Environmental Stewardship Case Study:
Fuel-Grade Ethanol From Waste Beer (Waste)
Molson Coors was the nation’s first major brewer to convert its brewing by-products into fuel-grade ethanol. The company began recycling spent yeast and waste beer – beer lost during packaging or deemed below quality standards – and converting it to ethanol in 1996, in a facility owned by Merrick & Company and operated by then Coors Brewing Company.
Today the Golden ethanol facility produces approximately two million gallons of ethanol per year. The fuel-grade ethanol is then shipped directly to local refineries to be blended with gasoline. This process takes a former waste stream and turns it into a product that is friendlier to the environment and reduces our reliance on fossil fuels.
Rick Paine, Miller Coors brewing process leader notes that
The beauty of our ethanol, is that there’s no additional refining. In essence it goes straight from here to the pump.
