Signature of Recalcitrant Stickies in Recycle Newsprint Mills, 1999 Recycling Symposium Proceedings

David K. Wilhelm, Stephen P. Makris, Sujit Banerjee

Samples taken from various operations at two recycle newsprint mills show that stickies agglomerate into mixtures either at, or just after, the repulper. The proportion of a mixture of polyvinyl acetate (a hot melt) and ac-rylate (a pressure-sensitive adhesive) increases progressively, and predominates in the final accepts. Hence, this mixture is concluded to be the most difficult stickie to remove in newsprint mills. The specific gravity of the stickies in the final accepts was much more temperature-sensitive than was that of water, which suggested a new cleaning strategy. Introducing a small temperature difference between two sets of cleaners should enhance cleaning efficiency since a contaminant of specific gravity of unity in one cleaner must have a different specific gravity in the other.
