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.
