When the City of Danbury decided to renovate its wastewater treatment plant, it incorporated our FOG-To-Biodiesel system to eliminate the economic and environmental costs associated with landfilling and incinerating its FOG. The solution we proposed not only reduced their overall O&M costs, but created a new revenue stream from the valorization of this waste stream.
Our FOG-To-Biodiesel system produces premium-grade biodiesel (ASTM B100) from virtually any feedstock, including brown grease. This is a quantum leap in innovation, as all other attempts to produce biodiesel from brown grease have failed.
For this project, we designed a FOG receiving facility to increase Danbury’s capacity to accept FOG waste trucked in from food-service establishments and other sources. Our Grease Recovery Units work in tandem with our decanting process to eliminate water content and prepare the FOG for conversion into biodiesel. Water separated in the decanting process is fed into its wastewater treatment system, eliminating the need to dispose of this waste stream.
As a result of our technology, the City of Danbury is able to fuel its municipal fleets and reduce respective carbon emissions by 74%. Surplus production can be sold to fuel distributors to increase its ROI. Life-cycle analysis conducted by Argonne National Laboratory found emissions for B100 biodiesel to be 74% lower than those from petroleum diesel. The California Air Resources Board has also arrived at similar results for its life-cycle analysis of biodiesel.
