Scientists from the University of Portsmouth have created a new super enzyme that breaks down plastic bottles. The process is 6 times faster than before.
So far, PET plastic (recycling polyethylene terephthalate), used for the production of single-use drink bottles, carpets, and clothing, has been broken down by the PETase enzyme, engineered by the same team. Now the researchers have added another enzyme, MHETase, to the process and managed to significantly speed it up. Both enzymes were found in a plastic-eating bug discovered in 2016 at a Japanese waste site.
