After ages of construction work and trying to find one’s way through and around during the construction, Arnhem’ Central Station is being officially opened to the public this afternoon. It was designed by Amsterdam’s UNStudio who spent almost two decades working on this modern train and bus station with a heavy use of really big metal pillars and seriously twisted concrete. In fact, architect Ben van Berkel of UNStudio wanted to use even more concrete, but the city considered it too risky.
The concrete itself won the station the ‘Betonprijs 2015’ (‘Concrete Award 2015’), so it’s safe to say enough concrete was used to make a splash.

Hengelo, Overijssel looks to be taking a rather unique approach to cleaning the air, with it now testing out a new type of “air-purifying concrete” developed by the University of Twente that promises to soak up the nitrogen oxide particles emitted by car exhausts. This is done with the aid of a titanium dioxide-based additive which, with the help of some sunlight, binds with the nitrogen oxide particles and turns them into harmless nitrates, which can apparently just wash away with the next rain shower. Hengelo is not fully sold on the idea just yet, with it only paving half of a road now under construction with these “green bricks”, while the other half is getting paved with plain old concrete. They will then take some air measurements from each section early next year and decide whether to continue paving the town green or not.
