Crooks Are After the Grease From Your French Fries

The prize for the caper was more than a ton of used restaurant grease. Two men busted by police near a strip-mall dumpster in Knoxville, Tennessee, were seen March 2 siphoning the gooey waste into barrels on their truck. In the weeks before then, 44 similar thefts had been reported.

Stealing old vegetable oil that’s been used to cook chicken nuggets and French fries sounds a little gross. But a black market for the golden gunk is growing as U.S. refiners process record amounts of grease to comply with government mandates for renewable fuels. Last year, 1.4 billion pounds (635,000 metric tons) were turned into biodiesel — or 3.84 million pounds a day.

What’s different is more cooking oil is being made into fuel. It’s now the largest use for old grease, at around 30 percent of demand. A 2007 energy law calls for American cars, trucks and buses to use escalating amounts of biofuels. Most of that is corn-based ethanol used in gasoline, but refiners also are making more biodiesel. Soybean oil is the primary raw material, followed by used grease and corn oil.

This year, oil companies must use 2 billion gallons of biodiesel, the most ever, according to government data. That’s up from 1.9 billion in 2016 — and almost nothing a decade earlier.

All that demand growth has impacted prices. The benchmark for yellow grease this week was around 25 cents a pound, which is more than triple what it was in April 2000, U.S. Department of Agriculture data show. The commodity got as high as 47.75 cents in 2011, when crude oil was over $100 a barrel and the pump price of gasoline was almost $4 a gallon.

Still, old grease poses a disposal headache for restaurants, so they sign contracts with licensed collectors, who get exclusive rights to the oil if they agree to pay a small percentage of what they sell to refiners. It’s usually stored in locked dumpsters on restaurant property.

While few police departments track thefts of grease, handlers say the crimes are on the rise.

The Knoxville case was one example. At about 5:26 a.m. on March 2, two men were observed near a Wingstop Inc. restaurant using hoses to drain grease tanks. They were filling big drums in the back of an unmarked white truck, which didn’t look like the collection contractor’s vehicle, according to police reports.

The two men were arrested with what police said was 2,200 pounds of used grease valued at about $600. Both listed their residences in North Carolina, about 300 miles away. One of the accused was deported to Mexico last month, and the other was released on bond, government records show. Neither man could be reached by Bloomberg for comment.

“Anytime diesel goes up, grease goes up,” and then “the thieves come along,” said Bob Hart, a driver for DAR-PRO Solutions in Knoxville who has been a licensed collector for more than two decades. The Wingstop was one of his customers. Before the arrests, Hart said there had been 44 loads stolen in the previous few weeks.

1,000 Locks

At restaurants serviced by Buffalo Biodiesel in eastern New York, Ohio and Pennsylvania, grease thefts have increased. Over the past six months, Majumdar says he had to replace about 1,000 locks on customer tanks. Because the thefts come out of his pocket, Majumdar hired a private investigator two months ago to help track down bad guys. The business probably loses 20 percent of its income to illegal siphoners, and Majumdar says he’s posted a $5,000 reward for the arrest and successful conviction of culprits.

Some Midwest-based companies say thefts have involved international crime syndicates and even street gangs.

In the summer of 2015, the Plymouth Minnesota Police Department started surveillance at some local restaurants and tracked some people who were using an old white box truck that had a “Fruit Co.” sign on the side as they collected grease illicitly all over the Minneapolis area, Plymouth Police Sergeant Heath Bird said. No one was prosecuted. Authorities couldn’t justify the time and resources to pursue a case involving stolen trash, Bird said.

“At the end of the day, no one cares about used grease,” Buffalo Biodiesel’s Majumdar said, adding that some thefts may be licensed collectors taking from their competitors.

Brandon Foley, vice president of procurement at Sanimax, a grease collector in the Midwest and Canada, says he’s expecting an increase in thefts as the weather warms up. He’s currently on the lookout for grease grabbers traveling around in an old Pepsi truck in the middle of the night.

“This grease industry is the wild, wild west,” said Mike Kostelac, president of Millstadt, Illinois-based Ace Grease Service, which collects from restaurants in 12 states. His company’s website has a video of someone stealing their grease.
