With gas prices being what they are, the geopolitical situation being what it is, and the future of fossil fuels being in a very tenuous place, the news media has been filled in recent months with a lot of different schemes for renewable energy. Clean coal, ethanol, solar, wind, and biodiesel are among the options being presented by talking heads on CNN and corporate video press releases blindly aired by your local action news team. This site has been ahead of the trend, reporting
here and
there for the last few years
on various schemes to turn human and animal poop into energy. Today, obviously in honor of the
Summer Stoolstice, Fortune/CNN reports on a
few more companies trying to tap into the well of brown gold.
Cows produce eighteen gallons of poop a day. (And I thought my flu-induced diarrhea this weekend was bad!) With "Micrology" technology from a company called Environmental Power, cow poop and food waste can be digested to release methane. "One Wisconsin dairy farmer, with 875 cows, has installed a methane digester that produces enough electricity to power about 600 homes."
Adult humans only produce about a half-pound of poop a day. Nevertheless, it adds up quick. The article also discusses options for composting toilets that turn organic matter into fertilizer. The article concludes with a warning that these toilets cost upwards of $2,000; alas, it drops the ball by not mentioning Joseph Jenkins' Humanure system, which does a much better job than the fancy composting toilets, uses up a lot less real estate, requires a lot less installation, and can be installed for about 5% of the cost. The gist of his system: you poop in a bucket, cover it with sawdust, and put it in a big pile in the yard to decompose into fertilizer. (And, believe it or not, it's completely odorless!)
Babies produce god knows how much poop every day. The result: 18-20 BILLION diapers entering landfills annually. A company that can solve that problem will make a huge environmental impact indeed. Unfortunately, just because a company is marketing a clever product doesn't mean they're clever marketing people. gDiapers sells a dual diaper system in which the inner layer can be flushed with minimal environmental impact. But when asked what the "g" stands for, some buzzword-guzzling sales shill babbles that it represents "green and genuine, as well as baby-friendly words like giggle and groovy." Corporatespeak like that makes me wonder how well their product works trying to contain a spew of vomit.
