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.
