Logs are steam heated and wetted in chests to soften the wood prior to peeling. The wetting process previously discharged all chest water from each batch. This required a large volume of make-up water.
Louisiana-Pacific constructed a recycling loop which continually reuses approximately 99 percent of the chest water.
Reduced the total water usage requirements of the facility as well as wastewater discharge by approximately 30,000 gallons per day or 10,950,000 gallons per year.
