  • North American plastics sector holds steady, while riding a roller-coaster of uncertainty

    K 2022 – Trend Report North America Copyright: FabrikaPhoto 08.07.2022 The pandemic. Supply chain ruptures. The Great Resignation. China trade tensions. Climate change and extreme weather events. Soaring inflation. Stock market volatility. The war in Ukraine. Seldom in our lifetimes have we experienced such an extended period of disruption and uncertainty. North America's plastics industry has not been spared from these issues, but it has held up reasonably well, given the crucial role that plastic products play in our everyday lives, and especially in vital healthcare applications. If anything, the pandemic only helped to reinforce the value of plastics in helping to keep us all safe and healthy. "During the 2020 COVID-19 recession, stimulated by federal relief dollars, U.S. plastics consumption held up at a time when employment was down and capacity was constrained," noted the Washington, D.C.-based Plastics Industry Association (aka PLASTICS) in its "2021 Global Trends" report. The result was higher imports and a trade deficit." Plastics industry size & impact The association's "2021 Size & Impact Report," published last year, estimated the total value of U.S. plastics industry shipments in 2020 to be $394.7 billion. The industry directly employed 945,300 workers, which was down almost 6 percent from pre-pandemic 2019. Despite all the challenges, U.S. plastic products manufacturing rose 4.9 percent in 2021 from the prior year, according to U.S. Federal Reserve data, in line with the association's late-year projection. That number could have been higher, but resin production continued to lag, said Perc Pineda, noting that materials shortages weighed down plastic products output. Pineda, the group's chief economist, cited Federal Reserve data showing 2021 plastic materials and resin production down by 0.4 percent. Perc Pineda, Ph.D., Chief Economist, Plastics Industry Association Plastics machinery production last year rose by a robust 16.8 percent compared with the pandemic-ravaged 2020, and plastics mold manufacturing grew by a solid 9.7 percent in 2021. "While the outlook for 2022 remains positive, unresolved challenges in 2021 spilling over into 2022 will cause plastics industry growth to slow," PLASTICS projected in its latest quarterly outlook, published in December. Even so, the latest federal data for March 2022 indicate that U.S. plastics product manufacturing and resin production were up 7.6 percent and 14.1 percent, respectively, from March last year, according to Pineda. The U.S. plastics machinery market continues to see healthy demand while continuing to experience supply-chain bottlenecks, as well as high metal costs, due in part to Russian sanctions. Business investment spending on industrial machinery in the U.S. increased by 19 percent in the first quarter of 2022, compared with the same year-ago period, according to Pineda. However, low parts inventories are extending production times and slowing deliveries. Tooling sector rebounds Harbour Results Inc. (HRI), meanwhile, reported in April that the U.S. tooling industry rebounded in 2021, with companies seeing year-over-year revenue growth. HRI, a Southfield, Mich.-based manufacturing industry consulting and benchmarking company, published the insights in its "Q1 2022 Harbour IQ Manufacturing Pulse Study." Although 2022's first quarter started out slowly, HRI reports that shops are predicting utilization will reach 90 percent for molds and 82 percent for dies by this year's fourth quarter. "Despite all the chaos in the manufacturing marketplace, we are feeling positive about the opportunities for the tool and die industry in 2022," stated HRI President and CEO Laurie Harbour, noting projections for a sharp increase in automotive tooling orders this year. Packaging