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.
Greasezilla is available in a standard configuration (above) or in fully-enclosed modular units (below).
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:
- 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.
- 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.
- 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.
