Danbury Becomes the First in the World to Build Revolutionary Fat-To-Fuel Plant

Danbury, Connecticut, has become the first city in the world to develop and build a facility that converts fats, oil, and grease, also known as FOG, into biodiesel fuel. This Grease to Diesel Plant is able to convert everyday restaurant kitchen grease waste into 220,000 gallons of high-quality biodiesel annually.

In April 2021, construction began at the site where the John Oliver Memorial Sewer Plant is located at 53 Newtown Road and was price-tagged at $5.5 million. According to Hearst Connecticut Media, the city's engineer and public works director, Antonio Iadarola, partnered with REA Resource Recovery Systems and UConn professor emeritus Richard Parnas.

According to cthousegop.com, fats, oil, and grease (FOG) are pumped into the plant, captured, and converted in an automated and continuous-flow system from kitchen grease pits across the greater Danbury area. According to Danbury Mayor Dean Esposito's FB Page, "The Grease to Biodiesel project will generate nearly 282,000 gallons of renewable fuel per year of which 222,000 will be B100 biodiesel fuel and 60,000 gallons will be boiler fuel, and will gain an estimated net income of $1.3 million per year for the City.
