Abstract
The production of lignocellulosic ethanol by hydrolysis has been increasingly improved and developed due mainly to the fact that it allows an increase in production without the need for greater planting of raw material. Its production techniques are still undergoing refinement, mainly in terms of yields and technical-economic viability. The sugar and alcohol industry has great potential to supply the raw materials for the production of this biofuel, and its integrated production with the production of conventional ethanol would bring great economic benefits and reduce the demand for fossil fuels. In order to compare the impacts to the environment of a biorefinery that produces only 1G ethanol with another that integrates the production of 1G with that of 2G, a life cycle analysis (LCA) was done for both cases. The results show that the 1G + 2G unit has a small advantage or disadvantage in relation to the impact categories used, but for a better evaluation of this result, economic studies and energy yields would be ideal for better planning and decision making.
