Smog Eating Roof Tiles
October 3, 2011 by Robin Plaskoff Horton
A sustainable concrete roofing tile that reduces the formation of smog, BoralPure, winner of the Popular Mechanics 2011 Breakthrough Award announced today, is the only concrete tile roofing solution in the U.S. that mitigates air pollution.
The harmless byproduct accumulates on the roof and washes away in the rain. With no machinery or energy input other than sunlight, the air-cleansing tiles mitigate the same amount of nitrogen oxide (the major component of smog) produced by one car driving up to 10,800 miles.
