Alcoa Inc (AA.N) said it will start selling an aluminum building panel that removes smog from the air using a chemical commonly found in automobile paint.
Using a proprietary process developed with Japan's Toto (5332.T), Alcoa said it turns fine grounds of titanium dioxide into a clear paste then applies it the surface of aluminum.
The titanium dioxide interacts with sunlight and breaks pollution in the surrounding air into carbon dioxide particles that are washed away by rainwater, Alcoa said.
