Less smog in Wola

30 October 2018

POLAND The photocatalytic concrete used in the paving of Genereation Park in Warsaw’s Wola district can reduce smog levels by around 30 pct.

Skanska has completed more than three months of testing at the Daszyńskiego roundabout, which showed the effectiveness of the material in the fight against smog. The paving stones have a layer around a centimetre thick, which decomposes nitrogen compound particles. The air was monitores at the site for 3.5 months. “Our station tested the air quality at a height of 180 cm above the 350 sqm pavement. For comparison, we also examined the level of pollution in an area where there was no ‘green concrete’. It turned out that the concentration of nitrogen dioxide above the self-cleaning pavement was on average 30 pct lower than compared to the control. The best results were recorded 50 cm above the pavement, which is especially important for the health of young children,” says Anna Tryfon, the innovation manager at Skanska. A photocatalytic concrete square the size of a football field is eventually be built around the Generation Park.

In the project Skanska was partnered by Górażdże Cement, the Institute of Geophysics at the Polish Academy of Sciences, the Faculty of Civil Engineering at the Warsaw University of Technology and the Faculty of Geology of the University of Warsaw.
