Dog droppings to power San Francisco

“Within the next few months, Norcal Waste, a garbage hauling company that collects San Francisco’s trash, 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.” [via] Link.

I’m in San Fran (with this GPS enabled dog pictured here) so I’ll try and find this park, seems better than sealing away potential power in plastic bags.
