Abstract: Adove, May Gwendolyn O., Afionuevo, Chrizel Caite H., Maglabe, Richelle N., Perdon, Mary-Ann N. Applied Research II (General Science Curriculum) Cavite State University, Indang, Cavite, March 2002 “Manufacture of Biodegradable Plastics from Taro (Colocasia esculenta)” Advisers: Mrs. Ma. Corazon V. Herrera and Prof. Dulce L. Ramos The study aims to produce biodegradable plastic using taro starch as its main component. Taro starch was mixed with water, epoxydized soya bean oil (ESBO), glycerol, and polyvinyl alcohol (PVA). The mixture was passed through a rollmill and then compressed. Three preparations were made for the mixture. The first preparation or Treatment contained 50 grams of starch, 50 grams of water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams glycerol. The second preparation or Treatment II contained 75 grams of starch, 50 grams of water, 50 grams of PVA, 2.5 grams ESBO, and 2.5 grams glycerol. And the third preparation for Treatment III contained 100 grams of starch, 75 grams water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams glycerol. Treatment III exhibited the most desirable mechanical properties in terms of strong acid test, strong base test, flammability test, water test, and biodegradability test. In the strong acid test, Treatment III decreased its length by 9.84% and its width by 29.53%. In the organic solvent test, Treatment III has expanded its length by 1.18% and its width by 1.18% also. Treatment III got the shortest burning time of 33 minutes. In water test, Treatment II] has reduced its length by 53.94% and its width by 60.63%. In the biodegradability test, Treatment II also reduced its length by 54.72% and its width 63.78%.

The study aims to produce biodegradable plastic using taro starch as its main component.

Taro starch was mixed with water, epoxydized soya bean oil (ESBO), glycerol, and polyvinyl alcohol (PVA). The mixture was passed through a rollmill and then compressed.

Three preparations were made for the mixture. The first preparation or Treatment contained 50 grams of starch, 50 grams of water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams glycerol. The second preparation or Treatment II contained 75 grams of starch, 50 grams of water, 50 grams of PVA, 2.5 grams ESBO, and 2.5 grams glycerol. And the third preparation for Treatment III contained 100 grams of starch, 75 grams water, 50 grams PVA, 2.5 grams ESBO, and 2.5 grams glycerol.

Treatment III exhibited the most desirable mechanical properties in terms of strong acid test, strong base test, flammability test, water test, and biodegradability test. In the strong acid test, Treatment III decreased its length by 9.84% and its width by 29.53%.

In the organic solvent test, Treatment III has expanded its length by 1.18% and its width by 1.18% also. Treatment III got the shortest burning time of 33 minutes. In water test,

Treatment II] has reduced its length by 53.94% and its width by 60.63%. In the biodegradability test, Treatment II also reduced its length by 54.72% and its width 63.78%.