trends Copyright: nualaimages The pandemic spurred a notable boost in home shopping and e-commerce, to include food and grocery delivery services. This helped to accelerate interest in safe, durable, clear, lightweight and thin-wall plastic packaging options. Sustainability continues to command the attention of brands and packaging companies. But the Packaging Machinery Manufacturers Institute (PMMI) in May warned that innovation in the sector is not keeping pace with sustainability demands. Companies are under massive pressure to reduce packaging waste, but the PMMI study says that packaging operators recognize they are behind the curve in this regard and need to catch up. Building boom continues The construction sector is an entirely different beast and faces different challenges. Supply-chain disruptions have played havoc with builders. For the past couple years, the U.S. housing demand has been red-hot, and prices sky-high, with homebuilders struggling to keep pace. "Despite all of the turbulence reflected in some other sectors, total U.S. construction spending increased by a robust 12 percent in the first quarter when compared with the same period in 2021," according to Plastics News . "Total spending for residential projects jumped almost 19 percent, while spending in the nonresidential segment increased a very respectable 6 percent." Higher interest rates are likely to start cooling this sector somewhat. Consumer technology in demand Copyright: YouraPechkin The Consumer Technology Association (CTA), which organizes the huge CES consumer electronics show in Las Vegas each year, projected in January that U.S. consumer technology revenue would increase by 2.8 percent in 2022. It predicted that the industry's retail sales revenue this year would exceed $505 billion, marking the first time ever it will top the half-trillion-dollar mark. This increase is over and above the 2021's year-on-year growth of 9.6 percent. CTA reported that some of the fastest-growing products include many "smart" products – from smart appliances to smart TVs, as well as connected products such as sports and fitness equipment. Digital health devices also continue to grow in popularity, to include connected devices that monitor mental and physical health and manage chronic disease, as well as telemedicine and all types of wearables. Automotive industry woes The U.S. vehicle industry has taken a beating, for all the above-noted reasons, compounded by a critical shortage of the semiconductor chips needed in every vehicle. Analysts predict semiconductor inventories may not return to pre-pandemic levels until at least 2023. The National Automobile Dealers Association said new light-vehicle sales in the United States increased to 14.3 million units on a seasonally adjusted annual rate (SAAR) in April 2022, but it's still a far cry from the April 2021's annual rate of 18.6 million units. A people problem Technology, inflation and supply-chain challenges aside, the U.S. plastics industry (and broader manufacturing sector) has a potentially more intractable problem – a shortage of skilled workers to keep its plants humming. The pandemic caused many to re-evaluate their lives and careers, leading some to quit their jobs and others to pursue different paths. In addition to the U.S. having an aging population, it has proven difficult to attract, train and retain talent. Many of the new entrants to the labor market lack skills for, and/or are averse to pursuing a career in manufacturing, notes Pineda. "In a tight labor market, even economic incentives such as higher wages and benefits are not guarantees of attracting and retaining skilled workers. Increasing skilled labor supply would require serious commitment from the industry to implement an apprenticeship program that's consistent throughout the country and accredited by the U.S. Bureau of Labor," he said.

