Abstract
Waste that contains fibers and combustible material is slushed in a continuous-operation high-consistency pulper () to suspend in water the fibers contained in the waste. From the pulper () are discharged substantially continuously a fiber suspension (P) through a screen plate; and non-defibrable material (R) by means of a mechanical transfer device (). The fiber suspension (P) is sorted and cleaned for use as raw material in paper or board. The non-defibrable material (R) and the rejects (R-R) separated from the fiber suspension (P) in the sorting and cleaning stages are used as fuel in energy production and/or utilized as raw material.
