| This research work describes the properties of plastics made from partially denatured proteins produced by the animal co-product (rendering) industry, and describes those plastics' fabrication. Specifically, plastic samples from partially denatured feathermeal protein were successfully produced by a compression molding process. The modulus (stiffness) of the material obtained was found to be comparable with that of commercial synthetic materials but was found to have lower toughness characteristics, which is a common phenomenon among plastics produced from animal and plant proteins. A reversible stress-strain property was observed over the yield region. Plastic forming conditions for undenatured animal proteins such as albumen and whey proteins were also formulated for fabricating plastics out of these proteins' blends with feathermeal proteins. The resultant plastic samples that were developed out of these biomacromolecular blends demonstrated improved mechanical properties as compared to neat plastics from feathermeal proteins. The values for the stiffness of the feathermeal/whey blends deviated from simple mixing rule and showed a synergistic effect. |
