Structures that literally eat smog: scientists and architects are devising air purifiers as big as buildings.
According to a 2012 World Health Organization report, air pollution is linked to more deaths than diabetes, accidents and AIDS together, causing one in eight deaths in the world.
This is why some architects are creating smog-eating buildings, whose façades are covered with titanium dioxide (TiO2), a powerful catalyst that can break down air borne pollutants into environmentally harmless products.
One such building is the Manuel Gea González Hospital in Mexico City, one of the most polluted cities in the planet.Manuel Gea González Hospital smog-cleaning facade
The façade is supposed to neutralize the polluting effects from produced by 1,000 vehicles every day.
Another building of this kind, currently under construction, is Palazzo Italia in Milan, Italy.

Scheduled to launch at the 2015 Milan Expo, this six-story pavillion will have a façade made of air-purifying, “biodynamic” cement.
Innovation has never looked better!
