In 2023, Protein Evolution became the first U.S. company to successfully use its Biopure™ biological recycling technology to produce a new item of clothing made entirely out of fibers derived from polyester waste.
Stella McCartney is collaborating with Protein Evolution to trailblaze the future of sustainable fashion, exploring how these 100% recycled fibers could be used to produce new clothing, footwear, and other infinitely recyclable products.
With Biopure™, polyester manufacturers can swap petroleum-derived polyester precursors with waste-derived polyester precursors — creating completely circular polyester without sacrificing quality.
