Green walls.- Installing “green walls” in the cities can cut pollution down by up to 30% as recommended by a new research developed in the United Kingdom.
The green walls consists in panels made with grass and plants which could be installed in the walls of buildings and bridges.
Researchers assure that these innovative “green walls” plus a higher number of trees, plants and green spaces in urban area will clean the air dramatically as they help to remove nitrogen dioxide (NO2) a chemical produced by pollution and harmful for humans.
The team of experts from the University of Birmingham in collaboration with the Lancaster University has published a report in the scientific magazine “Journal of Environmental Science and Technology” explaining their findings.
