According to Chestnut (1993), stacks and batteries are representations, in lesser scale and ratios of a plant, however portable, that they modify chemical energy in electric energy. Some formats, being able to be cylindrical, rectangular and buttons are presented under, according to its design. Chemical principles are friction in accordance with, being represented for letters, normally printed in the same ones, being divided in secondary primary and (reloadable). Data of 2008 of the ABINEE (Brazilian Association of the Electric and Electronic Industry) every year indicate consumptions of 1,2 billion stacks and 400 million commercialized batteries of cellular in Brazil (INDRIUNAS, 2009). Without counting on the great number of stacks counterfeited and smuggled and this number it must be well significant, thus increasing the amount of stacks that arrive the hands of the consumer. With relation to the common stacks, is esteem that each Brazilian consummates five stacks per year on average. In countries of First World the annual consumption is of bristle of 15 units (Pope-stacks Real Program of Recycling of Stacks and Batteries, 2009). Stacks and batteries are classified by its chemical composition.
Of the type primary more consumed in Brazil they are: zinc-coal, alkaline, mercury lithium, oxide, oxide of silver, zinc-argon, and of the type secondary they are: lead-acid nickel-cadmium and. Beyond the use of these chemical elements, the physical structure of the stacks and batteries possesss other composites as Mercury, Lead and Cadmium (IPT, 1995). The majority of the chemical elements gifts in the composition of stacks and batteries are harmful to the health human being and the environment (IPT, 1995). The metals weighed, Mercury, Lead and Cadmium in high doses are highly toxic, raising the probability to occur ambient liabilities. The main agent causer of this problem is the incorrect destination. The deposit in places the open sky speeds up the oxidation process, provoking the emptying of its chemical components that can contaminate bodies d? water superficial and underground, the ground and consequentemente the producers and its different trficos levels of the alimentary chain.
