Abstract
A method of depolymerizing a polymer by combining together the polymer with an enzyme (a hydrolytic enzyme capable of catalyzing cleavage of said (CO)—O bond of an ester or carbonate linkage of the polymer) and an aqueous liquid to provide a reaction mixture. The polymer comprises a (CO)—O bond of an ester or carbonate linkage. The reaction mixture defines a ratio eta (η) of liquid volume, in μL, to total solids, in mg, that is less than 2 μL/mg. Then, allowing an enzyme-catalyzed reaction of the enzyme with the polymer to take place thereby forming a reaction product.
