You are working on the “Organosolv fractionation of lignocellulosic biomass” and are at the beginning of the FLEXI-GREEN FUELS process. Could you describe in simple words the organosolv process?

Organosolv is a process in which lignocellulosic or plant biomass is treated in mixture of water with an organic solvent, typically we use ethanol at temperature normally ranging between 160 °C and 200 °C for a typical period between 15 min and 60 min, that eventually results in fractionating biomass into its major components, which are cellulose, hemicellulose and lignin. This way, we can then process those streams separately and use them in the most efficient way as feedstocks for the production of a range of green energy, chemicals and materials.
