The adverse environmental degradation created by various plastics produced from petroleum products is a major concern for the world nations. The developed and developing nations have adopted various strategies on the production and usage of highly hazardous conventional plastics. Various research works have been undertaken to formulate a sustainable alternative for the conventional plastics. In this regard, an effort was made to synthesis a biodegradable polymer for large scale commercial usage in packaging applications. Biodegradable polymers can be produced from various resources. The study involves the production of bio-plastic from Banana peel and Prosopis juliflora. Cellulose, a major component required for biopolymer synthesis was extracted from Prosopis juliflora which then combined and processed with dried banana peel. Additives and preservatives that contributes to the polymer characteristics were added in suitable proportions and processed under defined conditions. The mixture was then dried at a temperature of 130℃ to yield the final product. The biopolymers thus produced were tested for its water absorption capacity, thermal resistance, tensile strength, biodegradability and microbial attacks. It was observed that water absorption capacity of the biopolymer was lower for lesser starch and higher cellulose concentrations. The tensile strength was found to be 0.67 N/mm² which was due to the addition of zinc oxide. No microbial attack was observed during storage and it was also found that the biopolymer was able to withstand high temperature up to 130℃ during its usage [ABSTRACT FROM AUTHOR]
