Waste battery classification, recycling and treatment methods

1) Environmental management for waste primary batteries The 'Technical Policy for Waste Battery Pollution Prevention and Control' stipulates that the recycling of waste primary batteries should be carried out cautiously by the responsible unit of recycling. At present, in the absence of technical and economic conditions for effective recycling, the centralized collection of waste primary batteries that have reached the national requirements for low or no mercury is discouraged. At present, the primary batteries (dry batteries) sold on the market have reached the national low or mercury-free requirements, and they are allowed to be disposed of with household garbage after being discarded. In recent years, our ministry has conducted research on the pollution characteristics of waste batteries through environmental protection public welfare projects. The research results show that: waste primary batteries are disposed of with domestic waste, which may cause additional difficulty in disposal or additional environmental risks (such as zinc caused by incineration). To the enrichment of fly ash, the difficulty of fly ash disposal is added). Therefore, we believe that the collection and recycling of waste primary batteries have a certain positive significance for environmental protection. We are cooperating with the Development and Reform Commission, Ministry of Commerce, Ministry of Industry and Information Technology and other departments to study and formulate waste primary batteries recycling policies, and promote the recycling of waste primary batteries in a timely manner. . At the same time, our ministry is organizing the revision of the 'Waste Battery Pollution Prevention and Control Technology Policy(2) Environmental management of waste batteries The 'Technical Policy for Waste Battery Pollution Prevention and Control' stipulates: The collection of waste batteries focuses on cadmium-nickel batteries, nickel-hydrogen batteries, lithium-ion batteries, lead-acid batteries and other waste rechargeable batteries, silver oxide, etc. Disused button-type primary batteries (higher mercury content). Regarding lead-acid batteries, in 2013, with the approval of the State Council, the Ministry of Industry and Information Technology, together with our Ministry, the Ministry of Commerce, the National Development and Reform Commission, and the Ministry of Finance, issued the 'Opinions on Promoting the Standardized Development of Lead-Acid Battery and Recycled Lead Industry' (Hereinafter referred to as 'Opinions'). Regarding the recycling and utilization of waste lead-acid batteries, the 'Opinions' clearly requires the establishment of a standardized and orderly recycling system to achieve standardized production, orderly recycling, and reasonable recycling of lead-acid batteries; by 2015, the recycling and comprehensive utilization of waste lead-acid batteries The utilization rate reaches more than 90%, and the proportion of lead recycling exceeds 50%, which promotes the formation of a national lead resource recycling system. At the same time, the state will further regulate the recycling of waste lead-acid batteries by individual vendors, encourage production companies to organize the recycling of waste lead-acid batteries through their retail network, and support production companies, sales companies, professional recycling companies and secondary lead companies to jointly build a recycling network.
