FOG is a costly problem our platform can manage ---
sustainably and profitably.

In the US, almost half of all sewer blockages are caused by FOG. Blockages can cause sanitary sewer overflows, which discharge sewage into the environment without treatment. Such fatty-oriented blockages cause collection systems and wastewater treatment systems to perform well below capacity, demanding a costly and perpetual response. All in all, these blockages result in mandatory repairs that exceed $25 billion annually in the US, and exponentially more worldwide. Furthermore, FOG carries high environmental and economic costs arising from its treatment and disposal. Rethinking the way FOG is treated at wastewater treatment plants has the potential to change these facilities from net consumers of energy to energy neutral — or even to net producers of energy.


Over the past 14 years, we have developed a platform to help wastewater treatment plant operators mitigate the problems brought about by FOG, and to help them make the transition to become resource recovery facilities. Considering the origins of our company were founded at the University of Connecticut, our platform incorporates educational programming to raise both awareness and compliance among the residents and food-service establishments municipalities serve. It also:

  • Reduces high O&M costs
  • Mitigates sewer-line blockages and sanitary sewer overflows
  • Includes equipment that is cost-effectively installed at pump/lift stations throughout collection systems
  • Facilitates the monetization of FOG through the production of biodiesel
  • Eliminates landfilling and incineration of FOG – and associated environmental and economic costs
  • Provides a pathway for wastewater treatment plants to become resource recovery facilities and shift from net consumers of energy to energy neutral or net producers of energy
  • Is installed and operates without interruption to plant operations
  • Reduces carbon emissions by up to 74% when biodiesel replaces petrodiesel
  • Answers environmental-stewardship mandates
  • Provides an attractive return on investment
  • Is delivered through a high-impact deployment model – hub-and-spoke benefits broad geographic regions and enhances funding and financing profile of projects
  • Includes patented and protected intellectual property
  • Is scaleable in a virtually unlimited manner


Our FOG-To-Biodiesel system helps municipalities and industrial operators address environmental-stewardship and decarbonization mandates that have become central to public policy. Our system diverts and captures FOG, converting this (brown grease) waste onsite without interference to the operations of a plant – and in an automated and continuous-flow system — into ASTM B100 biodiesel that wastewater treatment plants can utilize to peak shave their energy consumption from the grid, or to eventually eliminate this consumption altogether. Municipalities can also utilize it to fuel their fleets and reduce respective carbon emissions by up to 74%. Biodiesel not consumed can be sold to local or regional fuel distributors for a considerable profit.

Life cycle analysis completed by Argonne National Laboratory found that emissions for 100% biodiesel (B100) are 74% lower than those from petroleum diesel. The California Air Resources Board has reported similar values for its life cycle analysis of biodiesel from various sources.

Biodiesel provides more energy than biogas: 32-35 million BTU per ton vs. 20-25 million BTU per ton, respectively. Over the past 10 years, B100 biodiesel has consistently fetched a higher price than other alternative fuels, including CNG (compressed natural gas) and LNG (liquified natural gas).

The output of biodiesel produced from waste presents a new revenue stream for municipalities in a design/build delivery model. Delivered as a turnkey service, private owners benefit from attractive cash flows. Our technology is scalable to address even the largest of municipal and industrial use cases.

FOG Management

From FOG Receiving Facilities to Grease Recovery Units, we have developed a comprehensive solution for wastewater treatment plant operators that addresses FOG management in an effective and profitable manner.

Awareness & Education

awareness & education rea systems

As engineers, we would be remiss if we didn’t identify the source of FOG-related problems – and consequently, design a solution to address it. To that end, we’ve developed educational programming that we offer free-of-charge to municipalities, so they can effectively launch campaigns to raise both awareness and compliance among the residents and food-service establishments they serve.
