ABSTRACT Bioplastics are destructive plastics which break down by the environment, humidity and microorganism activity. These bioplastics can be used just like conventional plaques. Bioplastics include natural polymers made from plant and animal materials. Tapioca flour is pure starch obtained from the extraction of cassava milling and continues to amylose and amylopectin. Maize flour is f…
