Cambi awarded engineering study for a THP plant in Dunkirk France

Asker, Norway, 19 January 2024, 13:43 CET

Cambi is pleased to announce a contract with Suez for an engineering study for a thermal hydrolysis process (THP) system at the Grande Synthe wastewater treatment plant in Dunkirk, France.

The Dunkirk Urban Community and utility operator company Suez are upgrading the Grande Synthe plant with a sludge digestion facility that will treat both the indigenous sludge and sludge from several smaller sites while reducing associated costs and increasing biogas production.

“Cambi is pleased to continue our longstanding global collaboration with Suez, for the first time with a potential project in France. We look forward to working together in the coming months to describe in detail how one of our modular THP systems can integrate and transform how wastewater solids are treated in Dunkirk”, said Lars Petter Traa, Cambi acting CEO.

The engineering study follows a master plan that identified thermal hydrolysis as an effective way to pre-treat secondary solids before anaerobic digestion at the Grande Synthe site.

The study will be delivered within the first half of 2024 and is an important step towards an equipment delivery contract.
