Sustentabilidade na construção civil: estudo de caso sobre o gerenciamento dos resíduos da construção em uma obra horizontal em Aparecida de Goiânia-GO.

Abstract

The construction industry plays an essential role in economic and social development, being responsible for the creation of key infrastructure for society. However, this sector is also one of the largest generators of construction and demolition waste (CDW), which, if not properly managed, can cause environmental impacts. This study aims to analyze, through a case study in Aparecida de Goiânia - Goiás, the current management of construction and demolition waste, considering the existing environmental awareness scenario. The study seeks to quantify the waste predicted in the waste management plan and compare it with the actual volume generated, to identify discrepancies and opportunities for improvement in the management process. To do this, a systematic literature review on the subject is conducted, the effectiveness of the current waste management method is evaluated, considering compliance with legislation, operational efficiency, and environmental impacts, as well as identifying strengths and potential improvements. As a regulatory framework, the CONAMA Resolution No. 307/2002 is adopted, which classifies construction and demolition waste according to its origin, composition, and environmental risk, the National Solid Waste Policy (Law No. 12.305/2010), which establishes the mandatory waste management plan for large generators, and the NBR 10004/2004, which regulates the classification of solid waste. The results point to challenges in the effective implementation of the waste management plan, as well as discrepancies in the results, highlighting that improvements in the internal strategies of companies and stricter regulations are essential for waste management. Furthermore, it suggests enhancements in waste management, especially in terms of the use of the management system, mapping, and classification of the waste.
