Abstract

Waste is the result of processes of various activities of the community of origin: industrial, domestic, hospital, commercial, agricultural, service and the sweeping public. The residues present in the solid state, gas and liquid. Produced in all stages of human activities, waste, both in terms of composition and volume, vary depending on the consumption practices and production methods. The main concerns are facing the repercussions it can have on human health and the environment (soil, water, air and landscape). The hazardous waste generated, especially by industry, are particularly worrying because, if improperly managed, become a serious threat to the environment. Understanding the problem of garbage and the search for its resolution require more than the adoption of technologies. An action the cause of the problem requires not thinking about the garbage itself, the material aspect, but on its symbolic significance, its role and its cultural context, and also on the historical relations established by the company with its tailings. The changes are still slow in reducing the pollution potential of the Brazilian industry, mainly in relation to older industries, which continue contributing the largest share of the load generated pollution and high risk of environmental accidents, and therefore high investment needed to control and environmental costs of cleaning to control emission of pollutants, the release of effluents and irregular deposit of solid waste.
