One city’s new program is taking the mucky sink-clogging grease from restaurants and converting it into fuel for its fleet of vehicles. As David Gorn reports, it’s the first effort of its kind in the nation:
It’s 6 in the morning, and a San Francisco sewage treatment plant is already in full gear.
(sound of a truck motor)
Workers are unloading a tankful of used cooking oil from local restaurants.
(sound of a man shouting)
But soon they’ll also be picking up something a little nastier from restaurants.
“Brown grease is culled out, pumped out by grease haulers and taken out of the city, often to landfills.”
That’s Karri Ving, biofuels coordinator for the San Francisco Public Utilities Commission. She says, instead of carting that grease off to a garbage dump, it will now be converted into biofuel.
“That material, that food material, is what we’re going to condense into a putty that gets converted into road-worthy biodiesel.”
Ving says San Francisco expects to process about 10,000 gallons of the
stuff every day.
