I have just read on a website that an Italian cement-making company have just created a new form of cement that will actually reduce the levels of pollution in big cities...... It is said to "kill" smog & pollution.
The cement has been named TX Active & is enhanced with titanium dioxide. The company claims that through a natural process called photocatalysis (occurs in sunlight), the titanium dioxide takes harmful chemicals from the air & turns them into harmless substances like water & nitrates. The cement is also self cleaning, and so any bi-products simply wash away with the rain. Italcementi (the cement company) believe that even if only 15% of buildings in a city were coated in TX Active, it would reduce pollution rates by upto 60%.

I am not convinced by these claims, however if it were to be true then it would be an incredible breakthrough in controlling pollution levels in large cities.
