Pollution-Eating Concrete to Save Your Lungs

by Rosie Spinks

July 10, 2010
Researchers in the Netherlands have recently tested a special type of concrete that has the potential to absorb nitrogen oxides, which are a much more potent greenhouse gas than carbon dioxide. If implemented, this concrete could cut down on the the smog and acid rain caused by car exhaust. As Treehugger reports:

We already knew it worked in the lab, but this was a real-world test and the results are pretty impressive: a 25 to 45% reduction in oxides of nitrogen (NOx) over the special roads. This could mean that someday our roads and other concrete structures could be used to clean up the air.

This seems like a practical idea, though it is somewhat of a secondary fix that doesn't attack the root causes of pollution. However, if city dwellers decide to walk, rather than drive, on this NOx-hungry concrete, then maybe we're on to something.
