As time is going on the rate of use of plastic is increasing and there is a big challenge before us to degrade that plastic. The plastic is durable and take much time to complete degradation. It takes about 1000 years to complete degradation in natural environmental condition. The plastic could sometimes responsible for the cause of block in digestive system of aves and mammals and also affects the seed germination in plants. When we go through the literature, there are many plastic degrading technologies are developed, but the economic and eco-friendly method could be biodegradation using indigenous microbes. The objective of this study was to isolate the plastic degrading bacteria from the Pirana municipal solid waste dumping site, Ahmedabad and use that bacteria in degradation of UV treated plastic in developed aerobic composting bioreactor. The results from the study shows the confirmation of biodegradation of plastic sample which is analysed by surface change, comparing weight loss before and after the biodegradation experiment. Finally, it could be concluded that if we disturb the physical state (i.e.by reducing molecular weight), the biodegradation rate of the plastic could be increased.
