Tagged as the Millennium Manufacturing Facility, a Midwest snack-food processing plant boasts an oven that uses 47 percent less energy than a standardized industrial one, according to Massillon, Ohio-based Shearer's Foods.

With the efficient oven and a multitude of other energy-saving details, the facility became the world's first ever platinum-certified LEED snack-food processing plant. The facility, constructed with 22 percent recycled materials, uses 30 percent less energy in manufacturing compared to industry standards. It also has T8 fluorescent lights throughout the building and installed a water-use reduction system that includes low-flow fixtures. A rainwater harvesting system collects and reuses 17,000 gallons of water each month.

Visiting the site, U.S. Energy Secretary Steven Chu called Shearer's Foods plant a model for other American businesses.

The food processor will save $280,000 a year in energy costs, according to Melissa Shearer, vice president of communications. She says the plant created 51 jobs and expects it will employ 125 people by the end of 2011.

During his hour-long visit, Chu called the Shearer family “pioneers.”
