The FOG Energy System is a proven, fully automated FOG Waste receiving and pre-conditioning system used to safely generate green energy via existing anaerobic digesters and co-generation equipment. The system allows a wastewater treatment operator to scalably and continuously process and harvest energy from fats, oil and grease waste (“FOG”), including trap waste from restaurants and other sources, or grease separated from the wastewater stream at the wastewater treatment facilities. In 3 years of proven operation, the system averages more than 92,000 BTUs of methane produced from each gallon of grease processed.
Installed in conjunction with your existing anaerobic digesters, this difficult waste product will be diverted from landfills, cleanly and efficiently transformed into a green energy source, keeping harmful methane from entering earth’s atmosphere. In contrast to other approaches, the FOG Energy System can process untreated, unfiltered, unheated and unrefined FOG Waste, and do so without clogging or disrupting digester performance.
In addition to these green and economic benefits, the FOG Energy System boosts the bio-availability of FOG waste which improves digester performance. This has resulted in 30% to 50% reduced bio-solids in a wastewater treatment operation, helping municipalities fulfill their mission of keeping their communities and watersheds clean.
FOG Energy is the only commercially available grease receiving and pre-conditioning system that has been issued a patent by the United States government (US 7,485,230 B2). In addition, it’s the only disposal solution for FOG which provides a complete solution that diverts 100% of the FOG waste from landfills, operates continuously without clogging, improves digester performance, reduces residual bio-solids production and fully captures the energy potential from this hard to handle waste product.
