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.

I think they own a BioPro 190 too, like the ones at http://www.springboardbiodiesel.com
