Paper Mill Effluent Treatment and Cardboard Strengthening

As of recently, a laccase product (Novozyme 51003) is applied for treatment of paper mill effluent. The effect of adding the laccase is to reduce the color and biochemical or chemical oxygen demand in the effluent and to improve the biological step in the sewage treatment plant, all presumably due to laccase-catalyzed polymerization of lignin components in the effluent (Henrik Lund at Novozymes A/S, personal communication, June 2006).

The laccase product is also used recently for strengthening packaging materials made from old corrugated cardboard, probably by affecting the cross-linking of cellulosic fibers via reaction with lignin components present on the fiber surfaces (Henrik Lund at Novozymes A/S, personal communication, June 2006).
