Summary: 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.
