A study with results published recently in the journal Proceedings of the National Academy of Sciences (PNAS) showed how an international team of collaborators managed to boost PETase's capacity to break down plastic.

"In our research project, we characterized the three-dimensional structure of the enzyme that can digest this plastic, engineered it to boost its degradation capacity, and demonstrated that it also acts on polyethylene-2,5-furandicarboxylate (PEF), a PET substitute made from renewable raw materials," said co-author Rodrigo Leandro Silveira, a postdoctoral fellow at the University of Campinas's Chemistry Institute (IQ-UNICAMP).
