Transition to circular economy in Brazil A look at the municipal solid waste management in the state of Sao Paulo

Purpose - The purpose of this paper is to evaluate how improvements in municipal solid waste management systems (MSWMS) can contribute to a transition toward circular economy (CE) in urban areas, outlining actions and guidelines for public policies. Design/methodology/approach - The research was carried out in three municipalities located in the state of Sao Paulo in terms of: diagnosis; elaboration of more positive scenarios in terms of CE and scaling of economic and environmental benefits; and outline actions and guidelines for public policies of MSWMS. Findings - In developing countries like Brazil, MSWMS can contribute to a transition toward a CE through new public policies and management practices, or even through the improvement of those that already exist. Examples of this are the integration of the informal sector of the recycling chain and service sector related to repairs of clothing, shoes, furniture and electronics as well as composting at the food production site. This could be strengthened by legal and financial mechanisms, training and carbon credit projects. Moreover, there is a need for integration of public policies between different levels of governments and sectoral policies. Originality/value - This paper developed a methodology to examine the potential for a transition toward a CE through the MSWMS in different scenarios and cities. This methodology allows to advance the implementation of the concept of CE in urban areas of developing countries and generating co-benefits to the local economy and the global environment.

Automated summary

This paper evaluates how improvements in municipal solid waste management systems can contribute to a transition toward circular economy in urban areas, and provides guidelines for public policies to achieve this transition. In developing countries like Brazil, integrating the informal sector of the recycling chain and enhancing waste management practices can lead to a circular economy through legal and financial mechanisms, training, and carbon credit projects. Integration of public policies between different levels of governments and sectoral policies is crucial for the successful implementation of circular economy concepts in urban areas of developing countries.
