Beer brewers are leveraging once wasted byproducts and reclaiming wasted heat:
- Vermont's Magic Hat Brewing Co. has installed a system (more properly known as a Biphase Orbicular Biodigester) to extract leftover barley, hops, wastewater and yeast into an anaerobic methane digester that produces natural gas.
- Anheuser-Busch is capturing heat that's generated during the brewing process to de-ice its loading dock during foul weather.
- Coors' sells its ethanol byproducts to refineries throughout Colorado.
- Some European breweries dry biomass for burning, to provide energy and heat that will brew more beer.
