Abstract [en]

The invention concerns a method for the production of cellulose pulp, in which wood raw material that principally comprises softwood, preferably in the form of cut wood chips, is treated in several stages in various treatment steps, whereby one of the stages comprises cooking the material in an alkali cooking fluid, with the aim of obtaining improved quality with respect to tensile strength, and of obtaining higher yield, whereby a controlled addition of wood raw material in the form of hardwood at an amount corresponding to 1-20% of the amount of softwood, preferably 3-15%, and more preferably at least 5%, takes place.
