Vinasse is a residue from the distillation of liquor from the fermentation for sugar cane, for the production of ethanol. Its volume produced from this process is higher and the continuous flow. Vinasse is a high-risk contaminant for soils, rivers, drains, air and ecosystems. Its treatment and transformation for new products is a sustainable way is a necessity. The last decades emergent technological have emerged for the conversion of vinasse. However, due their high volume, new research are essential for the decontamination of vinasse and its conversion to new products. In this context, this work aimed at the biological conversion of vinasse through anaerobic fermentation controlled by biogas. COD, pH and biomethane were studied during anaerobic fermentation. COD showed a sharp decrease during the first days, the remained constant. The pH remained between 6 and 7.5 during fermentation. However, the production of biomethane was continuous during the fermentation time. The anaerobic fermentation shown be an important process, which can contribute to the decontamination of vinasse and allow to generate with safe, sustainable, an important biofuel and precursor of countless chemical products such as biomethane.
