When the Milan Expo opens next year, the centerpiece building will be a masterpiece of sustainable engineering. Designed around the idea of an urban forest, the new Palazzo Italia will generate its own electricity, and will be clad in materials specifically designed to clean the surrounding air. The designers, Nemesi & Partners, are using photocatalytic cement - basically, concrete that's been mixed with titanium oxide. When the building material comes into contact with ultraviolet light, the titanium oxide reacts with nitrogen dioxide in the air, converting the pollutant to a salt that can easily be washed away. The building will open in time for the Expo's launch next May, and we're already planning to book a trip over so that we can spend a day sniffing the air next to the building.
All this hate for the automobile and yet nobody seems to pay attention to the much worse culprits!
Madrid installing nitrogen-oxide capturing asphalt Posted Aug 12th 2008 at 4:03PM by Xavier Navarro Filed under: Etc., European Union Cities get some face lifts during summer months, when traffic is lower and most of its dwellers escape for vacations. Such is the case of Spain's capital city Madrid, which is renewing some of the asphalt on its streets with a bituminous mix called noxer that includes titanium oxide. This substance is claimed to capture the nitrogen oxides (NOx) at diesel pumps and catalyzes and stores the resulting less-polluting oxides until they're washed away by rainwater. It uses solar radiation to work and Madrid city council claims that it can capture up to 90 percent of these oxides on a sunny day. Additionally, the city is installing asphalt which used recycled tires on one of the city's main entries to reduce noise pollution.
