Cement that Absorbs Pollution
If you’ve ever cycled on a busy road you’ll know how bad pollution can be. Inside of letting cyclists filter the pollution out of the air (via their lungs) the answer might be in cement.
This is what physorg had to say on the echnology:
Tests on a road near Milan showed TX Active cut the level of nitrogen dioxide and carbon monoxide by as much as 65 percent.
It functions via a chemical process called photocatalysis, whereby sunlight triggers a chemical reaction when titanium dioxide on the surface of the cement comes into contact with pollutants in the air. TX Active works most effectively in bright sunlight.
Italcementi said test results have been verified by independent bodies like the National Research Council.
This could make many a cyclists daily commute a lot more pleasant. Full article here (found via digg).