  • Covestro collaboration with SABIC unlocks improved recyclability for mono-material flexible plastic pouches

    Copyright: duskbabe 21.11.2022 Covestro has developed a proof-of-concept heat-resistant coating for use on mono-PE stand-up pouches made with SABIC ® BOPE polymer. The coating facilitates the industrial-scale production of BOPE-based mono-material stand-up pouches on horizontal form-fill-seal (HFFS) lines. This innovation paves the way for simple single-stream recyclability of flexible plastic pouches, marking an important step on the way to achieving a circular economy for packaging. Covestro and SABIC will continue their collaboration to further improve and eventually commercialize this product and bring its benefits to brand owners and consumers. A revolution in packaging materials Covestro has developed a heat-resistant coating for monomaterial stand-up pouches that enables easier single-stream recycling of these packages. The coating was developed for stand-up pouches made of biaxially oriented polyethylene (SABIC® BOPE). Source: Sabic Traditional flexible plastic packaging uses multi-material laminates, which are difficult to recycle as it is expensive and time-consuming to separate the different polymer layers. Driven by concern around packaging waste from consumers, governments, and industry, packaged goods brands are looking for more circular solutions. One increasingly popular option is mono-material packaging, made with materials such as BOPE. BOPE can be used to make flexible packaging in which all the layers are manufactured from PE polymer grades. This packaging can then be recycled in a single stream. However, BOPE-based mono-material stand-up pouches are difficult to manufacture at scale on FFS lines due to their low heat resistance compared with current PET- or PA-containing laminates. To solve this problem, Covestro engineered a heat-resistant coating for mono-PE BOPE-based stand-up pouches. This increases the pouches’ heat resistance so they can be manufactured on high-speed FFS production lines while maintaining high visual and performance qualities. Thanks to Covestro’s new coating, SABIC’s BOPE polymer can be a viable alternative to replace PA and PET containing multi-material laminates for flexible plastic packaging. "We take our responsibility to create lower-impact packaging seriously. Our circular economy strategy focuses on recyclable solutions that unlock pathways toward closing the loop on materials," explains Davide Reverdito Bove, Sector Marketing Manager at Covestro. "In SABIC, we found an expert partner. This close collaboration will enable us to accelerate the engineering and testing process of our new heat-resistant coating for BOPE with clear benefits for the product quality, the customer, and the planet." Exhibitors & products around plastics processing Processing technologies Follow on treatment of plastics products Supplying Product groups Products To all exhibitors in this category Catalyzing circularity in the packaging industry Covestro’s heat-resistant coating has several benefits for packaging manufacturers. It prevents heat seal bars from sticking during the sealing stage of the HFFS and VFFS process – allowing for a broader sealing temperature window and eliminating wrinkling and shrinkage. This enables the creation of high-performing mono-material flexible stand-up pouches with simple, single-stream recyclability. "Thanks to this heat-resistant coating solution for flexible packaging, manufacturers can meet challenges in processing, without compromising on the properties and machinability of the packaging," says Roel Beckers, Sales Manager at Covestro. "It allows a faster switch to mono-PE solutions and the use of the BOPE material as we work with global value chain partners who share our mindset of contributing to a more circular plastics economy." Covestro innovative heat-resistant coating enables brands, retailers, film producers, and others in the value chain to create new high-performance yet recyclable mono-material packaging – supporting the drive to achieve a circular economy for flexible packaging in Europe and beyond. Although the coating is currently at the proof-of-concept stage, Covestro and SABIC are excited to further develop this innovative solution into a commercial product, helping brands and consumers achieve their sustainability ambitions. By embracing open innovation, both Covestro and SABIC are also committed to working together with the full packaging value chain to accelerate the introduction of more circular packaging solutions to the market.

  • Researchers find a new method for recycling polystyrene

    This method would create an incentive for polystyrene to be collected and recycled instead of going into landfills Source: cavanimages 11.10.2022 Ocean trash and overflowing landfills have drawn widespread attention to the plastic waste that we put into our environment. In response, communities around the world work hard to reduce, reuse, and recycle. But what does it mean for something to be recyclable? A research team led by Guoliang "Greg" Liu, associate professor of chemistry in the College of Science, is working to expand the frontiers of plastic recycling. Many of us are comfortable tossing a metal can or a glass jar into the recycling bin without a second thought. But plastics are a bit different. Not every recycling plant is equipped to handle every type of plastic. That's because the chemistry and structure of plastic materials are diverse, and each type requires a specific recycling procedure. In a perfect world, perhaps there would be recycling plants all over the world equipped to handle every kind of plastic imaginable. But we're not there yet, due in part to the fact that some plastics are very difficult to recycle, and we have yet to develop effective, practical techniques for processing them. Polystyrene is one such challenging material. Best known as a major component in Styrofoam, polystyrene is widely used but rarely recycled. Many municipal recycling facilities instruct residents (including those in Blacksburg) not to put polystyrene in their home recycling bins. Polystyrene is one such challenging material.

