Abstract

Plastic is known for its uses and purposes; however, it is also the main problem due to its decomposition period that lasts a hundred years. This causes an alarming problem in the country due to its high rate of plastic pollution. Thus, this research aims to produce a bioplastic that will serve as an alternative instrument to lessen the issue concerning plastic pollution. Bioplastics are a promising alternative to traditional plastics, which are made from non-renewable resources and are not biodegradable. Starch from banana peels combined with potato starch is utilized in making the bioplastic. The material produced was divided into three different ratios and tested with two different properties: (A) tensile strength & (B) elongation rate. Results showed that upon the computation of the tensile strength, Treatment C (50% banana peel starch - 50% potato starch) showed a promising result making it the optimal ratio for tensile strength. Treatment B (25% potato starch - 75% banana peels starch) stood out among the rest in elongation rate. This results in the fact that bioplastics may still be employed; however, each ratio of the bioplastic may represent a different type of plastic according to their purpose and needed quality. Overall, the use of banana peels and potato starch has potential in making bioplastic.
