The new waste-to-energy plant in Vantaa is dressed to impress



The most important construction materials of the waste-to-energy plant are concrete and steel. Steel structures in the frame and stairwells were supplied by Normek Oy, a company with ample experience on demanding building projects. Paints and coatings were supplied by Tikkurila Oyj.

Vantaa Energy is building a new waste-to-energy plant meeting even the most stringent environmental requirements. But as the plant will be constructed on a very public place at the junction of two highly-trafficked roads, there are requirements concerning the urban landscape to be considered as well.

The overall design of the waste-to-energy plant was the responsibility of Pöyry Finland Oy. Pöyry has been involved with the project since the environmental impact assessment (EIA) was completed in 2006. The construction began in summer 2011. Test runs started in March, and the plant will be fully operational in September 2014.

Concrete and steel

The most important construction materials of the waste-to-energy plant are concrete and steel. Steel structures in the frame and stairwells were supplied by Normek Oy, a company with ample experience on demanding building projects. Paints and coatings were supplied by Tikkurila Oyj.

– As the painting of the structures was completed at the workshop, only touching up had to be done onsite at the time of installation, says Juha Laarko, Purchasing Manager at Normek.
The paint system consists of Temazinc 77, an epoxy paint that contains zinc dust, as a primer and Temacoat SPA 50, a two-component resin-modified epoxy paint as a topcoat.

A chimney worth a look

For the neighbours of the plant, the most tangible reminder of its existence is the 70-metre high chimney, supplied complete with painting by the Danish company VL Staal A/S in Kjersing, near Esbjerg. The chimney was be shipped to Vantaa in four parts. It is not particularly high, but it is thick: with its diameter of 5.3 metres, it is the largest chimney the factory has ever manufactured.

– The chimney is also special because of its colours, says Jens Gravesen, who sells Tikkurila industrial coatings in Denmark. The bottom part is golden (RAL E2 270-M), the middle part is grey (RAL 7011) and the top is electric blue (RAL E2 590-6).

The painting was done by the Danish Scan-Coat A/S with the following system: Temazinc 77 as a primer, Temabond ST 300, a two-component modified epoxy paint with low solvent content, as an intermediate coat and finally Temasolid SC 60, a two-component polyurea-based paint with anti-corrosive pigmentation as a topcoat.

No more landfill

With a floor area of 26,000 m2 and a volume of 470,000 m3, the waste-to-energy plant is an investment worth about EUR 300 million. The plant helps in mitigating climate change by reducing environmental impact and the amount of waste going to landfill.
