    摘要： The invention relates to a method for producing a fiber based product, wherein the method comprises the steps of: a) applying a binder composition over a at least one surface of at least one fiber based substrate; b) determining the distribution of the applied binder composition over the en-tire at least one surface of the at least one fiber based substrate; and c) based on the determination in step b) either accepting the treated at least one fiber based substrate for the production of the fiber based product or rejecting the treated at least one fiber based substrate from the production of the fiber based product. The invention further relates to a method for producing a binder composition, to a binder composition and to a fiber based product.

    摘要： The present invention relates to a method for treating lignin, wherein the method comprises the following steps: a) dissolving lignin into an aqueous composition, which contains a compound selected from the class of phenols and alkali, while keeping the temperature of the composition at 40-85° C., wherein the alkali comprises a hydroxide of an alkali metal; and b) heating the composition at a temperature, which is higher than the temperature of the composition in step a), with the proviso that the temperature of the composition does not exceed 100° C., while keeping the pH of the composition at a pH value of 6-14.

    摘要： The invention relates to a method for recovering low molecular weight lignin from a filtrate, wherein the low molecular weight lignin includes lignin molecules having a molecular weight of 3000 g/mol or lower, wherein the filtrate is obtained from a process where lignin is precipitated from black liquor and the formed precipitate is separated therefrom by filtration resulting in the filtrate including low molecular weight lignin being formed, and wherein the method includes the following steps: a) adjusting the pH of the filtrate to a value of 3-4 for precipitating lignin in the filtrate; b) separating the precipitated lignin from the filtrate; c) reslurrying the separated lignin until the dry solids content of the slurry is 25-40 weight-% and adjusting the pH of the slurry to a value of 2-3; d) washing the slurry; and e) separating the lignin from the slurry.
