Fighting pollution with… concrete?Posted: August 8, 2008
A town in Holland will be trialling a novel way of reducing atmospheric pollutants when it lays down a road of pollution-eating bricks.
The bricks contain a titanium-dioxide compound that binds up atmospheric nitrogen oxide into water soluble nitrates that will be washed away in the next rain storm. Clever.
Tests next year will compare air in the area of the town paved with these bricks to the areas paved with regular building materials. It will be interesting to see if the practical outcome lives up to the theory.
