Sugarcane vinasse biogas generation: An evaluation

Vinasse is regarded as the most significant source of contamination in the sugarcane ethanol business. Vinasse may be used to make fertilizer, although it is deficient in macronutrients and micronutrients. It is, on the other hand, one of the resources with a high biogas generation potential. Vinasse biogas generation offers both economic and environmental advantages. However, since vinasse has a poor carbon-to-nitrogen ratio, it should be supplemented with complimentary materials such as animal manure, organic industrial waste, and lime fertilizers to increase biogas production. Currently, the globe produces 22.4 gigalitres of vinasse, which has the capacity to generate 407.68 gigalitres of biogas. This potential may be thought of as a major renewable energy source. This article provides an overview of the characteristics of vinasse as well as the generation of biogas from it. In addition, a discussion of the best circumstances for biogas production, biogas potential, and the benefits of biogas generation from vinasse is given.
