9% Of Plastic Is Recycled.
We’re Fixing That.
The 9% US plastic recycling rate hasn’t improved in 15 years. Most recycled plastic is lower quality and higher cost than virgin plastic manufactured from fossil fuels. Today, manufacturing new plastic is responsible for 7% of global carbon emissions.
The Science Behind
Enzymatic Recycling

We use generative AI and proprietary high-throughput screening techniques to redesign enzymes with transformational recycling properties. These high-performance enzymes are integrated into a proprietary recycling process that breaks down plastic polymers, enabling the production of 100% recycled content plastics. This eliminates the need for fossil fuels in plastic manufacturing.

Our Enzymatic Recycling Process
Bottles, clamshells, and polyester
textiles are shredded to small
particle sizes
Enzymes break down plastic
polymers into chemical monomers
by breaking chemical bonds
100% recycled plastic
resin is used to
manufacture high quality
plastic products
Chemical monomers are
repolymerized into 100% recycled
plastic resin
Bottles, clamshells, and polyester textiles are shredded to small particle sizes
Enzymes break down plastic polymers into monomer “building block” chemicals by breaking chemical bonds
Monomers are repolymerized into 100% recycled plastic resin
100% plastic resin is used to manufacture high quality plastic products
