Brazil is the fourth largest swine producer in the world. The herd size of about 40 million animals is mainly placed in “confinement systems” in even more geographically concentrated areas, producing waste that threatens the environment. However, this waste is also a raw material source for the production of biogas, a fuel that can be converted to electrical power. In order to generate and seize it a biodigester is required, which is a device that has been deployed in Brazil since the end of the 70´s. Nevertheless, this technology is currently not well disseminated throughout the country. The aim of this essay is the understanding of the present-day situation intending to establish the constraints for the increasing of electrical power generated from biogas in Brazil. With this purpose in mind, the author contemplated a thorough description of the biogas chain for electrical power generation within the framework of the swine agroindustrial complex and, furthermore, enriched the analysis with a retrospective overview of the incentive schemes to promote the use of biodigesters in Brazil in the last 35 years. The results of this inquiry indicated that, although institutional and organizational endeavours attempting to develop projects to generate power from biogas exist, technical difficulties mainly related to the connection to the grid and a legislation that does not promote effectively these systems’ implementation thwart more consistent endeavorments. Considering that power generation from biogas has characteristics that are different compared with the generation from other renewable sources and, additionally, prevents damages to the environment, creates income, contributes to farmers’ quality of life and the diversification of the energy matrix, it should be treated separately. That been said, a recommendation shall be suggested towards the creation of a governmental program exclusive for biogas that effectively entails the promotion of such systems taking into account the reality of the swine agroindustrial complex. |
