Zaloa Azkorra, an agricultural engineer of the UPV/EHU-University of the Basque Country, is conducting research at the University School of Mining and Public Works Engineering into the benefits provided by green walls. The researcher has concluded that walls comprising plants offer great potential for absorbing noise and could be used as acoustic insulation. Right now, she is conducting thermal studies on them. The researcher believes they could be beneficial in the future to offer a greener image of towns and cities, to improve the life quality of citizens, to save energy, to increase biodiversity, to control rainwater, to lessen town/city noise and to minimize waste and pollution.