Exhibitors & products around recycling Recycling plants Separating and sorting systems for waste Size reduction equipment (crushers, shredders, grinders) Compounding lines Recyclates Researchers sort through various objects made from polystyrene, a type of plastic that is rarely recycled. Source: Reilly Henson for Virginia Tech Currently, the main method for recycling polystyrene yields a product that is often too low-quality to make the process economically viable. In other words, if a recycling plant tries to recycle polystyrene on a large scale, it will either need a financial boost, such as a government subsidy, or the operation risks running out of money and shutting down. One solution to this problem is to improve the recycling process so that it becomes economically viable, or even better, economically attractive. With his experience in polymer chemistry and as an affiliate of the Macromolecules Innovation Institute, this is exactly what Liu was able to guide his team to do. In a paper recently published in the Proceedings of the National Academy of Sciences, the team presents a new method for recycling – or perhaps more accurately, "upcycling"– polystyrene. By exposing the material to ultraviolet light and adding a chemical catalyst, this method creates a product called diphenylmethane (DPM) that is immensely useful. DPM is used as a precursor in drug development, polymer manufacturing, and even as a fragrance in consumer products. Importantly, DPM has a market price that is 10 times higher than other materials that can currently be made from recycled polystyrene. The researchers took their investigation one step further: They wanted to confirm that this new method would achieve the economic viability they were striving for. The chemists from Virginia Tech teamed up with business experts from Santa Clara University and the Dongbei University of Finance and Economics, who ran an analysis to determine how profitable the recycling method would be overall. Their results showed that because DPM has such a high economic value, the costs of collecting and processing the polystyrene would be fully justified. This new recycling method would create an incentive for polystyrene to be collected and recycled instead of going into landfills or becoming plastic pollution. "I think it's important for people to realize that big global challenges like plastic waste can have — and most likely demand — multiple solutions," said Liu. "We at Virginia Tech can contribute a small piece to the big puzzle and offer solutions to positively impact the world."

  • A guide to sustainable plastics

    Exclusively for K-MAG Copyright: Gianni Diliberto 27.07.2022 As a designer, plastics and sustainability can be difficult to navigate. There are so many parameters to consider – from the origin and environmental footprint of raw materials to the durability and quality of specific materials and maximising the chances of recovery and recycling at the end of life of plastics products. Starting with the origin of the raw materials that go into plastics production, the vast majority of plastics today are petrochemical-based virgin materials, but increasingly plastic suppliers are exploring alternative raw materials such as bio-based feedstocks or recycled materials. Typically, suppliers offer plastics that are made with a combination of petrochemical- and bio-based raw materials, or virgin and recycled material. Always ask suppliers to confirm the ratio of specific raw materials and relevant certificates such as ISCC Plus or SCS Recycled Content. Chris Lefteri. The development of renewable, bio-based chemistry for plastics production is already well underway, with many plastic suppliers offering materials that are derived from a wide variety of plants – from agricultural food crops to by-products from forestry and plants that are more associated with the textiles industry. A small but growing number of plastic suppliers have also launched products that are based on carbon capture and utilization, CCU. Both topics are explored in the "Industry Climate Neutrality: Wish – Reality – Future" K Talk roundtable discussion, available to watch here . The specific type of plastic material will have a massive impact on the durability, functionality and user experience of plastic products. Generally speaking, commodity plastics such as polypropylene, polyethylene and PET will have a lower environmental impact than high-performance engineering polymers like ABS, polycarbonate and polyamide. Understanding the expected life-span and likely usage scenarios of a product is crucial for selecting the right material – the larger environmental footprint of an engineering polymer will be balanced if it is put to good use in a product with a long-life span. The use of additives to enhance certain properties and aesthetics of plastics are another element to consider in this context. Several suppliers and compounders offer non-halogenated fire retardants, antimicrobial additives that do not contain heavy metals, and non-toxic mineral-based colourants, to name just a few examples. Additives also have an impact on the recyclability of plastics, so it is always worth confirming the impact of specific additives with a recycler that is specialising in the type of plastic you are considering using. Designing for circularity with plastics is a big topic in itself that you can read more about in the Functional Plastics feature, but selecting the right type of recycled plastic is also a complex task that deserves a closer look. The vast majority of recycled plastics offered by suppliers will be available in black or shades of dark grey colour only. This is a result of the specific way that most plastics are recycled today, so-called mechanical recycling. This process takes plastic waste, separates it by type, grinds it down and remelt it into flakes or pellets that can be moulded into new plastic products. Most recyclers do not separate plastic waste by colour, meaning the resulting material will be an unattractive greyish-brownish mix of all the colours of the plastic waste. Most recyclers get around this problem by adding black or dark grey pigments to the recycled material to give it colour consistency. While black and dark greys are fine for many applications, there are several recyclers that specialise in colour separation for bright and light colour recycled plastics, as well as recyclers that are able to provide transparent recycled plastics. These materials require careful sorting and cleaning for good results, which means that they typically have a larger environmental footprint compared with black and dark grey recycled plastics that are less complex to recycle. In this context, selecting the right recycled plastic for the right application is crucial. This and other aspects of circular plastics are discussed in the "Climate protection and plastics - do they go together?" K Talk, available to watch here . Also be sure to take a look at the theme days programme at the Plastics Shape the Future space at K 2022, which covers many of the topics outlined above. Chris Lefteri More around Climate Protection

