O Uso de biodigestores na suinocultura como alternativa de sustentabilidade econômica: uma análise para a região da Grande Dourados, MS

Abstract

The intensification of Brazilian pig farming also promoted the production of large amounts of residual biomass (waste) that, if inadequately managed, may become a large source of pollution to the environment. The use of biodigesters in this context springs as a technological alternative to mitigate the impacts resulted from swine farms. Thus, this research aimed to evaluate the relevance of biodigesters in pig farming and the importance of recycling renewable products. It was organized into two articles. The first one in a perspective of a theoretical essay tried to show how the insertion of digesters in the pig production system was and which contributions to agribusiness, related to competitiveness in the consumer market, it brought. The second reports, by empirical and secondary data, the estimat ive of the economic viability of biogas and the use of biofertilizers under the economic aspect on the surveyed properties. The results showed the economic benefits of the biofertilizer use as organic fertilizer on the properties agricultural productions and the economic data of the viability of biogas for electricity generation.
