Degradable polymer plastics have been widely used in various fields. However, second-hand plastic waste causes environmental and social harm. Some developed countries have successively formulated regulations that restrict or prohibit the use of non-degradable plastics in certain circumstances, and require the use of biodegradable plastics. Therefore, the government and the plastics industry attach great importance to the research and development of biodegradable plastics around the world, and at the same time, effective measures for the treatment and recycling of waste plastics have been formulated. With the coordination and support of various governments, biodegradable plastics have become a hot topic in the international plastics industry.
