Abstract: The invention relates to a method for bleaching mechanically defibered pulp with peroxide in alkaline conditions and for washing the bleached pulp and recovering chemicals from the spent liquor the bleaching step by concentrating and combusting the spent liquor and subsequently dissolving the ash thus formed into water. According to the invention, the alkaline conditions of the bleaching step are obtained by adding sodium aluminate to the pulp to be bleached, at least a part of the added sodium aluminate being the ash dissolved in water.

Abstract: The invention relates to a method for combusting an organic waste concentrate, which contains alkali metal compounds, under oxidative conditions for recovering the alkali metal compounds as alkali metal carbonates. According to the invention, the combustion is carried out at a temperature of at least about 850° C. The formed flue gases are cooled below a sticking temperature range of the alkali carbonates by mixing, and simultaneously water (8) is poured on the walls (9) of a cooling zone (2) at least at the sticking temperature range.

Abstract: The invention relates to acidification of soap, wherein the acidification is performed with a sodium bisulphite solution produced by absorbing the SO.sub.2 entrained in the flue gases obtained from the combustion of odor gases derived from a chemical pulp mill into an alkaline sodium solution which is NaOH or oxidized white liquor, or with a sodium bisulphite solution which is NaHSO.sub.3 -containing mother liquid obtained from SO.sub.2 or NaHSO.sub.3 acidification of soap. The acidification can be conducted in one or more steps and by the cross-current and/or counter-current method by recycling the Na.sub.2 SO.sub.3 mother liquid obtained from the acidification.
