💚 New concrete creates living moss walls that absorb pollution
Moss in cities can absorb pollution and clean the air. But it is difficult to grow in the metropolitan areas. Spanish researchers have now developed a concrete in which the moss can grow.

Ordinarily, moss can't grow directly on the walls of buildings. They need an organic layer, like wooden pallets, to grow on. But now Spanish scientists have developed a concrete on which the moss can grow directly.
The concrete consists of three layers, which allow the plants to get enough water and the opportunity to grow firmly in the wall.
Just like the artificial tree we wrote about last month , this moss can absorb pollution and clean the air.
This new concrete is now being tested at the University of Ghent in Belgium and the Universitat Politècnica de Catalunya in Spain.
