Petroleum-based plastics have led to serious environmental pollution gaining great attention in developing low-cost, renewable, and degradable starch-based bioplastics. This study mainly aims to blend starches from cassava peel (CPS) and mung bean peel (MPS) for the production and characterization of bioplastics. Biodegradable plastics were produced using cassava and mung bean peels in varying ratios of 10:0, 7:3, 6:4, 5:5, 4:6, 3:7, and 0:10, with glycerol and sorbitol as plasticizers. The produced bioplastics were characterized through mechanical and chemical property tests. Data were analyzed statistically using one-way ANOVA and Tukey-HSD tests to confirm the significance of the observed differences. The mechanical property results showed an improvement in tensile strength with increasing mung bean starch content, reaching up to 6320 Pa. After 17 h of observation, biodegradation results indicated that the bioplastic composed of pure MPS degraded the fastest, achieving complete degradation. Furthermore, bioplastics made from pure CPS and MPS were slower to dissolve, taking 15.2 days and 13.2 days, respectively. Overall, the blending of starch originating from cassava and mung bean peels was found to be a promising approach for the production biodegradable plastic.
