Production of bioplastic and its characterization using banana peel
2015
Naeem, H.
At present the chemical industry is searching for substitute to decrease usage of petroleum-based non-degradable conventional plastics. In spite of their many uses and attractive properties, petroleum based conventional plastics have also many disadvantages such as production problems, landfill disposal, incineration, plastic recycling, and their adverse effect on biodiversity. Bioplastic are plastics derived from renewable biomass sources, composed of cellulose, starches, biopolymers, and a variety of other materials. In this research a starch based substrate banana peel was used and subjected to alkali and acid hydrolysis to convert it into bioplastic film. Synthesis of bioplastic was carried out in two phases. In first stage the process parameters pH and hydrolysis time was changed over a range of values. In this stage the pH of neutral range gave the best results for tensile strength analysis 0.552N/mm2 with optimum residence time (10 minutes). In the second stage, commonly available plasticizer like glycerin, sorbitol and urea was added and compared. The sorbitol, gave maximum tensile strength (34.310 N/mm2) with 41.434 N loads in this comparison. EDS analysis shows that CK was the 'highest element (6.730/0) with 5.32 App conc and 0.7918 intensity concentration present in the biopolymer film.
