    Urban development associated with economic and population growth demand greater consumption of material goods and services, leading to an increase in the generation of urban solid waste (MSW) and in the consumption of electricity. About 70% of the MSW generated in the world is still disposed of in “dumps” and/or landfills. In addition, developed and developing countries, based on the hierarchy of waste, seek new alternatives to generate value for MSW with the inclusion of the concept of circular economy suggested by the United Nations (UM) in compliance with Goals of Sustainable Development (SDGs). This evolution in the destination of MSW can occur through energy recovery from the thermal treatment of MSW, using Waste to Energy – WTE technologies. It is importance to emphasize that, considering the SDGs, especially in developing countries, such as Brazil, there is a need to understand the social inclusion of recyclable material collectors in this context. In this sense, this study proposes, in the first stage, a systematic and integrated review on the inclusion of WTE technologies in the world and in Brazil, as well as technical and regulatory aspects and an analysis of the energy potential of the regions of Brazil. In the second stage, with data from Brazil, it proposes an analysis of the financial viability of the implementation of mass burning unit, and from that, it evaluates the social impact from the perspective of stakeholders directly linked to the management and destination of MSW. Therefore, in the first stage, it was concluded that in the world there is an evolution of WTE technologies and in Brazil an embryonic phase was perceived with some legislative changes in recent years in favor of the theme, The power generation capacity was observed when WTE technologies were installed in Brazil, with a contribution of 4,86% more in the Brazilian energy matrix. In the second stage, it was noticed by the financial indicators Net Present Value (NPV) and Internal Rate of Return (IRR) that, for population groups of the National Sanitation Information System (SNIS) 5 and 6 population superior to 1.9 million inhabitants, the mass burning unit is financially viable. Benefiting the sector, in view of the financial viability in large urban centers, where there is greater activity by recyclable material collectors, it was observed by the perception of the interviewed stakeholders that collectors will have better socioeconomic and labor conditions with the implementation of WTE.
