Delware, USA – Since 2001, DuPont Titanium Technologies has saved more than $100 million through cuts in energy consumption achieved through innovation and operational changes.

The company, which is the world’s largest titanium dioxide manufacturer, reduced its energy consumption per pound of product by nearly 30 percent.

“There’s no one great ‘Eureka!’ moment in this kind of effort,” said Rick Olson, the company’s vice president and general manager. “Every one of our sites around the world is tracking down every possible opportunity to save energy. It all adds up, one motor and one valve at a time, day after day. This work is never finished.”

The company upgraded the hardware and software in its plant control rooms to give operators more detailed energy information. DuPont also invented new pigment products that can be manufactured using less energy. A new plant DuPont plans to build in China will utilize manufacturing methods that are less energy intensive.

“By 2015, we expect to be able to make twice as much titanium dioxide per unit of energy as we did in 1991,” Olsen said.
