Canopy, a not-for-profit environmental organization dedicated to protecting forests, species, and climate, welcomes the agreement between Lenzing and Renewcell.
“Accelerating the transition to low-impact, circular production is the challenge of the decade for the fashion industry. That is why this partnership between Renewcell and Lenzing is so refreshing – it will bring low-carbon Next Gen solutions to market at scale,” exclaimed Nicole Rycroft, Executive Director of Canopy. “With the climate and biodiversity clocks ticking, the race to circularity is one we need all companies to win.”
 
It is an essential part of Lenzing’s corporate strategy and ambitious sustainability targets to become a true champion of circularity and to offer TENCEL™ and LENZING™ ECOVERO™ branded specialty textile fibers with up to 50 percent post-consumer recycled content on a commercial scale by 2025. To reach this goal Lenzing partners with recycling pioneers like Renewcell.
Circulose® originates 100 per cent from textile waste, like old jeans and production scraps, and turns into dissolving pulp. It transforms textile waste and production scrap into new high-quality textile products.

• Lenzing again recognized for sustainable sourcing, innovation and transparency
• Lenzing achieves the highest category for the third time already

The Lenzing Group achieved first place in the “Hot Button Ranking” of the Canadian non-profit organization Canopy, thus confirming its leading role in the areas of sustainability and responsible wood and pulp sourcing. Lenzing can also once again celebrate a dark green shirt, synonymous with the highest category.

In this ranking, which receives a lot of attention in the textile and apparel industry, Canopy evaluates the world’s 34 largest producers of cellulosic fibers in terms of their sustainable wood and pulp sourcing, their efforts with regard to the use of alternative raw materials and their achievements in the protection of ancient and endangered forests. Resource preservation is a key element of Lenzing’s corporate strategy and at the core of its innovation agenda. The sustainable production of TENCEL™, VEOCEL™ and LENZING™ ECOVERO™branded specialty fibers is based on these principles.

Promoting the circular economy
With its REFIBRA™ and Eco Cycle technologies, Lenzing offers solutions for transforming the textile and nonwovens industries towards a circular economy. In line with its vision for the circular economy, “We give waste a new life. Every day.” Lenzing is driving the industry toward a full circular economy by striving to give waste a new life in all aspects of its core business and developing circular solutions together with potential partners inside and outside the current value chain. A milestone on this path is the cooperation with the Swedish pulp producer Södra. The two global market leaders, who have been proactively promoting the circular economy in the fashion industry for many years, are joining forces to give the topic a further boost and make a decisive contribution to solving the global textile waste problem by making fibers from post-consumer textiles.

Today, Lenzing offers lyocell fibers made from 30 percent recycled cotton waste. The company aims to launch lyocell, modal and viscose staple fibers with up to 50 percent recycled post-consumer content on a commercial scale by 2025 and to develop a new circular business model by closing the loops for post-consumer waste. By 2025, the company plans to enter into further partnerships with 25 key supply chain companies.

Fibre Extrusion Technology Limited (FET) of Leeds, England has installed a FET-200LAB wet spinning system at the University of Manchester which will play a major part in advanced materials research to support sustainable growth and development.

This research programme will be conducted by The Henry Royce Institute, which operates as a hub model at The University of Manchester with spokes at other leading research universities in the UK.

The Henry Royce Institute identifies challenges and stimulates innovation in advanced UK materials research, delivering positive economic and societal impact. In particular, this materials research initiative is focused on supporting and promoting all forms of sustainable growth and development.
These challenges range from biomedical devices through to plastics sustainability and energy-efficient devices; hence supporting key national targets such as the UK’s zero-carbon 2050 target.

FET-200 Series wet spinning systems complement FET’s renowned range of melt spinning equipment. The FET-200LAB is a laboratory scale system, which is especially suitable for the early stages of formulation and process development. It is used for processing new functional textile materials in a variety of solvent and polymer combinations.

In particular, the FET-200LAB will be utilised in trials for a family of fibres made from wood pulp, a sustainable resource rather than the usual fossil fuels. Bio-based polymers are produced from biomass feedstocks such as cellulose and are commonly used in the manufacture of high end apparel. The key to cellulose and other materials like lyocell and viscose is that they can be recycled, treated and fed back into the wet spinning system for repeat manufacture.

Established in 1998, FET is a leading supplier of laboratory and pilot melt spinning systems with installations in over 35 countries and has now successfully processed more than 35 different polymer types in multifilament, monofilament and nonwoven formats.

• made out of recycled PET flakes and recyclable again
• suited for finishing recycled yarns and fabrics
• moisture management in sports and active wear

For the sustainable use of resources, the CHT Group has developed the product ARRISTAN rAIR, according to the principles of the circular economy. Here, plastic waste is converted into a valuable textile finishing product to achieve, for example, optimal moisture management in sports and active wear. Other areas of application include socks and tights in the clothing sector, filtration media and nonwovens in the technical textiles sector, and pillows and curtains in home textiles.

