Sierra Nevada Transforming Beer Waste into Fuel

Sierra Nevada Brewing has added to their arsenal of sustainable initiatives with their recent purchase of an EFuel 100 MicroFueler. The device produces ethanol from water, sugar and yeast – the later being something Sierra Nevada has in abundant supply. Around 1.6 million gallons of yeast are produced yearly as a byproduct of the beer brewing process. They plan on using the fuel for their company vehicles, and possibly for employee’s cars in the future. This is the latest in a long line of eco-friendly practicesused by Sierra including: solar, fuel cells, heat recovery, energy efficiency, water conservation and home made biodiesel.
