This presentation will focus on the recommendations made by the energy team using Voith Paper to optimize the preparation of pulp for papermaking and will show the savings gained. We will review the steps that the energy team took and the methodology that led to their present day success.

The major steps:

• Initiated supplier involvement
• Changed pulping times
• Supplied two paper machines from the largest pulper
• Installed a SlushMizer™ repulping rotor and QuadraPlate™ extraction plate.

Finally, we will present the financial benefit of moving from the past practices to current operations. The utility data will be presented to show the benefits of each change which include:

• Optimizing batch pulping times
• Utilizing a single pulper to supply furnish for both paper machines
• Reducing energy requirements by converting to high performance pulper tackle
