There are 82 grams of mercury, 88 grams of cadmium, can be said that recycling batteries is not only dealing with the disposal of waste sources, but also to achieve recycling of resources. As a percentage of our total 9215% of the zinc-manganese battery cells, for example, No. 1, the composition of waste manganese dioxide batteries, weight 70g, of which manganese stick 512g, zinc skin 710g, manganese powder 015g, other 32g, including useful material zinc, discharge manganese dioxide, iron, copper, mercury, and Ishiguro, accounting for 75% of the total battery can be used as the main target resource. According to the China Battery Industry Association, 2000 China's battery production figures, the only annual production of manganese-zinc batteries will consume 150,000 tons of zinc metal, manganese dioxide discharge 270,000 tons of copper metal 0.18 million tons, 160,000 tons of steel also There Ishiguro consumption. These metals are taken from the country's mineral resources, they are thrown into landfill, is it a waste of resources. According to an estimate that China produced annually 120,000 tons of used batteries recycled zinc, 20,000 tons of copper, and a large number of other substances can be used [4]. Recycling of waste batteries developed with the use of great importance. Many western European countries, not only in stores, but also directly in the street with a special battery recycling containers, waste batteries in 95% of the material can be recycled, especially heavy metal recovery value is high. Resulting in our current recycling of waste batteries state reasons: (1) people's lack of knowledge of waste battery pollution, the hazards of waste batteries is not taken seriously enough, not strong environmental awareness. Arbitrarily discarded batteries very serious problem. Even though some sites have taken the initiative to set up recycling bins, many people also do not take the initiative to be put to waste the battery. Although China's battery recycling rate is very low, but a small amount of waste batteries should be disposed of, has become a major problem recyclers. Analysis of the environmental experts believe that China has not yet established a comprehensive and effective network and system recovery, the recovery rate is not high is caused mainly deal with difficult, even up the waste battery recycling can not be disposed, in the "homeless" situation .
Nokia is also involved in numerous projects to improve the treatment of old cell phones. Including MPPI working group, the group has drafted a covering cell phone design, collection, refurbishment and recycling and other aspects of global guidelines.
