Upcycled textile waste into 100% polyester resin at the lowest cost.

The Tough Tech problem we are solving

Less than 1% of clothing and textile waste is recycled each year globally. Mechanical recycling only works on pristine fabrics without stains, dyes, buttons, or impurities, while conventional chemical recycling remains highly energy-intensive, cost-prohibitive, and burdened by a steep green premium. As a result, millions of tons of garments end up in landfills, incinerators, or waterways, compounding emissions and environmental contamination.

About our solution

MacroCycle's patented SolvoGenesis™ process breaks down polyester textile waste, regardless of color, blend, or contamination, and rebuilds it into virgin-quality material, a true drop-in replacement for new polyester. The process uses significantly less energy than conventional recycling methods, can run on renewable energy, and enables brands to close the loop on textile waste without sacrificing quality or price.
