The Effects of Preprinted Supplements on a Flotation Deinking Operation

Objective: The objective of this thesis was to see the effects of heavy offset inked supplements on a newsprint flotation deinking operation. Coated and uncoated supplements were studied separately and in combination to see what quantities could be allowed to enter into a flotation deinking process without seriously reducing the quality of the resulting paper. Goal: The goal of this thesis was to obtain a final product comparable in quality to the material in which these supplements were printed on. This study should result in the ultimate reuse of a seldom used fiber source and eliminate the added expense of separation
