Cambi awarded its second THP contract in Greece

Asker, 8 April 2022, 09:33 CET

Cambi has been awarded a contract to supply a second B6 thermal hydrolysis system to the Psyttalia wastewater treatment plant in Athens, Greece.

The Psyttalia plant is the main wastewater treatment facility of the Greater Athens area. It is also one of the largest in Europe, with a capacity to serve a population equivalent of 5.6 million. Cambi's first thermal hydrolysis unit in the country has been in operation at the site since 2015 and was chosen to improve sludge dewatering efficiency, increase biogas production, and reduce the energy needed for biosolids drying. 

"The Psyttalia plant contributes significantly to the protection of the ecosystem of Athens' metropolitan area, and we are excited to increase our contribution to our client's effort in this regard. The Cambi unit already on site has helped enhance the production of biogas, which helps cover a significant portion of the plant's energy needs. Adding a second train will further reduce energy costs. The plant is also a great example of the benefits of thermal hydrolysis for locations that thermally process biosolids," remarked Cambi Group CEO Eirik Fadnes.

The contract was awarded by the Joint Venture ”AKTOR SA - AVAX SA – ERGOTEM SA”. The thermal hydrolysis unit is set to be delivered in summer 2023.
