(Newser) – Brewer Sierra Nevada is part of an effort to turn byproducts of the beer-making process into usable, alternative fuel, CNET reports. E-Fuel sells a $10,000 portable ethanol refinery that the brewer will feed with its yearly output of 1.6 million gallons of “bottom of the barrel” waste. The company will first use the ethanol to power its own fleet, then supply workers and sell it on the market.
