Any human activity is by nature generating of residues. The industrial activies are one of the great generators of residues, be solid, liquids or gaseous, which should be correctly management seeking to minimize costs and reduction of the potential generation in environmental impacts. In agreement with the law 6.938/81, that establish the National Politics of the environmental, and the 9.605/81, that´s treats of the environmental crimes, the responsibility for the repair of any environmental damage, independent of the generating fact, the company will be called to remedy any passive one generated owed to the bad administration of residues, where the responsibility of the company doesn´t cease when these leave your facilities, including your final destination. This way the recycling of materials construction should be subsidized by a much wider program, where it involves besides the processing of the residues, the recovery areas degraded with cleaning; the implantation of areas destined to the reception of materials originating from constructions, reducing the need public areas used as embankment. The development of techniques that`s seek the reduction of the environmental impacts caused so much by the generation of residues as for the extraction of natural aggregate, they are of significant importance once the effective legislation indicates this only way to be proceeded. The development of the improvement waste construction seeking the production of small recycled aggregate to be used in making of mortars and concretes in substitution, total or partial, of the sand without significant losses in the resistance to mechanical efforts.
