Air-filtering moss wall installed in Kolosy Square, Budapest
An air-filtering panel made out of moss was installed in Kolosy Square, a busy junction in northern Budapest, on Thursday.
The moss panel has the same air-purifying effect as 275 regular trees and will be in place for the next six months. It continuously measures its own efficiency and displays the data for public view.
Economy Minister Mihály Varga, who represents the area’s two districts, said at the unveiling ceremony that the 2nd and 3rd district governments had been at the forefront of implementing green projects in Budapest.
The local districts are renting the moss wall from Germany’s Green City Solutions for 20,000 euros.
