Economic and Financial Viability of Digester Use in Cattle Confinement for Beef

Abstract

This research analyzes the economic and financial feasibility of implementing a biodigester for confinement of beef cattle on a farm located in the State of São Paulo, through the approach of discounted cash flow. The anaerobic digestion technology arouses interest, due to its advantages with the generation of electricity and the pollution reduction of water resources, soil and air, from the biogas and bio-fertilizer production, high value-added products to cattle raising. It was verified that the treatment system of cattle manure with biodigesters generate biogas and fertilizer as revenue, with free cash flows that enable a return on investment in 3.8 years and return an IRR 26.40% and an MIRR of 10.69%; all above than the minimum rate of attractiveness which confirmed the economic and financial viability of the investment.

Processing of biomethane for electricity production as a sustainable way to treat municipal organic solid waste: A case study of the Corumbataí river basin region

“…This biodigester was chosen because it is a simple model, with application in Brazil. The dimensions of the biodigesters and the values for the acquisition of the biodigesters and generators were reported by Montoro et al (2017).…”

“…Tal análise, contempla aspectos de valor financeiro e valor econômico. Os estudos dentre os diversos modelos apresentados, demonstram que há viabilidade econômica para implantação de biodigestores (Gomes & Raiher, 2013;Montoro, Santos & Lucas Junior, 2017). Entretanto, no modelo de biodigestor apresentado por Smith, Schroenn & Blignaut (2014) para atender uma família em uma casa rural na África, em que as famílias não tiverem de desembolsar nenhum aporte financeiro, o estudo demonstrou que as famílias identificaram benefícios, porém, ficou claro que só fariam o investimento se o mesmo tivesse um retorno financeiro elevado, não considerando relevante o valor econômico.…”

Aguas residuales de industria láctea como alternativa sostenible para aumentar la productividad del maíz en Perú

“…Por otro lado, existe estudios que demuestran la vialidad económica de la producción de biofertilizante a partir de estiércol bovino (Montero et al, 2017). Sin embargo, existes escasos estudios que indiquen los impactos en indicadores de producción del cultivo de maíz empleado un biofertilizante a partir de estiércol y lactosuero.…”
