Drink beer, make fuel

Finally, a green cause the rest of us can get behind: Drinking!

"A brewing company in Chico, Calif. is adapting a new system at its brewery that will make its own high-quality ethanol fuel from discarded beer yeast.

The Sierra Nevada Brewing Co., working with the E-Fuel Corporation, will start testing the system in the second quarter of this year, and hopes to move to full-scale ethanol production in third quarter.

"This has the potential to be a great thing for the environment and further our commitment to be becoming more energy independent," said Ken Grossman, founder and president, Sierra Nevada Brewing Co.

Currently, Sierra Nevada resells almost 1.6 million gallons of unusable "bottom of the barrel" beer yeast waste to local farmers to be used as dairy feed. The waste contains 5 to 8 percent alcohol content, including enough yeast and nutrients to enable the ethanol system, the MicroFueler, to raise that level to 15 percent alcohol, allowing for an increased ethanol yield.

"Creating ethanol from discarded organic waste is an excellent example of how the MicroFueler can help eliminate our reliance on the oil industry infrastructure. This is especially true when considering Americans reportedly discard 50 percent of all agricultural farmed products," said Tom Quinn, E-Fuel founder and CEO. "Using a waste product to fuel your car is friendlier to the environment and lighter on your wallet, easily beating prices at the gas pump."

    • Hello, all
      I am not one to shy away from soda, but I have been trying to cut down/cut it out completely this year. One alternative I love is carbonated water, or club soda or seltzer, or “bubbly water” as my kids put it. I feel like I’m getting that carbonated soda-y feeling without the caffeine, sugar, or sodium. What I don’t like is buying bottles and bottles of seltzer and, even though I recycled the bottles, just felt like there could be an alternative to all the liters of water.
      Sodastream is doing just that - liberating people from plastic bottles and soda cans by allowing people to make their own sodas and carbonated water at home. If the average American consumes almost 600 cans or bottles of soda every year, more than bottled water - doesn’t it make sense to stop the cycle and make your own, avoiding the waste? Here are the amazing environmental benefits of a soda maker -
      • No batteries or electricity
      • Reduces energy used to manufacture bottles and cans
      • Reduces gas and pollution from shipping packaged beverages
      • Eliminates pollution from batteries
      I have the Pure home soda system, and I LOVE it. It doesn’t use electricity or batteries to work - just the power of carbon dioxide injected into their special water container. It’s very easy to use - install the carbon dioxide canister, fill the bottle with cold water, attach it to the system, and inject the CO2. You can leave the carbonated water as is, or add Sodastream’s large variety of soda-flavored syrups or natural essence water enhancers to give it great flavor.

    • New Belgium Brewery in Fort Collins, CO sells it's pure CO2 from the fermentation process to a nearby company who's working on algae bio-fuels. (they also make lots of yummy brew! Sunshine Wheat is a summertime favorite of mine..)

      Turns out that fermenting beer is quite possibly the best source for the purest CO2, something essential for rapid growth of algae for fuel!!

      Also, I beleive that... Wasatch Brewery here in Utah is 100% powered by wind and is actively promoting and investing in wind power.

      GO BEER!!!

    • it good that they wont sell it to farmers to feed their lifestock anymore. eating live yeast ( the bottom of barrel stuff) give you horrible gas. i would imagen that it does thesame to cow. so if they dont eat it they will produce less methane AKA green house gasses.

    • Yeah, I definitely agree that humanity wouldn't dream of giving up beer even to save the world. It would be nice if there was a way to sequestor all that co2 though.

    • Sierra Nevada is one of the greener companies out there with their methane digesters and solar panels, so it's not surprising they would be the ones doing this.

      Beer is one thing we won't give up to save the planet so you might as well make good use of the waste. I have my doubts about biofuels and buying a personal fuel station for 10 grand definitely isn't my idea of being economical, but still, it's a good concept and even if only beer manufacturers used these to fuel their company cars it would still be one step to lowering their footprint.

    • I don't quite see the logic with biofuels. Perhaps I'm looking at it wrong, but I see the production of energy by breaking down a biological product and releasing co2. How is this cleaner or really any different than a wood fire stove? Not to mention the water and energy that goes into refining the biological component into a combustible form . . .

      Also, it's worth noting that the brewery industry is pretty terrible with it's co2 emissions. Even if they had 100% clean energy input . . . the process of brewing beer requires the fermentation of sugars that releases large amounts of co2 gas.

      "Global beer consumption in 2004 was 150.392 billion liters, resulting in 9,354,382 mT of CO2 emissions."

      http://www.triplepundit.com/pages/askpablo-co2-from-beer.php

      That's the co2 emitted from just the fermentation process . . . let alone any co2 created from the huge energy demands required in the process of industrial scale production.

      I know it's difficult to get upset with breweries, after all beer is . . . beer! It's the lifeblood of parties and helps people all over the world to get laid! If any consumable product deserves the Nobel Peace Prize for it's achievements in kicking ass, it's beer.

      All that said, it's still worth to remember that the brewing process by nature has a significant carbon footprint.
