Abstract
The energy crisis and the search for low-cost renewable energy sources are contributing to the appealing of biogas. One of the sources applied in the production of this type of fuel is the use of organic waste, that is, transforming what would be discarded into a product with added value. Due to the importance and feasibility of obtaining this fuel, this study aimed to evaluating the electricity generation capacity via energetic use of biogas produced in a wastewater treatment plant. The wastewater treatment plant used in this study is currently in the phase project (approved by the city of Angra dos Reis). This plant has an average affluent flow of 25 l/s. Concomitantly to the study of this plant, an assessment of the region’s power was also carried out in terms of number of inhabitants to establish the potential for a likely standardization in the region’s wastewater treatment plant. In the study, the treatment plant had a production capacity of 9.69 m3/h of biogas, a potential of electricity generation of 125.22MWh/yr, considering the standardization of the sanitation this production could reach 70.67 m3/h, a potential of electricity generation of 913.48 MWh/yr. The study of economic viability, using tools such as Playback and NPV, demonstrated that the investment with the plant for the use of biogas is quite feasible. The gain from the sale of carbon credits was also assessed. In addition to being economically viable, the environmental gain is beyond measurement.
