The University of Twente in the Netherlands has developed a new concrete type — with a titanium dioxide-based additive — that binds the nitrogen oxide particles emitted by car exhausts and turns them into harmless nitrates when under sunlight.
“With one rain shower everything is washed clean,” the institution said in a statement.
Concrete pavers based on this technology are now being put to the test in Hengelo in the eastern Dutch province of Overijssel.
One half of a road under reconstruction is being paved with the new, green bricks, and the other half with the ordinary variety.
