Abstract:

The development of plastic industry has made great contributions to the improvement of people’s living quality and convenience. However, the environmental pollution caused by improper waste disposal can not be ignored. The critical way to prevent and control the plastic pollution is to use, recycle and reuse plastics properly, which can prevent plastic wastes from leaking into the nature. In this sense, the construction of a high?value plastics recycling system has become the top priority. Traceability becomes the key power to achieve this goal, and the relevant policies and participation become the twin engines to promote the realization of the goal. This paper clarifies the conception of traceability and main traceable approaches, analyzes the domestic and international application scenarios, and points out the difficulties in tracing plastics in China. Based on the above results, some suggestions on the construction of traceability system in China were proposed together with the analysis for the specific elements, promoting its implementation in accordance with the corresponding policies.

Key words: plastic, high?value, recycling, tracing system
