Classificação e quantificação dos resíduos de construção e demolição (RCD) e suas pontencialidades de reciclagem ou reutilização em cinco obras de edificação na cidade do Recife

Abstract

The city of Recife, region with several natural landscapes and attractive for tourism, business and leisure, has been developing annually. In most of the neighborhoods, there are large buildings being erected, leading the academic community and the state to worry about the type of policy adopted for the disposal, reuse and recycling of solid waste generated in construction, in order to avoid the environmental impact. In the Northeast Region of Brazil alone, 24,310 t / day of construction and demolition waste (CDW) were collected. Good results have already been visualized by Brazilian researchers regarding the reuse of residues, especially those of class A, generated on site. This work has proposed to classify the different types of construction and demolition waste and to indicate different forms of reuse in construction works in the city of Recife. Five (5) works were evaluated, from four (4) companies, located in different districts of Recife. To obtain the desired data, an electronic questionnaire, google forms platform, was developed by the research group. The construction traditional system of reinforced concrete was the main visualized in the works analyzed, generating as main types of residues: ceramic bricks, mortars, plaster, concrete and wood. In this work, recycling practices were verified in one of the analyzed companies, where brick and tile residues were reprocessed and used as a small aggregate for making mortars and lean concrete. However, the vast
