From the Sector

Breaking new ground in plastics recycling means assessing the value chain from end to end. The big opportunities for the future are in fine-tuning the individual process steps; from the collection of recyclable materials to the recycling process and the end product. This is where the cooperation of Lindner and the EREMA Group comes in, officially launched following the 50/50 founding of the holding BLUEONE Solutions in August 2023 to which shares of Lindner Washtech were contributed. The expertise of EREMA, a manufacturer of extruders and filtration solutions for plastics recycling and the largest company within the EREMA Group, has now been combined with the expert know-how from Lindner Washtech, a leading provider of all-in-one solutions for shredding, sorting and washing plastic feed materials.

Data transfer ensures more efficient recycling processes
Process control is an especially important aspect of plastics recycling, which is why standardising the process control system was what the two companies focused on first. "Together, we have developed a platform that allows data to be exchanged between the extruder and the washing system," says Manfred Hackl, CEO of the EREMA Group at IFAT in Munich. "This enables us to analyse the data more precisely so that effective improvement measures can be deduced." All key parameters are taken into account and monitored via a digital interface. For example, it is possible to use information relating to the current throughput of the EREMA Pre Conditioning Unit to optimise the washing process as soon as possible so that it can compensate for fluctuations in capacity and achieve a significant increase in output. This data transfer represents a new step on the roadmap to digitalization.

High efficiency due to smart energy management
"To ensure sustainable recycling, it is necessary to find the right process for each application and to make sure that the individual process steps are perfectly coordinated," emphasizes Michael Lackner, Managing Director of Lindner. Coordinating the process steps has already achieved initial success in energy management, and a clear example of this is heat recovery. "We use the latent heat generated during the extrusion process as an energy source for the washing and drying process," explains Lackner. "This enables our customers to sustainably reduce their energy costs and carbon emissions".

Making the most of synergies along the value chain
Synergies need to be used to establish the quality standards specified for each end application. "The key question is how we can improve the end product and increase the overall efficiency of the recycling process at the same time," agree Manfred Hackl and Michael Lackner. This will only work if companies work together along the value chain. The industry leaders can already point to several examples where together they have improved recycling processes and made it possible to move away from downcycling. "An example of this is the recycling loop of HDPE starting material, which is processed into high-quality, food-safe rHDPE pellets using our two technologies," says Lackner. Lindner Washtech and EREMA continue to work intensively together to develop strategies for upcycling plastics and increase recycling rates.

Vision and technology are the key ingredients of a ground-breaking school blazer that is showing how businesses can move to a circular textiles economy.  
 
While many brands are grappling with the complexities of inevitable legislation and engrained business models, leading school uniform producer, David Luke, has launched a fully recyclable ‘circular’ school blazer that is designed to be recycled through Project Re:claim, the world’s first commercial-scale polyester recycling plant.
 
Project Re:claim is a joint venture between the UK’s largest charity textile collector, The Salvation Army, and leading circularity specialists Project Plan B. The plant opened in the UK in January 2024, and presents huge opportunities for brands to transition to textile-to-textile manufacturing models.
 
David Luke’s circular blazer has been introduced to the brand’s successful Eco-uniform range which has sold over 1.7 million Eco-blazers in the last decade. Up until 2023, David Luke’s Eco-blazer, like many recycled garments, has been made from recycled plastic bottles. But the company has been working with Tim Cross, CEO of Project Plan B and the Circular Textiles Foundation, to bring the 100% recyclable blazer to market.
 
Tim Cross said: “David Luke has grasped the opportunity to embed 100% recyclable and 100% recycled garments into their range, starting with the school blazer. We now have the technology to enable their blazers to be recycled without any separation of the garment, making it an efficient recycling process. The team at David Luke has worked tirelessly with their manufacturers to create a blazer that does not compromise on design or quality, and yet is much kinder to the environment.”
 
