8.1.1 The appropriate utilization and disposal process shall be selected according to the material characteristics, degree of mixing, cleanliness, local environment and industry conditions of plastic waste.

8.1.2 Under the premise of complying with the Catalogue for Guiding Industry Restructuring, it shall comprehensively consider the following factors such as the generation of waste plastics in the region, the level of social and economic development, industrial layout and planning, market demand for recycled products, and the level of pollution prevention and control of recycling technologies; then reasonably determine the production scale and technical route of recycling facilities.

8.1.3 According to the types and concentrations of pollutants in the wastewater generated

during the plastic waste recycling process, corresponding wastewater collection and treatment facilities shall be equipped. The treated wastewater should be recycled; and the discharged wastewater shall implement relevant national and local discharge standards according to the functional requirements or pipe requirements of the effluent receiving water body. And the key pollutant indicators for control include chemical oxygen demand, suspended solids, pH value, chromaticity, petroleum, adsorbable organic halides, etc.

8.1.4 The monitoring, evaluation and treatment of new pollutants and priority chemicals shall be strengthened.

8.1.5 The waste gas generated during the recycling process of plastic waste shall be collected and treated. The emission of air pollutants shall comply with the provisions of GB 31572 or
