Researchers used advanced neural‑network‑driven protein design tools to create a new enzyme capable of breaking down polyurethane, a widely used polymer in foam cushioning and other products. The enzyme works within an industrial‑style recycling process, converting the polymer back into its basic building blocks for reuse. This breakthrough addresses the complex chemistry of polyurethane, which has resisted previous recycling efforts, and offers a potential pathway to reduce plastic waste and avoid hazardous incineration.
