FOG is an industry-wide problem.

Greasezilla’s® FOG receiving stations are the solution.

“The system works great and answers a real need in the wastewater treatment industry. And now we can handle increased tipping fee volume and make money on the commodities sales side as well.”

– Guy Campinha, Director WCPF, Town of Wareham, MA

By separating FOG into its basic elements, Greasezilla® generates an advanced biofuel and pasteurized effluent water ready for your wastewater treatment facility.

No chemicals. No landfilling. No waste.

Greasezilla’s® two-reactor tank system heats the FOG to create separation, requiring no additives, additional processing, blending or fossil fuels. After separation, the brown grease is pumped into holding tanks and has now become an advanced biofuel that is a cleaner substitute for high-sulfur fuel. The remaining water content, which is pasteurized and nearly free of all suspended solids, is now safe for discharge into the treatment facility.

Ecological.

  • Recovers energy and water resources from the FOG waste stream.

  • Does not require polymers, flocculants or other chemicals.

  • Reduces the amount of waste heading to landfills.

  • Assists in compliance with CFR 40.403 2a and 403 5b (3).

Efficient.

  • Low operational costs.

  • Runs on 5% of the Advanced Biofuel (ABF) it produces.

  • Remote monitoring capabilities requiring minimal staffing.

  • Protects your sewer infrastructure by promoting best practices in FOG management and disposal.
  • Interior and exterior systems available for convenient installation.

Economical.

  • ROI is less than two years.

  • EBITA of 85% with low OpEx in relation to revenue.

  • Create a profitable new revenue stream by offering FOG disposal to local and regional haulers.

  • Gain additional revenue by selling the ABF on the commodities market.

  • Joint venture or direct purchase options available, including Greasezilla®-as-a-Service or Build Own Operate.

Greasezilla® separates FOG into its basic elements, sending the water back to the wastewater treatment center headworks and recovering highly profitable Brown Grease Advanced Biofuel (ABF). This end-to-end process is the most ecologically advanced system available. Greasezilla® is unique in that it is powered by the same clean ABF it produces and leaves nothing to be landfilled or disposed of.

Our customers range from small municipalities to large commercial operations. Recently, Hampton Roads Sanitation District (HRSD) selected Greasezilla® to provide FOG separations for its Nansemond Treatment Plant.

Case Study

Step One: FOG receiving

As a hub for regional grease collection, Greasezilla® technology will handle grease on the front end, assisting in compliance with EPA national pretreatment standards, including CFR 40 403.2 and CFR 40 403.5 that strive to prevent pollutants from causing obstructions and other interference that might interfere with operations.

Greasezilla® accepts grease trap waste from haulers as well as grease skimmed from scum tanks and clarifiers from other area plants. The FOG entering the system provides the raw material needed for the next step in the process.

Step Two: FOG separation

At the heart of FOG receiving stations, Greasezilla® processes the FOG into three distinct layers:

1. Brown Grease, approximately 15 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 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 effluent water, comprising approximately 80 percent of the material and nearly free of suspended solids, can be safely discharged into the wastewater treatment facility.

Step Three: Biofuel sales

As a service to our clients, Greasezilla® developed an international distribution network, a proven channel that provides the best value for the Brown Grease commodity while filling a rising demand for alternative fuels worldwide.
