Any place that cooks food commercially and has deep fryers also has tanks out back to dispose of the grease. They pay for the service so often you are able to get Waste Veggie oil from these places for free or possibly a small cost.
You can also use raw veggie oil, however it has been said that WVO is more efficient because the water content has already been 'cooked' out.
