“…5 The vinasse from sugarcane is rich in organic matter and mineral components, 1 and its composition may vary depending on several factors, including the raw material used to produce ethanol, the distillation process employed, 4 collection method, and the technology used for the production of ethanol and determination of soil quality. 6 In addition to several studies that have evaluated the use of vinasse as a fertiliser, several other studies have evaluated its: potential use for bioremediation of soil contaminated with diesel oil, 7 mutagenic activity, 4 use in combustion processes, 8 treatments to reduce the pollution potential (e.g., biodigestion) 5,9 and the volume generated in the ethanol production process, 5 chemical composition, 10,11 use in animal feed, 11,12 biogas production, 13 biohydrogen production, 14 allelopathic activity for weed control, 15 and the evaporation and concentration of vinasse for use as fuel. 6 As vinasse is a waste product generated in high quantities by the alcohol industry (10-18 L vinasse per litre of alcohol produced), 3 it is a threat environment.…”
