FOG Management for Wastewater Treatment Plants

Mitigate pipe blockages and O&M costs attributed to brown grease.


Rethink the way FOG is treated.

Installation and operation of our system is non-invasive to plant operations.


FOG Management as a Service

We handle it all. No up-front purchase required.


We can help you improve the performance of your digester.

Increase volatile solids removal and biogas production by feeding it a byproduct of our biodiesel production.


We make brown grease related challenges disappear.

FOG, in general, is a pain point we can effectively alleviate with our FOG Management system. We also optimize resource recovery with our FOG-To-Biodiesel system. By converting waste FOG to biodiesel, our customers can successfully address environmental-stewardship and decarbonization mandates that have become central to public policy and create a new revenue stream from what is currently a cost.

Billions of gallons of FOG are discharged into collection systems annually, causing large-scale problems such as pipe blockages that lead to sanitary sewer overflows. FOG is also costly to manage, treat and dispose of, and has a negative impact on the environment due to standard disposal procedures such as landfilling and incineration.

Our system diverts and captures FOG in the collection system, upstream from chronically troubled areas, driving down O&M costs attributed to FOG.

Rethinking the way FOG is treated at WWTPs also has the potential to change WWTPs from net consumers of energy to energy neutral — or even to net producers of energy.

With our FOG-To-Biodiesel system, we can convert brown grease onsite, without interference to the operations of a plant, in an automated and continuous-flow process, into B100 biodiesel. Such production can be sold or utilized to generate power. Municipalities can also utilize it to fuel their fleets and reduce respective carbon emissions by up to 74%.

Developed under the auspices of the University of Connecticut over nearly 15 years, we partner with developers and operators to bring our technology to wastewater treatment plants worldwide as a service or as an installed asset.
