Optimization of the supply chain for the production of biomass-based fuels and high-added value products in Mexico

In Mexico, high quantities of lignocellulosic residues are generated. Such residues can be used to produce either biofuels of other products. In this work, a mathematical model representing the supply chain for the conversion of the lignocellulosic biomass in Mexico into biofuels and high-added value products is presented. The model aims to maximize the profit while satisfying as much as possible of the gasoline demand in the country. Additionally, the effect of the variations on the availability of raw materials and the demand of products over the optimal supply chain is analyzed. According to the results, the highest profit can be obtained if the biomass is used to produce levulinic acid and furfural, satisfying all the demand. If it is desired to satisfy the demand of ethanol or butanol, the profit is reduced. Under the studied conditions, only a fraction of the alcohol demand can be covered. (C) 2020 Elsevier Ltd.
