Avaliação dos resíduos de construção e demolição no município de Araraquara (SP) e oportunidades no setor

Abstract

Civil construction is responsible for using about 60% of natural resources available on the planet and 30% of carbon emissions around the world. This sector also stands out in solid residue generation with Construction and Demolition Waste (CDW), that can represent round 50% to 70% of total solid residue mass in Brazil. At this point, this study aimed to analyze the national scenario for generation and management of this type of waste, paying attention to opportunities within the waste market and analyzing real quantitative and qualitative data from the municipality of Araraquara (São Paulo State). Based on the fact that public administration shows itself as largely responsible for CDW management areas around the country as well as it shares responsability when considered Public-Private Partnerships, it is possible to visualize the high development potential of CDW Market, wich had its financial turnover estimated at approximately 230 billion reais in 2019. Given the environmental impact of the civil construction sector, reinserting these materials on the market may be interesting. However, it is commonly hampered by the cheap value of transportation that gives the idea that they can be only disposable. It is also possible to consider the reuse of conserved pieces as alternative solutions combined with a major social problem: the housing deficit in Brazil.
