Cooking Oil Becomes Biofuel

The Metropolitan Environmental Trust and Tulsa Biofuels collect used cooking oil from 10 a.m. to noon Saturday, May 23, at the West Tulsa MET recycling center at 51st Street and Union Avenue, in front of Warehouse Market.
“Cooking oil, especially in large quantities, should never be placed in residential trash or poured down the drain,” says Michael Patton, executive director for The MET “Small amounts placed in the trash in a sealed container are acceptable, but large quantities can pose problems for residential plumbing, city sewers and trash haulers.”
Cooking grease is the primary cause of most residential pipeline and city sewer main blockages. This results in sewage overflows. The sewage that is spilled will eventually reach Oklahoma streams and rivers. Fats, oils and grease such as frying oil, salad oil and meat drippings are causes of this problem.
After the cooking oil waste is collected, it is taken back to Tulsa Biofuels and turned into a clean burning renewable fuel called biodiesel. Biodiesel is 70 percent cleaner than petroleum diesel and is created locally.
Saturday’s collection is open to all Tulsa residents. Commercial waste will not be accepted. Oil should be brought in a sealed plastic container. For more information about the event, call 584-0584 or visit
