Roto gathers throughout the world! As another year comes to an end, it can be both an anxious and We have an important technical article inside discussing rewarding time. Last year may have been a very good year for you the use of simulation in the development of Hydrogen Storage and your business, which is wonderful. However, there may have Vessels. This work is ongoing at Queen’s University Belfast results not been enough time for you to achieve all your goals, which can from a need for long-term security combined with a desire to be frustrating. have cleaner solutions that do not contribute to global warming. We in the rotational molding industry are fortunate. Many, Hydrogen storage vessels, especially for commercial sectors, especially those involved in the Roto industry’s trade associations will be a big topic throughout the coming year. It presents the throughout the world, are given the chance to learn what is new potential for cleaner solutions and new markets for rotomolders and what advancements are on the horizon. We are given the chance to forge important business and even lifetime relationships. I’ve learned these opportunities are invaluable as I’ve seen rotomolders around the world helping each other in ways you can’t put a price on. It is my hope that 2024 will only be enhanced by more and more of these kinds of experiences. I am excited to hear and report on the success stories that are sure to come in the year ahead. I hope you will find this issue both motivating and inspiring. It is full of articles covering what has been happening throughout The ARMO Board, Representatives, and Guest in Poznań, Poland L-R Front Row: S.B.

UPFRONT NOVA Chemicals and Plastic Energy Launch Feasibility Study on Advanced Recycling Plant to Further Canadian Circularity Aspirations • Facility would be constructed in the Sarnia, Ontario, region. • If constructed, would be largest facility of its kind in Canada to date. • Investment would build on already CAD 2 billion injected into Province of Ontario.

CALGARY, AB CANADA — NOVA Chemicals

Corporation (“NOVA Chemicals”) and Plastic Energy have entered into an agreement to explore the feasibility of developing a pyrolysis-driven advanced recycling facility in the Sarnia, Ontario, region. If constructed, the facility would be the largest of its kind in Canada with a potential initial capacity of 66kt per annum. “Post-use plastics offer tremendous value to furthering the circular economy, and our teams at NOVA Chemicals work daily to innovate new and collaborative ways to extend the lifecycle of our products and plastic packaging,” said Greg DeKunder, VP, NOVA Circular Solutions. “This agreement with Plastic Energy is a prime example of two companies working together to create timely, effective, and sustainable solutions that will help us make progress towards our 2030 recycled plastics ambitions, while diverting hardto-recycle segments of plastic waste away from landfills.” Plastic Energy is one of the world’s leading advanced recycling technology companies through use of its patented TAC™ process to treat post-consumer plastic waste. Recycled polyethylene manufactured using Plastic Energy-produced feedstock, called TACOIL™, has identical properties to virgin polyethylene and can be used in food contact and high-performance applications, helping manufacturers and packagers achieve their recycled

content goals. Plastic Energy has two commercial recycling plants in Spain that have been in operation for seven years, alongside new projects in Europe and Asia. “We are pleased to sign this agreement with NOVA Chemicals to explore the scope for our first advanced recycling project in Canada,” said Carlos Monreal, Founder and CEO of Plastic Energy. “Advanced recycling will continue to be important for the North American market by providing a solution for incorporating recycled content into food-grade packaging. Together with NOVA Chemicals, we aim to reduce the amount of plastic waste ending up in landfills, incineration, or as leakage into the environment, which is important for the circular economy in Canada.” NOVA Chemicals recently announced its aspiration to reach 30 per cent recycled content as a share of its total polyethylene sales by 2030 in its Roadmap to Sustainability Leadership, including its commitment to build a state of the art mechanical recycling business and continue exploring world-leading and proven advanced recycling technologies. If built, this new facility would see NOVA Chemicals build on its already CAD 2 billion investment into Ontario to inject additional new technology, jobs, and long-term viability into the local and Canadian economies.

Chevron Phillips Chemical announces first class of operators for Golden Triangle Polymers facility. Chevron Phillips Chemical Company LP, as Operator for Golden Triangle Polymers, onboarded its first class of 28 process operators this week for the world-scale integrated polymers facility under construction in Orange County, Texas. The newly hired operators come primarily from the nine-County Golden Triangle region. “Operations makes up most of the workforce for our petrochemical facilities, and these highly skilled employees are the backbone of what we do, helping to ensure we operate safely and reliably. As a newly constructed plant, welcoming this first class of operators is a historic milestone. This facility will provide good paying jobs and economic benefits for decades to come, and people will look back and remember this team as having started it all,” said Chad Jennings, plant manager for Golden Triangle Polymers. Golden Triangle Polymers is a joint venture between Chevron Phillips Chemical and an indirect subsidiary of QatarEnergy.

Chevron Phillips Chemical is managing engineering, procurement, and construction for the project and will operate the facility after start-up. Local First is a program Golden Triangle Polymers launched earlier this year with a $400,000 donation. Through the Local First program, the company is collaborating with Orange County and Workforce Solutions Southeast Texas to prioritize Orange County and the Golden Triangle region first when sourcing suppliers, vendors, and workforce. The employment portion of Local First aims to help workers from the nine-county Golden Triangle region find and compete for job opportunities through public communications, public job fairs and information sessions, and resource referrals. The nine counties that make up Local First employment are Orange, Jefferson, Hardin, Jasper, Newton, Liberty, Tyler, Chambers, and the Bolivar Peninsula area of Galveston. www.rotoworldmag.com 15

UPFRONT SIGD Student Wins Rotational Molding Design Competition Industrial Design student Jack Hardy has been named the winner of the 2023 Rotational Molding Product Design Competition. SIGD student Jack Hardy has been named the winner of 2023 Rotational Molding Product Design Competition sponsored by Winsell Granites for Plastics. Sponsored by Winsell, a company that specializes in graniteeffect colorants for plastic rotational molding, the theme of the competition was “Backyard Experience.” Participants were required to create outdoor recreational products that would be manufactured primarily through rotational molding using Winsell granites. Hardy’s winning entry was the OnPar Putting Green. Hardy, a senior in the School of Industrial and Graphic Design (SIGD), created his putting green design in his third year Product Design Studio taught by Associate Professor Joyce Thomas. Thomas challenged her students to create a unique product for outdoor recreation that encourages wholesome and sustainable activities movement, exercise, health, and well-being. In creating a “Backyard Experience,” students sought thoughtful solutions that have high market potential and visual appeal and fit on a standard shipping pallet. “I felt that not only was there room for a higher-quality golf green but also for one that was more exciting than all others available.” — Jack Hardy

When he heard the competition was open to all students studying design and engineering, Hardy immediately knew he wanted to enter. “I was excited to hear about this opportunity because I have a competitive spirit and am always up for a challenge,” he stated. He began by researching the capabilities and limitations of rotational molding and then looked into the market for putting greens. “I found that many golf greens are for indoor use and don’t pose much of a challenge for the user. I felt that not only was there room for a higher-quality golf green but also for one that was more exciting than all others available.” He explored challenging greens on major golf courses and incorporated their topographies into his design. Hardy’s OnPar Putting Green features an eight-piece assembly with padded turf and porous surfaces for drainage. The green can easily be disassembled for storage. Hardy says the putting green concept was the perfect product to be made with this production technique. “Rotational molding allows you to make large plastic pieces with consistent surface thickness, and Winsell’s granite-effect colorants also make for visually appealing indoor/outdoor backyard furniture and accessories.” Thomas says that Jack found the competition’s theme to be a great opportunity to combine his two passions of golf and industrial design. “He used a human-centered design approach in problem finding and drove toward an innovative design solution. People who have seen the OnPar Putting Green are asking when and where they can buy it!”

ARMO 2023

International Rotational Moulding Conference Susan Gibson, JSJ Productions, Inc.

22 ROTOWORLD® ISSUE 4 • 2023

The ARMO2023 conference took place in Poznań, Poland this year. Positive energy was loud and clear throughout the largest European conference that takes place for the rotational molding industry. The attendees rated it nothing short of a grand success. Attendees were happy to come together once again after several years off due to the Covid pandemic. Organized by Rotopol (Polish Rotomoulding Association) and BPF (British Plastics Federation), ARMO2023 was held September 10-12 at the new Poznań Congress Centre. The conference drew more than 570 attendees including rotomolders, suppliers, and other professionals. The education program was in high gear as industry hot topics were addressed and there was a big focus on creating a circular economy and sustainability within the industry. The ARMO Trade Exhibition featured more than 65 companies with their products and innovations on display. There was plenty of social and networking time allowing attendees to visit with colleagues and make new friends within the industry. ARMO Chair Wayne Wiid kicked off the program with a warm welcome to the international audience. Rotopol Chair Marek Szostak extended his welcome and gave an interesting overview of Poznań, which is the fifth largest city in Poland. “Poznań is a hotbed of the rotational moulding industry in Poland and a major centre for business and trade shows,” Szostak said. This was followed by a welcome from Poznań’s Director of City Relations, Ms. Anna Pavlovich. “On behalf of the city, I thank you for being here and creating a better future for us in Poznań,” Poznań has 1MM people in the total area including 20 universities and more than 1,000 companies,” she said. Poznań is rich in history, education, and industry. Anna Kozera-Szalkowska, Plastics Europe Polska, presented an overview of the plastics industry in Europe and specifically in Poland. “At the end of 2021, the plastics industry employed 1.5 million people, and was represented by 52,000 companies (most of which are SME’s) distributed across the European Union,” she said. “The European plastics industry had a 405 billion Euro turnover in 2021, but due to the energy crisis, high energy intensive manufacturing slowed down, and for the first time in many years the import of goods was bigger than the export,” she said. In 2022, plastics production grew by 10.7% in Poland compared to the year prior. The most dynamic development came from the automotive sector, of which production increased by 18.6% compared to the year prior. “The numbers for 2023

may not be as good as the first few months have indicated a slowdown in Poland plastics production,” she said. Under the theme Sustainable Rotational Moulding many presenters took the stage to report on their progress in the areas of research and company dedication to a circular economy and sustainability to protect the future. Steve Harrington, Matrix Polymers, said, “We know that plastics are doing good things in the world. There is a surge in the number of executives working toward sustainability and who view this as critical to the future of their business. Sustainability is fulfilling the needs of the current generation in terms of energy, PCR, mass balance model, Hydrogen, PCR circular economy, new materials, and plastics pollution, to name a few.” he said. Harrington reported Matrix initiatives include solar panels at production plants, energy, and water usage, and sponsoring a PhD program at Queens University Belfast.

