Method for recycling waste paper e.g. newspaper, in reactor vessel for manufacturing paper, involves dispersing portion of waste paper and particles such that printing ink-, dirt and/or oil particles in waste paper are removed and crushed

摘要

The method involves providing an aqueous suspension containing 2 weight percentage to 40 weight percentage of waste paper and 1 weight percentage to 50 weight percentage of particles. A common portion of the waste paper and the particles between 20 and 30 weight percentage are dispersed such that printing ink-, dirt and/or mineral oil particles in the waste paper are removed and crushed, and attached to surface of the particles. Stirrers, kneaders, free-fall mixers, drum mixers, static mixers, extruders or blenders are used during dispersion of the common portion. The particles consist of plastic, wood, ceramic and clay minerals.
