From the Sector

For the first time, a piece of clothing is made entirely from textile waste – no bottles, no packaging, no virgin plastic. 100% biorecycled fibers. By developing and industrializing CARBIOS’ enzymatic depolymerization technology to achieve 100% “fiber-to-fiber” recycling, the consortium collectively advances the textile industry's shift towards a circular economy.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, and its “fiber-to-fiber” consortium partners On, Patagonia, PUMA, Salomon, and PVH Corp., parent company of Calvin Klein, unveil the world’s first enzymatically recycled polyester garment made from 100% textile waste using CARBIOS’ pioneering biorecycling technology.

This technological feat contributes to advancing textile circularity when, today, the majority of recycled polyester is made from PET bottles, and only 1% of fibers are recycled into new fibers.  The collective achievement marks an important milestone for the consortium’s ultimate aim of demonstrating fiber-to-fiber closed loop using CARBIOS’ biorecycling process at an industrial scale, and marks an important step forward for the textile industry’s shift towards a circular economy.

A plain, white T-shirt was a deliberate choice to showcase the technological achievement that made its production possible from mixed and colored textile waste.  By using CARBIOS’ biorecycling technology, polyester is broken down using enzymes into its fundamental building blocks which are reformed to produce biorecycled polyester whose quality is on par with oil-based virgin polyester.  Petroleum can now be replaced by textile waste as a raw material to produce polyester textiles, that will in turn become raw materials again, thus fueling a circular economy, with the added benefit of a lower carbon footprint and avoidance of landfill or incineration.

The t-shirt’s production began with all consortium members (On, Patagonia, PUMA, PVH Corp. and Salomon) supplying rolls and production cutting scraps to CARBIOS in Clermont-Ferrand, France.  This textile waste consisted of some mixed blends with cotton or elastane, as well as various treatments (such as durable water repellent) and dyes which render them complex to recycle using conventional methods. The collected waste was deconstructed into its original monomers, PTA and MEG, using CARBIOS’ biorecycling technology at its pilot facility. The resulting monomers were then repolymerized, spun into yarn and woven into new fabric by external partners, demonstrating the seamless integration into existing manufacturing processes.  The resulting sports t-shirt made from 100% textile waste meets the quality standards and sustainability objectives of the apparel brands present in the “fiber-to-fiber” consortium.

CARBIOS’ demonstration plant in Clermont-Ferrand, France, has been up and running since 2021, and its first commercial plant, the world’s first industrial-scale enzymatic PET recycling plant, is currently under construction in Longlaville, France.  In addition, CARBIOS recently announced several letters of intent with PET producers in Asia and Europe, confirming global interest in its biorecycling technology and advancing the international roll-out of its licensing model.

CARBIOS and FCC Environment UK, a recycling and waste management companies in the UK, have signed a Letter of Intent (LOI) to jointly study the implementation of a UK-based plant using CARBIOS’ PET biorecycling licensed technology.  CARBIOS’ biorecycling technology is key to supporting FCC’s continuing goal of contributing to the circular economy by exploring new processes and technologies to produce recycled PET (r-PET) from PET plastic and textiles. For CARBIOS, this LOI confirms interest from the waste management sector, in addition to plastic producers, and would mean a foothold for its technology in the UK.

FCC’s continuing contribution to the UK circular economy
Recycling has plateaued in the UK in recent years, but UK Government policy very much supports a continual move to a more circular economy which FCC Environment supports. Achieving a circular economy however requires innovation and investment to deliver real environmental change. Exploring biorecycling is one way of doing this, so FCC is keen to understand this technology better by seeking an evidence based view on the advantages of using enzymes for the treatment of PET such as lower energy consumption and better circularity of the polymers back into the PET production lines. The depolymerization process developed by CARBIOS also facilitates the recycling of all kinds of PET waste, including problematic fractions such as polyester textiles, into high-quality recycled PET.

UK PET biorecycling plant would process hard-to-recycle waste
In order to tackle the plastic waste crisis, CARBIOS has developed a enzymatic depolymerization technology that enables efficient and solvent-free recycling of PET plastic and textile waste into virgin-like products. CARBIOS has ambitious plans to become a leading technology provider in the recycling of PET by 2035. In addition to the world’s first industrial-scale enzymatic PET recycling plant which is currently under construction in Longlaville, France, this UK-based plant would process PET waste that is currently not recyclable using conventional recycling technologies, such as colored, multilayered or textile waste.

Indorama Ventures Public Company Limited announces its role in the T-REX (Textile Recycling Excellence) Project.

CARBIOS and Zhink Group, specializing in two global industries, PET and textiles, announce the signing of a joint Letter of Intent to build a biorecycling plant in China using CARBIOS’ revolutionary enzymatic depolymerization technology to serve the global market. This agreement officializes collaboration towards a long-term partnership in view of a first licensing contract to build a plant with a minimum annual processing capacity of 50k tons of prepared PET waste and would contribute to accelerating a circular economy for plastic and textiles. China is a key market for CARBIOS, and this agreement would establish a presence in this dominant market.

