20 Claims

1. A method for making bioplastics comprising:

culturing a biomass comprising one or more genus of microalgae, wherein at least one of the genera is a triacylglycerol-accumulating microalgae;

centrifuging the microalgae during a stationary phase of culturing to induce polymer compound accumulation;

extracting a non-triacylglycerol accumulated polymer compound from a precipitate formed during centrifugation;

incubating and dehydrating the precipitate;

grinding the precipitate to form a powder and mixing with water to form a mixture; and

adding at least one additive to form the bioplastic, wherein the additive is selected from the group consisting of: an oxidizer; a plasticizer; and a combination thereof.
