How do you heat more with less? Reuse the heat you have.

That is what our Rothschild, Wisconsin, mill did by installing a heat exchanger to warm incoming process water with outgoing process water. The idea is simple. Instead of being lost to the wastewater treatment plant, some of the heat from the outgoing water is captured and sent back into the mill.

THE HEAT EXCHANGER HAS REDUCED THE MILL’S STEAM DEMAND BY A WHOPPING 10 PERCENT DURING THE WINTER MONTHS.

One megawatt. That’s the equivalent of the average yearly electricity consumption of 9,733 homes in India. That’s also the size of Whirlpool India’s newest solar array installation at its Pune, Maharashtra plant, helping to offset the plant’s electricity needs by more than 15 percent.

Domtar uses water for more than making paper. In our mill in Johnsonburg, Pennsylvania, we also hatch and rear fish—thousands of brook, brown and rainbow trout every year.

About 25-30 volunteers feed the fish twice a day and keep an eye on their health. Some are current mill employees; others are retirees who enjoy coming back to lend a hand.

When the trout reach an appropriate size, they are released into area streams. About 10,000 are released each year.

The safety and health of our colleagues is of primary importance. Keeping our people safe and healthy enables them to be productive members of their families, communities and our company.
