Could the green wall filter microplastics from urban runoff?
InnoGreen is currently examining how effectively microplastics can be filtered from urban runoff by directing the runoff water through a green wall. For research purposes a modular green wall was built in Konala, Helsinki. The runoff water from Kehä 1 ring road is directed into the green wall. The study is one of the Speedy Experiments of the Baltic Sea Challenge.
