Biological decomposition processes have shown they can convert discarded textile waste into biodegradable and biocompatible materials. Completed case studies from The Biomimicry Institute's Nature of Fashion: Design for Transformation programme have mapped a staged pathway from textile discard to biological recovery, positioning decomposition as a parallel strategy to conventional recycling rather than a fallback.
- Nature has processed an estimated 100 billion tonnes of cellulose (the structural material found in plant cell walls) annually as a routine ecosystem function, while fashion has produced and discarded around 110 million tonnes of textile fibre per year, most of it sent to landfill, incineration, or informal dumping.
- In Ghana, The Or Foundation's work at the Korle Lagoon has offered a community-grounded account of what happens when the fashion industry's discards concentrate in a single place, and what the lagoon's own biological systems are already revealing about the limits of the current model.
- In the Netherlands, Circle Economy has coordinated a staged pathway routing hard-to-recycle textile waste through enzymatic hydrolysis (a process that uses enzymes to break down complex molecules), fermentation, and gasification (conversion of material into combustible gas), producing biodegradable PHA (polyhydroxyalkanoate, a bioplastic produced by microorganisms) bioplastics as a usable output.
- In Germany, the Beneficial Design Institute has developed processes that transform mixed textile waste into biocompatible (compatible with living tissue) materials, including PHB (polyhydroxybutyrate, a biodegradable polymer produced via bacterial fermentation), designed to break down in soil, water, and the human body.
- The Biomimicry Institute, Seattle, released the completed case studies from the Nature of Fashion: Design for Transformation initiative on Tuesday.
ABOUT THE INITIATIVE: The initiative has centred on a single question: what would it take for the fashion industry to handle its own waste the way nature handles decomposition. The programme has framed decomposition not as a fallback once recycling hits its limits, but as a parallel strategy from the start, proposing a shift from take-make-waste to break-down to build-up.
- The initiative has been funded by the Laudes Foundation, which supports action to address the dual crises of inequality and climate change.
- The programme has documented how most of fashion's discards end up in landfill, incineration, or informal dumping grounds far from where they are made, with no biological recovery step built into the process.
- The programme has asked whether biological decomposition, already processing an estimated 100 billion tonnes of cellulose per year across Earth's ecosystems, can serve as a design model for fashion's own material recovery.
COUNTRY BY COUNTRY: Three country pilots have produced the completed case studies, each documenting a distinct biological pathway for converting textile waste into recoverable material. The Or Foundation's work in Ghana has centred on environmental justice and ecological accountability at Kantamanto Market, one of the world's largest secondhand clothing hubs, and the Korle Lagoon, where microbial communities have been responding to the presence of synthetic textile waste, turning a site of environmental crisis into what Katia Osei has described as an unprecedented Living Lab (a real-world environment used as an open testing ground for new processes).
- In the Netherlands, Circle Economy has coordinated a hub of innovators, including BioFashionTech, EV Biotech, TNO, and ErdoTex, around a staged biological pathway routing textile waste through enzymatic hydrolysis, fermentation, and gasification.
- Microbial communities at the Korle Lagoon have been evolving to metabolise synthetic polymers once thought indestructible, pointing to biological systems already responding to the presence of synthetic textile waste.
- The Netherlands pathway has produced usable outputs including PHA bioplastics, offering a recovery route for textile waste streams that conventional recycling cannot process.
- The Beneficial Design Institute in Germany has developed processes that convert mixed textile waste into biocompatible materials, including PHB, a biodegradable polymer produced via bacterial fermentation, with breakdown pathways spanning soil, water, and the human body.
- Germany's standing as the continent's largest fashion market, with a 64% textile collection rate and approximately 250 biotechnology firms, has provided conditions the institute has identified as suited to pioneering this transformation.
WHAT THEY SAID
Decomposition is the piece missing from the circular economy conversation. In nature, decomposition is what actually closes the loop, turning one process's discards into the next process's raw material. Fashion doesn't have an equivalent step yet. These pilots are early, real attempts to build one in, not as a fallback once recycling hits its limits, but as a parallel strategy from the start.

Director of Nature of Fashion
The Biomimicry Institute
Nature has been refining decomposition for 3.8 billion years, and it treats breakdown as the beginning of the next cycle, not the end of the last one. What these three pilots show is that fashion can do the same. The technology exists, the biology exists, and our job now is to make sure the industry designs for transformation from the start.

At the heart of Accra lies Kantamanto Market, one of the world's largest hubs for secondhand clothing remanufacturing and recirculation. The market provides a critical service of giving clothing a second life within a broken fashion industry built on overproduction, planned obsolescence, and exploitative trade flows. The compounded crisis of overflowing textiles in a city with an under-resourced linear waste management system makes it clear that nature pays the ultimate price, however, the area's microbial communities are evolving to metabolize synthetic polymers once thought indestructible, turning a site of crisis into an unprecedented Living Lab.

The Nature of Fashion: Design for Transformation initiative embodies the Beneficial Design Institute's vision of positive fashion. Germany, Europe's largest fashion market with a 64% textile collection rate, provides ideal conditions for this transformation. 250 biotechnology firms, deep circular economy expertise, and established textile infrastructure position the region to uniquely pioneer Europe's future.
