Method and system for utilizing waste |
摘要 |
Waste that contains fibers and combustible material is slushed in a continuous-operation high-consistency pulper ( 10 ) to suspend in water the fibers contained in the waste. From the pulper ( 10 ) are discharged substantially continuously a fiber suspension (P<SUB>1</SUB>) through a screen plate; and non-defibrable material (R<SUB>1</SUB>) by means of a mechanical transfer device ( 22 ). The fiber suspension (P<SUB>1</SUB>) is sorted and cleaned for use as raw material in paper or board. The non-defibrable material (R<SUB>1</SUB>) and the rejects (R<SUB>2</SUB>-R<SUB>4</SUB>) separated from the fiber suspension (P<SUB>1</SUB>) in the sorting and cleaning stages are used as fuel in energy production and/or utilized as raw material.
