FOG to Biodiesel at Wastewater Treatment Facilities

 Over 5 billion pounds of FOG (Fat, Oil & Grease) enter United States wastewater treatment facilities each year.  These facilities are tasked with the dewatering and incinerating of FOG, typically as supplemental fuel in sludge incinerators.  There is no energy recovery in this process and could be considered a missed opportunity to generate valuable biodiesel fuel.
