Recycling

Much of India's textile waste is too mixed or contaminated to resell, reuse or recycle. Asha Singhal, Director, Nature of Fashion at The Biomimicry Institute, explains what the fourth Nature of Fashion pilot will target, what India can take from earlier work in Ghana, the Netherlands and Germany, and why local conditions must shape the technologies tested.

The quality of commercially available yarns made from recycled cotton will be mapped and physically validated under a cross-industry project that Fashion for Good has launched with partners from across the cotton value chain. The project will give the industry a data-backed overview of how quality, price and recycled content intersect.

India generates an estimated 7.8 million tonnes of textile waste a year, and much of the low-value, mixed or contaminated fraction has no commercially viable end-of-life pathway. Shruti Goel, Chief Executive Officer of Upaya Social Ventures, explains how a new accelerator run with The Biomimicry Institute will support decomposition enterprises while tying their growth to dignified, verifiable employment.

Fashion has spent years refining materials, launching repair pilots and testing take-back schemes, yet circularity still functions as a set of separate initiatives rather than a working system. The more consequential test comes after the sale, when the product meets the consumer, the retail conversation and the wider infrastructure that surrounds continued use, repair and resale.

The environmental debate around fast fashion has long turned on a single question: cotton or polyester, which is greener. A comprehensive lifecycle assessment now suggests the question itself was misplaced. Tracing garments from raw material through disposal, the research finds transport mode and garment lifespan reshape emissions by margins that no fibre substitution can match.

Advanced textiles that monitor health, motion and environment are moving out of laboratories and toward retail shelves. These hybrid garments carry conductive metals, mixed polymers and embedded electronics that existing recycling systems cannot handle. Regulation, disassembly standards and material transparency must arrive before commercial rollout begins in earnest across global consumer markets and outpaces the infrastructure meant to contain it.

Completed case studies from a multi-year programme have shown that biological decomposition processes, including enzymatic hydrolysis, bacterial fermentation, and microbial activity, can convert discarded textile waste into biodegradable and biocompatible materials. Pilots in Ghana, the Netherlands, and Germany have mapped a pathway that routes fashion's discards through breakdown processes rather than landfill or incineration.

Stretchy clothing could soon be recycled as easily as plastic bottles, thanks to a new elastic yarn that rivals spandex yet melts down and respins into fresh thread. Built entirely from one plastic family, it needs no chemical separation, and could support more circular production and recovery across the textile industry.

A new test material developed by the National Institute of Standards and Technology aims to strengthen fibre identification in textile recycling, addressing a gap that limits sorting accuracy and domestic supply chain recovery. The material supports AI-enabled sorting tools and gives labs a shared benchmark, with more than half of all textiles currently suitable for recycling but most going unrecovered.

Textile recycling has spent years trapped between ambition and evidence, with fibre-to-fibre promises rarely translating into commercial deployment. The recent Textiles Recycling Expo in Brussels marked a shift. Automated sorting, chemical and mechanical recycling, and Digital Product Passports moved from concept to working infrastructure, forcing an uncomfortable question about who will actually buy the output.
