If San Francisco has so much trouble from dumped oil and grease clogging up its drains imagine what the size of the problem countrywide (or even worldwide) is?
Why doesn't San Francisco do something radical like funding a program to produce its own bio-diesel fuel from this waste and then selling it? If the city can shut restaurants down for clogging drains then it can surely offer to take the offending material of a resturant's hands for a small fee, process it and then sell it for a profit?
Remember kids, maybe there are still a few environmental problems with bio-diesel emissions, but it's still the greenest way to power a car next to electricity or hydrogen generated from renewable energy. Just why is there a huge business of drilling oil from the ground when you can just grow it in the fields?
