Venture backed ANU spinout Samsara is part of a global movement to discover new enzymes that are able to digest plastic and turn it into useful chemical building blocks.

Plastic-munching enzymes are computationally designed by ANU chemistry researchers, and their processes are being scaled up. Samsara plans to open a plant in 2022 that can reprocess things like PET bottles and old footy jumpers into monomers, which can then be remade into plastics that are as good as new.

"we’re actually depolymerising plastic in just under an hour, which is a fantastic improvement in performance," according to co-founder Paul Riley.
