Used cooking oil becomes hot theft commodity

SAN FRANCISCO — A few years ago, drums of used french fry grease were only of interest to a small network of underground biofuel brewers, who would use the slimy oil to power their souped-up antique Mercedes.
Now, restaurants from Berkeley, Calif. to Sedgwick, Kan. are reporting thefts of old cooking oil worth thousands of dollars by rustlers who are refining it into barrels of biofuel in backyard stills.
"It's like a war zone going on right now over grease," said David Levenson, who owns a grease hauling business in San Francisco's Mission District. "We're seeing more and more people stealing grease because it lets them stay away from the pump, but it's hurting our bottom line."
Levenson, who converted the engine in his '83 Mercedes to run on straight canola oil, has built up contracts to collect the liquid leftovers from 400 restaurants in the last two years.
Last week when his pump truck arrived at Thee Parkside, a dive bar known for its chili-cheese fries, his driver found someone had already helped himself to their barrel of yellow oil.
Grease is transformed into fuel through a chemical process called transesterification, which removes glycerine and adds methanol to the oil, leaving a thinner product that can power a diesel engine. Biodiesel can also be blended with petroleum diesel, and blends of the alternative fuel are now sold at 1,400 gas stations across the country.
But as the price of diesel shoots up, so, too, does the value of grease.
In the last three years, the price of soybean oil — the main feedstock for biodiesel made in the United States — has tripled. Last week, a gallon of crude soybean oil fetched 66 cents on the open market, according to the National Biodiesel Board.
Those kinds of numbers have encouraged biofuel enthusiasts to plunder restaurants' greasy waste, and have even spurred the City of San Francisco to get into the grease-trap cleaning business.
"Restaurants and staff are no longer looking at this material as trash, they're looking at is as something that's about to go into city vehicles," said Karri Ving, who runs the city's new waste cooking oil collection program. "Unless you lock down every trash can, thefts are going to happen."
Drivers for Blue Sky Bio-Fuels, a grease hauler that also manufactures biodiesel for San Francisco's municipal program, often find the 300-gallon dumpster they store outside the Oakland Coliseum nearly dry, despite the dozens of concessions stands that regularly dump their oil there. Losses at that one site alone have cost the company $3,700 in foregone oil revenues in the last year, said Wesley Caddell, the Oakland firm's business developer.
In Kansas, Healy Biodiesel reports thousands of dollars in losses from used cooking oil heists from restaurants near Sedgwick, about 20 miles north of Wichita.
Standard Biodiesel in Seattle recently started working with police to try to catch the fly-by-night home-brewers who are pilfering up to 30,000 gallons of the oil they collect from restaurants every month.
Company officials say oil rustlers typically siphon their supplies into drums of their own, which they take to backyard gins to be brewed for personal use.
As more customers seek alternatives to petroleum-based fuels, biodiesel production has grown from the grassroots to become a multimillion dollar industry. A combination of government subsidies, tax incentives and high oil prices have increased demand for ethanol and biodiesel, which can also be made from animal fat.
The National Biodiesel Board reports that U.S. production of biodiesel reached 500 million gallons last year, up from just 75 million gallons in 2005.
To manufacture the renewable fuel legally, biodiesel producers must register with the U.S. Environmental Protection Agency. Biodiesel consumers must also pay the government taxes to help with road upkeep.
So far, members of the National Biodiesel Board haven't reported feedstock thefts, but that doesn't mean they aren't happening on a small scale, said Amber Thurlo Pearson, a spokeswoman for the industry's national trade association.
"We are of course opposed to the alleged selfish, personal-use theft of feedstock that could otherwise go to make product to benefit the U.S.," Pearson said.
San Francisco started its program, SFGreaseCycle, to cut down on the millions it spends each year to dislodge fats, oils and grease clogging the sewers, Ving said. The San Francisco Public Utilities Commission eventually hopes to power its fleet of buses, fire trucks and emergency vehicles with biodiesel made from local restaurants' old oil, she said.
Currently, drivers collect about 15,000 gallons of fat and oil each month from 350 restaurants, including Enrico's, a mainstay in the Italian-themed North Beach neighborhood.
When the program started six months ago, the city picked up the old oil for free, and sold it to select licensed biofuel makers for 30 cents a gallon. Now that restaurants are supplying them with cleaner waste oil, they can get up to $1.25 a gallon, Ving said.
Those numbers — and the city's sudden move into the market — have convinced Levenson he needs to invest in padlocks to safeguard his precious grease and the barrels that hold it. Several of those have disappeared, too.
"When you're hauling grease for free, you want to make sure there's something there to pick up. Otherwise, with these prices, it's not worth your while," he said. "That said, if I wasn't doing this company, I would probably be doing the same thing as everybody else, just going to restaurants and filling up directly."
