worldwide. The German brand hopes to reach 100% recycled polyester by 2024. It also sells a pair of fully recyclable running shoes which must be returned to the manufacturer once they reach the end of their life. The polymer fibres are then recycled and used to manufacture new sports goods. And for those who still have doubts about the technical qualities of such models, this shoe has enabled athletes to break records in the half marathon.

a new story for plastics Re-using used bottles to make a stained-glass wall in a shopping mall, as seen here in Thailand, is a perfect example of upcycling

Recycled plastics are swimming in luxury For a few years now, Italian company Napapijri has been selling a jacket made from a blend of virgin and recycled polyamide, which is also completely recyclable. To ensure that the jacket is easily recyclable, the brand designed it using a single material: polyamide. At the end of its life, the ﬁbres are recycled using a process that preserves their original properties and quality. Like Adidas, Napapijri has set up a collection system to recover used jackets. Here again, the circle is complete! Sometimes recycled plastics appear where you least expect them. Recently, Tom Ford, the designer and former artistic director of the prestigious Gucci fashion house, made a big splash when he launched a high-end watch under his name, made from 100% recycled plastics – marine plastic waste, in particular, bottles. To understand the designer’s audacity, it is important to understand that such an association was totally unthinkable barely a decade ago. He claims that it takes 35 bottles to make one watch. He has even taken it a step further, as his watch’s packaging is made exclusively of various polymers also recovered from the sea. Finally, the strap is made of recycled nylon (polyamide) ﬁbres recovered from the ocean that are then hand-woven.

Even the luxury sector is taking an interest in recycled plastics. Famous designer Tom Ford is now selling a watch made entirely of polymers recovered from marine waste

Furniture: recycled plastics now welcome Awareness is also growing in the decoration and furniture sector. Even internationallyrenowned designers such as Philippe Starck are getting involved. Starck has developed a chair called I.E. made entirely from a recycled polymer in collaboration with Kartell, one of Italy’s leading design brands, which has been specialising in the manufacture of plastic objects for over 70 years. Which polymer was used? Kartell is keeping it a secret. All we know is that it comes from manufacturing scraps. Another original feature speciﬁc to this chair, and this explains its name, is that it was designed by an artiﬁcial intelligence that was able to answer the designer’s questions. The idea is to offer a beautiful, solid, ergonomic product manufactured using a minimum of energy and materials.

Polyamide is also popular with designers, notably the English design agency Layer, which has produced a range of furniture, including seats and screens, made entirely from recycled polyamide parachute fabrics. Polyester is gaining increasing recognition as its recycled form can now be found in many carpets

Jewellery designers are also jumping on the circular economy bandwagon. Russian designer Ekaterina Lukyanova, for example, sells an amazing range of jewellery made from recycled PET. Her creations are so original and daring that they recently made it into the Moscow Design Museum

Kartell, one of Italy’s leading design brands, revised one of its emblematic objects: the Componibili bedside table. For some years now, this table has been available in black or white versions made from a recycled polymer derived from industrial waste and known internally as a ‘recycled thermoplastic technopolymer’

Which plastics for tomorrow’s design? Finding new resources is also a priority for many designers. Their aim is not to get rid of polymers, which they often consider unrivalled in letting their imaginations run wild, but rather to ﬁnd new ones made from nonpetroleum-based raw materials. Biosourced plastics are a possible avenue but not a simple one to explore. Plant-based plastics such as PLA are also garnering attention from designers, especially those using 3D printers, like this chair by Yanko Design

The mono-material concept reduces complexity in the design process and permits integration of sensors, displays, antennas, cameras and more

Mono-material design unleashes smart lighting possibilities Building strength, durability and functionality into LED lighting innovation ADVANCED LED technology is revolutionizing lighting and security – but obstacles such as excessive heat and harsh elements can limit its potential. Covestro is innovating with a single plastic material to empower LED functionality in surprising ways – from security cameras to smart lamps. Makrolon® TC polycarbonate offers exceptional toughness, engineered to withstand even the most punishing heat, cold and impact. It dissipates heat coming from the LED and other internal electronic components. It can replace aluminum or metal, while reducing weight and cost, yet allowing greater design freedom. Versatile for any use, Makrolon LED grades are available in high transmission, diffusion quality, and reflective options in addition to custom colours. The mono-material concept reduces complexity in the design process and permits integration of sensors, displays, antennas, cameras and more.

