From the Sector

At this year's JEC World, STFI will be presenting highlights from carbon fibre recycling as well as a new approach to hemp-based bast fibres, which have promising properties as reinforcement in lightweight construction.

Green Snowboard
At JEC World in Paris from 5 to 7 March 2024, STFI will be showcasing a snowboard from silbaerg GmbH with a patented anisotropic coupling effect made from hemp and recycled carbon fibres with bio-based epoxy resin. In addition to silbaerg and STFI, the partners Circular Saxony - the innovation cluster for the circular economy, FUSE Composite and bto-epoxy GmbH were also involved in the development of the board. The green snowboard was honoured with the JEC Innovation Award 2024 in the “Sport, Leisure and Recreation” category.

VliesComp
The aim of the industrial partners Tenowo GmbH (Hof), Siemens AG (Erlangen), Invent GmbH (Braunschweig) and STFI united in the VliesComp project is to bring recycled materials back onto the market in various lightweight construction solutions. The application fields "Innovative e-machine concepts for the energy transition" and "Innovative e-machine concepts for e-mobility" were considered as examples. On display at JEC World in Paris will be a lightweight end shield for electric motors made from hybrid nonwovens - a mixture of thermoplastic fibre components and recycled reinforcing fibres - as well as nonwovens with 100% recycled reinforcing fibres. The end shield was ultimately manufactured with a 100% recycled fibre content. The tests showed that, compared to the variant made from primary carbon fibres using the RTM process, a 14% reduction in CO₂ equivalent is possible with the same performance. The calculation for the use of the prepreg process using a bio-resin system shows a potential for reducing the CO₂ equivalent by almost 70 %.

Bast fibre reinforcement
To increase stability in the plant stem, bast fibres form in the bark area, which support the stem but, in contrast to the rigid wood, are very flexible and allow slender, tall plants to move in the wind without breaking.A new process extracts the bast bark from hemp by peeling.The resulting characteristic values, such as tensile modulus of elasticity, breaking strength and elongation, are very promising in comparison with the continuous rovings made of flax available on the market.The material could be used as reinforcement in lightweight construction.At JEC World, STFI will be exhibiting reinforcing bars that have been processed into a knitted fabric using a pultrusion process based on bio-based reinforcing fibres made from hemp bast for mineral matrices.

Haelixa, the trailblazer of physical traceability solutions, has partnered with Trudel Silk, a market leader for sustainable organic and recycled silk products. This collaboration brings traceability and transparency to silk production.

Silk is one of the finest and smoothest fabrics; the better the quality of the silk, the more luxurious it feels to the touch. To create the best quality silk, the conditions for mulberry cultivation must be up to the highest standards. A healthy micro-ecosystem in the fields translates to top-grade silk cocoon quality. At Trudel, this is the environment they have created for the vertical integration of their business. Trudel aims to succeed at every stage of the process, which can only be accomplished through the active involvement and visible cooperation of all market players. These players include farmers, reeling mills, twisting/spinning mills, weaving mills, dyeing and printing mills, and brands. They are involved in every step, from the cultivation of mulberry trees to the production of silk fabrics.

Haelixa and Trudel have collaborated to improve silk’s robust and consistent traceability. As the demand for validation of the silk value chain increases, they have partnered with groups from Italy and Asia to develop a unique solution that uses DNA markers to trace the entire supply chain of silk production. This innovative approach ensures each silk product’s ethical sourcing.

The silk fibers used in their spun silk yarns are marked with a specific DNA per farm set selected by Trudel. Throughout the supply chain, samples of yarn, fabrics, and finished products undergo testing to verify the presence of original silk fibers. Based on the reporting, the brand can trace the finished accessories or garments to Trudel.

