Análise técnica para utilização de resíduos domésticos orgânicos para geração de biogás

Abstract

The increasing scarcity of non-renewable natural resources and environmental concerns have driven the development of alternative technologies, such as biomass conversion to energy. Biogas production from various substrates, including urban solid waste and effluents from sewage treatment plants, holds significant energy potential. In urban contexts, utilizing biogas in the treatment of urban solid waste emerges as a sustainable and circular alternative, particularly due to high energy consumption in urban areas. Residential condominiums, significant generators of solid waste, present an opportunity to enhance recycling processes through proper separation of organic waste, aiming for sustainable practices. The main objective of this study is to estimate biogas generation potentials and present the energy potential through the utilization of Municipal Solid Waste (MSW) produced in residential condominiums in the municipality of Ponta Grossa, Paraná. Through condominium mapping, scenario comparisons, and a barriers/opportunities analysis, this objective was achieved. With the implementation of the normative scenario, it would be possible to generate 45,50% more energy for the municipality compared to what is currently generated by the current scenario. The identified weaknesses and barriers included a lack of tax incentives, lack of awareness about the power plant, and incorrect waste segregation. The identified opportunity is that waste separation exists, and there is also interest in change from some condominiums.
