In the reported experiments, a method for the selective recovery of various paper grades using specific surfactants has been studied. It is shown that the wettability of various papers can be controlled by regulating the type and concentration of the surfactant. This effect causes the different grades to wet and sink at distinctly different times, readily allowing separation. Bench-scale testing with cationic and anionic surfactants on several paper samples demonstrates a method by which commercial paper grades and their constituent fibers can be separated for recycling. A number of different commercial grades such as kraft bag papers, linerboard, newsprint, and others have been tested to demonstrate a commercially feasible recycling technique.
