  • 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. 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. 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.

  • 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."

  • Reusing odor-contaminated plastics

    Source: twenty20photos 01.07.2022 Plastic recyclates, like materials from the recycling bin, often have unpleasant odors due to their composition or due to impurities. This means that they are currently unsuitable for many applications, especially indoors. Sandwich specimen with a core of recyclate (brown) and a skin material without odor barrier additives during sensory evaluations. Source: Fraunhofer IVV To prevent odor release from plastic recyclates, the odor-contaminated plastic can be "packaged". For example, sandwich injection molding can be used to produce components that consist of an odor-contaminated core material and a completely enveloping skin made of an odor-neutral material. To enable the circular plastics economy, the core material and skin consist of the same class of plastic. However, long-term tests at elevated temperatures show that odors can migrate through the enveloping skin within a few days, causing the components to release odor emissions again. To achieve a permanent odor barrier effect, the chemical compounds of the odor must be prevented from migrating through the enveloping skin. Sandwich specimen with odor barrier skin. Source: Fraunhofer ICT In the Fraunhofer Cluster of Excellence Circular Plastics Economy CCPE, the four Fraunhofer institutes Fraunhofer ICT, Fraunhofer LBF, Fraunhofer IVV and Fraunhofer IAP are jointly investigating odor barrier skins for polymer compounds made from recycled materials. Using special additives, which are already incorporated into the skin-forming plastic before the component is manufactured, odor barrier skins can be effectively achieved with a skin thicknesses of 0.25 mm. Using this technology, high-quality applications using odor-contaminated recyclates are achievable, making an important contribution to resource conservation. The technology can also be transferred to other odorous materials such as plastics containing natural fillers.