Celanese Corporation, a specialty materials and chemical company, and Under Armour, Inc., a company in athletic apparel and footwear, have collaborated to develop a new fiber for performance stretch fabrics called NEOLAST™. The innovative material will offer the apparel industry a high-performing alternative to elastane – an elastic fiber that gives apparel stretch, commonly called spandex. This new alternative could unlock the potential for end users to recycle performance stretch fabrics, a legacy aspect that has yet to be solved in the pursuit of circular manufacturing with respect to stretch fabrics.

NEOLAST™ fibers feature the powerful stretch, durability, comfort, and improved wicking expected from elite performance fabrics yet are also designed to begin addressing sustainability challenges associated with elastane, including recyclability. The fibers are produced using a proprietary solvent-free melt-extrusion process, eliminating potentially hazardous chemicals typically used to create stretch fabrics made with elastane.

NEOLAST™ fibers will be produced using recyclable elastoester polymers. As end users transition to a more circular economy, Celanese and Under Armour are exploring the potential of the fibers to improve the compatibility of stretch fabrics with future recycling systems and infrastructure.

In addition to the sustainability benefits, the new NEOLAST™ fibers deliver increased production precision, allowing spinners to dial power-stretch levels up or down and engineer fibers to meet a broader array of fabric specifications.

As part of the "RUDOLSTÄDTER KUNSTSTOFFTAGE" series, the TITK - Thüringisches Institut für Textil- und Kunststoff-Forschung e.V. invites you to the symposium "All about cellulose: How we can use a native polymer for intelligent, innovative and sustainable products".

In their presentations, speakers from industry and research will highlight the potential and diverse applications of the sustainable platform polymer cellulose for clothing, hygiene and medical textiles, battery and storage technology or as a meltable material for 3D printing.
The conference language is English.

The conference is aimed at textile manufacturers and processors as well as materials scientists and SMEs from the industry in general. As in previous years, there will be the opportunity to visit the technical centres and laboratories of the business-oriented research institute.

Event details and registration options can be found under DATES.

CARBIOS, a pioneer in the development and industrialization of biological technologies to reinvent the life cycle of plastic and textiles, has received an initial payment of €1.2 million from the French Agency for Ecological Transition (ADEME) for the OPTI-ZYME research project, carried out in partnership with INRAE2, INSA3 and CNRS4 via the TWB5 joint service and TBI6 research units, a project co-funded by the French State as part of France 2030 operated by ADEME. With CARBIOS' aim to optimize and continuously improve its unique enzymatic PET depolymerization technology, the 4-year7 OPTI-ZYME project aims to investigate the scientific and technical levers for improving the competitiveness of the process, optimizing the necessary investments and reducing its environmental footprint.

This collaborative R&D program focuses on the technical and economic optimization of process stages, while preserving the quality of the monomers obtained. These optimizations, new developments and the exploration of innovative solutions should enhance the technology's flexibility with regards to incoming waste. Raw materials could come from different sources that are currently rarely or not recycled, notably food trays and textiles, or a mix of incoming materials. It also aims to limit input and water consumption, as well as regenerate or reduce co-products and ultimate residual waste. Finally, it seeks to support enzyme optimization to maximize the process’ economic profitability and competitiveness.

The project therefore aims to achieve an overall improvement in performance, combining efficiency, quality and environmental sustainability, to benefit the Longlaville plant which is currently under construction, and future licensed plants.

In May 2023, CARBIOS, the project leader and coordinator, announced that it had been awarded a total of €11.4M in funding by the French State as part of France 2030, operated by ADEME, including €8.2M directly for CARBIOS (€3.2M in grants and €5M in repayable advances) and €3.2M for its academic partners INRAE, INSA and CNRS (via the TWB mixed service and TBI research units). This funding, which is made up of grants and repayable advances, will be paid out in several instalments over the course of the project, including an initial instalment of 15%, equivalent to €1.2 million, received by CARBIOS on 5 December 2023. The first Monitoring Committee with ADEME for the first key stage of the project will be held in February 2024 to validate the granting of the second instalment of funding.

This project 2282D0513-A is funded by the French State as part of France 2030 operated by ADEME.

