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.
