These Boeri-Designed Vertical Forests Are Helping Milan To Breathe
to find ways to help alleviate the problems and clean the air, but this approach is one of the most radical. In Milan, Italy the Italian architect Stefano Boeri devised a way to use the natural power of trees and plants to combat the pollution faced by the inner city. Trees and plants absorb carbon dioxide and emit oxygen, as well as acting as a filter for fine dust particles, making them a perfect resource for air purification. Taking this concept to the next level, in the Porta Nuova Isola area Boeri created two high-rise apartment blocks that are adorned with a massive number of trees and plants — 11,000 plants, 5,000 shrubs, 300 small trees, and 500 medium to large trees. In combination, the two towers have the capacity to convert around 44,000 pounds of carbon dioxide into oxygen annually.
