Cooking Grease Suddenly Lures Thieves

June 22, 2008— -- Cartoon dad Homer Simpson once came up with a brilliant plan for making a quick buck.

His scheme? Stealing smelly, dirty, used kitchen grease and re-selling it for profit.

Now, with average gas prices topping $4 a gallon, it seems life is imitating cartoon.

That's because frying oil can be used to make bio-diesel, an alternative fuel that can power cars and other vehicles that driven by a diesel motor.

Only two years ago, discarded grease was sold for roughly 75 cents a gallon on the commodities market. Since then, the price has more than tripled to $2.60 a gallon.

With the gooey stuff now being something akin to liquid gold, restaurants in states from California to Florida are reporting a rise in used-grease thefts.

Nick Flores, the manager at La Pinata, a Mexican restaurant in Alameda, Calif., that serves hundreds of baskets of deep-fried golden tortilla chips each day, says he was shocked when his bins of used oil were hit by thieves.

"Grease stealing?" Flores told ABC News. "[That] would never have crossed my mind, no way."

La Pinata, which goes through about 200 gallons of vegetable oil a week and keeps its bins of discarded grease out back, used to have to pay about $160 a month to have someone haul the oil away.

Now a collection company, Blue Sky Biofuels, comes and takes the grease for free. But by the time they get to the restaurant, its operators often find the slick bins empty.

"They steal stuff that's valuable," Flores said of the thieves who steal his grease.

Amateur chemists can turn cooking oil into bio-fuel with the help of a simple conversion kit that can be bought new online for anywhere from $1,000 to $3,000. A favorite with environmental enthusiasts for years, the process has now become a hit with people ranging from small-time entrepreneurs to drivers squeezed by sky-high gas prices.

Truth be told, Flores doesn't seem too bothered by the stealth operators who take his grease in the night.

"I mean, we are just so glad we don't have to pay for it," Flores said.
