Southampton living walls absorb traffic pollution
A living wall has been installed on a roundabout as part of a new initiative.
The vertical planting is designed to help offset vehicle emissions at the Millbrook roundabout in Southampton.
The West Sussex-based Biotecture won a contract with Highways England as part of a £30m annual investment in innovation.
The plants in the walls draw in air and can remove the pollutants.
