This study endeavors to fabricate bioplastic specimens utilizing plantain and yam peels, incorporating diverse proportions of plasticizers. Glycerol and sorbitol were employed individually as plasticizers to enhance the malleability of the material. A comprehensive analysis of the distinct physical and chemical attributes (including moisture content, water absorption, soil biodegradation, and tensile strength) resulting from diverse compositions was conducted by generating five samples for each type of bioplastic. These specimens were formulated utilizing varied quantities and combinations of plasticizers. The distinctive characteristics of the bioplastic samples render them highly adaptable for a broad spectrum of applications. All ten specimens were engineered utilizing natural and ecologically benign raw materials, manifesting biodegradability and thereby affirming their potential as an environmentally sustainable substitute for traditional plastics.
