LEWISTON, Idaho (From news reports) -- Clearwater Paper won the Idaho Governor's Award for Excellence in Energy Efficiency for reducing its annual energy consumption by 7.7 million kilowatt hours at its Lewiston manufacturing complex.
The power savings Clearwater Paper achieved would be enough to power 740 homes in the United States for a year.
The tissue and paperboard maker deserves recognition for pioneering smart, cost-effective energy practices, said Gov. Brad Little said in a prepared statement. "Improving energy efficiency and reducing energy consumption are the foundation of a secure future for Idaho and our country," he said.
Clearwater Paper's innovations involved changing how machines at the plant operate. The company replaced fan pump motors in a tissue machine with ones that consume less electricity. It retrofitted a fixed-speed water pumping system with one that had variable speeds.
It also adjusted paper machine pulper agitators so they could run at lower speeds 40 percent of the time when the pulper is idling. It altered a tissue machine pressure roll vacuum box so it can operate with one zone not two. That made it possible to eliminate a pump and a motor.
"Sustainability has always been woven into the fiber of our culture," said Shannon Myers, a spokeswoman for Clearwater Paper. "We work each day to reduce our environmental impacts without compromising the quality of our products."
