Greasezilla® is a turnkey standalone system that separates and processes FOG waste. The system’s grease-separating process enables the operator to remove FOG from the grease trap waste stream, reduce waste disposal expenses, create new revenue and run a cleaner, greener, more eco-friendly operation. No additives, additional processing, blending, or fossil fuels required.

Greasezilla® operates without dewatering, leaves nothing to be landfilled, and has a total operating cost of 1-2 cents per gallon. The separation process produces a high-quality advanced biofuel making Greasezilla® the ideal front-end pretreatment system for FOG waste.

The Greasezilla® unit runs on brown grease; about 5 percent of the brown grease produced in each batch is pumped back into the system and used as fuel.

Greasezilla® eases the financial sting of ever-increasing disposal fees, labor costs and transportation expenses associated with trips to further treatment and waste water plants. In addition, it creates new revenue streams by generating a high-quality brown grease salable commodity and through processing fees from other pumpers.

Greasezilla® also refines used cooking oil (UCO) into a premium, low-moisture yellow grease, ideal for biodiesel conversion processes.

FOG Separation Layers

The Separation Process

A standard Greasezilla® system includes dual 10,000-gallon, double-wall, insulated steel tanks. As one tank heats and separates inputs, the other can be harvested, drained and reloaded.

Greasezilla separates grease trap waste into three distinct layers:

  1. Brown Grease, approximately 8-10 percent of the finished process, is converted into a rich, advanced biofuel. Five percent of the ABF returns to fuel Greasezilla®, and the remaining 95 percent can be used for other heat requirements at the plant or as a salable fuel substitute on the commodities exchange. The low-moisture content (less than 1 percent) also makes the ABF an excellent feedstock for biodiesel conversion technologies.
  2. Batter, making up 5-10 percent of volume, can serve as an excellent feedstock for anaerobic digesters. It can also be treated with traditional processes, composted or be processed with the effluent water.
  3. Residual pasteurized water, comprising approximately 80-85 percent of the material and nearly free of suspended solids, can be safely discharged to a wastewater treatment facility.
