This paper presents the potential of biogas from anaerobic digestion of vinasse and its impact in different contexts. The use of vinasse biogas (VBG) for power generation is evaluated and the potential of this energy source is compared with fossil oil power plants in terms of energy, costs and greenhouse gases (GHG) emissions in Brazil, suggesting a program where the most expensive oil power plants are replaced by biogas plants with benefits in all aspects. Secondly, the use of vinasse biomethane (VBM) to replace natural gas (NG) in the state of São Paulo is examined, presenting an incentive program that could make this alternative fuel feasible even in smaller scale plants with minimal impact on NG costs in this state, while providing considerable emission reduction. The impact of VBG considering the increase in ethanol production over the next ten years is also evaluated, showing that substantial additional energy can be obtained and larger amounts of fossil fuels can be replaced. By crossing vinasse biogas potential with selected fossil fuels demand, the article brings insights to help the transition to a low-carbon society in a novel approach. The conclusions are that VBG and VBM can provide great benefits, such as USD 1 billion/year cost reductions and 6.7 million tons CO_2e/year emissions avoided by replacing fossil oil by biogas in power generation in Brazil and 3.2 million tons CO_2e/year avoided with biomethane replacing natural gas in the state of São Paulo, which, with specific programs and policies, could be achieved.

本文介绍了酒糟厌氧消化产生沼气的潜力及其在不同环境下的影响。评估了使用Vinasse沼气（VBG）发电的情况，并从能源，成本和温室气体（GHG）排放方面比较了该能源与化石能源发电厂的潜力，这是巴西最昂贵的计划。各个方面都受益的沼气厂取代了石油发电厂。其次，研究了在圣保罗州使用酒糟粕生物甲烷（VBM）替代天然气（NG）的情况，提出了一项激励计划，即使在较小规模的工厂中，这种替代燃料也能使可行，而对天然气成本的影响最小。状态，同时提供可观的减排。还评估了考虑到未来十年乙醇产量增加的VBG的影响，表明可以获得大量的额外能源，并且可以替代大量的化石燃料。通过将酿酒厂的沼气潜力与选定的化石燃料需求相结合，本文提出了一些见解，以新颖的方式帮助向低碳社会过渡。结论是，VBG和VBM可以带来巨大的收益，例如每年节省10亿美元的成本和670万吨二氧化碳在巴西，通过用沼气代替矿物油可避免_2e /年的排放，在圣保罗州可通过生物甲烷代替天然气来避免320万吨的CO _2e /年，这可以通过具体计划和政策实现。
