Avaliação do gerenciamento de resíduos de construção civil e demolição gerados em canteiros de obras no município de Bacabal - MA

Abstract

The construction industry plays a vital role in society's development, utilizing a variety of resources to achieve results. However, this scenario promotes the generation of waste that negatively impacts the environment and compromises the comprehensive development of sustainability in civil engineering. In this context, this study seeks to evaluate the management practices used on construction sites by identifying waste types, analyzing daily management practices, and recommending best practices. To this end, a structured questionnaire was administered to construction professionals to understand their perceptions of waste management on construction sites in the region, based on a literature review and a structured interview with the Municipal Department of the Environment. The results revealed that the lack of a sanitary landfill hindered the effective implementation of management measures. It also revealed that sorting is an effective method for management within the construction site, as it facilitates the identification of materials for possible reuse or recycling. Nevertheless, it was proven that the main measure is the reduction that can be incorporated into the project planning through the use of BIM technology. The study notes that the main waste materials discarded at construction sites are masonry, wood, concrete, plaster, and plastic. Therefore, the main obstacle to implementing management measures is the culture of improper disposal. Therefore, the main solution is environmental education.
