Abstract：Biodegradable plastics have been widely applied in many fields in recent years. Waste biodegradable plastics (WBP) products may easily cause environmental pollution, thus the disposal and resource utilization of WBP are important guarantees for large-scale application of this type of plastics. This paper summarized the main disposal approaches of WBP, especially focused on mechanical recycling, chemical recycling, biological treatment, landfill, incineration and upgrade utilization. Furthermore, the problems encountered in the treatment process of WBP were systematically analyzed, and the future development trend of WBP recycling was predicted. The main purpose is, to provide guidance for the green and efficient treatment of WBP.
