Um estudo sobre o uso de biodigestores no Brasil

Abstract

The research aimed to study the use of biodigesters in Brazil, considering the most used types, their purposes, performance and acquisition conditions. Environmental problems, caused by the burning of fossil fuels and the improper waste disposal in rural areas, demand sustainable solutions that are viable, such as the use of biodigesters. Biodigesters use biomass (organic matter) to produce biogas (which can be used as electrical, thermal, fossil fuel and cooking gas alternatives) and produce biofertilizer (to be used in agriculture). In Brazil, the implementation of biodigesters was progressive, for there were not enough information and incentives. The initiative of some public-private partnerships and NGOs made it possible to disseminate the use of biodigesters to small rural producers. Thus, it was possible to conclude that this technology, which allows the use ofbiogas and bio-fertilizer, represents significant gains for rural producers and for the environment, by reducing greenhouse gases emission and minimizing soil and water pollution.
