ESTUDO DA VIABILIDADE ECONÔMICA DO USO DO BIOGÁS, EXTRAÍDO DA SUINOCULTURA, COMO FONTE DE ENERGIA ELÉTRICA RENOVÁVEL

Abstract

The present work had at finality to develop an economic viability study of the use of biogas extracted from pig farming wastes, as a source of renewable energy. The specific objectives aimed to scale a generator group able of supplying, by anaerobic digestion, all the production of methane gas generated by biodigesters, currently installed in pig farming and turn it into electricity. The work was based on data collected in Ponta Verde s Pig Farming, located on the TETEI s farm, in the municipality of Goianápolis Goiás. The research was characterized as qualitative as it is mitigation of environmental damage, although supported by costs data. The data collection was established by direct observation and interviews with technicians and veterinarians of pig farming. It was done a quantitative research of animals in their various stages of maturation, calculating waste produced and the amount of gas generated by him. Also the costs of investments able to use all the biogas generated and the economic and financial evaluation of the project. The cost comparison between the use of new energy with conventional, shows that the new energy, will allow the swine producer a substantial economic gain, causing the pig farming is not susceptible to the vagaries of external energy, creating a better safety and guarantee in production.
