Abstract

Plastic waste is one of the biggest threats to our ecosystem, and its continued use may endanger the existence of human life on Earth if no viable alternative is found. Using paper as a substitute is not a suitable solution due to its limited applications compared to plastic. This situation urges the search for biodegradable alternatives derived from sustainable materials. This study aims to develop biodegradable plastic from banana peels, providing a sustainable and eco-friendly alternative to conventional plastic, while contributing to the circular economy and sustainable innovation. Waste banana peels were collected, cleaned, and dried. The peels were then blended into a paste and combined with natural additives such as gelatin (binding agent), glycerin (binding agent), and vinegar (pH adjustment). The mixture was processed under controlled heat to form biodegradable plastic. The resulting material was evaluated for strength, water resistance, and decomposition under controlled conditions. The produced biodegradable plastic showed signs of decomposition due to microbial activity, occurring significantly faster than in conventional plastics. This indicates the material’s biodegradability and potential to improve soil quality as biomass. The approach represents a low-cost, eco-friendly solution that also adds value to organic waste, highlighting its potential role in sustainable material innovation.
