ABSTRACT:
Provided is a method for accelerating the biodegradation of aliphatic-aromatic co-polyesters comprising greater than 60 mol percent aromatic acid, based on total diacid in the co-polyester. The method involves contacting at least one hydrolytic enzyme in aqueous solution to the co-polyester.