By 2030, all plastics packaging placed on the EU market must either be reusable or can be recycled in a cost-effective manner. By 2030, more than half of plastics waste generated in Europe will be recycled. Plastic recycling in Europe has increased by 17% in 2021 over 2020, reaching 11.3 million tons in 2021 and 8.7 billion in turnover. The EU aims to be climate-neutral by 2050 with net-zero greenhouse gas emissions. This initiative is at the heart of the European Green Deal and in line with EU’s commitment to global climate action under the Paris Agreement.

“We have decided to change and go for the sustainable road, and we’ve established a 20-initiatives plan to achieve that goal,” he said. Ravi Kumar, Roots Multiclean, presented a look at the future in sustainability the India way. “Natural resources are turned into products that are ultimately destined to become waste because of the way they have been designed and manufactured,” he said. The linear economy is one of take, make, use, and waste, but the big question is, “How long can this go on?” A circular economy is an economic system designed with the intention that maximizes the use of resources extracted from nature and minimizes waste. Natural resources are turned into products to consume and regenerates back to the resources autonomously to achieve a sustainable eco system. “Circularity is not a new concept. Governments and industries have been experimenting with circularity initiatives for quite some time, but mainly focused on recycling,” he said. “We must go beyond just recycling and waste management. We must replace the end-of-life concept with restoration. The time is coming when it no longer makes

economic sense for business as usual. It’s time for every industry to launch circular transformation initiatives to prosper and survive, even in times of disruption while achieving sustainable growth.” Andrew Byrne, Corcoran, presented a look at the Corcoran Group Polymer Division. Corcoran was established in 1939 and has been in business for 84 years. The distribution company has offices and distribution sites with 50 staff throughout Ireland, UK, and Europe. Markets include polymers, industrial applications, packaging, pharmaceutical and veterinary, cosmetics, food ingredients, and construction/installation. Corcoran focused on reduction of plastics waste since 2006 as a grinding facility. The

company is now a full compounding facility with state-of-the art machinery. They are currently engaged in closed loop recycling programme trials. Professor Xie Pengcheng, Beijing University of Chemical Technology, reported on important research on the design method and rotational molding process of the type IV Hydrogen Storage Tank Liner. “High pressure Gaseous Hydrogen storage is a more mature technology than others at this stage,” he said. “High pressure tanks are an important carrier connecting the whole Hydrogen industrial network production, storage, transportation, refueling, and utilization.” He gave a comparison between manufacturing the liners with rotational moulding and blow molding. China has mainly focused on using rotational molding, as has America and France. “Hydrogen barrier properties, temperature stability, resistance, toughness, melt index, homogeneity, etc. of the liner material are the key factors affecting the liner’s processability and serviceability,” he said. The advantages of rotomolding for the liners are that it is a simple molding process, has free molding size access, wall thickness, good edge strength, and is without internal stress. The challenges are strict requirements on raw particle size, complex dome part molding, wall thickness, and dimensional stability control. Dr. Gareth McDowell, 493k, talked about where energy goes during rotomolding. The minimum energy required is for heat

+ rotation + air movement + control system. The total energy expended is gas + electrical consumption. McDowell gave an example of heat energy required for a 1-cu. metre, 8mm wall aluminum tool with PE shot weight of 28kg (5mm wall). “Start with a measured response, making sure the oven is always full, consider slowing your arm rotation after the powder has been laid down, take steps to reduce wasted energy, improve electrical systems, and control your process,” McDowell said. “As an industry it is easy to use a phenomenal amount of energy, but if we measure and maximize our process and efficiencies, transforming as much kg PE) per cycle as possible, then we can begin to establish an industry-

wide case that becomes quite defensible in the face of increasing energy usage audits.” David Smith, ARM and Muehlstein, talked about the North American Rotomolding industry. “The North American Rotomolding industry is strong, with numerous new molding firms in recent years,” he said. The Association of Rotational Molders (ARM) has expanded its membership over the last year and experienced a 40% growth over the past 5 years. There is still a lot of industry consolidation with Tank Holding and Myers Industries adding to their portfolios to become North America’s largest rotomolding entities. The average molding company in North America achieved a 15% annual growth in 2022. He presented the top custom rotomolders, top captive rotational molders, top proprietary rotational molders, and top rotational molders by total sales. The materials being used primarily in North America include PE, XLPE, PP, Nylon, and Acetal. The top market sectors include tanks, agriculture, industrial, recreational and sporting goods, non-tank industrial applications, lawn and garden, and consumer products. “The industry is strong, participants are increasing, materials are slowly diversifying, markets are increasing, and the future looks great,” he said.

material, bio-based content, biodegradable materials, and lightweight foams. “Virgin polyethylene is the most used material in rotomolding, but there are many more other sustainable solutions,” Thometschek said. Maisyn Picard, Ingenia Polymers, said the company started in 1986, and is a niche player in the rotational molding industry with a track record of developing innovative products including Rotolite®, a one-shot foamable system, Rototuf®, an advanced linear system, and Superlink®, a high performance XLPE. Angelique Brocatus-Kooijmans, LyondellBasell, presented the LyondellBasell rotational molding strategy for our changing world. “LyondellBasell is a leader in the global chemical industry creating solutions for everyday sustainable living. LyondellBassell is the global and the number one producer of PE and PP in Europe, supplying over 100 countries,” she said. Jacopo Fort, Persico, presented a look at the Persico global footprint.

and emphasize care for the environment,” he said. The Orex hybrid machines come in shuttle, carousel, and specialist machines, each designed for a different type of production and product. Frank Harleman, Modelmakerij Hengalo, talked about ‘Automation for Higher Quality and Cost Reduction and Energy Efficiency’. The company manufactures molds for the automotive industry, agricultural equipment, water treatment, medical sector, design products, and game consoles, as well as makes technical refined products for a vast range of industries. The company was founded in 1985, started making rotational molds in 2008, engaged in fully automatic robot production in 2017, and in 2021 began offering fully automatic opening systems. Johan Potargent, AMS Robotics, presented the AMS Robomold and automated box mfg. and highlighted AMS Design, SIM, and OEE and 4.0 software. “Rotomolding is changing. When we joined this organization in 2016, no one was talking about sustainability. Data driven is the most important program for the future. If you want to become sustainable in the future, AMS is capturing all the manufacturing data and plans to go to completely digital.” Dr. Konstantia Asteriadou, Lysis Technologies, talked about sustainability in the graphics industry: thoughts and opportunities. The company’s product portfolio for the rotational molding industry includes labelfree graphics (post- and In-mold); finishing products; improvement products; repair products; and functional and decorative coatings. She defined sustainability as being about making sure that what we use and how we use it today does www.rotoworldmag.com 29

not have negative impact on current and future generation’s ability to live prosperously on this planet. “This is a need, not just a trend,” she said. Dr. Carlos Caro, Kunststoffe, talked about acrylic resin and customizing PMMA for rotational moulding applications. Kunststoffe is part of the GRAFE group of companies located in East Germany. They are a raw material supplier for rotomolding, powder coating, and 3D printing company. They produce PE and PP micro pellets. Their motivation is in the manufacture of highend lighting applications, and glass provides a luxurious look but is too heavy, brittle, and relatively inflexible. PE or PP are low cost, but also low in transparency. “PE specially looks just cheap for those consumers demanding high appearing designed elements,” he said “Polycarbonate provides a better alternative, it looks like glass, has better impact resistance and is lighter. Yellowing is limited to light and weather fastness in outdoor conditions. It is sensitive to any kind of thermal degradation. The rotomolding process must be precise and accurate, and for best results use electrical heated tools instead of using conventional machines with a gas burner,” he said. Lei Wang, Matrix Polymers, talked about research with the University of Portsmouth (the Royal Family Society). “It has been very difficult starting research on PP and post recycled PP,” he said. The main takeaway on PP is that it is not tough enough, but they have achieved some important findings regarding crystallization of the polymer. Roto Rocket’s takeaway was that crystallinity was increased with recycling PP content, which means high stiffness. Crystallinity increased the stiffness and increased the impact strength. John Steele, LyondellBassell, presented a look at the company’s Icorene 1490. He covered the company’s view on sustainability and end customer desires, the story of Icorene 1490, and presented customer examples for the application, PIAT interpretation, technical tests done in the lab with Icorene 1490 12 melt, and CO2 calculations with customers. LyondellBassel is very active in developing sustainability solutions for the plastics industry with their Circulen(R) brand. “You can achieve real savings in CO2 for your company without any machinery investment using Icrorene 1490,” Steele said. Walter Bonazzi, PSI Brand, talked about the automation, robotization, and monitoring of the rotational moulding process. He covered how to connect with customers, the proven methods, and gave some real-world examples. “Track and trace are the future of all manufacturing, and this is growing exponentially,” he said. “Track and trace technology connects the product with the rotomolder and the customer, reduces cost and time, and increases sales and productivity. Venkit Mahadevan, Polimer Link, presented some new-age materials for automotive applications. Polimer Link was founded in 2014 as technical experts in polymer compounding raw material supply for rotational moulding. Headquartered in Malaysia, the company has additional facilities in India and Philippines with a team of over 60 dedicated professionals. “Sustainability challenges in the Asia Pacific region are that it is the epicenter of the world’s mismanaged plastic waste, regulations, and a growing consumer demand,” he said. Sustainable advancements in rotational moulding materials include their PCR and Bio Based grades, challenges and positives, and outlook. He 30 ROTOWORLD® ISSUE 4 • 2023

presented a list of specialty grades the company produces including their HypereneTM Series and Crosslink Series. Gary Lategan, Roto Solutions, talked about ways to make your rotomolding plant sustainable. “You need to promote development that minimizes environmental problems while meeting your required needs and goals today, or as soon as possible, without compromising the quality of the environment for future generations,” he said. “Since rotomolding is reliant on people, he urged molders to employ people with the correct attitude rather than employing cheap labor. Then invest in the best training for your people in every field: materials; moulds; and machines, etc. “A streamlined plant with well trained staff with a good understanding of the process and good equipment will deliver good quality parts on time and every time,” he said. Social and networking events for the conference were generous with an opening reception and several optional outings around the city. The ARMO Gala Dinner was the main highlight as attendees relaxed and enjoyed true Polish culture while a troupe of Polish dancers took the crowd back to an earlier time in Polish history by performing cultural dances in grand costumes. The atmosphere was one of great celebration and fun. There was a pre-conference seminar offered on ‘Controlling Your Cooling to Improve Part Quality and Dimensional Consistency’, presented by Dr. Gareth McDowell, 493K, and Dr. Nick Henwood, Rotomotive. Areas discussed were cooling, where the moulder has the least amount of control, leading to a lack of control and inability to maintain part quality, especially in relation to dimensional tolerances and shape retention. Also discussed were variations in cooling time and how that makes process optimization difficult. Various cooling concepts were demonstrated in real time, using a bench top rotomolding machine.

