King of BERS
Through Anheuser-Busch’s award-winning Bio-Energy Recovery Systems (BERS), we actually harness renewable energy from our leftover brewery water. This complex method allows us to capture biogas from the nutrient-rich water. Our breweries then burn this renewable energy source for fuel, supplying up to 15 percent of their on-site energy needs. Last year, the energy BERS generated for our breweries was enough to heat more than 25,000 homes. We also avoided more than 258 million pounds of greenhouse gas emissions from fossil fuels by using this renewable fuel.
Today, Anheuser-Busch is the world’s largest user of BERS, which is in place at nine of our 12 U.S. breweries and also at our brewery in Wuhan, China. And we’ve been using this method for more than two decades.
We continually work to make BERS more efficient in its capture of biogas. And we champion BERS as an example of how renewable energy can be found in the most surprising places (who knew leftover brewery water could help fuel a brewery) as we keep looking for new renewable energy sources.
