A gel emulsification system and method for converting fats, oils, and grease (FOG) into a solid acceptable for landfill disposal. The method may include mixing FOG with a detergent and water to form an emulsion, adding viscosifier and a cross-linking agent to the emulsion, and mixing the emulsion and the viscosifier and cross-linking agent to form a gel. The system may include a container adapted to hold solids and liquids without leaking, a powdered detergent in the container to mix with water and a FOG to form an emulsion, and a powdered viscosifier and powdered cross-linking agent in the container adapted to thicken and cross-link the emulsion to form a gel. The gel formed passes a paint filter test (SW-846 Test Method 9095B).
