Enrico Borgarello is head of Research and Development at Italcementi, has developed a cement that can ‘eat’ pollution. The way it works is a substance called TX Active is added to the cement so that “When light sines on TX, the material becomes active and neutralizes surrounding pollutants.” After 10 years and $10 million dollars spent developing the product, Italcementi test results indicate that TX can reduce local air pollutants from 20% to 70%, depending on sunlight levels and wind. Borgarello estimates that if you could cover 15% of a concrete jungle like Milan and you would cut pollution in half. The company is eyeing developing countries like India and China where annual cement demand in China is expected to rise above 1 billion tons this year. The first building to use the cement was the 2003 Dives in Misericordia church in Rome by architect Richard Meier.

Well, it’s here. The sixth annual U.S. Green Building Council (USGBC) Greenbuild Expo. The Expo is the nation’s, and possibly the world’s, largest gathering of individuals centered exclusively on green building. Since the Expo events started in 2002 they have grown dramatically in popularity and this week some 20,000 building professionals will merge on the new West Building in Chicago’s McCormick Place to delve into the greening of our built environment. Former U.S. President Bill Clinton will be the keynote speaker this Wednesday morning, most likely discussing his foundation’s plan to spend $5 billion renovating buildings to improve their efficiency and resource use. Cities that have adopted major environmental initiatives will also be presenting on the agenda such as Albuquerque’s Martin Chavez and Austin’s Will Wynn.
