Garbage-to-gas system makes its debutThe University of California at Davis on Tuesday formally unveiled a digester that converts food scraps and other garbage into natural gas and methane. The gases can then be converted to electricity. The system, developed by the university and Onsite Power Systems, is essentially a sealed network of tubes and chambers where bacteria consume leftovers and then excrete gases. It can convert about eight tons of garbage a week and will eventually process eight tons a day, the university said. A ton of garbage provides enough electricity to power 10 average California homes for a day. Link to Story