Since ARRISTAN rAIR is made out of recycled PET flakes, it is suited for finishing recycled yarns and fabrics which are subsequently recyclable again.

The hydrophilizing agent ARRISTAN rAIR is characterized by its fast-drying properties in combination with excellent soil release and thermoregulation. It therefore offers, especially in the field of functional textiles, optimal functionalities for high-quality and durable sportswear.

The Swedish textile-to-textile recycling company Renewcell has signed a Letter of Intent with Eastman, a leading US cellulosic acetate fiber producer, for a collaboration to develop Naia™ Renew ES yarns sourced from Circulose®, Renewcell’s 100% recycled textile raw material. The agreement is Renewcell’s first with a US-based fiber producer and an important step in developing the first acetate-based applications to use Circulose® feedstock.

”Eastman considering Circulose® as a feedstock in the production of a premium yarn like Naia™ Renew reflects very well on the Renewcell team’s ability to work with partners to adjust and optimize our product for new fiber applications. This agreement signals an acceleration of our joint efforts to bring Naia™ Renew ES yarns derived from Circulose® to market. I look forward to working alongside Eastman in making fashion circular.” comments Patrik Lundström, CEO of Renewcell.

Ruth Farell, GM of Eastman Textiles says: ”we are thrilled to collaborate with a pioneeer such as Renewcell to lower our reliance on virgin feedstocks, redefine the essence of textile waste and close the loop within the textiles industry. This collaboration is at the heart of our strategy to launch a portfolio of products with increased recycled content”

To further advance the system, the Global Organic Textile Standard (GOTS) is significantly raising the requirements for GOTS-certified gins, to ensure transparent and traceable processing for organic textiles from field to finished product:

1. GOTS is introducing a compulsory farm-gin registry for all farms and farm groups whose certified raw material enters the GOTS system, including information on farm yields. The registry will be implemented progressively, starting in India.
2. Raw cotton is not allowed to travel more than 500 km from the farm to the certified gin. The shorter trade chain protects vulnerable points and optimises the process for buyers.  
3. Increase of unannounced audits of gins where there is a high perception of risk.

These new requirements are added to the numerous checks and balances which are already performed throughout every processing stage. Seed cotton entering the GOTS supply chain is tested for the presence of genetically modified organisms according to the applicable ISO protocol. GOTS-approved Certification Bodies (CBs) include further testing (such as pesticide residue) and are fully authorised to reject material that does not meet GOTS requirements. Additionally, before certification bodies issue a Transaction Certificate (TC), GOTS requires that a thorough assessment takes place, including a plausibility check in the form of volume reconciliation.

To strengthen integrity and traceability, GOTS also stipulates that the Farm TC number appears on the first GOTS TC at the ginning plant, which is the first step for cotton in the GOTS supply chain. The TC must state the origin for raw material, including region, state, and province. This effectively traces material back to the field and adds another layer of accountability to GOTS-certified fibre. It also supports all buyers in their purchasing decisions.

GOTS is not only improving its own system but also coordinating efforts with other key players to support the integrity of organic textiles. As GOTS provides certification of first processing stages to Textile Exchange's Organic Content Standard (OCS), GOTS and TE discussed new requirements for OCS while they were being developed. GOTS supports these requirements as they provide a dual protection shield for materials entering the GOTS or OCS supply chains, at the same time maintaining necessary data privacy. The new requirements will help increase traceability and transparency throughout the organic textile sector which are among the main objectives of GOTS. There are no changes necessary to the requirements of GOTS regarding any of the new OCS rules.

After two years of joint collaboration and research the Swiss Textile Recycling Project “Texcircle” comes to an end. Partners and stakeholders have worked on the vision of a textile cluster where materials flow in circular loops. The goal of the project was to develop high-quality yarns and products incorporating such a large amount of recycled textiles as possible. In the end, several product prototypes from carpets, socks, and curtains to pullovers, padding and accessories have been developed with at least 50 % recycled fiber up to 80 % recycled fibers and yarns.

Europe has a waste problem of 7.5 million waste of which only 30-35 % is collected and less than 1 % of the textile and clothing worldwide is recycled into textiles and clothing again. It is as well found that around 80 % of the impact of a textile product lies in the design.

Together with the design research expertise of the Lucerne University of Applied sciences and arts, the spinning expertise of Rieter and the sorting and collection expertise of Texaid, systems should be created where products of high quality can be produced of recycled fiber. On board were the expertise of further Cluster partners of Brands, Retailers, and the public sector to see how a joint Cluster and system coukld be established.

The Project Texcircle and cluster is led by the Lucerne University of Applied Sciences and Arts – Art  & Design, and in collaboration with Coop, Rieter, Jacob Rohner AG, Ruckstuhl AG, TEXAID as well as workfashion.com ag. Furthermore, Bundesamt für Zivildienst ZIVI, NIKIN AG, and Tiger Liz Textiles are supporting the project. The project is funded by Innosuisse.

