    A reutilização dos resíduos da cana-de-açúcar para produção do etanol de 2ª geração

    Currently, the world is in a scenario with a significant increase in the demand for ethanol. At the same time, Brazil stands out as one of the countries with the greatest technological evolution regarding the manufacture of second-generation ethanol (E2G), a biofuel that limits the negative consequences on the environment. Following this bias, the present research is carried out due to the need for the use of fuels by the current society and aims to discuss, through a bibliographic survey, about the production of E2G through sugarcane residues, thus emphasizing the importance of bagasse and sugarcane straw during this process, by-products that stand out for being the most used in this process in Brazil. In addition, the steps of manufacturing second- generation ethanol are described: pre-treatment, enzymatic hydrolysis, fermentation and distillation. Finally, with a sustainable purpose, at the end of the bibliographic survey and description of the manufacturing steps, the production of 2G ethanol is carried out.

    Produção de etanol e reaproveitamento da vinhaça

    The process of producing ethanol from sugarcane is essential to Brazil’s energy mix. In the mills, the sugarcane is harvested and crushed, producing juice that, after fermentation, is converted into ethanol. However, distillation also produces vinasse, a residue that, for a long time, was seen as a waste problem. Today, we recognize its importance: vinasse is used in the fertigation of sugarcane fields, providing the soil with vital nutrients, such as potassium and sulfur. Additionally, studies are investigating alternative methods for its reuse, such as the production of lactic acid and even its conversion into green hydrogen. This reuse not only benefits the environment, but also helps the economy and sustainability of the Brazilian sugar and ethanol sector. This work aims to present the production processes and the efficiency of vinasse reuse in the industry, through a bibliographic review on the ethanol production process from sugarcane in Brazil, focusing on the investigation of vinasse reuse, evaluating its environmental and economic impacts.
