People resort to the black market for all sorts of stolen goods: phones, watches, cars, babies. But used cooking oil? According to the Washington Post, that's a thing too.
Thieves are now moving into the green market by stealing used cooking oil from the back of restaurants. They sell the sludge to recyclers, who then process it into biodiesel. The oil can go for as much as £2.50 per gallon on the downlow.
Since this is a pretty new criminal enterprise, police aren't entirely sure what to do with the perps—or how to stop the theft from happening. In Virginia, USA, two men caught greaselifting were charged with grand larceny. Serves you right for those sticky, err, slippery fingers. [via Inhabitat]
