Air cleansing concrete tested in Copenhagen

First publishedon www.AggBusiness.com
The Danish Technological Institute (Teknologisk Institut) says it has developed a concrete material with air cleaning properties.

The concrete employs a modified form of titanium dioxide which allows for the removal of harmful mono-nitrogen oxides (NOx) from the air with the aid of light in the visible spectrum.

Previous similar technology is said to have required light in the UV spectrum.

The new material is currently being tested in the pavement on the Fælledvej Street in Copenhagen. Two other demonstration projects will also be undertaken.

The project is part of the EU research project Light2CAT.

Morten Kabell, Mayor of Technical and Environmental Affairs in Copenhagen, says that a reduction in emissions from traffic is the most important means of reducing air pollution in the Danish capital.
