DOG FECES AND BIODEGRADABLE BAGS TO BECOME FUEL FOR METHANE DIGESTERS IN INNOVATIVE PILOT

DOG FECES AND BIODEGRADABLE BAGS TO BECOME FUEL FOR METHANE DIGESTERS IN INNOVATIVE PILOT

Based on San Francisco solid waste data, animal feces comprise nearly four percent of residential waste – approximately 6,500 tons/year. Within the next few months, Norcal Waste – a trash hauling company that is involved with food residuals composting programs – will begin a pilot which will use biodegradable bags and carts to collect droppings at a popular municipal dog park. Collected materials will become feedstock in what is considered a first-of-a-kind organic feedstock for a methane digester. Meanwhile, an Associated Press article notes that the city – named after Saint Francis, patron saint of animals – has an estimated 240,000 dogs and cats, all potential generators to supply the digester.
