San Francisco to Recycle Dog Crap

Within the next few months, Norcal Waste will begin a pilot program under which it will use biodegradable bags and dog-waste carts to pick up droppings at a popular dog park.

The droppings will be tossed into a contraption called a methane digester, which is basically a tank in which bacteria feed on feces for weeks to create methane gas.

San Francisco -- named after Saint Francis, patron saint of animals -- has an estimated 240,000 dogs and cats. The animal feces make up nearly 4 percent of residential waste, or 6,500 tons a year.

Not quite Cow Fart Tycoon numbers but why not? And while we are at it, why not use the energy and nutrients in human waste as well? I guess there is always the do-it-yourself approach.

The best part of this story is looking at the titles via Google News:
