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.

The System and Separation Process

Greasezilla’s℠ design provides site agility, allowing the system to be placed near the source of FOG creation. A standard 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.

Once ingested, Greasezilla’s chemical-free separation process begins to divide the elements over a 24-hour period.

Greasezilla separates grease trap waste into three distinct layers:

  1. Brown Grease, approximately 5-10 percent of the finished process, is recycled into Brown Grease 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.
  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 or used for irrigation in drought-impacted regions.

Greasezilla℠ offers a practical, cost-effective, ecological system that turns FOG disposal into a significant economic opportunity.

Simple

  • Systems are available for interior or exterior placements

  • Is easy to operate and maintain
  • Is modular and designed to be expandable and scalable

Ecological

  • Removes FOG from the waste stream

  • Processes it into a biofuel, reducing greenhouse gas emissions
  • Creates pasteurized, headworks-ready effluent water
  • Creates instead of consuming resources

Efficient

  • Uses hydronic fluid rather than steam for heat transfer, eliminating scaling

  • Requires no flocculants, polymers or other costly additives
  • Exhaust emissions have no detectable color or odor
  • Burns a small fraction of the very fuel it produces
  • Processes 8-10 million gallons per year

Cost- Effective

  • Eliminates costs associated with dewatering, drying, lagooning, land applying, incinerating, composting.
  • Significantly reduces post treatment hauling volume and costs
  • Greasezilla owners capture disposal fees from area haulers
  • Generates revenue through the sale of the biofuel offtake
