In Germany, special companies are responsible for the recycling of used batteries and used household appliances, which is worth learning from China. In order to solve the problem of recovery and recycling of electronic waste and prevent harmful substances from endangering human health, the EU has issued two directives, namely, Directive on Scrapping Electronic and Electrical Equipment (WEEE) and Directive on Restricting the Use of Certain Hazardous Substances in Electronic and Electrical Equipment (ROHS). At present, the center has stored nearly 30 tons of recycled waste batteries in the storage room in Jiangbei. According to environmental professionals, it is reported that the mercury content of mercury-free batteries currently on the market is below 0.000 1%. It is reported that experts from Harbin Institute of Technology are working hard for the research on the disposal and reuse methods of waste batteries in Harbin, and are currently preparing to build a pilot treatment plant. In order to promote the dismantling of scrapped cars and environmental management of the industry, the State Environmental Protection Administration will also formulate and improve all aspects of dismantling and utilization of scrapped cars, especially the recycling of used batteries. In the future, the focus of the revision of laws and regulations will be to comprehensively consider safety, environmental protection and resource reuse, and at the same time consider the reuse of parts, and producers should reuse or recycle as much as possible. The "Circular Economy Law" will implement the "recovery deposit system", that is, the seller will be responsible for recycling the products and packaging listed in the compulsory recycling catalogue. For key products such as waste batteries and packaging, the recovery deposit can be charged according to a certain proportion of the product price. He said that the battery cases of better brands of electric vehicles are sealed once, and 90% of the old batteries will be deformed after use and cannot be reused. Lead-acid batteries are mainly composed of lead, sulfuric acid and some other metals and plastics. The random discharge of waste battery acid not only seriously pollutes soil and water sources, but also destroys air environment and ecological balance. For example, many people collect a lot of waste batteries, but they can't find a special recycling place, which will bring more pollution. It is difficult to collect and transport garbage after sorting, and the backward recycling technology is also restricting the enthusiasm of garbage sorting. Meishi Street community contacts downstream enterprises in advance, so that garbage can be used in time after classification. Known as the "environmental madman", Wang Zixin has invested 7 million yuan in battery recycling since 1999. He told reporters that at present, the government's useful garbage collection center and its own "Green Star" volunteer team of waste batteries can be recycled. Regarding the problems encountered by Ms. He, he said that according to the analysis of environmental experts, this kind of waste battery contains heavy metals such as mercury, lead, cadmium, chromium, nickel and manganese. , which not only eliminates the hard work of citizens to move heavy batteries, but also applies intelligent charging equipment to concentrate charging through professional means to prolong the service life of batteries; Centralized management is also conducive to the centralized harmless treatment and reuse of batteries. "A waste battery can kill all the fish in an acre of fish ponds, not to mention the destructive power of a group of electric car waste batteries." On the one hand, regulate the battery recycling and disposal behavior of manufacturers and distributors; On the other hand, through the establishment of a pollutant treatment center, old batteries can be turned into treasure and reused. When buying canned or boxed food and drinks, try to choose recyclable materials. The classification of domestic waste has also been rapidly upgraded from the original two categories to five categories. Waste newspapers, waste plastic bags, waste batteries and other domestic garbage are put into five trash cans respectively, and recyclable waste items are sent to the purchasing station by Liang Jia every Sunday. Non-ferrous metals, ferrous metals, plastics, glass, etc. Waste household appliances are all reusable resources; Some spare parts that are not limited by the service life, if the waste batteries in the mobile phone are recycled, how to dispose of the abandoned garbage bins are all cumulative. The person in charge of the city appearance and environmental sanitation bureau said that all garbage cans that are seriously damaged or have no reuse value will be discarded, such as various plastic bags, plastic bottles, foam plastics, disposable plastic lunch boxes and tableware, hard plastics and so on. 3. Metal: all kinds of scrap metal items, such as cans, tin cans, lead toothpaste skins, waste batteries, etc.
