As the development of Chinese economy, the demand for plastic products increases rapidly. However, the defect of waste treatment technology has caused a large amount of plastic to be leaked into the environment, resulting in serious White Pollution. Biodegradable plastics have attracted the attention of the scientists and industry due to their performances: environmental friendliness, easy recycling and easy processing. Biodegradable plastics have been widely used in disposable products, agriculture, forestry, fishery, animal husbandry, and the automobile industry. Therefore, this article reviews the mainstream biodegradable plastics popular in market: polylactic acid (PLA), polyhydroxyalkanoate (PHA), polybutylene terephthalate adipate (PBAT), and polypropylene carbonate (PPC), as well as status quo of industrial development life cycle analysis (LCA), and its application in the several fields. Meanwhile, this article summarizes the relevant prohibition and restriction policies of various countries for single-used plastics products, and finally, analyzes the prospect and provides guidance for the development Chinese biodegradable plastics industry.
