Method for converting waste paper products into useful forms

Abstract

Abstract A method is provided for converting waste paper materials into more useful forms for uses such as plant mulches, lightweight concrete aggregates, fertilizers, animal feeds, chemical food stock and other materials, fuels and uses such as recycling paper processes. Waste paper materials including corrugated box board, paper board, paper of all types, etc. is available as a raw material in a wide variety of forms such as sheets, bales, bundles, boxes, shavings, clippings from box making operations, magazines, newspapers, etc. and these products are much more useful for the purposes and uses mentioned after treatment and conversion into a more useful form. This conversion includes the steps of bale breaking, sorting, trimming and/or cutting these raw materials into pieces of relatively limited size for feeding across a cutter bar into a rotating knife cylinder wherein the raw materials are cut into small pieces. The small pieces are passed through a recutter screen having sizing openings and cooperating with the rotating knife cylinder for further reduction in size. Metal and other undesirable impurities are removed before cutting and again after cutting and the finished cuttings are then formed into extruded pellets under heat and pressure or the cuttings may be bagged or compressed into bales. The cuttings may also be mixed with a large variety of ingredients such as chemicals, feed supplements, additives, water, lubricants, other organic and inorganic material and then may be bagged, baled or pelleted.