Every detail from the lining, buttons and zips to the inter-linings and adhesives, has been re-thought and re-designed to meet the demands of an everyday school blazer and to recycle the garment once it reaches its end-of-life. Up until now, when the blazers have eventually been handed down to siblings, or given to the local charity shop, there had been no end-of-life solution for polyester garments apart from incineration. Now, Project Re:claim can recycle the blazer to produce polyester pellets, which are then spun into yarn to be used for future David Luke circular blazers.
 
Cross continues: “David Luke has the vision to create a fully circular range, and we have the potential to supply recycled content. The possibilities are infinite in terms of the future of garment design and manufacturing.”
 
Kathryn Shuttleworth, Chief Executive of David Luke, said: “It is a natural next step for us to transition to a textile-to-textile model. We have been producing garments using recycled plastic bottles for 15 years, but we have always had an eye on developments in textile recycling and solutions for end-of-life garments.”
 
In 2020, David Luke was awarded the Queen’s award for Enterprise for Sustainable Development and in January 2023 the David Luke circular blazer achieved Circular Foundation Textile certification.
 
Shuttleworth added: “Our focus will always be on those essential ingredients for parents and children - style, durability and affordability. But we have a responsibility to change our business model to better protect children’s future and the environment. It has become our obsession to make uniforms that meet our customers’ demands. We are really excited about the future as we continue to develop our range.”
 
Majonne Frost, Head of Environment and Sustainability for Salvation Army Trading Company, said: “Our vision is to enable companies to produce uniforms, corporate wear, fashion garments and textile ranges using recycled polyester.  We have the infrastructure to collect donations at scale and we now need companies to step up. This is an opportunity for companies to make a commitment to significantly reduce their environmental impact, and David Luke are showing us how that is possible.”

CARBIOS and Hündgen Entsorgungs GmbH & Co. KG (Hündgen), a waste management expert in logistics, sorting services and the recycling of recyclable materials from waste mixtures, announce the signing of a non-binding Memorandum of Understanding relating to the sourcing, preparation and recycling of 15kt/year of post-consumer PET waste using CARBIOS’ biorecycling technology at its first commercial plant in Longlaville, from end 2026.

The partnership will leverage Hündgen’s expertise and network in the sourcing and preparation of light packaging waste collected from German households. This PET waste will be prepared into flakes ready for biorecycling using CARBIOS’ enzymatic depolymerization technology, which produces food-grade PTA and MEG, further re-polymerized into PET.

The supply partnership with Hündgen contributes to securing the majority of CARBIOS’ feedstock needs for its first commercial plant in Longlaville, France. This plant will have a 50kt/year capacity when it will be fully operational and is currently under construction. This latest sourcing announcement comes in addition to previously announced agreements, such as with Landbell Group for food trays from Germany, and the winning CITEO tender for trays in France. The location of the Longlaville plant is strategically close to nearby waste supplies in Belgium, Germany and Luxembourg.

Through its enzymatic depolymerization process, CARBIOS can process all types of PET waste, including waste that cannot be recycled with current technologies. Multilayered, colored, and opaque packaging waste as well as polyester textile waste now have circular recycling solutions.

CARBIOS celebrated the groundbreaking ceremony for its PET biorecycling plant in the presence of representatives of local authorities, partner brands and industrial partners who all make up CARBIOS’ ecosystem. Located in Longlaville, in the Grand-Est region of France, CARBIOS' first commercial plant will play a key role in the fight against plastic pollution, offering an industrial-scale solution for the enzymatic depolymerization of PET waste in order to accelerate a circular economy for plastic and textiles. The plant will have a processing capacity of 50kt/year of prepared waste when operating at full capacity. Work is progressing on schedule with significant quantities delivered to customers in 2026.

