Brewery Waste into Ethanol Fuel

Posted on Thursday, February 5, 2009 posted by posted by Mak @ 2:23 AM

E-Fuel, a maker of home ethanol systems, and Sierra Nevada, a microbrewery in northern California, have teamed enabling the beer maker to produce its own ethanol from waste products in its brewing process. It will use E-Fuel's Efuel 100 MicroFueler to take 1.6 million gallons of unusable "bottom of the barrel" beer yeast waste, containing 5% to 8% alcohol content, so it can raise the alcohol level to 15 percent. This increased ethanol yield, minus water removed in the process, will become the fuel.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
