Anicet Mbida gives us every morning what is best in innovation. This Friday, he is interested in an invention that could improve the air quality in tunnels.

It is the concrete itself that will be able to eat the pollution of the exhaust pipes. It works a bit like the catalytic converter of cars. It will break down polluting particles (nitrogen oxides, sulfur oxides and other junk that come out of exhaust pipes), and it will transform them into harmless substances. It could also be used as a building material whether for walls, bridges or sidewalks.
