Aproveitamento energético de resíduos sólidos urbanos; um estudo de prospecção tecnológica

Abstract

The management of municipal solid waste (MSW) represents a contemporary challenge, given that many human activities generate waste, often improperly disposed of. Before the final disposal of this waste in landfills, various treatments, including energy recovery, can be applied. This work aims to conduct a technological foresight study on the energy recovery of MSW, employing technological foresight to map technological developments and provide insights for planning and decision-making in this sector. The adopted methodology involves the analysis of scientific articles and patents at various levels. The evaluation of these documents incorporates parameters such as the year of publication, country of origin, type of author, and content focus. This approach seeks to provide a comprehensive understanding of trends and advancements in the field. The study data reveal that over the years interest in the area has grown, in addition to evident global participation, such as the contribution of different countries to the construction of knowledge, especially China. In this context, Brazil emerges as a country in the early stages of research development and technology application but with an increasing alignment with energy recovery practices from waste. Through the results, it was identified that the scenario of MSW energy recovery is dynamic, diversified, and filled with challenges and opportunities.