We Must Come Together to Fix Our Industry’s Challenges The ARMO conference in Poznań, Poland was a success, with 570 attendees from all over the world. As usual the event provided a platform for networking, learning, and sharing of ideas. It was also a great opportunity to showcase the latest technological developments and innovations in the industry. I was not surprised to hear that the theme of the ARMO conference was “Sustainable Rotational Moulding” and that most of the presentations focused on sustainability. This reflected the growing awareness and importance of sustainability in the rotational moulding industry. Many rotomoulders I spoke to wanted to discuss about recycling their products, Post-Consumer Recycle, bio-materials, and reducing energy usage. Just a few years ago topics like these would have been considered fringe subjects, but today they are front and centre in most people’s minds. This is a very positive development, as it shows that the industry is fully committed to reducing its environmental impact. How the world has changed so quickly! It is encouraging news that more and more rotational moulding companies are taking the “Operation Clean Sweep” (OCS) pledge. OCS is an international programme designed to prevent plastic resin loss and help keep our materials out of the marine environment. The OCS programme provides valuable resources and guidelines for companies to follow to minimise plastic pellets and powder loss. This includes things like implementing best practices for handling, storage, and transporting of resin. In addition, it includes conducting regular inspections and clean-ups of production facilities. The fact that polymer suppliers and rotomoulders are taking the OCS pledge is a further sign that the industry is committed to environmental stewardship. It is also a sign that the industry is aware of plastic pollution problems and is taking steps to address them. We are moving in the right direction and is now wider interest in transitioning away from gas-fired ovens. Some moulders have begun to install electrically heated ovens, using renewable electricity. Direct heating of moulds where no oven is required is also a key area of research and development. It is hoped that more affordable solutions will soon be available. Such innovation can help the industry massively improve its energy efficiency and greatly reduce its environmental impact. There is substantial investment happening in the green energy

space. A lot of people are getting interested in rotomoulding hydrogen tanks for transport and energy storage. Rotomoulded tanks which are then filament wound with carbon fibre are lightweight, durable, and corrosion resistant. This is a very positive development for the rotational moulding industry and represents a significant opportunity for growth. Whilst the rotational moulding industry is facing many challenges, it is encouraging to see that many suppliers and moulders are investing heavily and co-operating to create innovative solutions. Sustainability issues are common to all of us and we need to come together as an industry to solve them. I am excited to see how the rotomoulding industry develops in the coming years. We have the potential to be a leader in sustainability in the plastics industry. Our sector has the potential to make a significant contribution to the fight against climate change and the development of a more sustainable economy. Forums like the ARMO conference and similar events held regionally around the world are an essential catalyst to create a more cooperation needed to address the challenges the rotational moulding industry faces. I encourage everyone in our industry to attend and fully support these events whenever possible. By working together, we will create a much more sustainable future for our industry and the planet. www.rotoworldmag.com 31

Award-winning industrial designer eager to embrace rotomolding

Columbus College of Art & Design campus in Columbus, OH.

At the recent Association of Rotational Molders (ARM) annual conference in Kansas City, Connor Thune, a fourth-year industrial design student at the Columbus (Ohio) College of Art & Design (CCAD) was awarded Student Design of the Year for his “RotoPod” outdoor furniture design, as voted upon by conference attendees. Following acceptance of the award, Connor was kind enough to spend some time with me at the conference, and shared his thoughts regarding rotational molding as he prepares to embark on his industrial design career. Design is in the blood. Though a career in industrial design wasn’t an assumed path, Thune’s link to the field is a long-standing family affair. “My father (Greg Thune) is an Associate Professor of Industrial Design at CCAD, after working at a number of industrial design firms prior to joining the academia field,” commented Thune. “As a kid, I remember my dad working on designing cool products in a number of fields: medical, transportation, consumer products… and he traveled globally to observe the products he designed functioning in their end-use applications.” Having been exposed to photographs and anecdotes from his 32 ROTOWORLD® ISSUE 4 • 2023

father’s adventures, Connor Thune realized at an early age his aspiration to “create something, expand my horizons and see the world.” And even though he initially enrolled at Otterbein University (Westerville, OH) as an undeclared major, Thune gravitated quickly to the true area of his calling: the industrial design realm. As part of his industrial design curriculum, Connor received an internship at Radley College in Oxfordshire, UK as a Teaching Assistant. During his 10-month tenure, in addition to teaching Design & Technology courses, he also explored eight additional European countries. “It was a great experience from several perspectives: coach and interact with design students, nurture their skills and impart some wisdom while broadening my personal horizons.” The role of the industrial designer in product development. Though the bridge is still being built between the rotational molding industry and the product design community, Thune clearly sees an active role of the industrial designer in new product development involving manufacturing processes such as rotomolding. “At CCAD, we (industrial design students) are really exposed to a holistic approach to mastering this discipline,” stated Thune.

Connor Thune’s “RotoPod” outdoor furniture was selected as the winner of the Student Design Award.

“Our three industrial design professors all have unique strengths and focuses – we refer to them as ‘the MIND, the HEART, and the HANDS,’ referring to the engineering thought process (MIND), the product aesthetic and user experience (HEART), and the practicality and utility of the product we’re designing (HANDS). This way, we believe we’re getting the best possible training in designing products that are thoroughly engineered, that possess both form and function, and that are human-centric, and make a positive difference for the people using them.” Roto wasn’t readily relevant. Despite building his design credentials via the CCAD curriculum, the international internship and concurrently gaining exposure to numerous manufacturing processes, it wasn’t until relatively recently that rotational molding was closer to top-of-mind when it came to manufacturing platforms. “Honestly, I knew next to nothing about rotomolding prior to enrolling at CCAD,” commented Thune, “and first learned about it through a design competition sponsored by an industry material supplier, WinSell.” The competition focused on the outdoor/backyard space, and

thus the concept for the “RotoPod” lounge furniture design was conceived. Eventually, roto product design became a requirement for CCAD Industrial Design majors, and as a result, Thune and his peers gained more familiarity and mastery with the medium, culminating recently with his “RotoPod” design selected as bestof-show at the Association of Rotational Molders annual meeting in Kansas City. “Obviously, I’m really excited and honored to win the Student Design competition and I’m happy that my design resonated with attendees,” said Thune. “Rotomolding is an ideal platform for this type of product (outdoor/backyard furniture), and I’m currently working on a family of products to complement the ‘RotoPod.’” Influencing the next generation of industrial designers. When considering his relatively recent introduction to the rotational molding process, Thune pondered ways in which emerging product designers could be exposed to roto earlier in their educational experience. “Thinking from rotomolding’s point of view, we need to find a way to increase students’ awareness (of www.rotoworldmag.com 33

X-FACTOR rotomolding) much earlier in their education; even starting at high school, through job fairs, rotomolding facility tours, lunchand-learn sessions, etc.,” opined Thune. “Somehow, we need more outreach so that students are aware of it earlier, and as they enter design school, and then their careers, there’s an established familiarity and confidence in rotomolding as a legitimate means of designing and developing products.” In assessing his personal experience with rotational molding, Thune admits to a lack of first-hand perspective regarding the on-floor manufacturing process. “Practically everything I’ve learned about rotomolding has come from classroom instruction,” commented Thune, “and I know I’ll be better able to connect the dots as I observe the process in action, get my hands dirty and gain a better feel for the manufacturing side of things.” Similarly, he believes up-and-coming industrial designers would greatly benefit from hands-on roto experience: “whatever type of outreach can be built, including on-the-floor observation and participation at rotomolding facilities will be a difference-maker in attracting designers to this process.” Leveraging the advantages of roto. As both Thune’s competence and confidence in designing for rotomolding continue to grow, he’s effectively integrating its inherent advantages in his approach to industrial design. “I view roto as a ‘low barriers to entry’ manufacturing process,” remarked Thune, “based on relatively low start-up costs with tooling, machines, materials, etc. compared to other processes.” He’s also keenly aware of the general public’s perception with plastic and feels the durability of rotomolded products lends itself to a strong sustainability message: “rotomolded products aren’t single-use, throw-away items – they typically last a lifetime and most materials used in rotomolding are recyclable.” Now, as graduation from CCAD looms and a career in

industrial design awaits, Connor feels that with the addition of rotomolding to his design arsenal, he’s better equipped to offer his future clients a broader array of industrial design and development solutions. “I’m really excited about including rotomolding as another tool my design toolbox,” commented Thune. “I see many advantages to the process and lots of untapped market potential to appeal more broadly to the consumer across many segments. Winning the Student Design Award was a great affirmation, and has me pretty stoked to wave the roto flag proudly in my industrial design career.”

Learning all about Finncont in their company introduction

Standing on the edge!

“The success of Rototour 2023 Nordic was truly global, with 37 enthusiastic attendees hailing from diverse corners of the world.” Under the church in Poznań

When I embarked on my journey to explore potential factory sites in March for Rototour, I anticipated a certain level of excitement among potential tour attendees. However, what unfolded surpassed all expectations, revealing the immense interest in the work being done in these countries. After opening bookings on a Friday, I was surprised to find that I had already met the minimum number by the time Monday arrived. The demand continued to soar, and by Wednesday, we had reached our maximum capacity. In a bid to accommodate even more eager participants, I found myself creatively exploring ways to squeeze in additional spots. By Friday, our registration had reached a waitlist-only status. The success of Rototour 2023 Nordic was truly global, with 37 enthusiastic attendees hailing from diverse corners of the world, including Australia, New Zealand, the Philippines, the USA, Canada, Kazakhstan, China, and Brazil.

