Resumo

The advancement of agricultural and industrial practices has resulted in a greater demand for energy, increasing the search for renewable sources. One solution is the production of biogas from pig waste. However, small farms face challenges in biogas production due to lack of technical assistance and improper handling, but cooperative agro-energy condominiums can mitigate these difficulties. In this context, this study aims to analyze the technical and economic feasibility, considering two scenarios of the implementation of a condominium between five rural properties located in the city of Medianeira-PR. With a herd of 9250 pigs in the finishing cycle, the estimated daily production of waste is 42.55 m3, enabling the production of 1128.23 m3/day of biogas. The two scenarios establish the transportation of the residual biomass produced in the rural properties, by means of a tanker truck, to a central biodigester to produce biogas and then the generation of electricity. In the first all the amount of manure available will be used and the biogas produced will be destined to the generation of electric energy and in the second will be generated only the amount necessary to supply the electrical consumption of the five properties, which is 420 kWh / day. Thus, in the first scenario, the total generation of electricity is 1690.10 kWh/day, four times higher than the energy consumed in the properties, causing the waste of the surplus produced. In the second scenario, only 12.77 m3/day of the disposed manure was used and the remainder, which will remain on the property, after treatment will be used as biofertilizer in the crops of the farms. As a result of the economic analysis, a payback of 9 years was obtained for the first panorama and 3 years for the second, this being the most viable scenario for implementation with a NPV of R$320,893.06 and an IRR of 103%.