With 67 million tons of PET produced annually, representing 61% of global production^[1], China is the world's largest PET producer. With regional and global demand for recycled PET growing, China also has the potential to take the lead in recycled PET (r-PET) production. In 2021, 58% of the world’s r-PET was consumed in Asia (with 38% in China^[2]) underscoring this region’s importance both as a major producer and consumer.

Furthermore, China is a key transformer of PET into resins and fibers used in numerous applications in the packaging and textile industries.  Most notably, China is the primary country for transforming PET into fiber, representing 78% of all PET fiber transformation in the world^[3].

For Zhink, the strategic focus is on the development of two global industries, PET and textiles, and to be a leader with sustainable competitiveness. Zhink is a major actor within the PET market with an annual production of 3 million tons of PET, serving domestic and global markets. CARBIOS has developed a enzymatic depolymerization technology that enables efficient and solvent-free recycling of PET plastic and textile waste into virgin-like products. The initial agreement between the two groups would allow Zhink to increase its recycled PET capacities and meet its sustainable competitiveness objectives by offering r-PET from enzymatic recycling: a circular recycling solution that can process all types of PET waste including hard-to-recycle waste (such as opaque and colored bottles, multilayer food trays and textile waste) while reducing CO2 emissions by 57%^[4] compared with virgin PET production. For CARBIOS, this agreement marks a significant step in the deployment of its technology worldwide and roll-out of its licensing model to achieve its ambition to become a leading technology provider in the recycling of PET by 2035. This Asia-based plant under license by Zhink would come in addition to the world’s first industrial-scale enzymatic PET recycling plant which is currently under construction in Longlaville, France.

CARBIOS and TOMRA Textiles, a tech venture set up by the sorting technology company TOMRA, announce the signing of an agreement to collaborate on establishing an efficient stream in Northern Europe from textile waste collection, sorting and preparation to recycling using CARBIOS’ enzymatic depolymerization technology at its first commercial plant currently under construction in Longlaville, France

The monomers obtained will be used to produce recycled polyester (r-PET) fiber, closing the loop for polyester textile circularity.

The innovations from both TOMRA Textiles and CARBIOS contribute to addressing critical gaps in the value chain and significantly increase textile-to-textile recycling from its current rate of 1%¹. By accelerating a circular economy for polyester, a sustainable alternative to incineration or landfill is made available.

TOMRA Textiles is on a mission to close the gap in textile circularity, by contributing to designing and scaling textile sorting plants. Under this partnership agreement, TOMRA Textiles will explore specific, tangible measures to enable the preparation of post-consumer polyester waste for biorecycling according to CARBIOS’ specifications.

CARBIOS' biorecycling technology involves breaking down polyester fibers into their basic components using enzymes, which are then used to produce high-quality recycled PET materials such as fibers for the textile industry. The breakthrough collaboration with TOMRA will redirect the challenging PET fraction of polyester textile waste towards biorecycling, showcasing a mutual dedication to pioneering recycling solutions for a circular economy.

A joint venture between Salvation Army Trading Company (SATCoL) and Project Plan B, known as Project Re:claim, has begun operations in Kettering, Northamptonshire - the first commercial-scale, post-consumer polyester recycling plant of its kind that provides a solution to the issue of polyester textile waste.

The plant will recycle post-consumer garments and other textiles, and supply the raw material back into the fashion and textiles industries.

The machine was installed in January 2024 and is now fully operational, with polyester pellets being produced from polyester waste. The plant is on track to recycle 2,500 tonnes of unwanted polyester this year, with a further 5,000 tonnes in year 2, and creates polyester pellets which can be spun into yarn for use in textiles along with other industrial applications. The pellets are expected to be integrated into the manufacturing processes of new products later this year.

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.

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.

Eastman announces a partnership with Patagonia to address textile waste.

The outdoor apparel company teamed up with Eastman to recycle 8,000 pounds of pre- and post-consumer clothing waste, which Eastman processed through its molecular recycling technology. The process involves breaking down Patagonia’s unusable apparel into molecular building blocks that Eastman can use to make new fibers.

"We know apparel waste is a major problem, and consumers increasingly want better, more sustainable solutions when their most loved clothing reaches the end of its life," said Natalie Banakis, materials innovation engineer for Patagonia.

"Our collaborations show the world what’s possible when it comes to sustainability,” said Carolina Sister Cohn, global marketing lead for Eastman textiles. “We have the technology to make the textiles industry circular, and we know it requires collaboration with innovative brands to make circular fashion possible. This is only the beginning, and we look forward to more collaborations throughout 2024."