Iceland Iceland consistently finds its way onto countless bucket lists, drawing people in with the allure of the mesmerising northern lights and its captivating uniqueness. Our visit to Saeplast, however, added an entirely new dimension to our tour experience. Our journey commenced in Akureyri, perched at the pinnacle of Iceland, boasting its beauty alongside the serene fjord. Following a light breakfast, we all eagerly boarded the coach, embarking on our adventure together, setting our course for Saeplast to explore our very first factory. Here we would see a 4.2m machine converted to electric, something unheard of in the parts of the world where we come from. But upon finding out how cheap their electricity was, we were all extremely jealous. Dadi Valdimarsson and Arnar Snorrason were the perfect hosts, answering questions as we toured the facility. As Arnar commented, “It was a great pleasure for us hosting, it is in line www.rotoworldmag.com 37

dinner at one of the region’s premier restaurants. Sunday morning saw us with a 4.30 am departure to make our flight to Helsinki, where we were met by the Brazilians and then continued for a long drive to our accommodation, in preparation for the busy tour days ahead.

with our core values where we want to share, care, and do things together. We noticed high interest about our processes, products, and company and we are simply pleased that people are still “buzzed” after the visit. As you noticed we are not located in the centre of the world, even though we the locals believe it is, so thank you for making the effort to visit Dalvik, appreciated.” Following this, we made a delightful stop at Gisli, Eirikur, Helgi Kaffihús, renowned for serving the finest fish soup and beer bread in all of Iceland. Our journey continued southward, unveiling Iceland’s breathtaking landscapes as we ventured through Trollaskagi and the North West. Along the way, we paused to explore Glaumbær in Skagafjörður, a site steeped in history, housing traditional turf houses and a captivating museum. As we pushed onward to Borgarnes, ominous dark clouds signalled the approach of an impending storm. The coach arrived at our hotel just in time, and the group bore witness to a comical struggle against the fierce wind, with our tour guide, me, and Steve Kyval each taking turns braving the elements. Trying to open the hotel door and usher everyone inside, luggage in tow, amidst the raging wind and rain was an adventure in itself. But such are the joys of being on tour—every challenge turns into a memorable tale. An hour later, undeterred by the weather, we set out once more to savour a traditional dinner right on the water’s edge. Although adverse weather conditions cancelled our initial plans for a glacier tour, we felt no sense of loss. Instead, we bundled up, donned our hard hats and lights, and embarked on an underground adventure into one of Iceland’s longest lava tunnels. This unique experience offered a rare glimpse into the inner workings of a volcanic eruption, as we walked in the footsteps of the lava that flowed during the Leitahraun eruption some 5,200 years ago, situated east of the Bláfjöll mountains. Following this leg of our journey, we paused at a few picturesque locations before reaching Reykjavik, where we would spend our final night in Iceland. The evening was marked by a delightful 38 ROTOWORLD® ISSUE 4 • 2023

Finland Our day kicked off early again as we all gathered on the bus, bound for Inora to reunite with Minna and Matti Aronen, familiar faces from past Rototours. Our arrival was met with a warm welcome, accompanied by a breakfast and an insightful introduction to their factory. We also said goodbye to the partners as they headed off for breakfast with a local school principal and a visit with the children at the school. Thanks to Brad & Deb Smyth for the little koalas that were gifted to them. Inora is a family business with nearly six decades of history, located in Iisalmi. Here, we not only had the liberty to explore their rotomoulding facility but were also treated to an enlightening tour of their other operational processes.

Delicacies at Motoplast Finland

Our journey then took us towards our next destination, with a pit stop for a buffet lunch at a roadside station. While there, we couldn’t resist indulging in some delectable local chocolate, a renowned specialty of Finland. By the time we reboarded the coach, we must have each carried about five blocks, claiming it was for family back home. Our next journey led us to Finncont Oy, a sprawling facility nestled in the picturesque Finnish landscape. Here, we were impressed by the company’s commitment to sustainability, observing the significant strides they are making in this regard. From there, the group journeyed on to Tampere, where we checked into an ultramodern hotel. The hotel’s elevators proved to be quite the drama, but that didn’t deter us from enjoying an

incredible dinner with a breathtaking rooftop view at Periscope, overlooking the city. Tuesday brought a rare opportunity for a leisurely breakfast before we packed our bags and reboarded the coach for our visit to Molok, a factory focused mainly on one product type. I was excited to see the group’s reaction to their machine setup, one of only 5 in the world and something none of us had ever seen before. Add to that a new machine for emptying powder bags and it was hard to pull everyone away. I would have loved to share a photo capturing the sight of a line of rotomoulders, utterly engrossed in watching the machine in action, their jaws figuratively hitting the floor. Following our visit to Molok, we journeyed to Favorit Tuote Oy. Our adventure commenced with a delightful lunch at their head office, a charming and verdant space, oozing with character. The meal was nothing short of delicious and we then walked 40 ROTOWORLD® ISSUE 4 • 2023

over to the factory, where once again the group found themselves mesmerised by the machines. Witnessing such an impressive level of automation in one place, and observing the Robomould in action, was a first for many of us. During this time, our partners embarked on their own unique adventure, indulging in a walking tour, and enjoying lunch at the Kauttua Ironworks and Manor Hotel. The group came together again for the three-hour drive back to Helsinki, where we settled into the charming Hotel Mestari. After checking in, the coach dropped us off at Senate Square. It was here that our friends from Kazakhstan surprised us all with thoughtful gifts, and we took the opportunity to capture a group photo. Following this heartwarming moment, we gathered for dinner, sipping blueberry vodka shots and savouring our first taste of traditional Finnish cuisine, including reindeer. An unforgettable culinary adventure was had by all!

Our final day in Finland began with a tour of Motorol Oy Motoplast, led by the delightful Reijo Strom, who had been our dinner companion the previous night. The entire factory graciously opened its doors to our group, permitting us to take photos, capture videos, and inquire about all aspects of their operations. Following this enlightening tour, two talented chefs treated us to a delectable showcase of local delicacies, providing a memorable tasting experience for all. With our senses still tingling from the culinary delight, we bid farewell to Finland and made our way to the airport, embarking on the next leg of our journey to yet another captivating destination.

and the stunning surrounds. We then descended the mountain and headed to the airport for our brief flight to Bergen. After a busy and tiring week, it was a welcome change to arrive at our hotel in Bergen, being our first multi-night stay of the tour. Our late arrival in Bergen meant a quiet dinner in the hotel and a restful night’s sleep. It was now Friday and our last official Rototour factory was Plastinvent. Their factory is quite small when it comes to rotomoulding but they are doing big things. The entire staff was on hand to answer our questions during the tour, and thoughtful gifts were presented to all attendees upon departure.

Factory Visit with Ovun in Norway

Norway Our Norwegian adventure began with a stop in the picturesque town of Alesund, where we checked into our accommodation before venturing out to a waterfront restaurant, to enjoy some of the local seafood specialties. After dinner, everyone returned to the hotel at their leisure, indulging in the entertainment and scenic vistas that surrounded us. The following morning, we gathered our belongings and jostled for the best seats on the coach, eager to soak in the breathtaking landscapes as we journeyed to Andalsnes. Our partners dropped us off at Ovun for an insightful factory tour, while they set off for a morning tea at Trollveggen. Ovun were excellent hosts, offering coffee and biscuits before guiding us into the presentation room. Attendees enjoyed the factory tour, witnessing a range of intriguing and innovative products in the process. The highlight came as we stepped outside for a group photo, set against one of the most breathtaking backdrops any rotational moulding business could hope for. Our partners rejoined us, and we made our way to the mountain peak using the Romsdal gondola. At the summit, we enjoyed lunch with a 360-degree view, taking in the majestic peaks

We then returned to the city and some were interested in a leisurely walking tour, before we all gathered for lunch, trying out the Bergen Plank. Tickets were provided for those who wished to take the Mount Floien Funicular, offering spectacular panoramic views. The remainder of the afternoon was left to personal choices - shopping, conducting business, or simply resting. Friday night marked our final formal group dinner at Bryggen Tracteursted, a historic building dating back to 1708. We were treated to captivating tales by a local storyteller before indulging in a delicious meal and the opportunity to sample aquavit, a locally distilled spirit. Saturday greeted us with a sense of anticipation, as we readied ourselves for a day of sightseeing during our lengthy journey back to Oslo. It marked the final leg of our coach travels and was well worth the ride. The road from Bergen to Gudvangen unfurled before us, offering spectacular vistas of lush valleys, towering peaks, and cascading waterfalls. Our coach expertly navigated winding roads, unveiling postcard-perfect landscapes around every bend. Our knowledgeable guide enriched the experience with captivating tales of Norwegian history, culture, and the natural wonders that surrounded us. www.rotoworldmag.com 41

Upon reaching Gudvangen, our excitement soared as we boarded the Nærøyfjord cruise. This specially designed vessel allowed us to fully immerse ourselves in the breathtaking splendour of the fjord. As we glided through the narrow waters, hemmed in by towering cliffs that seemed to touch the sky, we were humbled by the raw and untamed nature enveloping us. Our voyage concluded in the charming village of Flåm, where the Ægir Viking Restaurant beckoned us with a Viking plank - a gastronomic adventure featuring five tasting courses thoughtfully paired with five local beers. The itinerary indicated a photo stop at Stegastein, but none of us anticipated the adventurous journey up the mountain on a singlelane road, all aboard a massive coach. Thanks to our skilled coach driver, we safely reached the Stegastein viewpoint—an architectural marvel jutting out from the mountain, treating us to breathtaking vistas of the Aurlandsfjord below. As we prepared to depart, our resident tour thrill-seeker, Tim Leed, decided to run down the mountain and rendezvous with us at the bottom. To our amazement, he accomplished the feat, arriving simultaneously with our coach. Our onward journey to Oslo included a stop at the Borgund Stavechurch, a remarkably preserved wooden church dating back to the 12th century. Although it was a late arrival at our airport hotel, it marked the moment where we bid farewell to some of the tour participants before proceeding to the ARMO Conference in Poznań.

