For example, methanolysis can be used to recycle PET products like fibers and sheets that aren’t amenable to mechanical methods. And firms have been breaking down nylon using hydrolysis for many years. But the bulk of the plastics we use—the candy wrappers, stand-up pouches, potato chip bags, protective packaging, single-use cups, frozen food bags, razors, toothpaste tubes, cotton swabs, and other objects of our daily lives—defy both mechanical recycling and depolymerization.
