Abstract:
Within circular economy principles, the waste-to-energy (WtE) concept converts low-value biomass into value-added outputs, meeting the current demand for sustainable development. In the Capital of Brazil, around 3500 tons of municipal solid waste (MSW) and 7300 tons of agropastoral waste (APW), composed of crop residues and animal wastes, are generated daily. However, no specific legal destination for both residues is provided. In this context, the present work is a case study of Brazil's Federal District (FD). The main objective is to assess two WtE technologies, bio-digestion and direct combustion (incineration). Firstly, a quantitative analysis of generated MSW and APW was conducted using literature data and governmental reports. Next, the identified residues were characterized, and their energetic potential was evidenced. Then, a numerical analysis was performed to estimate energy recovery and CO2 emissions from related feedstocks. Finally, the study of the technical feasibility was determined. The obtained results reported that incineration of MSW evidenced a conversion potential of around 1950 GWh per year, with a reduction in the emission of greenhouse gases (GHG) of roughly 4E05 tons of CO2eq compared to the current management plan. For APW, bio-digestion can convert around 2020 GWh annually, reducing about 9E05 tons of GHG. Therefore, the result provides an encouraging perspective for the two valorization pathways regarding biofuels production from low-cost feedstocks for energy generation and GHG reduction.
