摘要

The increasing environmental concerns associated with synthetic plastics have accelerated the demand for biodegradable alternatives, particularly for commercial and industrial applications. This study aimed to develop bioplastic films using starch extracted from banana peels and cellulose microfibrils derived from sugarcane bagasse (SCB), two abundant agro-waste sources. Cellulose isolation involved sequential delignification, sulfuric acid hydrolysis, hydrogen peroxide bleaching, and alkali treatment. Further FTIR analysis of extracted starch and cellulose also confirmed the absorption patterns typical of starch and cellulose. Bioplastic films were formulated with varying starch-to-cellulose ratios and evaluated for their mechanical, physicochemical, and degradation properties. Results demonstrated that increasing cellulose content enhanced both tensile strength and elongation, with the optimal formulation (50:50 starch: cellulose) exhibiting a tensile strength of 3.1 N/mm² and an elongation of 3.86%. Water uptake was significantly reduced in cellulose-containing films, indicating improved water resistance. The bioplastics also displayed strong resistance to salt, 1% sulfuric acid, and 1% alkali, while higher concentrations of acid and alkali led to moderate degradation. Biodegradability was confirmed through weight loss measurements and SEM analysis, with the 50:50 formulation achieving a 44.75% weight loss within 15 days of soil burial. These findings confirm that agro-waste-derived starch and cellulose are promising materials for the production of sustainable bioplastics with potential applications in food packaging, medical materials, and related industries.
