Plastic Manufacturers Implement New Energy Efficient Technologies Into Practice in Wisconsin

MADISON, Wis., April 4, 2011 /PRNewswire/ -- With the help of Focus on Energy, Wisconsin utilities’ statewide program for energy efficiency and renewable energy, in partnership with We Energies and Xcel Energy, Xten Industries (Xten) and Pactiv Corporation (Pactiv) have implemented energy efficient emerging technologies into practice. These efforts have improved core manufacturing processes without compromising product quality and Xten and Pactiv expect to save a combined 500,000 kWh annually thanks to these efforts -- that's enough energy to power 50 homes for a year.

Newly designed radiant heater bands were installed on plastic injection machines at Xten and on a large plastic sheet extrusion machine at Pactiv. The innovative radiant heater band design addresses traditional barrel heating and cooling inefficiencies. It hastens warm-up times and can make cool-down systems more effective—saving time, energy, and money.

"We were skeptical at first that something this simple could have the projected impact. After testing and measuring the results, we hope to install them on the rest of our extruders," said Mike Arrigoni, engineer, Pactiv.

The energy efficiency efforts of implementing this technology are expected to save Pactiv and Xten more than $10,000 in energy costs each year and is equivalent to offsetting more than 197 barrels of oil from being burned—eliminating more than 169,000 pounds of carbon dioxide (CO2) from being released into the atmosphere.

In addition, variable-frequency drive hydraulic control systems were installed on eight hydraulic presses at Xten. Instantaneously Xten saw reduced energy consumption. This technology allows pump motors to run only when there is demand for hydraulic fluid instead of running at full throttle all the time.

"In the past, the motors ran flat out all the time," says Mark Dirr, director of engineering at Xten. "Now with the retrofit controls, they run just enough to get the job done. This saves a lot of electricity."

The energy efficiency efforts of implementing this technology are expected to save more than $40,000 in energy costs each year and is equivalent to offsetting more than 785 barrels of oil from being burned—eliminating more than 675,000 pounds of CO2 from being released into the atmosphere.

"We're proud of Pactiv and Xten for implementing these innovative emerging technologies into practice," said Ken Williams, Focus on Energy's business programs director. "These businesses continue to investigate new technologies and find more ways to save energy; they are positive examples for other businesses to follow."
