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.

The System

A standard Greasezilla® system includes dual 10,000-gallon, double-wall, insulated steel tanks. Two tanks increase efficiency. As one tank processes the other can be harvested, drained and reloaded. A full tank weighs about 95,000 pounds, so any commercial building with a concrete slab can handle the weight. Self-contained modular systems are also available for exterior placement. The unit requires no special electrical upgrades.
