“Over eight years they re-engineered LCC – now LCCICCG – to become a trained PET specialist.

The enzyme is now so efficient that it can completely break the PET polymer down to its constituent monomers—the chemicals producers need to make new plastic.

Prof Marty likens it to breaking apart a pearl necklace.

‘We are using an enzyme that you can consider a molecular scissors,’ he says. ‘We break down the link between the pearls, liberate the pearls and in this way, after purification, we can sell these pearls again.'”
