Describe are methods of extracting the lipid fraction from trap grease using vegetable oil, such as vegetable oils sourced from waste cooking oil. The method includes mixing a volume of vegetable oil with a volume of trap grease. The mixture is comprised of an aqueous fraction, a solid fraction, and a lipid fraction. The mixture is heated to a temperature in a range from about 50 degrees C. to about 100 degrees C. for a period of time sufficient to extract at least 80 percent of the lipids from the trap grease. The lipid fraction is then separated from the solid fraction. The method may further include a process of producing biodiesel from the extracted lipid fraction.