Furthermore, collaboration partners from all over Europe contributed to the project to enable these prototypes and systems.

Through joint developments from the design, the collecting, sorting trials, tearing, and spinning trials until the actual production trials and product testing. The partners were able to recycle 2.5 Tons of pre-and post-consumer textile waste into product prototypes with a promising commercial interest. From socks, west, and pullovers to non-woven felts and accessories to carpets and curtains. Through our 2 years of collaboration, the teamcame across several hurdles in the textile recycling value chain which could be tackled. This was a proof of concept that a circular system is possible and the industry now has to enable this at full scale.

The textile industry is the third largest consumer of plastics. While growth rates in the production of fibres and textiles are high, the circular economy has hardly become established in this segment. The EREMA Group is now intensifying development of recycling solutions for this application with their new fibres and textiles business unit. Currently, the focus is on PET fibre materials from fibre production and subsequent processing steps. Technologies for recycling mixed fibre textiles from textile collection sources are to follow in a follow-up project phase.

"With EREMA's VACUREMA® and INTAREMA® technology and PURE LOOP's ISEC evo technology, our company group already has an extensive range of machines for fibre and PET recycling applications. For ecologically and economically sound recycling, however, new technological solutions are needed to use the recycled fibres in higher-value end applications and to achieve a functioning circular economy," explains Wolfgang Hermann, Business Development Manager Application Fibres & Textiles, EREMA Group GmbH. The initial focus will be on PET, regarded as a key material for the production of synthetic fibres. The aim is to find recycling solutions that allow PET fibre materials to be prepared for reuse in PET fibre production processes. This is a significant step for the circular economy because PET fibres in textiles account for about two-thirds of the total volume of PET.

In this development work, the EREMA Group can build on existing know-how. Proven recycling technologies have been combined with a new IV optimiser. "This extends the residence time of the PET melt, which is particularly necessary in fibre recycling to efficiently remove spinning oils. Our recycling process also increases the IV value of the PET melt after extrusion back to the specific level that is essential for production of the fibre," explains Hermann. Waste PET fibre from production processes can therefore be further processed into rPET filament fibre, carpet yarn and staple fibre.

Fibre test centre with plant to test customers' materials
In order to accelerate development work, EREMA opened its own fibre test centre a few months ago, where a cross-company team is working on recycling solutions for fibre-to-fibre applications.

The first Cradle to Cradle Certified^® clothing collection is on the market one year after the collaboration platform for Swiss textile labels was launched. The Circular Clothing cooperative has succeeded, in close cooperation with European suppliers, in gaining access to circular materials and equipment and using this for the Black Denim Collection by the ethical fashion label “the Blue suit”. An important step for the cooperative, which receives funding from the Migros Pioneer Fund, is the development of an online assessment tool which can be used to help check the readiness of textile labels to operate in a circular manner.

The black denim was developed by a renowned manufacturer in Italy. Since no toxic chemicals are used in the production process, this denim is safe for biological cycles and Cradle to Cradle Certified^® Gold. Cradle to Cradle Certified^® Gold certified material by the Swiss company OceanSafe was used for the lining of the jacket. Special innovative design elements and production processes, such as the printed lining, also meet the stringent Cradle to Cradle Certified^® Gold requirements. Currently, 1% of the material of the Black Denim Collection is Cradle to Cradle Certified® Bronze. In the next few months, this percent and thus also the whole garments should reach the gold level.

The Cradle to Cradle^® certification is based on the following five principles: Material Health, Product Circularity, Clean Air & Climate Protection, Water & Soil Stewardship, and Social Fairness. Depending on the extent to which all of these criteria are met by the manufacturing process, there are various levels of certification from bronze to silver, gold and platinum.

Viscose speciality fibres manufacturer Kelheim Fibres partners with TextileGenesisTM, a traceability platform that creates radical transparency from fibre-to-retail and ensures authenticity d provenance of sustainable textiles against generics.

“Our wood-based fibres are an environmentally friendly basis for sustainable textiles - it's just that consumers often don't know what's behind their garments. But they need to know it’s in their hands to minimise the ecological footprint of the textile industry. Transparency and traceability are the foundation that enables consumers to make informed decisions.”, says Dr. Marina Crnoja-Cosic, Director New Business Development at Kelheim Fibres.

TextileGenesisTM uses blockchain technology to track and verify the use of sustainable fibres all the way from fibre to garment. A digital fibercoin ensures transparency and reliability throughout the entire production line and beyond.

Amit Gautam, Founder & CEO at TexileGenesisTM:"Fashion and textile value chain is undergoing major transformation driven by sustainable materials, shifting consumer demand for sustainable products, and increasingly stringent regulations on transparency. Great to see Kelheim moving the industry forward by actively participating in the traceability journey."