Poland After checking in to our hotel in Poznań, we all gathered for the Welcome Reception, and the day culminated in a dinner where the entire group was graciously hosted by Matrix Polymers. A big thank you to Martin Coles and their team! While I won’t delve extensively into the conference proceedings, as there will likely be an article about it in this issue, we did have a few more Rototour events to look forward to. The conference concluded on Tuesday afternoon, and that evening, the group came together for one final activity – a “Taste of Poland” food tour. Our guide, dressed in traditional attire, made the experience exceptional and entertaining. He introduced us to Poznań’s famous goats at Town Hall, showcased the exterior of Przemysl Castle, and guided us to the stunning baroque parish church. At three different locations, we had the pleasure of sampling traditional Poznań dishes, enjoying both food and drinks. The following day was marked by more goodbyes, and then the rest of us boarded the bus for our very last factory tour at Kingspan Water & Energy So. Z.o.o. They greeted us with a generous spread and conducted an exceptionally professional tour, highlighting their developments in innovation and environmental sustainability. Before I conclude, I would like to express our heartfelt gratitude to all the factories that hosted our group. We genuinely cherished our time with you and greatly appreciate your effort and openness

Will Smart Glasses change how people use social media? Kim Harrison, Cutting Edge PR

Smart glasses are a fascinating concept. As far back as the 20th century, science fiction and literature imagined a world where wearable technology could enhance our quality of life. Now we see smart glasses available in the retail market with a range of augmented reality (AR) features included. Such features usually mean one of the lenses of glasses can recreate screens and features you see on your smartphone, like navigation for maps, flashing up notifications to you about traffic, or text messages and some web content, plus music or video content. Communication professionals will be able to record impromptu video content from presentations and meetings at all organizational levels and use some of this in storytelling activities for employees and for social media. Thanks to the endless possibilities of this advanced wearable tech, the market for smart glasses has skyrocketed and will continue to grow in the next few years. A report on the global smart glasses market by ReportLinker notes that the market was valued at USD219 million (AUD348 million) in 2022, and will grow at a rate of 9.5% through 2028. Younger generations have been driving the market, interested in this cuttingedge tech with diverse applications and uses. Today, smart devices are mainly used to connect on social media, and the latest string of smart glasses is incorporating features that build on that interconnectedness – not only with the other devices in a consumer’s 44 ROTOWORLD® ISSUE 4 • 2023

LEADERSHIP ecosystem but with the broader community around them. Our article on “Six Rules for Using Social Media in Marketing Communication” outlined the need for brands to cultivate meaningful relationships with audiences. Communication professionals and company leaders can prepare for this demographic shift towards more immersive smart wearables by understanding their potential applications in social media use. The advent of smart glasses Smart glasses come equipped with capabilities similar to that of a smartphone or computer, from image and video capturing to voice detection, commands, and more. Legacy tech juggernauts like Google and Meta have led the charge, but the world is also seeing sleeker versions from fashion-forward companies. Of all the major designer brands, Ray-Ban sunglasses were among the first to upgrade to smart technology. The Original Wayfarer Classic was one of the first models to move away from metal and sport an acetate frame, and the silhouette has been well-loved since 1952. Today, it’s been modernized via a partnership with Meta to include a 12 MP camera and social media live-streaming capabilities. This changes the game for on-the-go documentation, both for consumers who want to keep their hands free to enjoy their day and for busy PR pros covering events.

Pushing boundaries The world was introduced to mainstream augmented reality (AR) models in recent years, but modern AR devices have already spurred interest about their implications in daily life. People have enjoyed AR through social media filters and multiplayer games like Pokémon GO, but the proliferation of smart glasses has opened up more practical applications. The TCL RayNeo X2 AR glasses give users access to an even wider world of social media that transcends languages. While a user reads a post or listens to a video in another language, it can translate visual text and display subtitles from several languages in real-time. This allows users to get deeper context on global issues and trends – and could be a valuable analysis tool for PR professionals conducting market research, gathering feedback from international consumers, and more. As technology advances, smart glasses may become as invaluable to the general public as smartphones, especially as AR, AI, and VR revolutionize social media use. Alert communicators and leaders can capitalize on these developments to use in their professional role. Exciting possibilities ahead!

Bushman was very pleased with the conference. “Attendees were all smiles and the vibe was positive throughout,” he said. “The conference showcased an amazing future for the rotomolding industry due to many technical advancements including simulation and automation.”

Bushman reported the organization is now 150 molders strong and this is in large part due to the strong education and training programs ARM provides its members. “Molders are now able to become Certified Operators through ARM’s Online Operator Certification Training program, which is huge advancement for the rotomolding community.” Best-selling author and speaker Chad Hymas was the keynote speaker for the event. Hymas’ talk was focused on leaving a legacy and change. Through his own inspiring story, Hymas moved the audience and clearly touched hearts. In 2001, at age 27, Chad’s life changed when a 2,000-pound bale of hay shattered his neck, leaving him quadriplegic. Chad’s dreams were not paralyzed that day, and he became an example of what is possible. He urged attendees to, “Make today about someone else.

bountiful, live with intention, and don’t wait for the bus!” Gareth McDowell, PhD, and owner of 493K, presented some scientific approaches to rotomolding. Covering process parameters and quality checks, McDowell worked through each important area of roto processing. He provided an overview of what a molder can measure in their roto plant to ensure quality targets are being met. “If you can see pinholes on the outside of your mold, you will definitely see them on the inside of your mold,” he said. Lisa Greentree, Wittmann Canada, presented a 3 successful resin automation case studies. “Resin automation can help improve your roto facility from off the shelf one color solutions to complex multi-color systems,” she said. “The automated system will be cleaner, there will be less handling, and it will require less time and handling.” Denis Rodrique, Univeristé Laval, presented some preliminary results on recycling crosslink research funded by the Crawford Education and Development Foundation. The Draft National Strategy to prevent plastic pollution aims to identify actions needed to eliminate the release of plastic waste from the environment by 2040. This strategy aligns with and supports EPA’s National Recycling Goal to increase the U.S. 48 ROTOWORLD® ISSUE 4 • 2023

recycling rate to 50% by 2030. “8.3 billion tons of plastic waste is generated globally (according to the EPA),” stated Rorique. Of that 6.3 billion tons are used only one time and end up in landfills. Canadians produce 3.3 million tons and 2.8 end up in landfills. This value is expected to increase by 10% by 2025. “XPLE has great potential to be used in several plastics’ applications. There are various techniques available to crosslink and de-crosslink PE or any other polymer. More research is needed to develop new and optimized techniques for both steps. Recycling of all plastics is important, but still very limited,” he said. Mark Kearns, Queen’s University Belfast, gave an in-depth look at ongoing studies that aim to improve the understanding of the rotational molding process through modelling, shrinkage, and warpage. Simulation and modelling use at Queens includes hydrogen storage tank development, moulded-in insert design, and simulation to predict part shrinkage, and warpage. This important research continues regarding prediction of shrinkage and warpage under different cooling methods, validation of

simulation results, application of different polymer materials and muti-layer, and simulation models applied to industrial designs. Perc Pineda, Chief Economist of the Plastics Industry Association, gave in insightful overview of the current state of the plastics industry. “88% of plastics ended up in personal consumption,” Pineda said. The headwinds for the industry are higher cost of capital, weaker household spending, uneven economic adjustments across industries, and inventory and capacity adjustments. However, the tailwinds, are a strong labor market, reshoring, friend-shoring, insourcing in the mid-term, stable healthcare, and consumer essentials demand. Spillover effects of AI on end markets in the long-term. He said the US industry is slowing but persistent. In 2024, despite a resilient 2023, we will need to be concerned about possible recession. This, as we face higher costs for capital and reduced household spending.

ethylene market balance is tightening, global PE oversupply will lead to both strategic and tactical actions, and current margins are insufficient to support a sustainability investment expectation. “Polyethylene has entered a period of lower margins than we have seen over the past decade,” he said. “The expectation is that producers will invest in sustainability.” Pineda and Gick participated in a discussion forum and talked about the industry forecast. Pineda said he remains bullish for the manufacturing sector. Gick said people are concluding that prices are going to be higher for a while. Former FBI agent and author of The Secret to Cyber Security, Scott Augenbaum, talked about cyber security and protecting yourself and your family. “The secret is that most cybercrime could be avoided. Almost 90% of cyber-attacks are caused by human error behavior,” he said. This is a $10 trillion dollar per year issue and the cyber-criminals seeks to steal your money, steal sensitive information, and wreak havoc. Today the global cybercrime damage costs are $6 trillion USD per year. The estimated costs of cybercrime will have increased by 23.84% from 2016 to 2022, according to Augenbaum. He advocated for the use of a

2-factor authentication system, and presented four truths about cybersecurity: 1)None of his victims ever expected to be a victim; 2) Once the cybercriminals do their damage, the chances of law enforcement getting your money or data returned is difficult; 3) The chances of law enforcement bringing the cybercriminals to justice is extremely challenging; and 4) Most cybercrime victimization could have been prevented. Tom Innis, Xcelerant Growth Partners, demonstrated the benefits his company provides from effective product design, development, and marketing, to product launch. Innis shared a client case study featuring the Frozen Labs Cold Plunge Tub vs other market offerings. The design-for-process optimized this product in cost and manufacturing repeatability. The product checked all the boxes relative to specific market positioning objectives, and product launch timing exceeded original expectations by completing the product in 60 days from the onset of design to tool build. Dru Laws, Brigham Young University Idaho, presented a close look at the 2022 ARM Product of the Year won by Tango Manufacturing. The winning product was Halltech’s rotomolded XLPE Filter Box. Tango is a sister company to Titan Fuel Tanks located in Idaho Falls, Idaho. The company is engaged in custom manufacturing, specializing in XLPE molding and assembly of aftermarket car parts. They employ a Ferry 4600 molding machine, 3D scanning, CAD modeling, and 3D printing. Halltech is the leader in aftermarket cold air intakes for Corvettes.They teamed up with Titan/Tango in developing the C8 product. The part includes a stainless back plate, thermoformed cover, and custom filter. Jim Crawshaw, PSI Brand, talked about ways rotomolders can take advantage of plastic tracking methods. He shared how track and trace provides cost, resource, and productivity advantages. Barcodes create ease and speed and improve accuracy and inventory control. QR codes track and trace manufacturing products and deliver instructions to customers. And RFID (radio frequency identification) is good for anti-theft, security cards, waste disposal, and vehicle tolls. Sergio Zilioli, Persico, gave a short history of Persico, and featured their work on hydrogen liners. “This is a new era for the rotomolding industry,” he said. He discussed the potential and related challenges for this market from a manufacturing perspective. Dustin Turgeon, NOVA Chemicals, talked about understanding success with recycled solutions in rotomolding. “True postconsumer resin is hard to find,” he said. “Most recycled polyethylene on the market today comes from flexible or milk jug sources.” Turgeon discussed the technical aspects of incorporating flexible recycled polyethylene into rotomolded products. rPE incorporation in rotomolded parts creates new opportunities for a circular plastics economy. Turgeon recommended working with your supplier to optimize the process and properties. ARM Annual Business Lunch ARM Committee Chairs gave reports.

