The goals to reach the sustainable development using residues in the civil construction, must contemplate the recycling and the P&amp methodology; D (Research and Development), being basic for the effective market of the residues. 2. Development the support in the civil construction today is a subject of extreme importance, since the industry of the construction provokes a great ambient impact throughout all its productive chain. This includes land occupation, raw material extration, production and transport of materials, being that, the industry of the construction is one of the great collaborators of the partner-economic development. How much to the amount of materials, used for the construction of a building, they are expenses around a ton of materials, for a square meter, using great amounts of cement, sand, brita, etc. Even so, residues are generated due to the losses or wastefulnesses in this process; exactly that if it improves the quality of the process, will always have losses. The solid residues are responsible for a great ambient impact, that frequently in clandestine way, is deposited in strips of land, public areas and aterros, having its wasted potentiality.

Although this practical still to be present in the majority of the urban centers, can be said that in recent years it has diminished, in result mainly of the advance of the politics of management of solid residues. With the creation of the Resolution n. 307 of the National Advice of the Environment (CONAMA, 2002), that it determines lines of direction for an effective reduction of ambient impacts provoked by these materials, establishing that the generators are the responsible ones for the produced residue and that with priority objective must be not the generation and in case that is not possible must establish the reduction, reutilizao recycling establishing lines of direction, criteria and procedures for the management of these residues, classifying them in four different classrooms: , B, C and D Classroom? residues you reused or you recycle as aggregate (brick, concrete, etc); Classroom B? residues you reused/you recycle for other industries (plastic, paper, etc); Classroom C? residues for which viable technologies had not been developed that allow its recycling (plaster and others); Classroom D? residues dangerous (inks, solvent, etc), or contaminated (of radiological clinics, industrial installations and others).
