O uso de análise multicritério para avaliação do manejo de resíduos sólidos de construção civil em construtoras de Anápolis/GO

Abstract

Environmental concern has manifested itself since the 1970s and federal entities have taken measures to reduce residual discharges that are harmful to the environment. With the significant growth of the civil construction industry, the National Council for the Environment - CONAMA acted to provide guidance on the separation, reuse and final destination of waste in a sustainable manner. The city of Anápolis is considered the "Trevo do Brasil" and regarded as the main industrial city and logistics hub in the Midwest due to its natural ease of integration with other consumer centers in the country. The city had a significant population growth that boosted the economy and led to a significant increase in civil construction. This immediately implies an increase in solid waste from this activity and its release into the environment. In this approach, concerns about waste generated by civil structures and their environmental impact led to a study using multicriteria analysis. For this, three macro criteria present in the reality of the works were selected and from them sub-criteria were established in order to obtain a ranking of relevance between them. From this, an analysis of the order in which the sub-criteria were arranged in the relevance ranking was carried out, where the environmental criteria remained at the top. Through this, it was possible to understand and be able to highlight them for possible intervention and investments in public policies in the municipality.
