The analyzed biodigester is a continuous tubular model with brick concrete duct and plastic covering with a gasometer, in which the waste of 2.300 fattening pigs are deposited daily. The initial investment estimate for the installation was R$ 51.537, the system annual costs were R$ 5.700, for maintenance, R$ 4.400 for depreciation and R$ 1.370 for interests. It was found that an average consumption of 28 kW-hour-1 is the minimum that the system must reach to be economically feasible.3-14spaBiodigesterBiogasEconomic viabilityElectrical powerSwine wastesAnnual costBiodigestersElectrical power generationInvestment estimatesSwine wasteElectricityMicaEnergy conversionArtigo10.4067/S0718-07642011000400002S0718-07642011000400002Acesso aberto2-s2.0-800529494182-s2.0-80052949418.pdf0590108622967713