CARBIOS' technology enables PET circularity and provides an alternative raw material to fossil-based monomers, giving PET producers, waste management companies, public bodies and brands an effective solution to meet regulatory requirements and their own commitments to sustainable development. The plant will have the capacity to process 50,000 tons of prepared PET waste per year (equivalent to 2 billion colored bottles, 2.5 billion food trays or 300 million T-shirts). The plant will create 150 direct and indirect jobs in the region. In October 2023, CARBIOS obtained the building and operating permits for the site. The factory is currently under construction on land officially acquired from Indorama Ventures on 14 February 2024. In February 2024, CARBIOS and De Smet Engineers & Contractors (DSEC) announced their collaboration to manage construction. Several feedstock supply agreements, notably with CITEO and Landbell Group, will secure the vast majority of the raw materials required.  Close to the borders with Belgium, Germany and Luxembourg, the plant's location is strategic for access to nearby waste supplies

CARBIOS was awarded 1st prize in the "So French So Innovative" Award organized by Business France, the Hong Kong Committee of French Foreign Trade Advisors (CCEF), La French Tech and its partners at InnoEX 2024 (taking place in Hong Kong from 13 to 16 April). The award recognizes French innovation to promote and support French Tech in the Asia-Pacific region. The final awards ceremony was held on the French pavilion in the presence of members of the Hong Kong Government and Christile Drulhe, Consul General of France in Hong Kong.

Emmanuel Ladent, CEO of CARBIOS: "Asia-Pacific is a key market for our PET biorecycling solution, and the 'So French So Innovative' Award is a recognition that supports CARBIOS’ prospection and commercial deployment in the region. CARBIOS' technology is generating a lot of interest, leading to promising discussions and the exploration of commercial agreements to support the sustainability commitments and international operations of current and future partners."

CARBIOS' global presence
In a dynamic global PET market, where the share of recycled PET will increase, CARBIOS' ambition is to become a leading r-PET player by 2035. CARBIOS has extended its international reach to boost its commercial deployment worldwide. Teams in place in key markets are dedicated to identifying business opportunities and establishing commercial partnerships for PET biorecycling technology, with first agreements expected in 2024. To date, CARBIOS is represented in three regions: Europe, North America (including Canada) and Asia (China, Japan, Korea, Singapore, Taiwan, and soon India).

Trützschler expanded their portfolio to become the first full-liner in the preparation of textile waste – from mechanical recycling to the spinning preparation of torn secondary fibers.

The TRUECYCLED solution is the result of their cooperation with the company Balkan Textile Machinery INC.CO. in Turkey, which they announced at the ITMA 2023 trade event in Milan. Since then, Trützschler has received many inquiries for recycling systems.

Success with a systems approach
Recycling systems face significant technological challenges. On average, torn fibers are much shorter than virgin fibers. The percentage share of short fibers in the fiber mass is much higher. Unopened yarn and fabric particles are also difficult to process. Not surprisingly, much academic and practical research is currently conducted to find solutions for these problems. Dr. Georg Stegschuster, a researcher specializing in textile recycling, believes a systems approach is needed. He is working at the Recycling atelier, a model factory for mechanical recycling in Augsburg, Germany, which is committed to delivering the latest technological insights for textile recycling. “A perfect fine-tuning between tearing and spinning preparation is key for obtaining the best possible quality results and avoiding unnecessary fiber shortening,” he says. “This can be achieved if you are in control of both processes – and have the necessary expertise for both processes too.”

Gentle but effective
In some cases, for example, it may be advantageous to have less aggressive settings in the tearing line. This can help avoid unnecessary fiber shortening. The remaining higher share of unopened fabric must then be handled in a high-performance spinning preparation line. This starts with the right blow room configuration for perfect opening, cleaning and blending. A card that is specially designed for recycling materials, such as the new TC 30Ri, can also enable gentle but effective treatment of fibers.

A shortened drafting process is also a must. The integrated draw frame IDF 3 can make this possible. The draft is high enough to provide excellent levelling of the numerous short fibers, but low enough to prevent floating fibers.

