Meet REA Resource Recovery Systems

REA Resource Recovery Systems is a technology company focused on solving an estimated $126 billion annual problem faced by wastewater treatment plants worldwide.

Billions of gallons of FOG (fats, oils, grease) are discharged into sewers annually, causing large-scale problems such as pipe blockages that lead to sanitary sewer overflows. FOG is costly to manage, treat and dispose, and has a negative impact on the environment due to standard operating procedures such as landfilling and incineration.

REA’s technology diverts and captures FOG, converting this (brown grease) waste onsite — in an automated and continuous-flow system — into premium-grade biodiesel that municipalities can utilize to fuel their fleets and reduce respective carbon emissions by 74%. Surplus production can be sold to increase ROI.

With our intellectual property, developed under the auspices of the University of Connecticut over the past 14 years, wastewater treatment plants can now eliminate the economic and environmental costs associated with FOG disposal, while addressing environmental-stewardship and decarbonization mandates that have become central to public policy.

Where our technology fits in and the economic and environmental benefits to municipalities.


Our technology is scalable to address even the largest of municipal and industrial use cases.
