Abstract Biodegradabilities of polymers and their composites in a controlled compost were described. Effects of sizes and shapes of samples on biodegradability were studied. Introduction Polymers are widely used in various industrial fields due to their merits, such as light weight, resistance to chemicals, resistance to the environment, easy processing, etc. It is difficult for polymers to be treated after use due to their resistance to the environment. When polymers are disposed of in a natural environment, they remain for a long time without degradation. One of the solutions to this problem of polymers after use is the development of biodegradable polymers.
