For many years, Pratt Industries in Conyers, GA has taken an aggressive approach to recycling. This success was achieved using several strategies including the use of a high percentage of mixed waste fiber in linerboard production combined with an anaerobic digestion process for effluent treatment. As a result of these strategies, conductivity, acidic pH and bacterial activity in the Whitewater and stock systems negatively influenced performance of the paper machine and the anaerobic digester. In 2014, mill management began to investigate the reuse of starch found in their raw material. To accomplish this, they employed the Biobond program∗ from Solenis, a novel program that combines microbiological control strategies with retention products to preserve and to retain starch in the finished recycled containerboard. This program delivered significant benefits for the papermaking process and included positive downstream effects at the anaerobic digester. An overview of the patented technology and the significant social, environmental, and economic improvements will be reviewed in this paper.