54 JUNE / JULY 2021

LED lighting solutions that work smarter, harder Covestro put Makrolon PC to innovative use to develop a smart LED luminaire for public spaces. This singular material unleashes smart communication technology with situation awareness. Within one smart lamp, Covestro has integrated a Wi-Fi hot spot, camera lens, emergency warning speaker, time display, system status indicators and other built-in sensors. It takes more than a bright light to ensure safety. Thanks to Makrolon polycarbonate, a smart security camera light uses adaptive proximity technology to activate when intruders are detected. Surveillance features combine a high discharge LED light with IR and visual cameras plus audio warning functionality.

Mono-material design for LED lighting solves for sustainability Expansive design freedom is matched by a commitment to sustainability. Using Makrolon PC for multiple components greatly reduces complexity in the design process and allows for easier end of life recycling. Simply remove the circuit boards – because no screws are needed for mounting PCBs. And because Makrolon can replace metal and aluminum, weight and cost are reduced as well. Other key benefits include: Strength and durability – withstands heat, cold and impact Functional integration – can incorporate sensors, displays, antennas, cameras and more – almost any electronic component Thermal management – dissipates heat coming from LED and other internal electronic components Sustainability – reduced weight, parts and materials leads to more sustainable design Lightweight – can replace metal or aluminum for reduced weight and cost Brenntag is the distributor for Covestro Makrolon® in South Africa. For more information, contact Rudi Verwey if you are interested and need technical input to manufacture similar lighting in SA.

Canada adds plastic products to list of ‘toxic’ substances THE Canadian government has officially added ‘plastic manufactured items’ to its list of toxic substances on Schedule 1 of the Canadian Environmental Protection Act (CEPA). While drawing praise from some environmental groups, industry associations, including the Ottawabased Chemistry Industry Association of Canada (CIAC), expressed disappointment with the announcement. “We remain concerned that today’s decision sends the wrong message to global chemistry investors, namely that Canada is ambivalent about the enormous investment prospects for the circular economy for plastics,” CIAC said. “We’re disappointed that safe inert plastic materials that play such important roles in Canadians lives are being labelled as toxic substances.” CIAC also said it would keep working toward extended producer responsibility systems in all provinces and advocate for better recycling access and stronger technology around mechanical and chemical, or advanced, recycling. And in the US, the American Chemistry Council (ACC) said in a statement that a CEPA listing is misleading and counterproductive. “Banning efficient plastic products will likely lead to forced substitutions with alternatives that increase greenhouse gas emissions and prevent the transition to a low-carbon future,” Joshua Baca, vice president of plastics with the ACC, said. And the Washington, DC-based Plastics Industry Association weighed in with its own criticism. “Our two countries are powerful plastics economies,” said president and CEO Tony Radoszewski. “This development is a symbolic gesture to activists and threatens tens of billions of dollars of commerce. The idea that plastic is toxic is the true danger. Such a label could have ramifications far beyond some singleuse items. It could fast-track more bans on other consumer products that are fully recyclable. Our main concern should be improving recycling.”

