Benefit analysis of recycling used batteries
In recent years, China's annual consumption for the production of Discount laptop battery to 120,000 tons of zinc, 200,000 tons of manganese dioxide, 20,000 tons of copper, there is a considerable amount of zinc chloride, graphite, asphalt, steel and other material. Mn and other resources need to go through mining, ore dressing, smelting and other processes was already consumed a large amount of resources, but also a certain amount of pollution generated.
Therefore, the used Laptop battery to deal with the sound and comprehensive utilization, environmental protection, the protection of significant resources to support the handling of used batteries imminent industry.
With the increase in battery consumption, improve recycling system, the experts predict that the battery recycling will lead to new business opportunities. China's production of dry batteries ranks first in the world 15 billion annual domestic consumption amounted to 7000 million.
Batteries will be used manganese, aluminum, mercury and other substances extracted, can create larger profits. Experts, to build a Dell XPS M1330 battery factory, although used to be about eight million yuan, but its revenue is very impressive, not only can enjoy the state's environmental protection enterprises preferential tax, at the same time every day as long as 100,000 to ensure the handling capacity of the battery can be 1.5-2 million profit. According to forecasts, the end of this century, China's annual consumption of the battery will reach 7.8 billion.
Recently, by the Beijing University of Science and Technology and Hebei Yixian of used batteries renewable joint treatment plant put into operation. The plant used Dell Inspiron 6400 battery scrap processing technology, is different from Japan's "wet", but also different from that of Switzerland's "dry", nor is it the joint law of wet and dry.
Its process as follows: material is broken down - chemical purification - waste water treatment, and ultimately can be recycled tin, zinc skin, such as copper material copper needle cap, and through access to high-quality electrolytic processing of zinc, manganese products, but also the recovery of mercury and iron by-product of red. The plant has a total investment of 7.8 million yuan, the design was to deal with 3,000 tons of used PowerBook G4 battery.
Supply of raw materials used battery prospects, Beijing 200 million each year battery consumption, for a total of 6,000 tons in 1999, recovered only 60 tons, the recovery rate of only 1%. 10,000 batteries a ton of weight, to achieve 3,000 tons, 100 million will need to used batteries, which means that Beijing's half used Dell laptop battery will be recycled and can be harmless treatment.
