Cogeneration Turbines Help SC Johnson Cut GHG Emissions

SC Johnson said Tuesday that it has chosen natural gas and waste methane from a public landfill over coal to power its largest manufacturing plant.

Twin cogeneration turbines produce 6.4 megawatts of electrical power to meet the average daily base-load demand for its Waxdale plant here, which produces products such as Windex glass cleaner and Scrubbing Bubbles bathroom cleaner.

"We continually look at alternative energy sources, everything from wind to biofuel, to power our manufacturing facilities and reduce our carbon footprint," said Scott Johnson, the company's vice president of global environmental and safety action. "We are committed to finding innovative solutions that will enable us to protect the planet for future generations."

The company embarked on its green energy, cogeneration project in 2003 and is now one of about 60 U.S. companies that recovers landfill methane that otherwise would have been wasted to produce green power.

Two years later, it added a second turbine that is powered by natural gas. Combined, the turbines lower the company's greenhouse gas emissions by 52,000 tons each year.

Company goals involve reducing absolute emissions from its global facilities by 12 percent below its 2000 baseline by 2011. U.S. operations are expected to lower absolute emissions below its 2005 baseline by 8 percent during the same time frame.

SC Johnson also wants to cut its solid waste, air and water emissions by 50 percent below 2000 levels at all worldwide factories by 2011. It is working to increase the amount of green power it buys for its global factories to 40 percent.

Since 2003, SC Johnson has lowered its greenhouse gas emissions from its top factories by 42 percent.

Energy at the Waxdale factory is Green-e certified.
