General methods for Recovery of Papermaking Potential of the Recycled Fibers

Recovery of recycle potential is possible by refining, chemical additives, blending with virgin pulp and fractionation. Each method has its own advantages and disadvantages and the correct choice for a mill will depend on each mill’s particular circumstances. Among four of them, fractionation was very promising process for upgrading OCC pulp. Upgrading strength property of OCC pulp by fractionation is a routine practice in board manufacture. However, optimum use of this process is still under drastic re-evaluation. Many pilot plant trials are under way in the research labs or paper mills to attain proper procedure for fractionating OCC pulp. The following materials are presented to know more about ways of making suitable the recycled fibers for manufacturing papers with desired properties
