Avaliação do potencial energético para a geração de energia elétrica do aterro sanitário CIGRES – RS

Abstract

The energy reuse plants promoting the incineration of urban solid waste are called Energy Reuse Plants, this type of power plant has the potential to meet up to 3,00% of the national demand for electricity Given this sector's potential, the electric energy potential was evaluated, how many homes can be served and the equivalent value in electric energy that can be obtained with the waste sent to the CIGRES sanitary landfill, based on data made available by the consortium located in the northwest of the State of Rio Grande do Sul and responsible for the final disposal of MSW in 31 municipalities in the region. Three possible scenarios were simulated, the first making the energy use of all the waste sent to the landfill, the second recycling 16,00% of the suitable material and the last recycling 30,00%. In the best scenario, a value of 58,774.63 kWh was obtained, enough to serve 6,603 homes, while in the scenario with 30,00% recycling this number drops to 46,193.75 kWh, providing enough for 5,190 homes. The equivalent value for these numbers using the value of electricity in the region would be BRL 25,508.19/day, in the scenario with greater energy use and BRL 20,048.08/day recycling 30,00% of the available material. However, the implementation and operation costs of this type of enterprise are currently high in the country, requiring a greater amount of solid waste to make it viable. Therefore, partnerships with other consortia should be sought to make the activity viable.
