The World's first 100% biorecycled fiber clothing unveiled
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., the 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 a 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, which 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, including 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 (Purified Terephthalic Acid), and MEG (Monoethylene Glycol), 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.