REPORT Ask Dr. Nick: Is it possible to Rotomold TPE? Dr. Nick: The term “thermoplastic elastomers”, or TPE’s, covers a range of different materials, using a number of different chemistries. According to ISO 18064, there are six generic classes of commercial TPE’s, together with one unclassified category: • Styrenic block copolymers, TPS • Thermoplastic polyolefin elastomers, TPO • Thermoplastic vulcanizates, TPV • Thermoplastic polyurethanes, TPU • Thermoplastic copolyesters, TPC • Thermoplastic polyamides, TPA • Unclassified thermoplastic elastomers, TPZ Some TPE’s will be made directly in a reactor (“copolymers”) and some will be made from a physical mix of polymers (usually a plastic and a rubber). Probably, some types of TPE will be rotomoldable and some will not. I have had success rotomolding TPO’s (thermoplastic polyolefin elastomers), which are essentially extremely low density polyethylene. They can be used to make a part with reasonable stiffness and fantastic recovery properties; the part can be subjected to massive deflection, but substantially recover its shape once released. Some commercial applications are road barriers, boat fenders, and furniture. In terms of whether a particular TPE will be rotomoldable, here are the main issues that will need to be considered: • The inherent flexibility of the material will most likely make it difficult to pulverize into a powder. Using the normal type of ambient system is unlikely to be successful; the material may need to be cryogenically ground. This can be done, but it’s significantly more expensive. • A key factor with any material is whether it has acceptable viscosity characteristics when melted. Unlike other processes, rotomolding takes place under zero shear conditions. We rely of the melt viscosity being sufficiently high to allow melting powder particles to fuse together, without us applying additional force or pressure. Initially this can be assessed by modified MI measurements. The other way is to simply try to rotomold a sample. • Watch out for unusually high melting points. Linear branched PE’s, which we commonly use in roto, melt at around 250°F and need to be raised to approx. 400°F to cure properly. If your new material melts at a substantially higher temperature, you may start degrading it before it can be correctly cured. In any event, heat degradation should be carefully considered. Roto grades need substantially more antioxidants to protect them, because of the relatively long cook times that we use. I’ve found that the usual phosphite / hindered phenolic additives we use in PE are often effective for other types of polymer, so this may be just a question of getting some advice from an additive 54 ROTOWORLD® ISSUE 4 • 2023

supplier or compound formulator. TPE’s that incorporate a rubber component may have an extra susceptibility to heat degradation, especially if they utilize polybutadiene rubbers. Whilst considering additives, you will also need to be mindful of UV stability, especially for outdoor applications. A practical alternative could be to start off with a compounded black material. My experience with TPO’s was that, unsurprisingly, they exhibited much lower shrinkage than standard PE’s. Whilst this is potentially an attractive feature, your part design should take account of this and the mold may need to be multi-sectional in order to be able to extract the part at the end of the cycle. You may also need to experiment with different mold releases; some types of TPE can be very sticky and difficult to release compared to polyethene. Finally, don’t expect the TPE material supplier to know much, if anything, about rotomolding requirements. As an industry, we suffer from being a niche market! Please don’t be discouraged from pursuing your customer’s request. Finding new material options that we can rotomold is essential to sustaining growth in our industry. One day we may run out of products to make from polyethylene, much as we all love it as a material!

The Use of Simulation in the Development of Hydrogen Storage Vessels Alex J. Pritchard, Mark P. McCourt, Peter J. Martin, and Mark P. Kearns Polymer Processing Research Centre, School of Mechanical & Aerospace Engineering, Queen’s University Belfast, Northern Ireland The need for long-term energy security combined with a desire to have cleaner solutions that do not contribute to global warming has resulted in Hydrogen being discussed as a potentially important energy vector. With advances in technology, and a much wider interest for storage vessels, there is an opportunity for the rotomoulding industry to diversify their product offerings into new markets. Type IV hydrogen tanks, typically used for transportable tanks used in cars, buses, trains, etc. are made up of three major components. A composite reinforcement, a polymer liner, and metal bosses to allow gas management systems to be attached to the tank (see Figure 1).

Figure 1: Schematic detailing the common components of a Type IV hydrogen storage vessel

Hydrogen storage tanks are challenging applications to manufacture using the rotational moulding process. When doing so, it is important to consider the gas permeation properties of the liner, the thickness, and the encapsulation of the boss within the liner to prevent gas from escaping. As part of a wider project working towards the development of a complete prototype 350 Bar Type IV storage vessel, the team at Queen’s University Belfast (QUB), in collaboration with their industrial partners Kingspan Water and Energy, CCP Gransden, B9 Energy, and academic partner South West College, hope to explore and resolve some these challenges. Development of Boss & Liner Liner development in this project makes use of the AMS electrically heated and robotically controlled moulding system installed at QUB, as shown in Figure 2. This technology has a number of advantages over a forced air oven to ensure that the liner can be repeatedly produced within the desired specification. The main advantage with an electrically heated tool is that it provides a much higher control over the heat application during 56 ROTOWORLD® ISSUE 4 • 2023

the moulding process, allowing the thickness, sintering, and densification of the tank liner to be controlled accurately in local regions of the moulding[1]. This is important for hydrogen tank liners, as a minimum thickness is required to ensure the allowable gas permeation rate from the tank safety standard is achieved.

Figure 2: Advanced rotational moulding automation cell at QUB

The most challenging aspect of moulding tank liners is the encapsulation of the metallic bosses within the polymer liner (see Figure 3). Adequate encapsulation is vitally important as these parts pose a potential hydrogen leak path if the liner material separates from the metallic boss. A poorly designed boss can also lead to localised overloading of the laminate and can contribute to tank failure. In order to understand how various design elements contribute to the performance of a boss, the project has made use of modelling and simulation. To do this, CAD geometry of the constituent boss, linear, and composite components are modelled under pressure using the simulation package ANSYS. The design optimisation tools within ANSYS can be employed to identify the effect of various design elements on the performance of the design under load. Figure 3 shows the stress distribution of an optimised boss design, where ANSYS controlled and optimised the size and shape of the castellations as well as the overall diameter of the boss. The objective in this case was to minimise the maximum stress value in the boss component while minimising weight at the same time. While the simulation approach has proven to be effective for producing strong and light weight designs, it is not able to replace

Development of the Overwrapped Tank Filament winding is a technique for manufacturing open cylinders and closed end structures such as tanks. Other examples of products produced using filament winding include: pipes, golf

the experience of a rotomoulder! Therefore, the project has also made use of rapid prototyping tools to print the boss designs in high temperature resins, making them suitable for moulding trials[2]. The printed parts shown in Figure 4 enable observations of the moulding behaviour of each design to be made. From the successes of the high temperature resin parts, the project also investigated the use of metal printing as means of manufacturing boss components that more closely reflect the heat transfer of a machined boss, as shown in Figure 6. The primary advantage of both of these methods is the cost savings over the machining of the components from solid billets of material. However, this is not the only advantage. The resin printed bosses are opaque and can be illuminated quite easily within the mould, as shown in Figure 5A. Making use of this, a unique inspection tool was developed to allow monitoring of the moulding in of the printed boss designs using the electrically heated tooling (see Figure 5B). Building on previous research work, it is hoped that this will aid in developing the simulation capabilities further by observing the real-time encapsulation behaviour of these large components [3, 4].

club shafts, oars, bicycle rims and forks, missile casings, aircraft fuselages, lamp posts, and yacht spars. For this reason, it has become the leading technique for manufacturing hydrogen pressure vessels. The process involves winding fibres (usually glass or carbon) under tension around a rotating mandrel, which is the rotationally moulded tank liner with a boss on each end to form a Type IV hydrogen tanks. While the liner rotates about a spindle, a delivery head moves back and forth horizontally in line with www.rotoworldmag.com 57

the rotating axis, laying down the fibres onto the rotating liner in a desired angle to the rotational axis. The fibres can be either wet wound, where they are impregnated with resin (the matrix) by passing through a bath as they are wound, or dry wound, using a pre-impregnated fibre known as tow-preg. Once the liner is completely covered to the desired thickness, the resin is cured either in an autoclave, an oven, or rotated under radiant heaters. In general, there are two types of winding patterns, known as hoop and helical windings, as shown in Figure 7. High angle hoop windings are used to provide circumferential strength to the tank, while lower angle helical windings provide greater longitudinal/ axial strength. The major cost in hydrogen tank manufacturing comes from the carbon fibre layer, and hence there is lots of research focus dedicated to understanding how to optimise and reduce its use. In addition to the materials used to wind the tank, the winding angle is of upmost importance to the strength and ultimately the failure behaviour of the tank[5,6]. For example, during bursting it is important to ensure that the failure is concentrated in the mid-section of the tank, thereby ensuring that the metal boss components do not become projectiles if the tank were to burst[7]. The design, analysis and fabrication of wound pressure vessels is a complex task for the following reasons:

uncovered during winding, thereby minimising material waste. From this point the material and stacking sequence (the number and order of hoop and helical windings) can be optimised. This is done within ANSYS. Figure 8 shows an example of the fibre directions for a single layer of hoop and helical winding on a tank liner within ANSYS. Once the composite layer is setup, the mechanical loading and boundary conditions (such as how the tank is held in place) can be applied and the results analysed. Figure 9 shows a cross-section of a tank laminate illustrating how the stress is distributed through the composite as result of the winding angles and material properties.

Figure 9: Cross-section illustration of stress distribution in the laminate of a tank at 350 Bar pressure

Figure 7: Schematic illustrating the difference between (A) Hoop and (B) Helical winding angle

Determining the ideal helical winding angle for a filament wound pressure vessel requires consideration of various factors, including the mechanical properties of the materials, the liner geometry, and the performance requirements of the tank. In this project, the filament winding simulation software ComposiCAD was used to identify the appropriate winding angle based on factors such as the diameter of the boss at the end of the liner. The optimal helical winding angle is selected based on the polar opening size, which naturally leaves the boss area of the liner 58 ROTOWORLD® ISSUE 4 • 2023

Once the model has been established, there are a number of useful tools within ANSYS to optimise the boss, liner, and composite design. After the tank designer defines the basic boundary conditions and limits, ANSYS will optimise the design using machine-based learning. Conclusions & Future Work This is an exciting application for rotational moulding, and its flexibility and low initial outlay cost in comparison to other moulding processes makes it ideal for prototyping hydrogen tank liners. Rotational moulding is also ideal for smaller batches of tanks for more unique applications being produced using the process. The Centre for Advanced Sustainable Energy project will continue until the end of the summer 2023.

