• Comments: Annual savings from these waste reduction activities have not yet been calculated.

Details of Reductions

• Chloroform
  Comments: Many environmental benefits were realized from the project. Effluent color discharges to the Pigeon River have fallen by 75 percent. The facility now generates 57 pounds of effluent color per ton of pulp produced, down from 222 pounds at the start of the project in August 1990. Also, virtually all chloroform has been eliminated from the wastewater.

• Dioxin
  Comments: Molecular chlorine as a bleaching chemical has been eliminated and replaced with chlorine dioxide. A special design, the new 3-stage bleach plant uses only chlorine dioxide and caustic as bleaching chemicals in a chlorine dioxide - caustic extraction - chloride dioxide sequence. While dioxins had not been detected in the mill effluent for more than 4 years, this new sequence ensures that the formation of these toxic by-products of the bleaching process is even more unlikely. The mill was one of the first in the country to completely replace molecular chlorine in favor of chlorine dioxide as a bleaching agent.

• Water use
  Comments: Water usage is down from 45 million gallons per day before the modifications to current usage of less than 29 million gallons per day, a 35% reduction.
