Several hundred million tons of plastics produced worldwide accumulate in nature. The thermoplastic resin polyethylene terephthalate (PET) is highly recalcitrant to degradation. A recent report from Tournier and colleagues provides unprecedented advances towards a circular PET economy by describing an engineered microbial enzyme that efficiently depolymerizes PET.