SOCAR Polymer has two new impact copolymer polypropylene grades ideal for rigid, thin-wall packaging

www.socarpolymer.az

Two new impact copolymer PP grades for rigid, thin-wall packaging Milliken’s Hyperform HPN performance additive boosts productivity, reduces moulders’ energy use SOCAR Polymer has introduced two new grades of impact copolymer polypropylene (ICP) resins that are the first in its portfolio to incorporate Milliken Chemical’s Hyperform® HPN® performance additive for PP. SOCAR, based in Azerbaijan, is currently marketing these materials to customers in Russia, Turkey and other countries in the Commonwealth of Independent States. The company says these new ICP grades are ideal for use in thin-wall injection moulded (TWIM) packaging applications such as caps, closures and opaque containers, as well as in various housewares, sporting goods and toys. The two new grades are CB

4848 MO (with a melt flow rate of 48) and CB 6448 MO (with a melt flow rate of 64), which are the most common melt flow rates for ICPs. Both offer an excellent balance of end-use properties. These ICP grades deliver moulded parts that exhibit low shrinkage, improved thermal resistance (HDT), and an excellent balance between stiffness and impact resistance. Additionally, with their good flowability, the two different grades enable converters to realize faster processing, while allowing both newer and older injection moulding machines to efficiently process the material.

Polycarbonates for LED lights in extreme environments LED light sources have proven to be energy-saving and long-lasting which makes them economical light sources and are widely used in buildings, vehicles and street lighting. Operating LED lamps under water puts special demands on the materials involved. In cooperation with Brazilian swimming pool equipment supplier Ecopyre Lighting, Covestro developed an integrated solution using the thermally conductive polycarbonate Makrolon® TC. It features high dimensional stability during manufacture and operation of the lights, thereby preventing water ingress (ingress protection or IP). The letters ‘TC’ in the type designation stand for ‘thermally conductive’ and indicate that the plastic also has good thermal conductivity. This makes it ideal – like the other types in the TC portfolio – for efficient thermal management in which the heat generated by the LEDs is well dissipated. In addition, the plastic complies with the chemical resistance required for use in swimming pool water. www.covestro.com

‘Mask Buddy’ relies on Engel

ENGEL injection moulding solutions for highly flexible multi-component production JOINING forces, companies in the plastics industry are making important contributions to the fight against the Covid-19 pandemic. One of these contributions comes from Fischlham in Upper Austria, the home of ACH Solution. The mould maker and system provider, which specialises in silicone and multi-component processes, has set up a production line for its own respiratory protection product. The innovative FFP2 masks also offer more safety and comfort in industry and building work. ‘Mask Buddy’ is the name of the new product and also of the company that ACH Solution founded for the production and distribution of the masks. In the development of this new type of premium mask, the focus was on the aspects of wearing comfort, breathing air quality and environmental protection. Long-standing partner Engel, has supplied two e-victory injection moulding machines which grow in a versatile way to match the company’s needs. The housing for the mask can be

used for many years, and the filters can be changed easily. This significantly reduces the waste generated by conventional FFP2 masks. The new mask type owes its wearing comfort to silicone which helps to seal off the face with a soft, skin-compatible silicone lip that precisely adapts to the face contours. As the air breathed out is reliably discharged downwards and cannot escape upwards, glasses do not mist up and eyes do not dry out. To be able to produce large quantities in a short time, ACH Solution invested in two new injection moulding machines from Engel, each equipped with an Engel viper linear robot. The further automation as well as the LSR plasticising technology were developed in-house. Since the beginning of the pandemic, Covid-19-relevant projects have been given priority in the machine manufacturer’s production plants. Two-component production with maximum flexibility Four parts of the premium mask are produced by injection moulding: the two

filter housing halves, the valve and the valve closure, which is used wherever an even higher protection level is prescribed or the regionally applicable pandemic legislation does not permit masks with an exhalation valve. Flexibility is the key requirement, not only in the design of the masks but also in the layout of the new production cell. The two new injection moulding machines – an e-victory 120 and an e-victory 160 – are designed for processing both liquid silicone rubber (LSR) and thermoplastics and can therefore be used in a versatile way – if necessary also with other products or for mould sampling. The hard components of the mask are made of polycarbonate. Besides the sealing lip, the valve and the valve closure are also produced from silicone. The machines can be converted from one material to the other in less than two hours. To do this, the plasticising unit is replaced and the control unit adapted. Basically, a thermoplastic machine is a pared-down LSR machine. LSR processing requires some additional components, such as

