Composição gravimétrica dos resíduos de construção civil do município de Caçapava do Sul – RS

Abstract

Civil construction is a sector that has increased over the years, as a result of the growth of disorders that this sector brings to municipalities and the environment, mainly due to lack of management. The biggest problem is the large amount of waste left over from the works, which are popularly known as debris, which when thrown in irregular places cause a major environmental problem. To try to mitigate these impacts, the federal government created resolution 307/2002, which establishes the preparation and implementation of an integrated waste management plan for the construction industry. In this way, the present work was carried out with the objective of obtaining the quantification and classification of the residues, coming from works of the municipality of Caçapava do Sul, RS, through the method of quarteamento. The waste was collected at a site used by the city council and private companies collecting construction waste. Based on this work, the resulting diagnosis was that the gravimetric composition showed that 85.62% of the generated residues refer to class A waste, which has great potential for reuse and recycling, followed by class B waste which is the Second most generated. In conclusion it is assessed the great importance for the municipality a plan of management of the residues of the civil construction, since the Resolution 307/2002 of CONAMA is not yet fully adequate.
