Special processes – CMP General approach Chemimechanical pulping (CMP) processes based on pretreatment with sulphite chemicals are the most common ones, but processes based on other concepts have also been developed. Sulphite treatment can be applied in other stages of the process (see Chemical stage — CMP):1 between the two mechanical stages in a two-stage