The viper robot removes the finished parts and deposits the substrates in the four cavities for silicone processing

Thanks to a silicone lip, the new premium mask combines safe respiratory protection with wearing comfort. The filters can be easily clipped into the durable housing

a vacuum pump, gate valve control or a dosing signal. Engel provides both the hardware and the software for this, and the individual functions can be activated and deactivated very easily on the machines’ CC300 control unit. The mask housing, the part that points towards the face when worn, is the exciting bit. In a first step, the basic housing bodies are moulded from PC in a four-cavity mould on the e-victory machine with a clamping force of 120 tons. The substrates are fed to the second production cell via a separator and aligned with camera support so that the articulated robot can pick up the parts in the correct orientation and transfer them to the centering station with four depositing positions. The viper linear robot takes over from there. It places the set of four in the mould of the 160-ton machine, where the mask housings are fitted with the silicone lip in a second injection moulding step. The viper removes the two-component finished parts and cycles them out of the production cell via a belt conveyor. The masks are assembled on site, fitted with an elastic fixing strap and

packaged. Mask Buddy supplies all of Europe and part of the USA. Other regions are covered by partner company and licensor PPC in Australia. Maximum process stability and repeatability ACH Solution has been using Engel injection moulding machines with different clamping forces for sampling for many years. Tie-bar-less injection moulding machines, and this also includes the e-victory series machines, are preferred because they support flexible production in the best possible way. Since there are no tie-bars to interfere with production, even very large and complex moulds can be easily and conveniently mounted without having to dismantle core-pulls or other functional elements. This speeds up the mould setup processes and increases the productive time of the machines. The further demands on the injection moulding machines are high repeatability and process stability. And this again applies to both business areas, mould sampling and mask production. Several factors contribute

A well-coordinated team: Leopold Praher from Engel Austria, with Christian Hefner and Andreas Penninger from ACH Solution

to the high precision of the e-victory machines. They include the electric injection units on the hybrid machines as well as the special design of the tie-bar-less clamping unit, which keeps the mould mounting platens precisely parallel to each other throughout the entire injection moulding cycle. Added to this are the force dividers, which distribute the clamping force evenly over the mould mounting platens. For added safety, the mask moulds rely on Servoshot 2G. The electric valve gate system developed by ACH Solution makes it possible to control each valve gate individually in order to keep the filling level constant across all cavities throughout the entire production process. The process is self-regulating and ensures consistently high product quality.

Complete process managed by the machine control unit Servoshot 2G and the mould deliver essential process data, which ACH Solution stores and uses for continuous process optimisation. Using OPC UA, the company can connect its smart mould technology and peripheral units with the smart injection moulding machine. There is already a Euromap recommendation for connecting LSR metering technology via OPC UA. This means that the entire process can already be viewed, managed and documented using the CC300 control unit on the e-victory machines.

Silo mentality and selﬁshness

will get us nowhere! Opportunity for South African plastics industry to create a new footprint BY KIRTIDA BHANA