Eastman Naia™ Renew cellulosic fiber received Global Recycled Standard (GRS) certification on December 13. This certifies Naia™ Renew recycled content, chain of custody, social and environmental practices, and chemical restrictions.

Textile Exchange, a global non-profit for sustainable change in the fashion and textile industry, manages the GRS certification process. Certification is achieved through an audit from independent third-party certifying body SCS Global Services and applies to the full supply chain and addresses traceability, environmental principles, social requirements, chemical content and labeling.

"We’re honored to add GRS certification to our list of Naia™ certifications that support our sustainability goals,” said Claudia de Witte, sustainability leader for Eastman textiles. “Third-party certifications help us build our brand trustworthiness. It’s our goal to make sustainable textiles available to all, and we do that by building trust with our customers and collaborators. This certification adds even more credibility to our fibers and our sustainability story, which we’re proud to share.”

In June 2023, Textile Exchange made an important announcement regarding its Alternative Volume Reconciliation (VR2) policy, which broadened the range of chemical recycling technologies eligible for mass balance. Notably, this expansion now encompasses gasification, the technical description of Eastman’s molecular recycling technology known as carbon renewal technology. Eastman collaborated with Textile Exchange and other stakeholders to educate the industry about the value and contribution of its molecular recycling technology. This policy update is critical for Eastman because it allows the company’s innovative material-to-material recycling technology to be audited for GRS certification.

Molecular recycling technologies at Eastman break waste down into its molecular building blocks allowing the materials to be used in new materials that are indistinguishable from non-recycled materials. By expanding the GRS to include gasification, the global standard now allows for a broader approach to making sustainable textiles accessible to everyone.

In recent years, the textiles industry has shifted toward circular materials to help tackle one of the largest challenges facing the planet: waste pollution, especially textile waste. Eastman molecular recycling is complementary to mechanical recycling and is a solution for hard-to-recycle waste material, including textiles, which are impacted by factors like fiber blends, chemicals and additives.

Naia™ Renew is produced from 60% sustainably sourced wood pulp and 40% GRS-certified* waste materials that would otherwise be destined for landfills through Eastman's patented molecular recycling technology. The certification verifies the processes of chemical recycling, concentrating, extrusion, and spinning of the undyed yarns and fibers.

Carbios was one of eight beneficiaries selected to present the progress of its industrial project in the presence of the President of the French Republic on the occasion of the two-
year anniversary of the launch of the France 2030 investment plan. Carbios is receiving €42.5 million in public funding (€30 million from the State as part of France 2030 and €12.5 million from the Grand-Est Region) for the construction of the plant for the enzymatic depolymerization of PET. Carbios is an emblematic example of the France 2030 initiative to support innovative projects that contribute to reindustrialization through innovation in strategic sectors, such as recycling. This plant, located in Longlaville in the Grand-Est Region, will be Carbios' first industrial site. Construction has just begun.

Carbios' technology enables PET circularity and provides an alternative raw material to virgin fossil-based monomers, allowing PET producers, waste management companies, public entities, and brands to have an efficient solution to meet regulatory requirements and fulfill their own sustainability commitments. The plant will have a processing capacity of 50,000 tons of post-consumer PET waste per year (equivalent to 2 billion colored PET bottles, 2.5 billion PET trays, or 300 million T-shirts) and will address waste with little or no value such as colored PET bottles, food trays, and textiles. The plant will create 150 direct and indirect jobs in the region. In October 2023, Carbios obtained the building permit in 10 months (the average duration in France is 17 months) and the site operating permit, allowing construction to begin. The plant is currently under construction in Longlaville in the Grand-Est Region.

HeiQ AeoniQ™ becomes an active brand partner of the Canopy initiative with eleven other companies to address the growing climate and biodiversity crises by committing to keep Ancient and Endangered Forests out of our man-made cellulosic fiber supply chain.

