“Bringing a reusable coffee cup with you should become normal,” says NS spokesman Willemijn Weinands. By 2040, all stations must be zero-waste, i.e. no residual waste and all materials must be recycled. In order to reduce waste, travelers can also return deposit bottles at the central stations of Utrecht, Amsterdam, Rotterdam, The Hague and Eindhoven from September. The railway operator expects to collect ten million bottles a year with this.
