Sustainable management of urban solid waste

Environmental education, circular economy and public policies in Brazil

Abstract

Objective – The management of urban solid waste (USW) has become one of the biggest environmental challenges in Brazil due to population growth, rapid urbanization, and the linear consumption model. The National Solid Waste Policy (PNRS), established by Law No. 12.305/2010, aims to transform the way the country handles waste by promoting reduction, reuse, and recycling. However, its implementation faces obstacles such as the lack of effective societal participation and the deficiency of sustainable and educational practices in communities. This study aims to investigate the approaches and practices used in USW management, focusing on environmental education, circular economy, and the integration of these practices into Brazilian public policies. The general objective is to analyze the implementation of the PNRS and identify pedagogical methodologies and sustainable economic models that could contribute to the efficient management of waste. Specific objectives include (i) exploring effective pedagogical methodologies to promote environmental education, (ii) analyzing the application of the circular economy, and (iii) evaluating the advances and challenges in the implementation of the PNRS.

Methodology – The methodology adopted will be a bibliographic review of articles and empirical studies on the topic.

Originality/Relevance – The justification for this research lies in the growing environmental impact of solid waste and the need for sustainable alternatives that involve both public policies and educational practices.

Results – The study contributes to a better understanding of the challenges and possible solutions, aiming for a more inclusive and sustainable waste management system.
