A treatment to remove the printing ink from wastepaper so that the secondary fibers can be reprocessed. The deinking process makes it possible for higher-grade stocks to be manufactured from recyled content. The reprocessed pulp that results is known as DIP, or deinked pulp.
A process in which most of the ink, filler, and other extraneous material are removed from printed and/or unprinted recovered paper. The result is a pulp which can be used in the manufacture of new paper, including tissue, printing, writing, and office papers.

Removal of ink and other extraneous materials from printed, reclaimed papers by mechanical disintegration and chemical treatment, with subsequent washing or flotation separation.
