Smog-eating buildings the solution to Beijing's smog?

Heavy smog is a growing problem in Beijing and 25 provinces in China. When even adding more trees and plants can't help China clean up its air, what sort of solution is out there?

A smog-eating building! Designed by Berlin's Elegant Embellishments, this innovative tile material on the Torre de Especialidades Tower outside a hospital in Mexico City mitigates smog by neutralizing exhaust emitted by hundreds of passing cars each day.

A layer of titanium dioxide, which is also found in sunblock and paint, is applied to the tiles on the building's beehive-shaped facade. When exposed to ultraviolet rays from the sun, titanium dioxide breaks down smog into safer chemicals, such as water and carbon dioxide.

The unique beehive shape also increases the surface area that can react with sunlight. According to designers, the smog-eating tiles best function best at parking lots, sky bridges and bus stations.
