Biochemical recycling of polyesters Most polyesters are very durable and non-biodegradable and only strong acids and bases and strong aromatic solvents can swell and dissolve them. Controlled degradation is almost impossible, and degradation takes a long time. Chemical recycling of polyesters can be accomplished by alcoholic or acidolysis to the monomers, but this has proven
