ABSTRACTPetroleum based plastic remain in the nature for decades.In the 21st century, naturally biodegradable products have increased great importance. In the present study the characteristics of starch based bioplastic are briefly introduced and degradability of material studied. Renewable source such as Starch extracted from potatoes was used as primary source for synthesizing starch-based bioplastic. Physical characterisation of the synthesised bioplastic was done which included measurement of thickness, tensile strength, Scanning Electron Microscopy and U.V Mass-Spectrophotometry. The bioplastic samples were subjected to environmental degradation in soil obtained from garbage dumping site and the degradation was monitored at regular intervals of time. The starch-degrading microbes were isolated from soil and further identified using conventional biochemical tests and confirmed with 16S rRNA sequencing. The synthesized starch-based bioplastic hence proved to be eco-friendly and a good alternative to conventional petroleum-based plastic.
