At the Renaissance Farie I participate in in the spring in Los Angeles county, behind the food court area there are several blue oil recycling containers in which the vendors deposit their used frying oil. I've never been around during the week when it is collected so I don't know what the end use is, but I know it is utilized somehow. From a quick internet search my best guess is biodiesel fuel.
One of my nephews was in a band. The band traveled around in a van, which was fueled by biodiesel. They actually had their own converter, which was pulled along with the band's equipment.
One night my sister (the mother of said nephew) noticed a very strong smell of Chinese food in the air. She went outside, and sure enough, the boys were using the converter, which was being fed by used cooking oil from Chinese restaurants. Once the Chinese restaurants got smart, they started locking up their used cooking oil, so they could sell it to recyclers.
