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.ptbagaçoetanol 2gcana de açúcar.Trabalho de Conclusão de CursoENGENHARIAS::ENGENHARIA QUIMICA::TECNOLOGIA QUIMICA::ALCOOL
