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).

Cement manufacturing is a source of greenhouse gas emissions. Concrete is the most common construction material used in the world. Cement is the principal ingredient in concrete. Producing one tonne of cement results in the emission of approximately one tonne of CO2,besides CO2, both cement and concrete production generate considerable quantities of air-pollutant emissions.

Making cement means making pollution, in the form of carbon dioxide emissions. Cement plants account for 5 percent of global emissions of carbon dioxide, the main cause of global warming. Cement has no viable recycling potential; each new road, each new building needs new cement.

Cement has a huge environment burden. Red-hot kilns used to make cement (a primary ingredient of concrete) emit 5 percent of the world’s man made carbon dioxide. Which is main pollutant for global warming and climate change. Cement can absorb this green house gas from the air and it can help a lot to reduce CO2 level into the air.
