Abstract: A biodegradable bioplastic composition of from 80 wt % to 95 wt % of a polymer having one or more thermoplastic polyester polyhydroxyalkanoates (PHA) and from 5 wt % to 20 wt % an organic dispersed within the polymer. The biodegradable bioplastic composition is devoid of petrochemically derived components, fossil fuel derived components, processing aids, and plasticizer additives. A process is also disclosed for preparing the biodegradable bioplastic composition. The process involves compounding one or more thermoplastic polyester polyhydroxyalkanoates (PHA) and an organic to form a mixture and homogenizing the mixture. Homogenizing includes feeding the mixture to a first extruder and extruding the mixture to form a composite composition and feeding the composite composition to a second extruder and extruding the composite composition to form the biodegradable bioplastic composition.
