Birch Biosciences, a startup focused on AI-powered enzymatic plastic recycling, today announced a global patent license agreement with the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) to commercialize a novel enzymatic deconstruction processing technology that breaks down polyethylene terephthalate (PET)—a common plastic used in packaging and textiles—to recover valuable chemical building blocks.
The licensed technology, developed by NREL researchers, enables the rapid and efficient recovery of high-value PET monomers from enzymatic breakdown of PET. These monomers are then remanufactured into virgin-quality PET that can be used to create 100% recycled content products.
By securing licensing rights to this innovation, Birch Biosciences will integrate the NREL-developed downstream chemical processes into its proprietary biocatalytic recycling platform. The goal is to accelerate the commercialization of sustainable, closed-loop solutions for plastic waste, helping address a global environmental challenge.
