Gerenciamento de resíduos sólidos na construção civil em Alegrete/RS: diagnóstico, desafios e ações de conscientização

Abstract

Civil construction is one of the economic sectors with the greatest environmental impact. The large volume of construction and demolition waste (CDW) generated in cities and its inadequate disposal are factors that intensify environmental degradation. This study aimed to diagnose the current situation of solid waste management in the construction industry in the municipality of Alegrete/RS. To achieve this, a comprehensive diagnosis was conducted, which included site visits, interviews with industry professionals, and questionnaires to collect data on current practices and difficulties encountered. The study found that lack of information and awareness regarding proper management of construction waste is a significant problem, resulting in adverse social and environmental issues. To address this, informational material focusing on proper segregation and sustainable practices for waste reduction, reuse, and recycling was developed. This material was presented to workers during site visits, highlighting the consequences of poor waste management, the importance of proper waste management, and the benefits of adopting sustainable practices. The study also emphasized the need for a more integrated approach to waste management, involving collaboration among all stakeholders, including government, construction companies, and professionals. Results revealed that the visited companies and construction sites are not managing waste in accordance with current legislation and standards. Furthermore, it was observed that construction sites are not adequately prepared to handle waste properly. Another critical factor identified was the lack of knowledge among construction workers regarding construction and demolition waste and how to manage it in na environmentally sound manner. The findings of this study contribute to the development of a more sustainable civil construction industry aimed at reducing negative impacts on the environment and public health.
