Abstract
The invention is directed to a method for preparing a polymer derived from an animal protein, such as in a feedstock derived from animal by-products. The method involves hydrolyzing proteins present in a feedstock to obtain hydrolyzed proteins, wherein hydrolysis is conducted under conditions sufficient to digest the proteins and destroy pathogens; extracting a protein fraction from the hydrolyzed proteins; and treating the protein fraction with a crosslinking reagent to form the polymer. The crosslinking reagents may include epoxies. The polymer may be further processed to form a thermoset plastic. The polymer may be used as an adhesive, or in the preparation of a natural fiber composite material.