Full-liner in mechanical recycling and preparation of textile waste
Trützschler now offers a complete system covering the whole process, from cutting and tearing textile waste through to carding and drawing secondary fibers. Thanks to this holistic approach and Trützschler’s expertise for the whole process, manufacturers can avoid unnecessary fiber shortening.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, announces its membership to Paris Good Fashion, the association that unites over 100 French players in the sector - brands, designers and experts - around their commitment to sustainable fashion. CARBIOS is the first recycling technology supplier to join, demonstrating the importance given to recycling to achieve textile circularity. By contributing its solution for the biorecycling of polyester, the world's most widely used and fastest-growing textile fiber, CARBIOS aims to contribute Paris Good Fashion’s mission, which focuses on concrete actions, best practice sharing and collective intelligence to accelerate change in the fashion industry.

CARBIOS will be particularly involved in the association's project to set up a working group dedicated to the development of a "fiber-to-fiber" industry, one of Paris Good Fashion's top priorities over the next five years. While only 1% of textiles are currently recycled fiber-to-fiber (circular), this working group will identify levers for significantly increasing the share of recycled fibers in the industry.  Polyester currently follows a linear model from which we need to break out: virgin polyester is made from petroleum, and recycled polyester from PET bottles. After use, most of these products end their lives in landfill or incineration. A circular, "fiber-to-fiber" industry will give new life to textiles and reduce the environmental impact associated to their end-of-life management.

The Lenzing Group has created an innovative concept that contributes to the sustainable protection of our glaciers while inspiring collective action for sustainable practices and a circular economy in the nonwovens and textile value chain. The concept, which was artistically staged by the Italian artist Michelangelo Pistoletto, was presented on March 21, 2024, as part of the International Day of Forests celebrations at the Palais des Nations, the headquarters of the United Nations Office at Geneva (UNOG).

The melting of glaciers is being severely impacted by global warming. Geotextiles are used to protect ice and snow. However, the nonwovens used for this are made of fossil-based fibers, which allow microplastics1 to enter the valley via streams and may enter the food chain through small organisms and animals. Nonwovens made from cellulosic LENZING™ fibers, which are biodegradable at the end of their life cycle and can be completely recycled, are the sustainable solution to this problem.

The covering of a small area with the new material made from LENZING™ fibers was tested for the first time during a field test on the Stubai Glacier. Four meters of ice were saved from melting. This was confirmed in a study conducted by the University of Innsbruck and the Austrian glacier lift operators on the Stubai Glacier in Tyrol (Austria). In 2023, the pilot project was successfully extended to all Austrian glaciers used by tourists.

Last year, the project was also awarded first place in the prestigious Swiss BIO TOP Awards for wood and material innovations.

Lenzing takes this innovation project as an opportunity to inspire collaborative action towards sustainable practices and circularity in the textile value chain. Together with a network of innovative partners, Lenzing is working on processing geotextiles into new textile fibers giving them a second life as a garment. The use of geotextiles is usually limited to two years, after which the nonwovens would be disposed of. In the first phase of the pilot project, the recycling of nonwovens made for geotextiles use has been successfully tested and a fashionable “Glacier Jacket” has been produced, showcasing that the recycling of geotextiles is viable. Next to Lenzing, the network includes Marchi & Fildi Spa, a specialist in the field of mechanical recycling, the denim fabric manufacturer Candiani Denim and the fashion studio Blue of a Kind.

Freudenberg Performance Materials (Freudenberg) is showcasing solutions for the automotive, building, apparel, filtration and packaging industries at this year’s Techtextil in Frankfurt am Main from April 23 – 26.

Sustainable nonwoven for car seats
One innovation highlight at Techtextil is a novel Polyester nonwoven material for car seat padding. Also available as a nonwoven composite with PU foam, it is not only easier for car seat manufacturers to handle during the mounting process, but also ensures better dimensional stability as well as providing soft and flexible padding. It has a minimum 25 percent recycled content, for example, by reusing nonwoven clippings and waste, and is fully recyclable. Full supply chain transparency enables customers to trace and verify the content of the nonwoven and thus ensures a responsible production process. The Freudenberg experts will also be presenting several other nonwoven solutions made of up to 80 percent recycled materials that can be used in car seat manufacturing.

