Sierra Nevada Brewing Co. is working with startup E-Fuel to create gas from their brewing yeast waste.
"Starting in the second quarter, Sierra Nevada will place MicroFuelers at its Chico, Calif., brewery and make ethanol from the 1.6 million gallons of nasty bottom-of-the-barrel beer yeast waste. E-Fuel's system requires just sugar plus yeast to create ethanol, which the company claims can be made for a dollar a gallon (that's got to largely depend on the feedstock). While it sounds a lot like a backyard moonshine still, one of the product's innovations is supposedly an advanced membrane distiller that can separate water from alcohol with fewer steps and lower heat than other ethanol systems."