I AM certain that all the ‘Architects of Strategy’ in our industry have spent time analyzing and interpreting The South African Economic Reconstruction and Recovery Plan aimed at stimulating equitable and inclusive growth. The plan/policy was developed after Covid-19 exacerbated the critical challenges facing the majority of South Africans viz. inequality; unemployment; poverty; declining economic growth and declining investment. Silo mentality and selfishness will get us nowhere in this plan! If, as an organisation, you are happy operating in your little bubble and are satisfied that you have paved the way for your organisation’s growth path and are doing fine…Allow me to remind you of this powerful African proverb: “If you want to go fast, go alone. If you want to go far, go together.” Our economies sustained low levels of growth and a series of downgrades have impacted negatively on the climate of doing business in South Africa. • How do we as an industry make best use of creating opportunities within government’s recovery plan? The priority interventions are: • Aggressive infrastructure investment; • Employment orientated strategic localisation, reindustrialization and export promotion; • Energy security; • Support for tourism recovery and growth; • Gender equality and economic inclusion of women and youth; • Green economy interventions; • Mass public employment interventions • Strengthening food security; and • Macro-economic interventions. The plastics industry already plays an important role but how do we amplify our role in ALL these interventions to play a critical role in South Africa’s economic recovery. Large-scale collaboration and strategic partnering to supply goods and services within these interventions are what we urgently need to be co-creating. How do we as 60

INVENTING.indd 60

an industry collaborate and partner to fulﬁll requirements within these interventions and become part of the recovery plan for our country?

How do we as an industry collaborate and partner to fulfill requirements within these interventions and become part of the recovery plan for our country?

Golden opportunity for the South African plastics Industry This is a golden opportunity for the South African plastics industry to create a new footprint, thereby panel-beating the huge dent in our reputation as the industry with the biggest waste footprint in the environment. Big meaningful actions will have a huge impact on Government’s targets for these priority interventions that will put us on the map as a key priority sector, without which Government will not be able to deliver their promises to the nation. These interventions are a strong guide for our industry to refocus and reset our own priorities to align with the big picture to beneﬁt society at large. The key enablers as per the plan are: • Resource mobilization; • Regulatory changes, a supportive policy environment and enabling conditions for ease of doing business; • Building a capable state; • Social compacting; • Skills development; and • Economic diplomacy and further integration into the African continent The collective impact of these interventions is aimed at achieving the targets set by the National Development Plan (NDP) Vision 2030. Are we as an industry going to sit this one out? I leave you with another African proverb until next time: “He who thinks he is leading and has no one following him is only taking a walk.” • To learn more about Strategy in Innovation contact: Kirtida Bhana at Plastics|SA. email: Kirtida.bhana@plasticssa.co.za or mobile: 082 322 0117

What future does polyethylene have? Banning of single-use plastics not necessarily a threat to the polymer industry BY NIALL MARSHALL

THE biggest volume market for plastics, and especially polyethylene, is packaging. Some of that packaging is reusable but most of it is disposable – the dreaded ‘single use plastic’ category. With an estimated 55% of all plastics being used in packaging, the question being asked is (even in the Middle East) “what future does polyethylene have?” In 2018 the EU published ‘The European Strategy for Plastics in a Circular Economy’ which focused on areas such as encouraging design for recyclability, boosting demand for recycled plastics, preventing plastic waste in the environment and how to improve and harmonise collection and sorting of polymer for reuse. This was followed by the amended Packaging and Packaging Waste Directive which, among other things, revised recycling targets among all materials (not only polymers) as well as set the requirement that all plastic packaging placed on the EU market should be reusable or easily recyclable. Some of these targets will be extremely difﬁcult to attain, still they will drive product design philosophies and result in increased recycling (rather than shipping plastic waste to Asia). Plastics bans proliferating As with many regulations the EU is in the frontline, but similar regulations have also started to appear in other regions. In 2020 China announced a ban/phase-out of single use plastics in key cities which will then be rolled out through the country. The ﬁrst products to be phased out are expanded polystyrene (EPS) packaging, drinking straws, plastic bags and tableware. Even the USA is implementing plastic bans. Nine states have already introduced bans on the use of single-use plastic bags 64

