Method of processing recycled waste paper by separating fibers of different colors

摘要

A method of processing recycled waste paper includes pulping waste paper in a first drum pulper. White fibers are separated from the waste paper in a first screen drum. The white fibers are then processed by screening, cleaning, deinking and bleaching. The remaining waste paper is pulped within a second drum pulper. The brown fibers are separated from the waste paper in a second screen drum. The brown fibers are processed by screening, cleaning and bleaching.