  • Sensor-based symphony: sorting and recycling in perfect harmony

    Interview with Fabrizio Radice, Head of Global Sales and Marketing, TOMRA Recycling Exclusively for K-MAG Source: TOMRA Recycling 30.07.2021 What can be recycled, and what can't? Sorting waste is a challenge – for both people and machines. TOMRA, pioneer in this field has introduced its new generation AUTOSORT in 2020 under the motto "Symphony of all sorts". This is intended to take the plastics industry a big step further towards sustainability. Fabrizio Radice. Source: TOMRA Recycling In an interview with K-MAG and EuroShop.mag, Fabrizio Radice talks about the new AUTOSORT, what recycling has to do with a symphony and what responsibility the retail industry has when it comes to sustainability. You introduced your new AUTOSORT last year. What's so special about it? Fabrizio Radice: AUTOSORT® is our core product for which we offer additional complementary products that can be used for various applications. It combines leading-edge features and technologies in one sorting machine: Equipped with sophisticated infrared sorting technology which combines near infrared (NIR) and visual spectrometers (VIS), AUTOSORT® can accurately and quickly identify and separate different materials according to their material type and color, extracting high-purity high-value end fractions. It is compact and ultra-flexible in design and thus allows for an uncomplicated integration into existing and new plants. Given its multifunctional nature the unit’s several different sensors can be combined to meet the bespoke needs of our customers. Apart from that, our customers particularly profit from AUTOSORT's outstanding technologies: FLYING BEAM®: The illumination unit is positioned inside the scanner and ensures a homogenous light distribution across the entire belt. This in turn means that more materials can be scanned, analyzed, and sorted. GAINTEXX (optional) is a deep learning-based sensor that classifies objects and sorts objects that have previously been hard to sort. Moreover, it proves to be highly adaptable to waste streams making it a future-proof solution for our customers. DEEP LAISER significantly increases the sorting accuracy of the machine. Thanks to its smart segmentation, it distinguishes between two overlapping objects enabling object-based recognition even at high throughputs. The upgradability of AUTOSORT® makes it a future-fit sorting solution for our customers. Exhibitors and products around machinery and equipment Machines and equipment for preprocessing and recycling Machinery and plant for processing Post processing machines and downstream equipment Process automation Digitalization Parts and components You came up with something special for the launch: A live launch event under the motto of a "Symphony of all sorts." Why did you decide on this? Radice: Previously, the product launches were originally due to take place at IFAT 2020, but with the event cancelled due to Covid-19, we adapted our plans and instead launched the new products on a digital platform broadcasted from Germany. At first glance, there might not seem to be an association to topics considered in recycling. On second glance, there is: the symphony reflects the recycling process, which can only be highly effective if all the instruments involved, including TOMRA's new complementary products, form a perfectly harmonized symphony to sort all types of waste with high accuracy and sophistication. What exactly was the event like? Radice: The event was a one-hour session broadcasted from a studio near the company's headquarters. Approximately 1000 participants (delegates world-wide, including representatives from a number of international and regional press titles) listened to various presentations explaining the “Symphony of all sorts” concept and introduced the new generation AUTOSORT® as well as its complementary products, AUTOSORT® SPEEDAIR and AUTOSORT® CYBOT . A closing, interactive Q&A session enabled delegates to find out more about the new products' capabilities and hear about TOMRA's predictions for the global future of sensor-based sorting. Source: TOMRA Recycling To what extent do you contribute to more sustainability with your sensor-based sorting machines? Radice: We are both a technology provider and consultant. We help partners, plant builders and customers to find the best suitable sorting solution for their respective needs and sorting requirements. Once established, we provide the respective sorting solution that is an integral part of a recycling and/or sorting plant in which it recovers valuable materials out of waste streams. To give an example: an AUTOSORT® sorting unit can recover different plastics types out of different waste streams, such as municipal solid waste, separate collections and many more. The more materials the machine recovers at high purity rates, the more material can be recycled to high qualities and made available on the market. Consequently, brand owners and converters have access to these recyclates and can use them in the production of their materials rather than primary resources. This in turn, promotes greater sustainability. Source: TOMRA Recycling What significance does the K – The World's No. 1 Trade Fair for Plastics and Rubber have for you? Radice: We have exhibited at K numerous times and consider it an important platform to present our plastics sorting solutions, to inform about the market and future trends, to use valuable networking opportunities. Moreover, it is a good event to highlight the need to shift to a circular economy – a transition that we strongly contribute to. In 2022, we will be present as exhibitor again and are looking forward to welcoming a lot of guests at our booth. Recycling and sustainability are also playing an increasingly important role in the retail sector. How do you think this aspiration can be implemented there? Radice: Consumer awareness has been strengthened considerably over the last time, making them push for more recycled and sustainably developed products. To offer more such products, they must be designed for recycling in a first place. Afterwards, proper collection and sorting must be granted before pure material fractions are sent to recycling facilities, transformed to virgin like recyclates and made available to brand owners and converters on the market again. Design for recycling is key. For instance, if a products' body is covered by a shrink sleeve made of another material and is hard to separate from the body (if not done manually by the consumer), recycling is hard to impossible. Would you like to learn how this problem can be solved and sustainability implemented in retail? Fabrizio Radice has told us more about this.

