In a process to recover wood-based waste paper (M), the wastes are converted into a fibrous aqueous suspension (S) which is washed in a second stage (2) to remove foreign bodies or unwanted components. The washed suspension is fractionated in at least a two-stage process into soft fibre (F1) and hard fibre (F2) fractions. The hard fibre fraction is then especially subjected to further grinding and chopping.
