ANALYSIS OF SECOND-GENERATION ETHANOL PRODUCTION ROUTES FROM LIGNOCELLULOSIC BIOMASS

Abstract

Currently, there is much discussion about sustainability and the urgency of preserving the environment for future generations, seeking alternatives that generate conscious and clean consumption worldwide. In the fuel sector, this search is no different. The increase in the price of fossil fuels, the high emission of greenhouse gases generated by burning these fuels, and their possible depletion are driving research into new technologies and renewable sources for the production of biofuels such as ethanol, which is already produced, but with the increase in its demand, studies are seeking new alternatives for its generation. In this context, the objective of this article was to evaluate the potential of lignocellulosic biomass as a raw material for the production of second-generation ethanol, studying the necessary steps and available routes for its fragmentation and subsequent fermentation.