Biocarrier for green roofs
Freudenberg is showcasing a sustainable carrier material for green roofs on urban buildings at the trade fair. The carrier is made from polylactide, i.e. from renewable resources. When filled with soil, it provides a strong foothold to root systems, enabling the growth of lightweight sedum blankets that can be rolled out to provide instant green roofs. These roofs not only help counter urban heat, they also improve stormwater management and regulate indoor temperatures.

From textile waste to padding
The company extended its circular thermal wadding product range with the release of comfortemp® HO 80xR circular, a wadding made from 70 percent recycled polyamide from discarded fishing nets, carpet flooring and industrial plastic. Because polyamide 6, also known as nylon, retains its performance characteristics after multiple recycling processes, the fibers can be used again and again to manufacture performance sporting apparel, leisurewear and luxury garments.

Packaging solutions with various sustainability benefits
Freudenberg is also showcasing products for sustainable packaging and filtration solutions. The long-lasting Evolon® technical packaging series is a substitute for disposable packaging used in the transport of sensitive industrial items such as automotive parts. The material is made from up to 85 percent recycled PET. A further highlight at Techtextil are Freudenberg’s fully bio-based solutions for manufacturing dessicant bags. The binder-free material based on bio-fibers is also industrially compostable.
In addition, the experts will be giving trade fair visitors an insight into Freudenberg’s filtration portfolio.

The German Institutes of Textile and Fiber Research Denkendorf (DITF) have modernized and expanded their melt spinning pilot plant with support from the State of Baden-Württemberg. The new facility enables research into new spinning processes, fiber functionalization and sustainable fibers made from biodegradable and bio-based polymers.

In the field of melt spinning, the DITF are working on several pioneering research areas, for example the development of various fibers for medical implants or fibers made from polylactide, a sustainable bio-based polyester. Other focal points include the development of flame-retardant polyamides and their processing into fibers for carpet and automotive applications as well as the development of carbon fibers from melt-spun precursors. The development of a bio-based alternative to petroleum-based polyethylene terephthalate (PET) fibers into polyethylene furanoate (PEF) fibers is also new. Bicomponent spinning technology, in which the fibers can be produced from two different components, plays a particularly important role, too.

Since polyamide (PA) and many other polymers were developed more than 85 years ago, various melt-spun fibers have revolutionized the textile world. In the field of technical textiles, they can have on a variety of functions: depending on their exact composition, they can for example be electrically conductive or luminescent. They can also show antimicrobial properties and be flame-retardant. They are suitable for lightweight construction, for medical applications or for insulating buildings.

In order to protect the environment and resources, the use of bio-based fibers will be increased in the future with a special focus on easy-to-recycle fibers. To this end, the DITF are conducting research into sustainable polyamides, polyesters and polyolefins as well as many other polymers. Many 'classic', that is, petroleum-based polymers cannot or only insufficiently be broken down into their components or recycled directly after use. An important goal of new research work is therefore to further establish systematic recycling methods to produce fibers of the highest possible quality.

For these forward-looking tasks, a bicomponent spinning plant from Oerlikon Neumag was set up and commissioned on an industrial scale at the DITF in January. The BCF process (bulk continuous filaments) allows special bundling, bulking and processing of the (multifilament) fibers. This process enables the large-scale synthesis of carpet yarns as well as staple fiber production, a unique feature in a public research institute. The system is supplemented by a so-called spinline rheometer. This allows a range of measurement-specific chemical and physical data to be recorded online and inline, which will contribute to a better understanding of fiber formation. In addition, a new compounder will be used for the development of functionalized polymers and for the energy-saving thermomechanical recycling of textile waste.
