Composition: Laptop batteries are generators that convert chemical energy into electricity. Their chemical characteristics, can be considered harmful residues in the presence of heavy metals. Alkaline batteries are composed of manganese dioxide and zinc, and common for zinc and carbon. Regarding the micro batteries, different types: those formed by zinc-air, alkaline, silver oxide, lithium and 1as the mercury oxide, having a long list of other components. As used: Mind are primarily used battery-powered devices. As you discarded:
As the final destination of the batteries is not possible today in the country, think about recycling, leaving no alternative to storage in controlled conditions. For alkaline batteries, there is no recycling technology developed. As for mercury cells, that it is possible to recycle, the problem is that the process is extremely expensive. In the short to medium term, there is no clear alternative approach to replace other toxic metals that pose dangers, but the alternatives that have so far been handled, do not offer a universally practicable.
As contaminated: According to expert studies, a micro stack of mercury can contaminate 600,000 liters of water, a zinc-air 12,000 liters, a silver oxide battery 14,000 liters and 3,000 liters common. To decompose the protective layer that covers them, releasing the metals they contain, and where pollution occurs. How to contribute? : Campaigns to raise awareness of the damage they cause perform collection center cells