Middle East.indd 64

and disposable polystyrene food containers, straws, plastic utensils and cups. New York recently became the second state (after California) to prohibit hotels from offering their guests personal care products in single-use plastic bottles. New Jersey has even gone so far as to ban the use of single-use paper bags from grocery stores (effective May 2022). Generally, moves to ban plastics, especially single-use plastics, has been muted during the pandemic when the sanitary benefits of single-use plastics have been widely recognized. At the same time an increased reliance on take-away food deliveries and on-line shopping have increased demand for packaging. Disposable gloves and masks have become ubiquitous and increased demand for polymer in these applications, even as other markets, such as automotive, have shrunk. But undoubtedly the legislative pressure on reducing or eliminating the use of plastic packaging will return and the polymer industry is evaluating the threats and investigating the opportunities. Plastic packaging is either rigid or flexible. Flexible packaging are films, usually based on polyethylene or polypropylene, and they can be used for primary packaging (to give immediate protection to the packaged product) or as secondary packaging such as overwrap, labels or pallet wrap. Rigid plastic packaging includes bottles, pails, cups, tubs, and closures usually produced by injection moulding, thermoforming or blow moulding.

Replacing single-use plastic with single-use paper doesn’t address sustainability Most primary packaging is single use, it is disposed of once the packaged item is used. The value of primary packaging is that it protects the item or prolongs its life (as

JUN / JUL 2020

2021/06/08 16:10

in the case of food) and it is therefore unlikely that primary packaging can be replaced with an alternative packaging that provides better protection or is cheaper. Replacing single-use plastic with single-use paper doesn’t address any sustainability or environmental concerns. Some single-use secondary packaging is important to protect the items and for handling, but there is an opportunity to reduce some secondary packaging, either with reusable packaging or simply by eliminating unnecessary packaging. Opportunity for Middle East polyethylene producers to offer specialty polymers The EU plastic packaging regulations require that all plastic packaging placed on the EU market to be reusable or easily recyclable (where mechanical-, chemicalor biological-recycling are acceptable). Mechanical recycling will require that packaging is designed using mono-materials (metallised ﬁlm and many multi-polymer multilayer constructions cannot easily be recycled) – an opportunity for the large volume Middle East polyethylene producers to offer specialty polymers (such as metallocene polyethylene as well as barrier resins). An emphasis on mechanical recycling will also result

in a demand for up-gauging – it is more cost effective to collect heavier plastic bags (which also tend to be used more than once despite not necessarily being stronger) than down-gauged bags. And then there is chemical recycling that converts plastic Banning of waste into chemicals provide a potential new source single-use plastics of feedstocks such as is not as simple as it monomers, oligomers, sounds, but it is also not and higher hydrocarbons necessarily a threat to the for the petrochemical plants that can in turn polymer industry, at least be used to make virgin not as the Middle East polymers. This is still polymer industries’ a long way from being view commercially viable (both in terms of cost and scale), but it is on the radar! Banning of single-use plastics is not as simple as it sounds, but it is also not necessarily a threat to the polymer industry, at least not as the Middle East polymer industries’ view.

CHINAPLAS 2021 a huge success! 152 134 visitors joined the mega show

CHINAPLAS 2021 was concluded on 16 April with a total of 152 134 visitors (149 771 local and 2 363 overseas). Despite the Covid-19 pandemic and the move to the new venue at Shenzhen World Exhibition & Convention Centre, Chinaplas once again proved itself to be a high standard platform for presenting new technologies and sourcing the latest products for the plastics and rubber industries. While the mandatory two-week quarantine for travellers coming from outside mainland China deterred almost all overseas visitors to Chinaplas this year, a few hardy people made the choice. Chinaplas said only 577 of the 44 000 visitors on the ﬁrst day of the show were not mainland Chinese attendees, compared with about 20% overseas in a normal year. Chinaplas is the plastics industry’s ﬁrst global show not to have to cancel since the pandemic started. Though the total number of visitors

this year dropped by 6.85%, the number of local visitors increased by 23.46% compared to the previous edition of show in Guangzhou in 2019. In addition, the ofﬁcial live streaming platform attracted 363 000 audiences and helped Chinaplas reach out to global buyers throughout the four days. With an exhibition area of over 350 000m2, Chinaplas 2021 hosted more than 3 600 leading exhibitors from all over the world, showcasing more than 3 800 machines, raw materials, chemicals and other solutions. Apart from countless exhibits and showcases, Chinaplas 2021 also hosted a series of concurrent events under the theme of ‘New Era. New Potential.

