Plastic pollution is everywhere, and a good amount of it is composed of polyethylene terephthalate (PET). This polymer is used to make bottles, containers and even clothing. Now, researchers report in Environmental Science & Technology that they have discovered an enzyme that breaks apart PET in a rather unusual place: microbes living in sewage sludge. The enzyme could be used by wastewater treatment plants to break apart microplastic particles and upcycle plastic waste.
