• Abstract:

  The cultivation of sugar cane is of great importance for the country, being one of the main commodities produced in Brazil, with a fundamental role in generating jobs, the trade balance and regional development. The sustainable potential of products originating from sugar cane is highly recognized and specifically one of these by-products has been highlighted in recent years, the so-called second-generation ethanol (E2G). Therefore, the general objective of this work is to analyze the academic bibliographical production regarding second generation ethanol (E2G) between the years 2011 and 2023. 26 articles were found, 21 in Portuguese and 5 in English, which speak directly on second generation ethanol and its production aspects. It was possible to ascertain that the country has potential for E2G production, mainly due to its already outstanding production, being a world leader in this regard. Furthermore, the possibility of increasing ethanol production without increasing the sugarcane planted area is a great attraction for agents in the production chain. However, there are obstacles to be overcome in order to establish the country as a large-scale producer of E2G, especially with regard to steps such as pre-processing of the raw material.