  • BASF's IrgaCycle™ stabilizes recycled plastics used to protect pineapples from sunburn in Malaysia

    Copyright: ADDICTIVE_STOCK 20.08.2022 ASF and 3T Industries Sdn Bhd, a leading recycling company in Malaysia dealing with post-industrial and post-consumer recyclates, are helping pineapple plantations in Malaysia to increase their yields and save resources. For the first time, 3T Industries has applied BASF's IrgaCycle TM UV033 DD to enhance 100% recycled high density polyethylene (HDPE) sheets used as protectors for pineapples. While pineapples require a warm and humid climate, they are susceptible to damage from solar radiation and high temperatures (> 32°C) which can significantly reduce marketable yield and cut deep into a grower's profit. Symptoms include sunburn or bleaching which are visible as yellow-white skin that turns pale grey or brown upon damage to the tissue underneath. This damaged tissue is susceptible to disease and infestation. The HDPE protector shields the fruit from direct sunlight while still allowing photosynthesis to occur. BASF's IrgaCycleTM helps pineapple plantations in Malaysia by stabilizing recycled plastics used in protecting pineapples from sunburn. Copyright: BASF "Plastic additives specifically for the agricultural sector are highly customized to fulfil critical customer needs for enhanced crop protection solutions," says Hermann Althoff, Senior Vice President, Performance Chemicals Asia Pacific. "We offer full customer support in all questions of quality improvement of recyclates to make them viable materials in new applications." Previously, 3T Industries used a combination of antioxidants and light stabilizers to achieve the performance requirements stipulated by the grower – the HDPE protectors needed to last through the intended service lifetime of four seasons. IrgaCycle offers a one-pack solution that is immediately available for the recycler without the need for further premixing. It is also more efficient at lower concentrations compared to traditional antioxidant systems and reduces the overall quantity of additives required. This results in easy and accurate dosing, improved product quality, as well as upgraded recyclate for use in long-term applications. "We use our expertise in recycling technology and post-consumer resins to provide better solutions to consumers and communities," says PH Tan, Managing Director of 3T Industries. "With IrgaCycle, we were able to use recycled feedstock to design a new product that features a high amount of recyclate content and makes more sustainable agricultural plastics possible." BASF not only provided 3T Industries with the suitable additive solution, but also the technical recommendations to stabilize the recycled polymers during processing and outdoor weathering. This is important as an effective and sustainable application of recycled materials depends on, amongst others, the optimization of process conditions and modifying agents. Launched in 2021, IrgaCycle consists of a series of plastic additive formulations, which enable recycled plastics to be reused for the production of high-value plastics in combination with virgin materials. The additive solution addresses specific quality issues associated with recycled resins, such as limited processability, poor long-term thermal stability and insufficient protection from outdoor weathering. The IrgaCycle range is offered as part of the VALERAS ™ portfolio. In addition to enabling plastics circularity with IrgaCycle, VALERAS solutions bring significant sustainability value to plastic applications by improving durability, saving energy, as well as reducing waste and emissions.

