Another Step Toward Clean Air

March 25, 2008

In the March 31, 2008 issue of Business Week Magazine I read about a new "recipe" for concrete. I quote from the article.

"Concrete is about to start helping in the fight against air pollution, thanks to a new recipe spiked with titanium dioxide, a compound that becomes chemically active in sunlight. Originally concocted for Italy's Italcementi for its bright, white , self cleaning features, the product, called TX active cement, also neutralizes air pollutants such as benzene, carbon monoxide, nitrogen oxide and others.In the U.S. ...the first application may be to improve air quality at schools near highways. Working with the school districts in Los Angeles and elsewhere, architectural firm Fieldoffice has designed exotic-looking barriers to keep road smog and noise away from areas where kids live, study and play."

With the concern nowadays about improving our environment, it is encouraging to know that industries are working to find innovative solutions.
