Waste batteries may be small, against Queshen large. However, due to pollution, waste batteries, unlike garbage, air and water pollution, as can be felt with the senses, with great secrecy, it did not receive due attention. At present, to become the production and consumption of battery power, battery waste pollution is an urgent need to address a major environmental problem.
According to environmental experts, the recovery of waste batteries per 1,000 grams of metal, which have 82 grams of mercury, 88 g of cadmium, can be said that disposal of waste battery recycling is not only dealt with pollution, but also to achieve the recycling of resources. Foreign countries on waste battery recycling and the use of great importance. Many countries in Western Europe, not only in stores, but also directly in the street are equipped with special battery recycling containers, waste batteries are 95% of the material can be recycled, especially in high value metal recycling. Foreign Secondary Lead Industry as the rapid development of the existing 55% of lead production comes from the regenerated lead. The Secondary Lead industry, waste lead-acid battery recycling processing has a large proportion. 100 kg of waste lead batteries can be recycled 50 to 60 kilograms of lead. Cadmium batteries for recycling waste treatment technology abroad has been more mature to handle 100 kg of cadmium battery scrap metal recycling is about 20 kg of cadmium, mercury batteries are mainly used for the environmentally sound processing methods to prevent pollution of the environment.
