It seems that restaurant grease, which used to be thought of mostly as trash, is now a hot commodity because of rising gas prices, according to the St Pete Times. Griffin Industries, a Kentucky-based company that collects restaurant grease in 21 different states, has complained that the drums of grease are gone by the time its workers come by to collect them.

The competition for Florida grease has become so heated that several grease collection companies are suing each other, claiming everything from theft to unfair competition. One company official from Boca Raton said he has bought $50,000 in surveillance equipment, including night-vision goggles, to try to stop all the stealing.

"I tell people every day, I'm in a war," said Pat Cassese, operations manager of Universal Grease.

How did grease get so hot? Blame it on the increase in gasoline prices.

Restaurant grease can be turned into biodiesel fuel, which produces far less air pollution than regular diesel. It has slowly gained in popularity as an alternative fuel for powering trucks, farm equipment, boats, anything with a diesel engine. Pinellas County's dump trucks burn biodiesel, as do fire trucks on Sanibel Island and military vehicles at Eglin Air Force Base in the Panhandle.

Griffin Industries has been handling restaurant grease for decades, filtering it to make "yellow grease," the basic ingredient for biodiesel.

In the past year, the price of yellow grease has climbed from just over $2 a gallon to nearly $3.50 a gallon in the Southeast, according to the Jacobsen, a Chicago agency that tracks renewable fuels. That's still below the cost of a gallon of gas.

Restaurants used to pay Griffin to pick up the grease. Now Griffin often pays them.

"Grease is no different from diamonds," Chris Griffin said. "They both have value, they're both a commodity. Right now it's the highest market I've ever seen."
