Carbios and the Fiber-to-Fiber Consortium successfully validate the industrial-scale production of recycled polyester T-shirts made from complex plastic and textile waste.

• Production of high-performance recycled polyester T-shirts enabled by Carbios’ technology
• Full validation across the textile value chain, from pre-industrial recycling to industrial-scale manufacturing
• Identical performance between EnzyTex¹ recycled polyester and virgin polyester
• Three years of collaboration demonstrating the performance of fiber-to-fiber enzymatic recycling at scale

Clermont-Ferrand (France), 29 September 2026 (7:45 am CEST). Carbios (Euronext Growth Paris: ALCRB) announces the successful production of high-quality recycled polyester T-shirts made from complex textile and plastic waste² on European industrial manufacturing lines, in collaboration with the Fiber-to-Fiber Consortium members: Patagonia, PUMA and Salomon.

This achievement demonstrates the ability of Carbios’ biorecycling technology to transform complex waste streams into high-performance textile products meeting the requirements of every stage of industrial processing.

A EUROPEAN ACHIEVEMENT TO SERVE A GLOBAL TEXTILE INDUSTRY

This achievement is the result of close collaboration between Carbios, the members of the Fiber-to-Fiber Consortium, and European industrial partners spanning the entire textile value chain, from polymerization and spinning to knitting, dyeing, and garment manufacturing.

From complex feedstock to finished garment:

Starting from textile waste³ and complex plastic waste, the Carbios process enabled the production of monomers that meet stringent quality and performance standards, comparable to those of petrochemical-derived materials.

These monomers were then repolymerized by Selenis in Portugal to produce more than one ton of high-quality r-PET, marketed under the name EnzyTex, and designed for seamless integration into existing industrial production lines.

The resulting r-PET was converted into yarn on ANTEX’s industrial production lines in Spain, then knitted into Interlock fabric on Henitex’s industrial equipment in France, dyed in an industrial bath by TAD (Teintures et Apprêts Danjoux) in France, and finally turned into garments by ToptexCube (Chamatex Group) in France, with each step carried out under standard industrial conditions.

The resulting fibers demonstrated full compatibility with conventional textile manufacturing processes, while delivering performance characteristics, including mechanical strength, dyeability, and color fastness, equivalent to those of virgin polyester.

Manufactured entirely in Europe, this garment demonstrates the scalability of circular textile manufacturing without compromising on quality.

Benoît Grenot, CEO of Carbios: “This achievement demonstrates that enzymatic recycling meets the highest standards of the textile industry. By converting complex waste streams into high‑purity building blocks for the production of recycled polyester, we are proving that circularity is already an operational reality ready for deployment at industrial scale.”

Howard Williams, Director Global Innovation Apparel & Accessories at PUMA: “Carbios has demonstrated that complex PET waste can be recycled into high-quality polyester fibers under existing industrial conditions and repurposed into high-quality products.”

Guillaume Meyzenq, CEO of Salomon: “The success of this Consortium highlights the power of collective intelligence to tackle one of our industry's most complex challenges. By combining our expertise across the entire value chain, we have demonstrated that circularity for high‑performance textiles is becoming an industrial reality. Together, we have proven that innovative recycling technologies can transform complex waste into high-quality materials without ever compromising on technical performance. For Salomon, this milestone opens significant opportunities to scale circular solutions and shape a more responsible future for outdoor sports apparel.”

A CONSORTIUM PUSHING THE BOUNDARIES OF TEXTILE CIRCULARITY

Initiated by Carbios, the Fiber-to-Fiber Consortium has enabled major progress:

• Validation of enzymatic recycling on complex textile waste streams, including blended and contaminated materials;
• Demonstration that EnzyTex recycled polyester matches the performance of its fossil‑based counterpart;
• Confirmation of the industrial scalability of the Carbios process through the production of 100% recycled polyester products under standard operating conditions;
• European value chain integration.

Beyond the technical performance, Carbios and its partners have demonstrated that high-quality garments can be produced from complex waste streams and that circularity can be achieved without compromising performance.
