Abstract: A process for producing from a lignocellulosic raw material of (i) an intermediate product that is intended for the production of ethanol, containing polysaccharides, cellulose and hemicelluloses, and (ii) a product containing lignin in an aqueous solution without sulfur residue, this lignin could be precipitated. The process includes a step of pulping the raw material in an extruder at a temperature of between 60° C. and 180° C. and in the presence of a quantity of water that represents between 200% and 450% of the mass of said raw material and in the presence of a strong base at a concentration of between 0.5% and 4% relative to the volume of water.

Abstract: A method for obtaining a fermentable product intended for the production of metabolites by fermentation, includes the following steps: a) detoxification of a polluted ligno-cellulosic raw material including at least one polluting component; solid-liquid extraction in order to extract the polluting component(s) from the ligno-cellulosic raw material by solubilisation using at least one solvent; recovery of the cleaned ligno-cellulosic raw material; b) pre-treatment of the cleaned ligno-cellulosic raw material by defibration; c) enzymatic hydrolysis of the pre-treated ligno-cellulosic raw material in the presence of cellulose, and obtaining a fermentable product; d) optional purification of the resulting fermentable product. The use of the resulting fermentable product for producing metabolites by fermentation, as well as to a specific method for producing ethanol from the fermentable product are also described.
