Doranova started a soil remediation project in Helsinki city center

4.1.2019 Antti Myllärinen

One of the most significant urban planning projects of Helsinki city area is the property of the Hanasaari power plant. The plant is situated in the heart of the city and was commissioned back in 1974. It uses coal as a fuel and produces 220 MW of electricity and 420 MW of heat for central heating system of Helsinki.

The plant will be dismantled next decade and the area will be converted to a residential area. The challenge for this conversion is that the soil underneath the plant is heavily contaminated and need to be remediated.

Doranova was one of the three companies that got an opportunity to pilot their remediation solutions in a European wide tender process.

Remediation with DoAct CORE and DoAct DIRECT

Doranova started the pilot phase by bringing purpose-built DoAct CORE remediation unit to the site in Autumn 2018. This CORE unit will be applied throughout the 12-month pilot phase. In addition, DoAct DIRECT system will be used next summer to treat the most contaminated hotspots.

Full-size project after the pilot phase

During the pilot phase the city of Helsinki evaluates the efficiency of different remediation methods. Therefore, the contractor for the actual full-size project will only be decided in late 2019.

– This kind of an approach is exactly the right one in project this big, says Perttu Mattila, the Head of Soil and Groundwater remediation. In this way the city can safeguard that taxpayers’ money is well-spent and the power plant area can be safely converted for residential use in the future, Mattila concludes.
