• YARN-TO-YARN® by Rheiazymes: Enzymes for a future without Fashion Waste

Recycling is dead. Long live recycling!

Fashion consumes 100 million tons of non-renewable resources per year.

Fast Fashion blasts 1.2 billion tons of CO² into the environment per year. 

And only 1% of clothes ever become new clothes again. 

Why all this waste? Why aren’t we recycling? 

Because we couldn't. Not the mixed synthetic fibers. Until now...

Rethinking fashion. With circular fabrics.

Game Changer Technology for YARN-TO-YARN® Recycling

YARN-TO-YARN® is our commitment to closing the recycling gap for synthetic yarn blends and functional textiles through our Molecular Bio-Recycling technology. Using natural enzymes, we recover raw materials on a molecular level - in a purely biological process inspired by nature.

Our flagship project is developing the technology for polyamide-elastane (PA/EA) blends and establishing a circular YARN-TO-YARN® ecosystem. 

To bring this game changing technology to market, we partner with forward-thinking textile companies and the Migros Pioneer Fund who share our passion for sustainability and innovation and who are unafraid to challenge the status quo. Together, we are creating a new industry standard - one that values the environment and the future of our planet as much as financial results.

Made possible by...
