Formulation and Evaluation of Herbal Bio Plastic from Banana Peels

Abstract

The increasing environmental impact of synthetic plastics has accelerated the search for sustainable and biodegradable alternatives. Herbal bioplastics derived from natural waste materials have emerged as a promising solution, with banana peels being an abundant and lowcost resource. Banana peels are rich in natural polymers such as starch, cellulose, hemicellulose, and pectin, which are essential components for bioplastic production. The use of such agro-waste not only reduces environmental pollution but also promotes resource efficiency and circular economy practices. The production process of herbal bioplastic from banana peels involves several key steps. Initially, fresh banana peels are collected, thoroughly washed, and dried to remove impurities and moisture. The dried peels are then ground into a fine powder, which serves as the primary raw material. This powder is mixed with a plasticizer, typically glycerol, to improve flexibility and reduce brittleness. An acidic component such as vinegar or citric acid is also added to enhance the gelatinization and binding properties of the mixture. In some cases, herbal extracts like aloe vera or neem may be incorporated to provide antimicrobial and antioxidant characteristics, making the bioplastic more functional and suitable for specific applications. During this stage, starch gelatinization occurs, resulting in a homogeneous viscous paste. This paste is then cast onto molds or flat surfaces and allowed to dry under ambient conditions or in an oven. Upon drying, thin, flexible bioplastic films are formed. The final product is biodegradable, eco-friendly, and capable of decomposing naturally without releasing harmful substances into the environment.
