Thermosetting Proteinaceous Plastics from Hydrolyzed Specified Risk Material



In response to the bovine spongiform encephalopathy (BSE) outbreak in the last decade, the US, Canada and several other countries implemented an enhanced feed ban that eliminates specified risk material (SRM) from all animal feed, pet foods and fertilizer applications. The environmental risks and severe loss of profitability by the rendering industry associated with landfilling of several million tons of SRM demand immediate and economically viable solutions of converting such materials into value added applications. In this research, SRM was hydrolyzed, the protein hydrolyzates were extracted and further modified through chemical crosslinking to develop a novel protein-based plastics. The plastics developed in this research exhibited promising thermal and solvent resistance, and tensile strength.mame201200429-gra-0001
