Sugarcane is a major crop produced in many tropical countries including Mexico and has been the basis of a well-established agroindustry. However, the variation in market prices and health concerns over the consumption of sugar are challenging the economics and sustainability of sugarcane growers and mills. This paper presents a techno-economic assessment of using existing production capacity of sugarcane in Mexico and the correspondent Mexican sugarcane mills for producing ethanol as gasoline oxygenate, in comparison to the export of excess sugar production. Using the most recent statistics, we found out that the bioethanol potential is of 849,260,499 L/year which can cover for 100% of the premium and magna gasoline demand in metropolitan area (MA) and 48% of premium gasoline in rest of the country areas (RoCAs) at 5.8% w/v blending (2.7% O₂ w/v). This can be done by diverting the 20% sugar production excess to ethanol with the benefit of a higher gross netback of 308.3 USD/ton of sugarcane in comparison to 222.5 USD/ton of sugarcane when it is exported. Furthermore, a minimum ethanol-selling price (MESP) of 0.5211 USD/L was estimated, showing that ethanol might be competitive against methyl tert-butyl ether (0.50 USD/L FOB Gulf price) as gasoline oxygenate agent. Decarbonizing gasoline in Mexico through the use of ethanol might allow the abatement of 5,766.8 kg CO₂/day when 20% sugar is used. Concerning the underconstruction Dos Bocas refinery in Tabasco State, southern Mexico, ethanol blend at 5.8% in gasolines might but also contribute to the abatement of 6.1% of CO₂ emissions and the required sugarcane was estimated at 1 million tons per year. All these indicate that sugarcane has a great potential as a feedstock to produce first-generation ethanol as a gasoline oxygenate agent in Mexico.

甘蔗是包括墨西哥在内的许多热带国家生产的主要农作物，并且已成为成熟的农业工业的基础。然而，市场价格的变化和对糖消耗的健康关注正挑战甘蔗种植者和糖厂的经济性和可持续性。本文介绍了利用墨西哥现有甘蔗生产能力以及与之对应的墨西哥甘蔗加工厂生产乙醇（作为汽油含氧化合物）与过剩糖产品出口相比的技术经济评估。使用最新统计数据，我们发现生物乙醇潜力为849,260,499升/年，可以满足大都市区（MA）溢价和大型汽油需求的100％，以及该国其他地区的溢价汽油的48％ （RoCA）在5.8％w / v混合下（2.7％O₂ w / v）。这可以通过将多余的20％的食糖产量转为乙醇来实现，这得益于与出口时的甘蔗的222.5美元/吨相比，高的总净回报为308.3美元/吨的甘蔗。此外，估计最低乙醇销售价格（MESP）为0.5211美元/升，表明乙醇作为汽油氧化剂可能与甲基叔丁基醚（0.50美元/升FOB海湾价格）具有竞争力。在墨西哥，通过使用乙醇使汽油脱碳，当使用20％的糖时，可以减少5,766.8 kg CO ₂ /天。关于墨西哥南部塔巴斯科州Dos Bocas炼油厂建设中的问题，汽油中乙醇含量为5.8％可能会减少6.1％的CO ₂排放量每年的排放量和所需的甘蔗估计为100万吨。所有这些表明，在墨西哥，甘蔗作为原料具有巨大的潜力，可以生产第一代乙醇作为汽油的含氧剂。
