Abstract

As a result of a United States Postal Service (USPS) initiative, a work team was formed consisting of representatives from USPS, Forest Products Laboratory (FPL), Specialized Technology Resources, Inc. (STR), and industry. The industries represented included papermakers, paper recyclers, paper collectors, equipment manufacturers, paper users, adhesive manufacturers and chemical suppliers. The objective of the work team is to develop new and innovative solutions to problems associated with recycling paper containing pressure sensitive adhesives (PSAs). Based on criteria developed by the work team, the adhesive industry formulated new PSAs that are largely removed by screening stages of recycling processes. Protocols were also developed to evaluate newly formulated adhesives. This paper describes a pilot-scale recycling sequence used to assess removal of contaminants from feed stocks containing PSAs. The process sequence involves high consistency pulping, pressure screening, forward and reverse cleaning, and washing and flotation deinking. Fourteen newly formulated adhesives have been evaluated using this pilot-scale protocol.
