100% Biodegradable Starch-based plastics 

Thermoplastic starch currently represents the most widely used bioplastic, constituting about 50 percent of the bioplastics market[citation needed]. Simple starch bioplastic film can be made at home by gelatinizing starch and solution casting. Pure starch is able to absorb humidity, and is thus a suitable material for the production of drug capsules by the pharmaceutical sector. However, pure starch-based bioplastic is brittle. Plasticizer such as glycerol, glycol, and sorbitol and can also be added so that the starch can also be processed thermo-plastically.
