Enzymes: The Core of Our Technology

The Science Behind Enzymatic Recycling

Our technology is built on a foundation of advanced enzyme engineering. We identify enzymes that break down plastic, then engineer them to function as high-performance “molecular scissors” using artificial intelligence and next generation enzyme screening technologies. These enzymes are used as part of a sustainable plastic recycling process that recovers chemical monomers and reuses them as part of an infinite plastic recycling process that will eliminate our need to manufacture plastics from fossil fuels. 

Advantages

Why Enzymes?

High Quality
Resin

100% recycled PET resin with the same performance properties as virgin resin produced from fossil fuels. Enables infinite plastic recycling.

Improved Process Economics

Cost of enzymatically recycled PET resin is equivalent to virgin PET. Premium quality, circular resin enables premium pricing.

GHG Emissions

Emissions reduced by >70% using low temperature enzyme technology and green chemistry.

Small Footprint Plants

Low emission, economical small scale commercial plants with lower permitting requirements.

HOW IT WORKS

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
