ABSTRACT:
Methods and apparatus for recycling office waste paper and the like of the type having ink and laser print particles coated thereon. The waste paper is simultaneously pulped and ink particles dispersed by kneading the waste paper in the form of a high solids content aqueous mixture or sludge. After the simultaneous pulping and dispersing, no additional dispersion step is needed to form deinked paper stock. The high solids content aqueous mixture or sludge is diluted and forwarded to wet deinking separation devices such as a froth flotation unit or the like. The thus treated pulp is washed and results in the formation of a high quality pulp stock ready for bleaching and/or paper making procedures.