  • New method to convert plastic trash into clean hydrogen fuel

Scientists from Nanyang Technological University, Singapore have developed a new method for plastic waste to be converted into hydrogen based on pyrolysis, a high temperature chemical process. Copyright: NTU Singapore Unlike PET plastic bottles which can be recycled easily, plastic litter containing contaminated food packaging, styrofoam and plastic bags, is challenging to recycle. They are currently incinerated or buried in landfills, leading to both water and ground pollution. Using pyrolysis, plastic litter can then be converted into two main products, hydrogen and a form of solid carbon, called carbon nanotubes. Hydrogen is useful for generating electricity and powering fuel cells like those found in electric vehicles, with clean water as its only by-product. To further refine the new conversion method and to assess its commercial feasibility, the research team is test-bedding it on the NTU Smart Campus to treat local plastic waste, in partnership with Bluefield Renewable Energy, a local environmental firm that specialises in mobile waste to resources technologies. The multimillion-dollar research joint project, supported by the Industry Alignment Fund-Industry Collaboration Projects (IAF-ICP) administered by Singapore’s Agency for Science, Technology and Research (A*STAR), aims to develop feasible solutions to economically scale up the conversion of waste plastics to hydrogen over the next three years. The project will also explore the potential of other emerging technologies for decentralised waste management. The conversion of challenging waste streams into energy and valuable resources, such as syngas, biochar, activated carbon and carbon nanotubes will be investigated. With 832 million kilogrammes of unrecycled plastic waste generated in Singapore annually, the converted energy could potentially power up to 1,000 five-room apartments for a year. Led by Associate Professor Grzegorz Lisak from NTU’s Nanyang Environment and Water Research Institute (NEWRI), the research project used marine litter collected from local waters in collaboration with the Ocean Purpose Project, a non-governmental organisation and social enterprise based in Singapore. With 269 million kilogrammes of plastic waste currently floating in the oceans, the NTU team estimates that if converted into energy the waste could power an electric vehicle for 20 to 40 million kilometres – 500 to 1000 times the Earth’s circumference. "As part of NTU’s sustainability drive, in developing new ways to turn trash to treasure, we are looking to convert waste plastics that cannot be recycled into high-value chemicals and resources, such as hydrogen fuel, synthetic fuel that could replace petrol, and carbon nanotubes used for many industrial applications," explained co-inventor Assoc Prof Lisak, Director of the Residues, Resource and Reclamation Centre (R3C) at NEWRI, who is also a faculty at the School of Civil and Environmental Engineering. Last November, NEWRI researchers participated in Race For Oceans Singapore, a kayak race organised by the Ocean Purpose Project, to collect plastic waste along the shores of Singapore. The purpose was two-fold – to clean up marine litter through sports as community mobilisation and to use these litter as research materials for developing an efficient plastic waste-to-hydrogen process. Ms Mathilda D'silva, CEO and Founder, Ocean Purpose Project, said: "Our collaboration with NTU NEWRI comes at a critical time when we need to rethink how plastics are recycled in Asia. As evident in our recent collaboration for the Ending Plastic Pollution Innovation Challenge (EPICC) United Nations Development Programme, where NTU NEWRI showcased how plastics in Lombok, Indonesia could be converted into hydrogen, it is clear that there is an untapped and highly available resource of ocean plastic that can be converted into the fuel of the future: hydrogen, which will prove a gamechanger in removing ocean pollution at scale. The cutting-edge research, innovation and dynamism of the NTU NEWRI team is a dream collaboration for NGOs like us in ocean conservation, who have to move beyond awareness campaigns and beach clean ups towards completely disrupting our ideas of how plastic waste should be handled. We are proud as plastic-to-resources influencers to promote our Singapore-based research that will forge a new future for plastic recovery, potentially cleaning thousands of coastlines in Asia." Mr Craig Gavin, CTO, Bluefield Renewable Energy (BRE), said: "During this pandemic, there has been an increase in plastic usage as most of us have been taking away our food in plastic containers and doing more grocery shopping. Current practices and efforts to recycle them have been challenging and require disposals in landfills and/or incineration plants leading to environmental contamination issues. In BRE, we pride ourselves in our ability to convert wastes into resources based on our flexi-pyrolysis system. Collaborating with NTU NEWRI has allowed us to utilise these environmentally unfriendly plastic waste stream as a feedstock and converting them into valuable resources. With the market pivoting to a Hydrogen powered economy, this collaboration allows us to expand our technological applications and commercialised locally created innovations, ultimately building a Singapore centred resource hub." The research team says the solid carbon from their new conversion process is much easier to store as compared to gaseous CO 2 emissions from plastic waste incineration. Furthermore, the solid carbon can be easily sold as a manufacturing feedstock for speciality chemicals or biofuels. For instance, it is a greener source of carbon for making carbon nanotubes, which is useful for many applications such as for batteries and composite manufacturing, says NEWRI Senior Research Fellow Dr Andrei Veksha, the co-inventor of the process who is piloting the technology. Plastic waste-to-hydrogen is a two-stage process: plastic waste is first decomposed upon heating into gases that contain low concentrations of hydrogen molecules. During the second stage, when the gases enter a reactor filled with a catalyst, the technology enables the release of hydrogen fuel and the formation of carbon nanotubes. If the initiative is successful, it will help Singapore reduce the amount of total waste disposed and prolong the lifespan of Singapore’s only landfill, Semakau Landfill, which is estimated to run out of space by 2035.

