Technical Questions About Enzymatic PET Recycling

We use engineered enzymes to selectively break PET into RPTA and REG. After purification, these monomers can be repolymerized into RB®PET and other recycled polyester materials.

We evaluate post-industrial textile scraps, post-consumer polyester textiles, colored PET, PET blends, and selected industrial or packaging waste. Every project begins with a feedstock assessment.

Mechanical recycling remelts PET, while our process depolymerizes it into RPTA and REG for purification and repolymerization. Engineered enzymes selectively target PET under mild, aqueous conditions, supporting complex textile waste that may be difficult to process mechanically.

Our enzymatic process operates at around 60°C and atmospheric pressure, with PET depolymerization completed within eight hours under defined conditions. We also operate a 300 t/y enzymatic RPTA production line, validating the process beyond laboratory and pilot testing.

We can provide available samples, technical data, certification documents, and selected third-party reports. We will help you find the right information.