The commitments that HeiQ AeoniQ™ is making are part of solutions-driven non-profit Canopy’s Pack4Good and CanopyStyle initiatives which currently represent collectively 950 brand partners. Together, the initiatives are shifting supply chains away from vital forests to low-impact, circular Next Gen Solutions.

“We must rapidly replace oil-based polyester in the textile industry causing microplastics, global warming, landfill and ecosystem degradation. Cellulose is the most abundant biopolymer in the world and is best suited to replace polyester. However, we must pay attention to cellulose feedstock sources. Our forests, a potential cellulose feedstock, are one of the most important solutions to addressing the effects of climate change. Approximately 2.6 billion tons of carbon dioxide, one-third of the CO₂ released from burning fossil fuels, is absorbed by forests every year. Around 12.5% of global greenhouse gas emissions (5-10 GtCO₂e annually) come from deforestation. We are losing forests at an alarming rate. Every year, around 10 million hectares of forests globally are destroyed. We need immediate action to increase forests again. Canopy is our go-to partner to replace polyester with circular & sustainable cellulose feedstock for our innovative HeiQ AeoniQ™ fiber revolution.” said Carlo Centonze, HeiQ Group CEO.

Paper packaging is also a key driver of forest loss globally, as 3.1 billion trees are cut down annually to produce the boxes and bags in which products are packaged and shipped. Paper packaging production has increased by 65% over the past two years.

“The range of companies and sectors represented in today’s announcement reflects the breadth of market response to the growing climate and biodiversity crises and intensifying supply chain disruptions,” said Nicole Rycroft, Founder and Executive Director of Canopy. “Today’s brand partners add significant momentum to global conservation efforts and the movement to transform ‘take, make, waste’ supply chains to be lower-impact and Next Gen.”

Today, as part of Pack4Good, HeiQ AeoniQ™ committed to:

• Eliminate Ancient and Endangered Forests from our paper packaging supply chain.
• Reduce material use through design innovation.
• Maximize recycled content.
• Explore and scale alternative Next Gen fibers (such as agricultural residues).
• Where virgin fiber is necessary, use FSC-certified fiber.

The innovative company RUDOLF has been honoured for its outstanding achievements in the field of sustainability and environmental protection and has won the coveted Responsible Care Federal Competition 2023 in the category SME.

The award was presented as part of a competition organised by the German Chemical Industry Association (VCI). Responsible Care is a voluntary initiative of the chemical industry. Its aim is continuous improvement in the areas of environmental protection, health and safety. Chemical companies and associations in more than 50 countries support the initiative. The award-winning project of the innovative company RUDOLF impressed the jury with its pioneering technology, which reduces CO2 emissions by up to 99.9 % compared to conventional cooling systems. „The project uses near-surface geothermal energy for industrial cooling - according to the motto „Efficiency First“ the most efficient way has been chosen!“ - Jury statement
 
TerraCool‘s winning system uses near-surface geothermal energy as the most natural form of cooling. It utilises the constant temperature of around 10°C at a depth of around 10 metres below ground. A specially developed heat exchanger system takes advantage of this natural cooling effect. In the future, it will be used to cool chemical production processes at RUDOLF. The main advantage of this technology is that it is CO₂ neutral. The technology is highly efficient and consumes only 0.1 % of the electricity used by conventional cooling systems.  By using natural resources, the system reduces CO₂ emissions by up to 99.9 % compared to conventional cooling systems, resulting in a very presentable carbon footprint. Another impressive aspect is its high energy efficiency. With just 1 kW of electrical energy, the system generates up to 600 kW of cooling capacity, thanks to the use of a highly energyefficient circulating pump system. Energy is, and will continue to be, a valuable „raw material“ for our industry and one that we need to manage carefully. The system is self-contained and has no contact with groundwater. No environmentally harmful refrigerants or antifreeze are required. With this technology, RUDOLF has made a pioneering contribution to the climate-neutral transformation of the economy, proving that innovative solutions can go hand in hand with environmental protection and sustainability. The Responsible Care award recognises the company‘s commitment to a greener future.
