Plastic wastes have been accumulated in the environment, and these plastics finally fragmented into smaller debris. There are three common standards used to classify micro-plastics, which are diameters, origins (primary or secondary), and monomers. In addition, various techniques and methods are applied to examine the changes before and after biodegradation. This paper also introduces several methods used to improve the efficiency of biodegradation. In the end, there is a summary about some progresses of biodegradation of plastics/micro-plastics.
