    Abstract: The invention relates to a method for extraction of hemicellulose, lignin and carbohydrates from a lignocellulosic biomass, wherein the method comprises: 1) extracting hemicellulose from lignocellulosic biomass, by heating lignocellulosic biomass and subcritical water to 110 - 170 ºC, under a pressure of from atmospheric pressure up to 2000 psi, and letting hemicelluloses be extracted from the biomass, leaving a first fiber residue, and 2) extracting lignin and carbohydrates from said first fiber residue, by heating said first fiber residue and said second solvent comprising ethanol and water to 110 - 170 ºC, under a pressure of from atmospheric pressure up to 2000 psi, and letting lignin and carbohydrates be extracted from said first fiber residue, leaving a second fiber residue. 2) may be performed in a plurality of static cycles. The invention further relates to a lignin obtained by said method.

    Abstract: The invention relates to a method of making an acoustic product and a novel acoustic product, wherein the acoustic product is made by adhering a facing to a first major surface of an acoustic insulation element by the use of an adhesive and curing the adhesive. The adhesive is an aqueous adhesive composition which is free of phenol and formaldehyde and comprises: - a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 2.0 mmol/g, such as 0.03 to 1.4 mmol/g, such as 0.075 to 2.0 mmol/g, such as 0.075 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins, - a component (ii) in form of one or more cross-linkers.

    Abstract: The present invention relates to a process for producing a lignin composition, which process comprises: - providing a lignin slurry comprising water and a water miscible organic solvent; - subjecting the lignin slurry to extraction at an extraction temperature of less than 100°C for an extraction time of at least 1 minute to provide an extracted slurry; - removing liquid from the extracted slurry to provide an extracted lignin; and - suspending the extracted lignin in a polar organic solvent to provide a lignin composition having a dry matter content of at least 30% by weight. The present invention also relates to a lignin composition comprising hardwood Kraft lignin and a polar organic solvent, which composition has a dry matter content of at least 30% by weight. The present invention also relates to use of the lignin composition as a fuel.
