Bioethanol production from organosolv treated beech wood chips obtained at pilot scale

At the University of Boras in Sweden, researchers have scaled up second-generation bioethanol production from beech wood chips using an acetone-based organosolv fractionation process. With the help of the INFORS HT Multifors bench-top bioreactor, they confirmed high fermentation efficiency at the 10-L scale, reaching ethanol yields of up to 95% from glucose-rich C6 streams. This study illustrates how optimized biomass pre-treatment and fermentation workflows can drive more efficient and scalable biofuel production.
