In some cities in UK, lush gardens growing on building walls
have given new life to the concrete jungle of the metro. These “vertical
gardens” provide not only aesthetic qualities, but also actual
benefits, including cleaner air.
British company Biotecture builds and designs such green walls. With
the use of a "modular hydroponic system," plants grow without soil
on building walls and receive nutrients through water pipes. The system can
be made to fit any building wall.
Biotecture creative director, Mark Laurence, says that vertical
gardens can also improve air quality. One of the company’s projects is the
200-square meter wall on the side of Edgware Road Underground Station in
London. The wall is near one of the UK's grimiest city roads.
According to Laurence, researchers from London’s Imperial college
regularly take and wash samples of the leaves on the wall, to see how much
pollution particles the leaves
have collected.
In areas with narrow roads, Laurence says vertical gardens would do
better than trees in cleaning air. In these places, air usually moves around
building walls. With vertical gardens, air can be filtered before it
reaches the streets below where people breathe it.
Additionally, vertical gardens may someday be used to grow
vegetables in less polluted areas for extra food supply. Biotecture
successfully grew 45 kinds of vegetables in an experiment.
Many people are even building their own vertical gardens, adds
Laurence. He believes their popularity is due to people wanting more
environment-friendly services and designs in the city.