  • Polypropylene recycling from carpet waste

    Source: PantherMedia / a_oldman 07.06.2021 A significant part of carpet waste consists of petroleum-based polypropylene. As a non-recyclable product, disposing of it has previously meant incineration or landfill. However, a new solvent is now making it possible to recover virgin-standard polypropylene from carpet waste — with no perceptible reduction in quality. Developed by the Fraunhofer Institute for Building Physics IBP and its partners, the process also involves costs that are quite competitive. The development has taken place as part of the ISOPREP EU project. The EU alone produces around 1.6 million tons of carpet waste every year. The majority of this ends up being sent to landfill or incinerated, as carpet is a composite material that is not suitable for purely mechanical recycling methods. With carpet waste analysed in the project consisting of around a quarter polypropylene, a petroleum-based plastic, the result is a great deal of resources going to waste. Exhibitors and products around preprocessing and recycling: Mixers Size reduction equipment (crushers, shredders, grinders) Extrusion lines for compounding Recycling plants Separating and sorting systems for waste Carpet recycling now possible thanks to a new process A team of researchers, including from Fraunhofer IBP, has now developed a new recycling process as part of an EU project named ISOPREP. "For the first time, this is making it possible to recover polypropylene from carpet waste — and the outcome is virgin-quality," says Maike Illner, a researcher at Fraunhofer IBP. Not only does this allow the recovered polypropylene to be used in lower-quality products (in a process known as downcycling), but it also means that the quality is similar to that of newly manufactured polypropylene, making the material suitable for high-quality products too. The process is based on a special solvent in the form of an ionic liquid. With the right components, it is able to selectively extract polypropylene from carpet fibers. Before the team of experts applies the solvent, the carpet waste is cleaned — something which involves removing as much of the backing as possible — and broken down. Once the pretreatment is complete, the waste is fed into a reactor in which it undergoes treatment using the solvent. The polypropylene is selectively dissolved in the solvent, a method that provides an effective way of removing dyes and other additives. The process is already being used on an extensive laboratory scale involving several liters of the solvent — and now, the research consortium has set its sights on scaling the process up to a pilot plant with the ability to recycle a ton of carpet waste per day. The pilot plant is set to commence operation by the end of the project in March 2022. Costs and environmental impact Ultra-pure polypropylene from the ISOPREP process; Source: ISOPREP A recycling process can only be deployed on a large scale if its costs are competitive. For this application, this means retaining as much of the expensive ionic liquid as possible in the cycle. "If loss rates can be kept to one percent or less, there is potential for the costs of the process to rival those of producing new polypropylene," explains Illner. "We know this thanks to a preliminary economic analysis that we conducted at Fraunhofer IBP." The analysis involved the Fraunhofer researchers investigating the quantities of material and energy that would be required for the process and what kind of product would be output, and then calculating the associated costs. The team also considered how the costs would develop over the long term. Fraunhofer IBP is focusing on the ecological aspects of carpet recycling. It is able to draw conclusions from factors including a lifecycle assessment, which sheds light on the emissions that are produced during the recycling process, for example. If the consortium is able to achieve its aim of keeping solvent loss rates to one percent or less in this case too, primary energy requirements and greenhouse gas emissions will remain on a similar scale to those involved in producing new polypropylene. Potential for transfer to other polypropylene waste streams While carpet waste is the focus of this particular project, the process that has been developed has potential applications far beyond it. The experts involved believe that it could be transferred to a whole host of waste flows that contain polypropylene and are unsuitable for conventional recycling methods. "One example is polypropylene products that contain dyes and additives," says Illner. "Until now, it has been difficult to extract them from plastic, which means that the recycled polypropylene has only been suitable for use in lower-quality products." The new process separates the polypropylene not only from other materials, but also from dyes and other additives, allowing it to be used in high-quality applications.
