Abstract

Abstract: This paper investigates the economic and environmental feasibility of bioethanol production from Mexican lignocellulosic biomasses including wood and grass species, bagasse and crop residues. The minimum ethanol selling price (MESP) ranged between 2.05 $/gal (wheat straw) and 2.87 $/gal (coffee pulp). Based on MESP, wheat straw, rubber wood and woody biomass were at the top of the economic ranking. The environmental ranking showed that husks, woody residues and coffee pulp are the best feedstocks. Correlations to estimate ethanol yield, net electricity production, MESP and global warming potential (GWP) based on biomass composition were developed. Correlations showed that a ratio of lignin (wet basis) to the sum of cellulose and hemicellulose (dry basis), xL >0.22 is required, for both an energy balanced process and net GWP impact savings. The correlations facilitate the fast screening of lignocellulosic biomass options for bioethanol production in an integrated biorefinery. Highlights: Economic and environmental feasibility of bioethanol from lignocellulosic biomass Minimum ethanol selling price (MESP): 2.05 (wheat straw) - 2.87 $/gal (coffee pulp) Ethanol yield, MESP and global warming potential correlated to composition Correlations for fast screening of different lignocellulosic biomass options
