However, during the process of ethanol production, large quantities of vinasse are generated which can be harmful to the biota due to its physical and chemical properties. Thus, there is a growing interest in identifying new processes for its treatment. Microbial fuel cells (MFC) are bioreactors whose technology has been considered promising for the treatment of biodegradable waste and simultaneous production of clean and sustainable energy. In this context, our study evaluated the possible application of a double chamber MFC for the vinasse treatment. We observed a reduction in chemical oxygen demand (COD) of 58.8%, and a current density of 330 mWm-2 in a period of 28 days. Taking into consideration our preliminary results, we concluded that the MFC technology presents itself as highly promising for the treatment of vinasse. However, further studies on the configuration and operation of the MFC are required for a higher number of cycles.openAccessTexto completo de eventohttps://orcid.org/0000-0002-9287-6071
