This podcast episode explores chemical recycling as a potential solution to the problem of plastic waste. Chemical recycling uses enzymes to break down plastic into its basic building blocks, which can then be used to make new plastic. One of the key challenges in chemical recycling is finding enzymes that can break down stronger plastics like PET. However, a recent discovery by researcher Sintui Suleyman has identified a new enzyme that can break down PET, which could lead to a major breakthrough in the field of chemical recycling.
