Circular Economy Practices in Biomass-Fired Power Plants in Brazil: An Assessment Using the ReSOLVE Framework

This study aimed to identify the adoption of circular economy (CE) practices at thermoelectric power plants (TPPs) fueled by forest biomass in Brazil and determine the degree of implementation; social, environmental, and economic impacts; motivations; challenges; and facilitating factors for the adoption of such practices. Data were collected through a questionnaire applied to a sample of 32 TPPs in Brazil employing the ReSOLVE framework from October 2023 to January 2024. The data were analyzed using descriptive statistics, with the assignment of scores, and principal component analysis. The results indicate that optimization practices are the most widespread (6.7) and sharing practices were the least adopted (4.0). The greatest motivators for adopting CE practices are promoting sustainability (9.5) and enhancing corporate image (9.5). One of the most relevant positive impacts of such practices is the improvement in social relations between companies and the community (9.1). A major challenge to CE adoption is government neglect, whereas certification systems constitute one of the major facilitators (with 20 indications). This study provides indicators for decision-makers in the private sector and public managers interested in promoting sustainable practices in the renewable energy industry.
