This research focuses on fabricating blends and composites from natural polymers
especially from proteins and natural epoxy, and describing the properties of plastics made
from them. Specifically, plastic samples from partially denatured feathermeal and
bloodmeal proteins, derived from the animal co-products (rendering) industry, were
successfully produced through a compression molding process. The modulus (stiffness)
of the material obtained was found to be comparable with that of commercial synthetic
materials, such as polystyrene, but was found to have lower toughness characteristics,
which is a common phenomenon among plastics produced from animal and plant
proteins. Therefore, this study explored blending methods for improving the toughness.
