A Kansas biodiesel maker blames skyrocketing gasoline prices for recent thefts of used cooking oil, the prime ingredient in the fuel he produces.

Healy Biodiesel president Ben Healy says that when he visits the 100 restaurants he serves, many don't have the leftover cooking oil he's there to pick up because it's been stolen.

Healy says the amount of oil stolen from his clients is in the thousands of gallons, which translates into thousands of dollars in lost revenue for his Sedgwick company.

Healy says biodiesel has caused the value of grease to triple in the past few years to 32 cents a pound. He believes that kind of money is enough to make thieves willing to tackle the messy job of stealing the old oil for the extra cash or to manufacture biodiesel.
