Economia circular na gestão de resíduos sólidos no brasil: Oportunidades e desafios do aproveitamento energético do biogás de aterros sanitários

Abstract

The growing generation of solid waste, a social and environmental concern, motivates the search for efficient solutions. In this scenario, the Circular Economy emerges as an approach to reintegrate waste into the economy, transforming them into valuable resources. Within this context, landfill biogas stands out as a promising option for energy recovery from waste in Brazil, but it faces challenges in its development. Therefore, this study aims to analyze the opportunities and challenges of applying the circular economy through the energy utilization of landfill biogas in Brazil. To do so, it employs a research methodology involving literature review and documentary research with content analysis, utilizing journals, books, government documents, and sectoral data. An appealing scenario for the development of the landfill biogas market in the country was identified, with significant untapped potential. However, multifaceted challenges, such as a lack of incentives and clear, specific policies for the sector, as well as uncertainties regarding the economic viability of projects, need to be addressed. Thus, despite its promise, biogas requires the implementation of measures to encourage its production and widespread use. While Brazil holds substantial potential in this field, overcoming structural and regulatory obstacles is crucial to effectively capitalize on these opportunities.
