In Warsaw, near the Daszyńskiego Roundabout, you can walk along the concrete pavement which cleans air pollution generated by exhaust fumes. This is possible due to a special mix of concrete, which breaks down harmful NOx molecules into neutral nitrogen.
How it is work?
This concrete have photocatalytic properties. With the help of the sun’s rays, this concrete can reduce harmful compounds from car exhausts (including nitrogen dioxide). These compounds are broken down into harmless substances, similar to those used for fertilizing plants which can then be deposited into the soil via precipitation. An additional advantage of the concrete is that it has self-cleaning properties.
Partners of the project: Skanska and Górażdże Cement S.A company – the producer of the concrete.
