Dutch town to pave road with air-purifying bricks
The road to Hengelo is paved with good inventions. The Dutch town [map, wiki, official] is paving a local road with green bricks containing “a titanium dioxide-based additive” that “binds the nitrogren oxide particles emitted by car exhausts and turns them into harmless nitrates” when sunlight is added to the mix.
This is the first test outside of University of Twente laboratories and I’m anxious to hear about the results. I’d like to see more small towns in the United States welcome experiments such as this one.
The University of Twente’s press release and a picture of the bricks may be found here.
