In 2007, Anheuser-Busch joined the U.S. Environmental Protection Agency’s Climate Leaders program and pledged to reduce greenhouse gas emissions from 2005 levels by five percent by 2010. Through the dedication of employees and continued use of alternative fuels, Anheuser-Busch met the goal one-year ahead of schedule and was formally recognized for its accomplishment at the annual Climate Leaders Partners meeting on Dec. 2, 2009 in National Harbor, Md. As part of receiving advanced certification of its goal from the Climate Leaders program, we committed to further decrease total greenhouse gas emissions by 15 percent by the end of 2013 based on figures from 2008.
Our operations have reduced energy use by more than 23 percent over the past 3 years and today more than 15 percent of our energy is generated from renewable resources, including biomass, solar, wind and landfill gas (that means almost one in six of our beers is brewed using alternative fuels). Examples of how our state-of-the-art breweries are using innovative ways to source energy include:
Bio-Energy Recovery Systems (BERS): Anheuser-Busch is the world’s largest operator of BERS, a method of turning the nutrients in wastewater from the brewing process into renewable biogas. First used at our New Jersey yeast facility in 1985, BERS technology is now used at ten U.S. breweries and is responsible for generating 9.5 percent of our fuel needs. Our communities also benefit from our use of BERS technology because it lowers the electricity demand on community wastewater treatment facilities by reducing organic material in the leftover water. Substituting biogas for fossil fuels also reduces brewery emissions of carbon dioxide and reduces other air pollutants that would result from community wastewater treatment facilities.
Landfill Gas: More than 58 percent of the Houston brewery’s steam requirements are supplied by capturing biogas emitted from decomposing materials at area landfills. This alternative fuel option reduces the use of fossil fuels.
Solar Power: In May 2010, Anheuser-Busch announced the installation of a solar array on the roof of our Newark, N.J. brewery. A second phase of this project was completed in Dec. 31, 2010, doubling the size of the array which has currently has more than 7,000 photovoltaic solar panels covers 130,000 square feet. At peak production, the array will be capable of covering nearly ten percent of the brewery’s electricity demand. The solar panels will produce more than 1.1 million kilowatt hours annually, which is enough to power 125 average-sized New Jersey homes for a year. When combined with the solar array at our Fairfield, CA, brewery, Anheuser-Busch is now one of the largest users of solar power in the U.S. brewing industry.
Nutri-Turf Farms: Located near the Jacksonville and Fort Collins breweries, Anheuser-Busch’s Nutri-Turf farms apply nutrient-rich leftover water from the brewing process to help grow renewable biofuel crops.