  • Researchers use light to convert abundant lignin into plastic that can be continually recycled

    New process could advance a waste-free system of polymer manufacture and re-use Copyright: mstandret 05.04.2023 Lignin is arguably the most abundant component of biomass that most people have never heard of. That may be about to change. Many people are familiar with its biochemical cousin cellulose, a byproduct of paper and wood milling. But the same processes produce 50 million tons of lignin annually, industry experts estimate. Once distilled, 98 percent of the inky liquid is burned to produce electricity. Scientists have been working to find more efficient and sustainable approaches to transform this naturally occurring polymer for use as a cleaner and greener building block to develop next generation materials. Boston College chemists have developed an approach that uses light to transform lignin into sustainable plastics, the team reported recently in the journal ACS Central Science . " We developed a catalyst that can selectively break down specific chemical bonds in lignin when it is exposed to light, such that the lignin is converted into intermediate-sized, soluble molecules called oligomers," said Boston College Assistant Professor of Chemistry Jia Niu, a co-author of the study. The team then converted the oligomers into sustainable plastics by reacting with a molecular glue called crosslinkers, according to the report. Because of the unique chemical structures of the oligomers created by the catalyst, the plastics made in this way can be chemically broken down back into the oligomers, and reformed from the oligomers and the crosslinker. The findings advance a potential strategy for the waste-free system of polymer manufacture and re-use known as the circular plastic economy, said report co-author Dunwei Wang, Boston College’s Margaret A. and Thomas A. Vanderslice Chair in Chemistry. "Transitioning from petroleum to biomass as the feedstock for energy and material production can help to address some of the most important challenges our society is facing, such as climate change and plastic pollution," said Wang. "New methods that can make advanced materials from lignin will greatly improve the efficiency for biomass utilization." Wang and Niu, who share an interest in making sustainable materials, arrived at the project based on Wang’s expertise using photocatalysis to drive chemical transformations and Niu's work making recyclable polymers. "The pleasant surprise was the level of controls we were able to exert in decomposing lignin, which is a biopolymer that is notorious for its difficulty to break down," said Wang. "Such a level of control paves the way for downstream applications." The research team aims to further develop the novel method that converts lignin into sustainable plastics that can be readily recycled through chemical means.

  • New PET-like plastic made directly from waste biomass

    Source: orcearo 11.07.2022 "We essentially just 'cook' wood or other non-edible plant material, such as agricultural wastes, in inexpensive chemicals to produce the plastic precursor in one step" A 3D-printed “leaf” made with the new bioplastic. Source: Alain Herzog (EPFL) It is becoming increasingly obvious that moving away from fossil fuels and avoiding the accumulation of plastics in the environment are key to addressing the challenge of climate change. In that vein, there are considerable efforts to develop degradable or recyclable polymers made from non-edible plant material referred to as "lignocellulosic biomass". Of course, producing competitive biomass-based plastics is not straightforward. There is a reason that conventional plastics are so widespread, as they combine low cost, heat stability, mechanical strength, processability, and compatibility – features that any alternative plastic replacements must match or surpass. And so far, the task has been challenging. Until now, that is. Scientists led by Professor Jeremy Luterbacher at EPFL's School of Basic Sciences have successfully developed a biomass-derived plastic, similar to PET, that meets the criteria for replacing several current plastics while also being more environmentally friendly. "We essentially just 'cook' wood or other non-edible plant material, such as agricultural wastes, in inexpensive chemicals to produce the plastic precursor in one step," says Luterbacher. "By keeping the sugar structure intact within the molecular structure of the plastic, the chemistry is much simpler than current alternatives." The technique is based on a discovery that Luterbacher and his colleagues published in 2016, where adding an aldehyde could stabilize certain fractions of plant material and avoid their destruction during extraction. By repurposing this chemistry, the researchers were able to rebuild a new useful bio-based chemical as a plastic precursor. "By using a different aldehyde – glyoxylic acid instead of formaldehyde – we could simply clip 'sticky' groups onto both sides of the sugar molecules, which then allows them to act as plastic building blocks," says Lorenz Manker, the study's first author. "By using this simple technique, we are able to convert up to 25% of the weight of agricultural waste, or 95% of purified sugar, into plastic." The well-rounded properties of these plastics could allow them to be used in applications ranging from packaging and textiles to medicine and electronics. The researchers have already made packaging films, fibers that could be spun into clothing or other textiles, and filaments for 3D-printing. "The plastic has very exciting properties, notably for applications like food packaging,” says Luterbacher. “And what makes the plastic unique is the presence of the intact sugar structure. This makes it incredibly easy to make because you don’t have to modify what nature gives you, and simple to degrade because it can go back to a molecule that is already abundant in nature."

