Aktor Awards Contract to Cambi

10TH June 2014

The Greek construction company Aktor has awarded Cambi a contract for the installation of Cambi’s Thermal Hydrolysis system (CambiTHP™) at Psyttalia Island Wastewater Treatment Works in Athens. Serving 5.6 million people, Psyttalia is the largest wastewater treatment plant in Greece and one of the largest in Europe. When operational in 2015 the Cambi system will treat about 50 dry tonnes of biological sludge per day.

Aktor, which is in charge of the operation and maintenance of the Psyttalia Wastewater Treatment Plant, was looking to significantly reduce the energy footprint and based their final choice for the Cambi pre-treatment system on multiple considerations.


Ioannis Margiolos, Aktor’s Water Business Unit Director, states: “the most important reasons for choosing the Cambi process is that it will drastically improve the dewatering efficiency, reduce the energy need for the existing drying plants and increase the gas production from biological sludge. Overall it will result in a strong reduction of energy consumption and reduced disposal costs.”

Cambi ́s chief executive officer Per Lillebø congratulates Aktor with the move to upgrade the Psyttalia Island Wastewater Treatment Plant with the CambiTHP system, providing the best environmental and economic benefit for the people of Athens.

Aktor is the largest construction company in Greece, member of Ellaktor Group, an international construction company. It is a leader in the field of liquid and solid waste disposal projects throughout Greece and provides integrated services from the conception, design and construction phases through to the operation of these plants.

Cambi is a world-leading provider of technologies for conversion of biodegradable material to renewable energy and valuable bio-fertilizer resources, based on its patented thermal hydrolysis process (CambiTHP).
