Abstract: A biodegradable plastic formulation comprises about 75 wt % to about 85 wt % of a biodegradable polymer, and about 15 wt % to about 25 wt % of poultry waste biochar comprising a particle size of 50 ?m or less. A process for producing a biodegradable plastic product comprises forming biochar from poultry waste; formulating about 75 wt % to about 85 wt % of a biodegradable polymer with about 15 wt % to about 25 wt % of the biochar and extruding the formulation to produce pellets; and using the pellets in a production process to produce the biodegradable plastic product.