MiDesk – Education for All According to UNESCO, in terms of money spent and people involved, education is far and away the biggest industry in developing countries. School building accounts for a substantial part of this total investment and school furniture represents about 10-20% of the cost of school building. UNESCO studies have found that sufficiently designed furniture is an essential factor in the development of the capabilities of school children. UNESCO also identified the school furniture problem would only be solved by innovation. Experience has demonstrated that furniture should not be thought of simply as “pieces of furniture,” but thought of in a larger context of fulfilling the needs of the school and the student. Functional literacy — the ability to read and write — is almost impossible to achieve without a dedicated writing surface — a school desk. In mid-2000’s there was the introduction of a flat sheet of rigid plastic, which children could use as a simple writing surface. 60 ROTOWORLD® ISSUE 4 • 2023

This ‘lap desk’ was produced as a very quick and cheap answer to the writing surface shortage crisis experienced in schools in developing countries. Today, there is a truly innovative South African solution available, providing underprivileged children, who don’t have desks, to attend schools with portable desks. The portable desk, which includes a chair, can be wheeled to and from school and has a solar light and USB charging port attached to it. MiDesk is more than just a writing surface. It fulfills the needs of students both at school and home. The portable desk costs about USD100 and can last for the 12-year duration of schooling. MiDesk actually started out as a high school science project for Talita Boodhram when she was 16 years old. She was watching the TV news and a story about children that did not have desks at school and were writing on cold concrete floors. This was when she identified the need for MiDesk. In South Africa alone,

according to UNESCO, there were 3 million children at school without desks. Talita built the first MiDesk prototype out of cat litter boxes and beach spades. Fast forward 5 years and Talita is now MiDesk Global marketing head. Talita holds a degree in Management Studies and a Postgraduate Diploma in Entrepreneurship from The University of Cape Town. She was awarded The Anthony Hill Award for building the best Genesis Brand in her degree and was the winner of the best pitch at the UCT Women in Entrepreneurship Expo. Her mother, Farana Boodhram, converted the idea into production, creating MiDesk Global, which has produced over 4,000 desks to date. Farana has over 20 years leadership expertise as business founder, owner, CEO, and managing director of two thriving companies, specializing in mining and logistics and sustainable development. MiDesk Global is supported by doner funding through corporate social responsibility programmes, non-governmental organisations, and government agencies who operate in South Africa. Old Mutual is the oldest insurance company in South Africa. On World Literacy Day (8 September) they made the first of 6 donations that aims to improve the education of 400 children from schools in the North West and Eastern Cape identified by the Nelson Mandela Children’s Fund. “As a responsible business, we seek opportunities to deliver cuttingedge Corporate Social Investments that contribute to inclusive, transformative, impactful, and sustainable socioeconomic development in the communities where we operate,” said Antonia Oakes, Retail Executive of Customer Experience and Responsible Business at Old Mutual Insure. The MiDesk revolutionary wheelie schoolbag provides as child with a chair to sit on and a desk to write on that can be used at home and school. No matter where they are, they have a tool to assist their learning process. With added features such as the solar light and USB charging portal, reflective stickers for visibility at night and ruggedized wheels for rural terrains, the MiDesk provides a complete solution to a child at school and home. Homework becomes a challenge for families who cannot afford the luxury of having a furniture table to write on. The solar light is a small but important feature allowing homework to be undertaken even when mains power is cut at night. In mid-2023 the British High Commission (Pretoria) donated 150 MiDesks to children at Goza Primary school in Soweto following concerns about the impact which increasing electricity load shedding has on the learning ability of children to study at home. Pioneer Plastics has been manufacturing in South Africa for over 40 years. They have 3 Reinhardt carousels, a Rotoline shuttle, and a Persico SMART machine. They have also won the ARMSA Product of the Year for 8 years in a row. They were www.rotoworldmag.com 61

the logical manufacturing partner for MiDesk to work with to convert Talita’s design ideas into rotomoulding reality. Pioneer have in-house CNC machines and experienced metal workers to manufacture custom moulds in sheet metal or aluminium. Their motto is ‘Anything is possible’. Pioneer Plastics quickly determined that rotomoulding was the only cost-effective way to manufacture the portable desk. A rotomoulded polyethylene solution delivered excellent impact strength, good wall thickness, and the puncture resistance needed to withstand the tough operating conditions, both at school and when wheeled home. The ability to economically mould small production batches in customised colours to suit corporate doners was also ideally suited to the roto process. MiDesk is moulded from 3 separate fabricated mild steel moulds, with metal handles and axle fabricated in-house by Pioneer. The rest of the components are sourced from third parties and are all assembled by Pioneer at their Pretoria facility. The portable desk will go a long way to ensuring a better education for school students in developing countries. MiDesk provides a child with a chair to sit on and a desk to write on that can be used at home and school. No matter where they are, they have a tool to assist their learning process. Rotational moulding continues to be a process when well executed, and presented superbly well, offers fantastic possibilities all around the world.

PRACTICAL ROTO TIPS R. Dru Laws, Brigham Young University - Idaho

5 Practical Mold Release Tips If mold release was understood, purchased, stored, transferred, and applied correctly, you’d likely use less release tomorrow than you did yesterday, and you’d mold better parts in the process. Everyone wins! Below are 5 tips to help you get started on this moneysaving, quality-improving journey. TIP #1: Know Your Release type. Mold release comes in a variety of forms, but they are typically classified into one of the following 3 categories: a) At one end of the spectrum are sacrificial mold releases. These are not very effective and are intended to be reapplied after every part. We do not use these in rotational molding. b) At the other end of the spectrum are permanent mold releases. These are applied to the mold surface only once because they work so well (too well in many cases). Teflon coated molds fall into this category. c) And in the middle of the spectrum is what most molders are buying in our industry. These are called semi-permanent mold releases. When done correctly, they are applied to new molds initially, then reapplied as needed during production. Historically these were solvent-based liquids, but more and more suppliers are transitioning to water-based formulas nowadays. TIP #2: Reduce Your Release Quantity. A mold release expert recently commented that they can tell when their customer finally figures out semi-permanent mold release because they start buying half as much. This confirmed what I often tell molders when I teach the Roto101 course around the world…“most molders probably buy twice as much mold release as they should be buying”. This is due to one or more of the following reasons: • The operator thinks that more is better, so they simply use too much. • The operator isn’t using the most efficient method to get mold release to the mold surface. • The semi-permanent mold release is being used as a sacrificial mold release and being applied to often (because it is being applied incorrectly). TIP #3: Change Your Release Perspective. A better understanding of mold release requires a complete change in perspective on what it is meant to do. Oddly enough, the primary purpose of mold release is NOT to get your molded part released from the mold. In fact, that isn’t even the secondary purpose of mold release. 64 ROTOWORLD® ISSUE 4 • 2023

1. The main purpose of mold release is to protect your mold. Without some layer of protection, your expensive mold surface can be compromised by the inexpensive plastic you are molding. 2. After protecting your mold, the next priority for mold release should be to keep your part in contact with the mold for as long as possible. My opinion of mold release changed drastically when a resin supplier taught me that mold release is best described as “controlled adhesion”. Since then, I have often wished I was influential enough to rebrand the entire industry. Mold release techniques improve significantly when you start thinking of them as techniques to promote adhesion for a little longer in your cycle. The longer your part stays in contact with your mold, the better control you will have over the longterm dimensional stability of your part. Many have heard me compare mold release to a high-quality bandage …. you want it to stick until you don’t want it to stick. The same is true for mold release. TIP #4: Understand Your Release Formula. If you are wondering how much mold release is necessary, the best answer is usually “less is more”. This is particularly true if you can apply it to your mold the best way possible. This makes a lot of sense when you realize that mold release is only about 2-10% solids suspended in 90-98% water. The manufacturers of these products do their best to keep the solids suspended in the water, but there is some settling that will typically occur. In fact, most mold release containers have a reminder note to shake before using. This is something worth remembering as you consider what containers you are using for storage and usage. For instance, if you buy your mold release in 55-gallon containers, are you doing anything to agitate the contents before dispensing it into smaller containers? If not, you may initially be pumping out a mixture that has far more than the 2-10% solids when the drum is new, and pumping out only water by the time the drum is closer to empty. This will certainly lead to inconsistencies in mold release application. When moving mold release from one container to another, it’s always best to agitate or shake or otherwise mix the contents first, thus maintaining the critical solids-to-water ratio mentioned earlier. This is also true immediately before applying the release to the tool…give the container a quick shake before applying. TIP #5: Improve Your Release Application Well then, what is the best way to actually get the solids of the mold release onto the mold? Using a rag for mold release is rarely preferred. Depending on the fabric, it may soak up the water carrier and apply too much of the solids on your mold, while other

materials will trap the solids and apply just the water on your molds. Although a bit ridiculous, my best recommendation comes in the form of a silly comparison. If I were to need a paint job on my car, would I be satisfied if it was done using a squirt bottle and/or a rag? Absolutely not! The results would be terrible for sure. I would expect the person performing the task to use equipment that provided the best material distribution. Many of the molds we use cost as much as a car, and we allow the use of inferior application methods to paint them each day with mold release. Why do this when a far superior method exists, the use of which pays for itself in the reduction of consumed mold release? An HVLP gun (high volume, low pressure) is arguably the most effective and consistent way to apply most release. Don’t forget to agitate any mixture before adding it to the gun, and again before using the gun. • This method deposits all the release right where you want it. • The designed solids-to-water ratio is always maintained. • Every ounce of release you purchase is utilized. • This method requires less material to achieve the same result. Pictured above is a Spectrum brand HVLP gun that costs about $200. For a few additional dollars, you can replace the gravity feed canister with a bladder insert that allows you to apply mold release with the gun at any angle (even upside down).

I was encouraged long ago to switch to an HVLP gun, but hesitated due to the cost associated with numerous guns. I had multiple mold releases used on multiple machines. Years later at a different location with only one machine and one release, I finally made the purchase. Within days I regretted not making the switch all those years earlier. If I knew then what I know now, I wouldn’t hesitate to purchase dozens of these HVLP guns in a single facility if needed.

NEWS ASSOCIATION OF ROTATIONAL MOULDERS AUSTRALASIA INC. • ARMA

President’s Report 2023 – Chris Glenn The past year has been outstanding, with our Association in a vibrant and strong position. This was on full display at the recent conference in Queenstown. Our vision as an Association is to represent the interests of our members, and the rotational moulding industry, with passion and professionalism. This has been achieved by providing our members with real benefits that assist them in their business every day, through training, templates, codes, advice, referrals, or relationships both locally and internationally. Over the course of the past year, we have held conferences in Melbourne and Queenstown, developed our strategic plan and the Clean Sweep partnership, and our CEO Michelle Rose has made many visits to members at their workplace. These major initiatives, along with other activities, such as theASNZS4766:202 standards amendments, Length of Service Awards, and restarting of the Icon Of Rotomoulding Award have ensured that we, as an industry, continue to prosper and grow. The Queenstown conference particularly highlighted the large number of new opportunities available to the rotomoulding industry, from renewable energy through to automated rotomoulding, and an ongoing improvement in the professionalism of our staff and workplaces. Certainly, this is an exciting period for our industry.

