Perspectives on the use of Bottom-Up Technologies for Converting Solid Waste Into Renewable Energy in the Context of the Urban Circular Economy

Objective: This investigation has the general objective of mapping in the literature, technologies and steps in solid waste management, which can intensify and contribute to the use and energy recovery of solid waste and its reinsertion based on circular logic for urban areas in Brazil. Theoretical Framework: The problem of waste management affects the entire ecosystem and Brazil is among the countries that most produce and irregularly eliminate solid waste. The theoretical study seeks to present the current scenario of RSU in Brazil, from the legislative aspect, circular economy concepts aligned with Lean Green in favor of sustainable development and how these concepts are aligned with current management practices in case analysis . studio in Copenhagen - Denmark. Method: The methodology adopts a qualitative character, with an exploratory and descriptive approach, a hybrid approach that combines bibliographic review, with the analysis of existing case studies. Results and Discussion: Thus, the result of the analysis is one of the main technologies and ascending practices: gasification and composting, in which the latter stands out, as well as the soil correcting properties, supporting the entire process of the material organic. waste, improves compost for the production of renewable energy and can provide adequate compost for energy production. It is concluded that the integrated approach to the circular economy, supported by Lean Green concepts and promoting technocentric management practices, is the path towards an efficient transition, promoting resource savings and sustainable development in Brazil. Implications of the investigation: The practical and theoretical implications of this investigation are discussed, providing information on how the results can apply or influence practices in the field of solid waste management, with a focus on organic waste and a focus on valorization for the production of renewable energy. These implications can contribute to the elimination of spills and sustainable development. Originality/Value: This study contributes to the literature by seeking alternatives and practices to value solid waste in order to help the production of renewable energy based on concepts that can facilitate the implementation of efficient management and its potential for savings in it urban context.
