Wausau Paper, located in Rhinelander, uses 50 percent hardwood and 50 percent softwood in its process-furnish mix. The mix consists of all virgin fiber (non-recycled) purchased in the form of dried pulp bales. The mill wanted to cut repulping costs without compromising production. The company considered installing a new energy-efficient Voith HM repulper rotor, but had questions about the energy-savings claims and the potential risk to product quality.
