RESUMO

Case study on the application of RCD (Residues of Construction and Demolition) in the city of Piracicaba, São Paulo. These residues, popularly known as dumps, are waste from civil construction, from demolition of houses, commercial and industrial areas. It is estimated that the city of São Paulo produces approximately seventeen thousand tons of this type of residues daily. In Brazil, this accounts for 41-70 % of solid urban waste. If not reused or managed, this waste ultimately causes a negative impact on the environment and on the health of the population; it degrades urban looks and causes floods because it clogs rainwater piping. It also aggrades rivers and streams. The Environment Council has issued a resolution, named CONAMA Resolution no. 30, dated 5 July, 2002, which determines the accountability of all Cities and the Federal District for waste, and forbids waste disposal in dumps or sanitary landfills. An integrated waste management plan must be developed including construction waste and particularly waste recycling and utilization. This paper is of an environmental nature. It provides an approach to these residues, a brief review of the bibliography about its dimension and application in similar projects, it reviews its physical, mechanical and chemical characteristics to detect possible contaminants. The paper also proposes a model for sustainable waste recycling and reuse in pavement recovery carried out by maintenance teams from SEMAE (Municipal Service of Water and Sewer from Piracicaba), after intervention in water supply and sewage networks that serve the population. In this manner this case study intends to be one more tool that public and private agencies can use as a means to solve these serious problem by providing a safe solution to use these residues