The ARMA Board had several changes over the past year, with Anant Yuvarajah and Grant Palling stepping down. I would like to thank them both for their contribution and support. Joining the Board were Varum Chand (our first Pacific Islands Board member), Brad Smyth, Ben Hopley, and Andrew Currie. I would like to make a special mention of Graeme Hall who has spent 11 years on the Board and has stepped down, having served in all major Board positions during this period. His impact and insight have been missed. I would like to thank and acknowledge our new Board members, along with our ongoing members Ian Gough, Trudi Duncan, (our immediate Past President), Mark Meadow, Karen Durkin and Kate McKie for their support and very important contributions, both to ARMA and the Board. The Professional Team The ARMA team of Petro Geldenhuys (NZ), Zoe Perrington (Membership & Admin), Andrea Glenister (Bookkeeper) and Karly Gniel (Conference) lead by Michelle Rose, our CEO. With our achievements and plans we have a great platform to continue to grow and develop ARMA and provide even better support to our members.

The Board We were humbled by the many nominations we had to serve on the ARMA Board, evidence of a strong commitment to our industry from our members.

CEO’S Report 2023 – Michelle Rose Each year, as I sit down to craft this portion of the Annual Report, it provides me with an opportunity to reflect on our accomplishments and share some of the most noteworthy highlights with our membership. This typically begins by revisiting what I wrote the prior year, which allows me to assess the strides we have made in the preceding 12 months. Looking back to almost three years ago, when I assumed this role amidst a rather tumultuous period, I collaborated closely with the Board to bring ARMA back to its foundational principles. The objective was to streamline our operations and eliminate the excess and unnecessary, to ensure our resilience during those challenging times. In doing this we were paving the way for ARMA to establish a stronger, stable footing for future growth. In alignment with this, I take great pride in our commendable membership retention rate and the profound sense of community 66 ROTOWORLD® ISSUE 4 • 2023

and support that ARMA has fostered within our industry. Thanks to your unwavering dedication and the meticulous management of ARMA, we find ourselves in an enviable financial position that promises security well into the future. This advantageous position also affords us the freedom to explore new projects with a fresh perspective. Our team has experienced significant expansion, which has been a fortunate development. Petro Geldenhuys now oversees our New Zealand members, while Zoe Perrington manages our overall membership and administrative matters. This augmentation of our resources has afforded me the time to cultivate new relationships with other like-minded organisations. I have also stepped onto the PLO-46 Committee for the ASNZS4766 amendment process – a responsibility that I initially believed was beyond my technical knowledge. I embraced the opportunity to learn what was

ARMO

NEWS necessary, with help from industry experts when needed. Thank you to those who continually provide me with their time and knowledge. Our collaboration with KBI Insurance has resulted in a successful partnership that resonates positively with our membership. I’ve also had the privilege of visiting members and supporters at their manufacturing facilities, something that we will continue moving forward. An exceptional highlight was Rotomould23, which offered a superb blend of networking and educational aspects set against the breathtaking backdrop of Queenstown. We were indeed fortunate to have Dru Laws join us once again, all the way from the USA.

During our strategic planning session last December, the Board set forth a renewed vision and purpose for ARMA. This was complemented by the inclusion of four principal pillars that guide our endeavours, ensuring the continued success of rotational moulding as an adaptable and sustainable industry: • Member Value & Engagement • Advocacy & Representation • Knowledge, Education & Training • Environment, Technology & Innovation Looking ahead, there are numerous projects scheduled for the upcoming 12 months and I look forward to implementing these with our Board, staff, and volunteers for the benefit of our members and supporters.

ARMA 2023 & Beyond In setting our new vision for ARMA through our current Strategic Plan, we work to ensure that rotational moulding continues to thrive as a versatile and sustainable industry. At the core of our mission, we strive to create a thriving and collaborative community that serves as a hub for innovation, education, and progress. By facilitating meaningful collaborations and knowledge-sharing opportunities, we empower our members to stay ahead of industry trends and excel in their respective fields. In line with our vision for a dynamic and digitally driven future, we have undertaken ambitious projects that are set to transform the way we serve our members. A comprehensive digital transformation is underway, designed to streamline and enhance member services, providing a seamless and efficient experience. Recognising the importance of education in empowering the next generation of rotomoulding professionals, we are working to introduce an online induction education program.

NEWS BRITISH PLASTICS FEDERATION ROTATIONAL MOULDING GROUP • BPF

BPF event to explore stimulating growth in recycling On 7 November the British Plastics Federation (BPF) hosted its annual plastics recycling seminar at the offices of Trowers and Hamlin, in the heart of London. Sponsored by The Environment Exchange, the event brought together companies from across the plastics supply chain to network and exchange ideas. The event opened with an introduction by the BPF Recycling Group Chairperson Roger Baynham, who is also the Managing Director of Philip Tyler Polymers. He was followed by AMI Senior Research Analyst Olivia Poole, who spoke on the UK and European recycling industries, providing insights into trends in the market and future expectations. A representative from Defra provided an update on the DRS/EPR infrastructure report, before the organisation’s Head of International Waste Shipments, Hazardous Waste, and Mercury Policy Robert Taylor discussed Defra’s consultation on delivering a ban of exports of plastic waste to non-OECD countries, as well as other regulatory reform. Justin Guest, partner at Archipelago Eco Investors, presented on ‘Investability in the Plastics Recycling Industry’, exploring EU

Regulation, technology risk, and future financing prospects. Alliance to End Plastics Waste Chief Adviser Doug Chamberlin presented on ‘How Collaboration Works Along the Value Chain’, covering how the Alliance convenes companies from across the value chain to try to effect systemic change. He discussed the ambition to have legally binding guidance and the role the UK industry can play. Following this there was a panel discussion called: ‘How Can We Stimulate More Growth in the UK Recycling Sector’ featuring Amie Stringer, Procurement and Trading Director at Viridor; RECOUP’s Policy and Infrastructure Manager and Tom McBeth and BPF Sustainability Manager Helen Jordan. This was followed by a talk from Carla Brian, Head of Partnerships (Major Projects) at Biffa, who provided insights into its innovative ‘Bottle to Bottle’ project. BPF Sustainability Manager Helen Jordan stated: “The recycling sector in the UK faces a number of challenges as it seeks to adapt to a changing landscape and evolving market conditions. We put together this event to provide a thorough overview of plastic recycling at this point in time.”

Do you know the True Cost of your ‘Time-to-Hire’? Navigating Turbulence to Recruit Future Talent It is no secret that recruitment is and always has been challenging. Since the Covid pandemic and the ‘Great Reshuffle’ that followed, recruiting, and retaining people at any level has become even more difficult. In a survey conducted by LinkedIn in 2022, 87% of recruiting professionals believe that the role of Talent Acquisition has become more strategic over the last year. Simply advertising a role in the traditional channels, is no longer enough and by doing so, talent professionals risk a ‘time-to-hire’ that, not only exceeds their industry average but also stretches both internal budgets and resource past their limits. To recruit the right person for their business, companies, and talent acquisition professionals in particular, must respond to the ever-changing business landscape. Navigating turbulence, change, and competition for highly skilled candidates will all be necessary to feed their talent pipeline. The True Cost of ‘Time-to-Hire’ Recruiting from outside an organisation into a leadership role is often the most challenging task of all. Leaders with excellent people engagement skills, high integrity, values aligned with the company and the ability to manage complexity and uncertainty, are highly sought, meaning competition is fierce. Companies presented with a resignation from a senior leader (whether expected or not) often face the daunting task of finding a suitable replacement, 68 ROTOWORLD® ISSUE 4 • 2023

whilst covering all the associated tasks and responsibilities of the role. All of this, on top of the need for the time and resource for the recruitment process, comes at a cost. Does the vacancy leave an open sales territory, or stretch those covering their own areas thinner? Will there be an impact on efficiency and process within the department? How long can you afford to pause continuous improvement projects, in lieu of an appropriate hire? On top of the tangible pressures already mentioned, it is also worth considering the time it will take for the new hire to get ‘up-to-speed’ and to become optimised in their new position. Futureproofing through your Talent Pipeline A combination of market factors affecting the industry broadly and the additional stressors of specific hiring requirements, all bring the whole area of talent acquisition to the fore. The pressure on ‘time-to-hire’ and the need for ‘smart’ recruitment processes mean that those best equipped to operate an effective talent-pipeline and succession planning strategy, will be most successful in, not only bringing the required talent into their business but also in retaining existing talent. Staying One Step Ahead Many larger organisations or groups have responded to the need for change by hiring their own internal talent leaders and departments, able to cope with the high-volume demands of such

ARMO

NEWS companies. By advertising via their own networks and using tools such as LinkedIn, this approach works well, particularly when combined with a strong employer brand and clear development plans. Sometimes, if a role is challenging or considered ‘hardto-fill’, they may reach out to a specialist recruitment partner to support their own search or to broaden their networks; it is important that any third-party is carefully selected to collaborate seamlessly with their own team. For smaller businesses with fewer resources, there are benefits to not only outsourcing individual recruitment projects but also in developing longer-term talent strategies with a specialist partner, enabling the recruitment consultants to act as an expert extension of the hiring company. The Impact ‘Time-to-hire’ on the Candidate Experience It is possible to reduce the ‘time-to-hire’ by working with a recruitment partner that has the market understanding, industry presence, network, and competencies to fulfil the need. By working on a long-term partnership with companies, to build knowledge and value into the relationship, it is easier to agree a clear briefing, work together for an exceptional candidate experience and to communicate in a way that proactively meets their expectations. The converse effect of not managing a process or partnership in this way, can lead to delays which, in turn, easily results in the loss of candidates to other employers or even a sense of apathy from the candidate, as momentum fades. Of course, this is not a new way of thinking, but it is important to recognise that the hiring process is two-way and that just as candidates must work hard and research well to impress

during assessment, employers and recruiters must present themselves in the best possible way to sell the opportunity to potential employees. Taking the time to ensure the process is not too onerous and providing constructive interview feedback to all candidates, will go a long way to create a lasting positive impression. How can you improve? Companies that have well-thought-out talent acquisition strategies, collaborative relationships with their recruitment partners, streamlined processes, and that work hard on the delivering a positive candidate experience will thrive in this demanding employment market. Those that stick to the more traditional approach, that is too employer-led, may struggle to bring in the talent that makes the difference. Listgrove’s Role Listgrove has evolved to become the leading industry expert and longest serving specialist recruitment provider to the global plastics, packaging, chemicals, petrochemicals, energy, and recycling sectors – but one thing remains the same: we champion performance through people. If you are looking for a recruitment partner that: knows your industry; will present your employer-brand with the utmost professionalism to attract the right talent; and reduce your ‘timeto-hire’, our specialist consultants are here to help.
