4.1  The processes of dismantling, collection, transportation, storage, disassembly, comprehensive utilization, and disposal shall follow the principles ofreduction, resource utilization, and harmlessness. Priority should be given to processes and equipment withlow energy consumption, high resource recovery rates, and low pollutant emissions.

4.2  Recycling and disposal enterprises shall have storage sites that meet environmental protection requirements and implement closed and standardized management (except for enterprises using mobile equipment for disposal).

4.3  Before disposing of waste photovoltaic equipment, the type, specifications, structure, and characteristic pollutants should be considered, and corresponding disposal plans should be formulated, clarifying the disassembly process and utilization/disposal direction. Waste photovoltaic equipment and its disassembly products should not be directly landfilled, discarded, or mixed with domestic waste and construction waste.

4.4  The concentration of pollutants discharged inwastewater during the comprehensive utilization of photovoltaic laminates and their metal and non-metal materials shall comply with the provisions of national pollutant discharge standards such as GB 8978. Where local pollutant discharge standards are applicable, they shall comply with the provisions of local pollutant discharge standards.

4.5  The emission concentrations of pollutants such asvolatile organic compounds,hydrogen sulfide,lead and its compounds, andtin and its compounds in exhaust gases shall comply with the provisions of national pollutant discharge standards such as GB 37822, GB 14554, GB 31574, and GB 16297. Where local pollutant discharge standards are applicable, they shall comply with the provisions of local pollutant discharge standards.

4.6  The entire recycling and disposal process shall comply not only with national ecological environment laws and standards but also with relevant provisions of national laws and standards on production safety, occupational health, transportation, and fire prevention.

5.1  Dismantling Process shall be based on the principles ofminimizing environmental pollution and maximizing resource utilization. The dismantling site shall have complete safety and environmental protection facilities. For processes involving cutting and crushing, measures shall be taken to prevent oil leakage, dust dispersion, and noise impact. Explosive or violent methods such as blasting or whole pulling shall not be used for dismantling. The dismantling process shall include measures such as safe component removal, isolation of pollution sources, classified collection, and packaging to prevent heavy metals (e.g., lead, cadmium), oils, chemical solvents, and ash deposits from entering the soil. The surrounding ecological environment shall be promptly restored after dismantling.

5.2  Photovoltaic components, support systems, junction boxes, inverters, transformers, cables, energy storage systems, and other parts shall bedismantled by category. The dismantling process shall prevent parts from breaking and scattering. After dismantling waste photovoltaic equipment, base materials shall not be directly discarded.

5.3  Dismantled waste photovoltaic equipment shall be temporarily stored in designated areas by category. Based on product characteristics, support systems, specialized containers, or equipment shall be used for classified collection. Identification zones shall be established based on the characteristics of waste photovoltaic equipment, and dismantled products shall be stored in separate areas and promptly cleared.

5.4  Temporary storage areas shall have pollution control measures such as rainproofing, dust suppression, leakage prevention, and seepage prevention.

6.1  Dismantled waste photovoltaic equipment shall be promptly transported, and measures shall be taken during transportation to prevent dust dispersion, leakage, and seepage to avoid secondary pollution.  

8.1.5 When pyrometallurgical methods are used for treating PV laminates, the treatment equipment shall prevent the escape of pyrolysis gases at the feeding and discharging ports. Temperature sensing devices should be installed within the equipment. Dust suppression facilities shall be provided during product conveying. Flue gas collection and purification devices, along with online exhaust gas monitoring devices, shall be installed to achieve automated control throughout the entire process of exhaust gas collection, purification, and monitoring. For exhaust gases containing pollutants such as sulfur dioxide, nitrogen oxides, fluorides, non-methane hydrocarbons, particulate matter, and hydrogen sulfide, technologies such as desulfurization, denitrification, combustion, and dust removal shall be selected and combined based on the exhaust gas's composition and concentration.

8.2.3 When pyrometallurgical methods are used for recovering metals from solder ribbons, measures such as splash prevention and negative pressure collection shall be taken. Dust suppression measures shall be implemented during product conveying, and flue gas collection and purification devices shall be installed. For exhaust gases containing pollutants such as sulfur dioxide, nitrogen oxides, fluorides, lead and its compounds, and tin and its compounds, technologies such as desulfurization, denitrification, combustion, and dust removal shall be selected and combined based on the exhaust gas's composition and concentration.

8.3.3 When pyrometallurgical methods are used for recovering glass, measures such as splash prevention and negative pressure collection shall be taken. Dust suppression measures shall be implemented during product conveying, and flue gas collection and purification devices shall be installed. For exhaust gases containing pollutants such as sulfur dioxide, nitrogen oxides, fluorides, lead and its compounds, and tin and its compounds, technologies such as desulfurization, denitrification, combustion, and dust removal shall be selected and combined based on the exhaust gas's composition and concentration.

9.1.3 Records related to the recycling and treatment of waste photovoltaic equipment, including training records, management ledgers, dismantling activities, and environmental protection work reports, shall be retained for a period of not less than 3 years.

9.2.3 The treatment enterprise is recommended to have video surveillance within the plant area that covers the entire process from the entry of waste photovoltaic equipment to the exit of dismantled products. This should at a minimum include key areas and points such as the plant entrance and exit, the feeding port, monitoring points for measuring equipment, storage areas, and their entry and exit points.