    Enhancing Circularity in Aerospace Manufacturing: The National Composites Centre's New Initiative

    Pioneering advancements in composite recycling to significantly reduce waste in aerospace production Copyright: National Composites Centre 07.06.2024 The National Composites Centre (NCC), in collaboration with Munich-based Cevotec, showcases a sustainable solution for aerospace manufacturing waste, aiming to reclaim up to 80% of dry fibre material. This proof-of-concept could revolutionize waste management practices by utilizing innovative Fibre Patch Placement technology. Economic Significance and Background The aerospace sector, pivotal to the UK's economy, faces stringent demands for lighter, faster-produced aviation systems while adhering to net zero targets. Traditional waste disposal methods such as landfilling are increasingly untenable due to rising costs and environmental impacts. Copyright: National Composites Centre Addressing Recycling Challenges in Aerospace In aerospace manufacturing, significant material waste occurs during the ply cutting phase, where up to half of the virgin materials are discarded. The NCC's initiative focuses on recycling these materials to maintain their value and utility in the manufacturing chain. Exhibitors & products around recycling Recycling plants Separating and sorting systems for waste Size reduction equipment (crushers, shredders, grinders) Compounding lines Recyclates Introducing Technology for Innovative Recycling Cevotec's Fibre Patch Placement (FPP) technology plays a crucial role here. By cutting carbon dry fibre waste into specific patches, this technology ensures efficient use of materials. The NCC team employs automated ply cutters to create precise patches needed for effective FPP application. Florian Lenz, Technical Director for Cevotec, emphasizes the adaptability and efficiency of this method: "Fibre Patch Placement technology offers a new option for flexible and productive composite manufacturing, generating value from material scrap." Copyright: National Composites Centre Showcasing Results and Environmental Benefits Material Reclamation: Initial tests show a potential to reclaim nearly 40% more virgin materials, thus reducing waste significantly. Economic Impact: Utilizing waste as FPP feedstock could save approximately £912,000 annually from a single aerospace component by reducing landfill deposits. Expanding Impact and Planning for Future Developments Looking ahead, the use of FPP technology is expected to extend beyond single components, potentially incorporating more of the aircraft build and thus amplifying environmental and financial benefits. The integration of digital technologies could further optimize the manufacturing process and material usage. Tim Young, Head of Sustainability at the National Composites Centre, outlines the broader vision: "To achieve net zero, we need to invest in new ways to reduce and remove carbon emissions from how we consume it: from concept, design, and manufacture to end-of-life recycling and disposal." Copyright: National Composites Centre Exploring Future Developments in Sustainable Manufacturing The NCC plans to refine the FPP technology for more complex components and collaborate with industry partners to test these innovations in real-world settings. This will include a broader evaluation of sustainability and economic impacts associated with dry fibre manufacturing waste. Source National Composites Centre More around Recycling
