The study aims to produce biodegradable plastic using cassava starch as its main component. Cassava starch was mixed with water, epoxydized soya bean oil (ESBO), glycerol, and polyvinyl alcohol (PVA). The mixture was then compressed and tested. Three preparations were made from the mixture. The first preparation contained 50 grams starch, 50 grams water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams glycerol. The second preparation contained 65 grams starch, 65 grams water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams gycerol. The third preparation contained 80 grams starch, 80 grams water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams gycerol. The first preparation exhibited the most desirable mechanical properties. The material produced was proven to be biodegradable. READ MORE….
