To prevent and control from the source, the introduction of mercury free batteries.
On December 31, 1997, nine ministries and commissions, including the China National Light Industry Association, the former State Environmental Protection Administration, and the State Bureau of Quality and Technical Supervision, jointly issued the "Regulations on Limiting the Mercury Content of Battery Products," requiring that the domestic production and distribution of batteries with a Mercury content greater than 0.025 tins of battery weight be prohibited by January 1, 2002. By 1 January 2006, the domestic production and distribution of alkaline zinc and manganese batteries with a Mercury content greater than 0.0001 TB was prohibited.
Since the release of the "Mercury restriction order" for batteries, our battery companies have actively reformed their production processes and improved their raw material formulas. At present, batteries produced by formal battery manufacturers have basically achieved mercury free.
National policies do not encourage centralized collection of used batteries.
The "Technical Policy on Prevention and Control of Waste Battery Pollution" jointly issued by the former State Environmental Protection Administration, the National Development and Reform Commission, the Ministry of Construction, the Ministry of Science and Technology, and the Ministry of Commerce on October 9, 2003 stipulates that at present, in the absence of effective recycling, the technical and economic conditions are under. The centralized collection of waste disposable batteries that meet national low or no mercury requirements is not encouraged.
In addition, the National List of Hazardous Wastes, issued jointly by the Ministry of Environmental Protection and the National Development and Reform Commission on June 6, 2008, stipulates that waste nickel-cadmium batteries and Mercury oxide batteries generated in daily household life can be managed without hazardous waste.
The above provisions are the requirements after the relevant departments and experts of the country have scientifically demonstrated. Waste batteries can not be uniformly recycled. The public can disperse used batteries into formal household garbage collection boxes and enter the city's regular daily garbage landfill with household waste. This will not cause environmental pollution.
Most of the commonly used dry battery pollutants are solid, and most of the harmful substances are insoluble in the battery or after disposal into the environment. The movement of pollutants from the inside to the environment or diffusion in the environment is a very slow process, especially Mercury. Therefore, the extent and extent of pollution is limited. As early as the early 1980s, the Japanese battery industry commissioned Fukuoka University to conduct a 15-year study on the migration of mercury in waste batteries. They use different landfill methods to fill waste zinc manganese, alkaline zinc manganese, Mercury oxide batteries in different landfill pillars to monitor Mercury content in the air of leakage and landfill pillars and Mercury concentration in the air when the landfill column disintegrates, A comparative analysis showed that Mercury transported with leakage in the column in 10 years accounted for only 0.08-0.1 % of the total mercury, and Mercury diffused through the atmosphere accounted for only 0.05-0.1 % of the total Mercury. The environmental impact of mercury in waste batteries in landfills is not as severe as some media have advocated.
