Complete Integration of Tequila Industry Wastes to Produce Cellulosic Ethanol at Pilot Scale
Short Introductive summary
Agave bagasse and tequila vinasse are the main by-products of the tequila industry in Mexico and their disposal and revaluation are extremely important aspects to achieve the sustainability of the agave-tequila economic chain. The objective of this work is to use both by-products, agave bagasse and tequila vinasse, in the production of lignocellulosic ethanol at high solid loadings. Three pre-saccharification stages were carried out in a horizontal reactor to reduce the viscosity of the system and then transferred to a vertical reactor for more efficient sugar release. The hydrolysis at high solids loads allowed a sugar concentration of 126.26 g/L. The sugars were used as substrate to produce advanced ethanol, achieving 48.44 g/L of product. It was demonstrated that it is possible to combine agave bagasse and tequila vinasse to produce biofuels at technologically relevant scales.
