A cascade biorefinery concept was proposed for the first time to produce furfural and subsequent volatile fatty acids production using corn stover as biomass. In step, Subcritical water pre-treatment used extract from hemicellulose into liquid phase, while solid rich in cellulose lignin, fermented anaerobically second step (VFA). subcritical treatment combined with CO2 pressurizing agent both a of biomass, fraction lignocellulosic After 1h at 180 °C 50 bar, yield 29 % obtained phase. Acetic formic acid were generated side products treatment. Following this treatment, 49.4 initial solids recovered, marked reduction content (from 33 5 %) an increase 39 62 lignin 21 %). This then subjected anaerobic fermentation. Inoculum type key parameter, 12 higher when cow rumen compared digestion (AD) sludge wastewater plant. Pre-treatment did not improve organic matter biodegradation, probably due its high content. However, showed be successful consecutive two value-added low value raw material.
