Whirlpool: a new approach to painting the clothes dryers

Forty-six Olympic-sized swimming pools: that’s how much water the environmental team at Whirlpool Corporation’s manufacturing facility in Marion (Ohio) determined they’re saving each year thanks to an innovative and resourceful approach to painting the clothes dryers that are assembled at the plant around-the-clock. “We’re always looking for opportunities to reduce our energy and resource consumption”, says Whirlpool Corporation Senior Environmental Engineer Cory Richard. He is responsible for developing sustainable solutions for Marion’s operations, including efforts to improve recycling, waste disposal, and energy usage. “The steel exterior of a dryer at Marion will go through several different treatment stages when it’s painted – he explains -. Some of these stages have chemicals. Others have water. The water helps rinse the exteriors to prevent chemicals from carrying over into other stages”. Previously, to help keep the water in the rinse cycle chilled and at a consistent temperature, it needed to be constantly refreshed, requiring 80 gallons of cool, fresh water per minute. Before 2019, the plant relied on a local water supply for the operation. After examining water usage data collected throughout the plant, Cory Richard and his team determined there was a more innovative and sustainable approach to controlling the temperature of the water. They turned to pre-existing equipment at the facility, including employing the use of an industrial chiller initially installed for another application at the plant. “Access to these resources, such as an oversized chiller, enabled us to accomplish the project quickly and successfully”, Cory Richard comments. The change has resulted in a 20 percent decrease in water usage for the plant. The engineer credits World Class Manufacturing (a Whirlpool Corporation standard designed in part to eliminate waste and loss from the production process) with Marion’s advancements in sustainability. “World Class Manufacturing is our lifeblood – he said -. While we set goals and priorities for the year, we’re looking for new sustainable solutions daily”. Cory Richard and his team have since established additional process improvements at Marion to reduce the facility’s reliance on fresh water. In all, he estimates actions such as these are saving Marion about 31 million gallons of water each year.
