Discover the power of bleach boosting enzymes
Best-in-class bleach boosting enzymes allow you to reduce bleach chemicals and increase brightness.
Get brighter results with less chemistry
Bleaching fiber to improve brightness and whiteness is time, energy and chemical intensive. And it may impact on regulatory compliance. Common bleaching agents include chlorine dioxide, hydrogen peroxide and caustic soda. Chlorine dioxide use is associated with chlorinated organic compounds, which affect the quality of your mill’s effluent.
Reduce your bleach plant’s chemical needs or enable new levels of brightness. Add enzymes before bleaching to enhance the bleachability of brown stock pulp. Add them after bleaching to increase brightness and optical stability in fully bleached pulp.
Boost bleach with minimal adjustment
Integrate enzymes in your process with no further CAPEX.
Make savings and debottleneck your bleach plant
Chlorine dioxide production bottlenecks can limit your bleaching capacity. You can change that by using enzymes to improve the bleachability of your pulps. That allows you to produce more bleached pulp with the same chlorine dioxide volumes. The result is a boost to your bleaching capacity and the output of your bleach plant.
Higher paper and board brightness using less
The dark brown color in unbleached chemical pulp stems from residual lignin. To meet the high brightness and whiteness often required in paper and board, mills must bleach the pulp. Bleaching agents penetrate the fiber wall to fragment, decolor and release entrapped lignin.
Xylanase action on the outer surfaces of unbleached chemical fiber opens the wall. That improves the penetration of bleaching agents as well as the diffusion of lignin from the fiber wall. Using xylanases on your unbleached fiber is a sustainable way to make bleaching chemicals more effective.
