Estudo de caso: avaliação dos tipos de resíduos sólidos gerados da construção civil no município de Pombal-PB.

Abstract

The civil construction can be considered one of the two sectors with the greatest environmental impact due to the extraction of natural resources and the massive generation of waste. This sector is totally dependent on raw materials, since the extraction, production of building materials, construction itself, maintenance, renovation and demolition are generators of civil construction waste. Therefore, everything has a negative impact on the environment. This waste is often disposed of inappropriately. As a consequence, the Ordinance of the National Solid Waste Program (2012) began to require construction companies to be responsible for the correct management of this waste, in order to avoid the solid waste disposal in open spaces or other inappropriate environments. In this context, this study aims to categorize as for the composition and final disposal service of construction and demolition waste in PombalPB city. The characterization study shows the local reality and the types of solid waste from civil construction. The characterization study shows the local reality and the types of solid waste from civil construction. Twenty small and mediumsized constructions were visited, a questionnaire was applied for observation and direct classification of the composition of construction waste and photographic surveys. After a detailed study of buildings in the city, waste from classes A, B, C and D was identified. It was also verified that only 25% of construction companies are aware of the Civil Construction Waste Management Plan. Based on the results, the main waste disposal areas are irregular and do not have any management plan. In this way, alternatives were proposed for the use of these residues, one of them is as an alternative material, either in substitution to the coarse or fine aggregate, for a better management and reuse of residues, more consistent with the possibilities of the municipality, respecting the environment, and the legislation.
