BUSINESS
Engineers enzymes using generative AI and high-throughput screening for enzymatic recycling of plastics such as PET into recycled resins. Develops engineered enzymes for enzymatic plastic recycling, breaking down PET and polyurethane into monomers for repolymerization into virgin-quality resin. Uses generative AI and high-throughput screening for enzyme design. Licensed NREL enzymatic PET deconstruction technology (June 2025).
