Birch Biosciences develops biotechnologies that transform plastic waste into high-quality recycled materials. The company leverages generative AI and enzyme engineering to create efficient recycling processes, addressing persistent challenges in plastic waste management.
Plastic recycling rates in the United States remain low, with only about 9% of plastic effectively recycled. This stagnation has persisted for over a decade. Most current recycling methods produce lower-quality materials that cost more than virgin plastic derived from fossil fuels. Plastic production contributes significantly to global carbon emissions, highlighting the need for innovative approaches based on available information.
Birch Biosciences engineers enzymes functioning as molecular scissors to break down plastic polymers into basic chemical monomers. These enzymes enable a proprietary recycling process that starts with shredding items like bottles, clamshells, and polyester textiles into small particles. The enzymes then depolymerize the plastics by severing chemical bonds, yielding pure monomers. These monomers are repolymerized into 100% recycled plastic resin suitable for manufacturing high-quality products. This method aims to match the quality of fossil fuel-based plastics while improving process economics.
