Research output: Contribution to conferencePaperpeer-review

Abstract

A method for the selective recovery of various paper grades using specific surfactants has been investigated. 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. It has been 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. A number of different commercial grades, such as kraft bag papers, linerboard, newsprint, and others, have been investigated to demonstrate a commercially feasible recycling technique.