Monomaterials and digital recycling solutions REIFENHÄUSER’s focus at the show was on sustainable packaging solutions for a functioning circular economy. As a leading solution provider for circular economy products, Reifenhäuser promoted its production machines for monomaterial composites as well as other components. The problem with today’s plastic packaging lies primarily in the material mix which cannot be separated in the recycling phase, or only with great difficulty. Therefore, no pure recyclates are obtainable from standard packaging, which explains why recyclability is low. The solution: Customers produce monomaterial laminates (All-PE film) for flexible packaging on Reifenhäuser EVO Ultra Stretch blown film lines. The regular PET layer is replaced by stretched PE. With maximum stretching of up to 1:10, the Ultra Stretch stretching unit gives PE film completely new mechanical properties. This is a simple replacement for PET and there is no need to adapt downstream processing steps. The unique and patented position of the stretching unit directly in the haul-off of the blown film line makes the process particularly stable and efficient. The Ultra Stretch process is unique on the market

and offers decisive advantages over ﬁlm stretching that takes place conventionally between the haul-off and the winder. Reifenhäuser also presented a special highlight at the show: To be able to recycle fully recyclable plastic packaging at a high standard, special marking and data standards are required to identify packaging reliably when sorting waste streams and to make recycling properties transparent. Reifenhäuser is promoting the R-Cycle tracing standard which is driven by a cross-company initiative. The standard can be networked as an open industry platform on all production and processing machines along the plastic packaging value chain and can store recycling relevant information automatically in a digital product passport. This information can then be retrieved in the waste sorting phase using digital watermarks in the www.reifenhauser.com printed image of the packaging. JUN / JUL 2021

Innovative solutions for engineering plastics GERMAN specialty chemicals company Lanxess showcased new products, technologies and solutions for engineering plastics, flame retardant plastics and plastics colouring.

Large-scale manufacturing platform for electric jetboards Lighter weight construction provided weight savings of around 25%

COBRA International in Thailand, one of the world’s largest OEM manufacturers of composite goods for water sports, automotive, marine and civil engineering, is collaborating with Radinn to mass produce its new range of electric powered surfboards. Swedish innovators, Radinn, produce some of the fastest jetboards on the market. Originally launched in 2018, the production requirement ramped up quickly and with a target to reduce overall board weight, Radinn required both a technical development partner and a large-scale manufacturing platform. Sample boards were shipped to Thailand, and four of the Radinn team travelled to Cobra to set up the project. Almost immediately, the Cobra team was able to suggest improvements. Having reviewed the existing boards – thermoformed plastic shells with an injected PU foam core – a switch to a lower density EPS foam core and moulded glassﬁbre skins was proposed. This lighter weight construction provided 72

JUN / JUL 2021

weight savings of around 25% whilst maintaining the durability required by riders. An additional benefit was the removal of the edge seam around the board’s rails, with the new seamless moulded boards having a cleaner look and improved performance on the water. A key part of the Radinn design concept is its modular approach. With different battery Powerpacks dropping into a pocket in the deck, and the Jetpack propulsion unit fitting into the board’s base, absolute precision of the moulded shape was critical. Working from Radinn’s initial CAD data, master board plugs were produced for the Freeride and Carve models, before test assembly and final sign off for production was agreed. Radinn boards use a custom laminate made up from several plies of woven and stitched biaxial fibreglass fabrics, moulded with epoxy resins to produce a tough monolithic shell. With production following Cobra’s lean manufacturing principles, the company is able to deliver at the target rate of 300 boards per month. www.cobrainter.com
