This is the talk in China now. For many years, used oiled flushed down into drains are dug out, filtered, heated and recycled for use in resturants. Each year, 200 to 300 million tonnes of such drain-recycled cooking are used in resturants. Statistically, China uses about 2500 million tonnes of cooking oil each year.
Therefore, if you are in China, 1 out of 10 dishes you had probably used cooking oil dug up from the drain.
