My brother gets his bio fuel veg oil from a hamburger joint. People give it to him just for picking it up. He runs it in his one ton and does great with it. I think the people getting paid to haul it away are becoming upset knowing they could lose out on some business.
Brothers truck does smell like french fries and sometimnes eggrolls.
They are no longer getting paid to take it away, they have to pay for it, then they either resell it, or process it. It's called the free market. The people who are taking it *without permission* are stealing. You know a crime, could be a felony if the grease is valuable enough.
