Abstract
The present invention relates to a process for the production of second generation biofuels and/or sugar based chemicals—for example ethanol, butanol etc—and/or materials—for example plastics, single cell proteins etc.—together with sulfonated lignin from lignocellulosic biomass, in particular from lignocellulosic biomass comprising, among others, annual plants, agricultural waste, or wood. In particular, the present invention relates to a process for the production of sugar based chemicals, biofuels or materials together with sulfonated lignin from lignocellulosic biomass comprising the pretreatment of a lignocellulosic biomass in a sulfite cooking step.
