Smog-Eating Buildings Clean the Air
Breakthrough construction technology by Millennium Chemicals of Britain may help to create buildings that actually absorb pollution. Promising pilot projects raise the near-future prospect of “smog-eating” homes and offices that remain unstained by fumes and even clean up the air around them. Project consultant Roy Colvile, senior lecturer in air quality management at Imperial College London, says “there is good reason to believe this could have a measurable effect.”
Applications spray a coating of titanium dioxide (also used as a toothpaste whitener) on existing surfaces or incorporate this mineral in manufacture of plastics, fabrics and ceramic tiles. Product trials along two London streets have attracted interest and support by the European Union.
