His truck smells like french fries

I've talked to people who do this. America generates a great deal of waste fat annually, some from restaurants and such but a lot more from the renderers -- people who collect waste products of the packing industry and dead animals, and make them into soap. There are people who are ready to make "biodiesel" commercially from this waste fat, but the renderers currently pay more. If the price of fuel rose, on the other hand, the biodiesel people would probably ramp up production, and it would be common.
Then we'd have to worry about where our soap was coming from, of course...
