Year after year Scotscape endeavour to create and
innovate. In order to do this effectively all aspects of
the green industry are observed. Air quality is one of
those areas that Scotscape is keen to address. As our
living wall and ’Smart’ greening systems continue to
populate the urban landscape we want to ensure
that health and well being become an integral part of
our future design, thereby helping to breathe new
life into our cityscapes.
The 25m2 woodland living wall at our HQ (left) has
been developed as a natural progression to our
existing living wall system and has been
predominantly planted with shrub and tree species
that have the ability to trap pollutant particulates
from the air (mostly larger pm10 dust particulates
but also smaller pm2.5 such as diesel exhaust fumes)
Foliage with traits such as a waxy surface or dense
hair on the surface have a great ability to physically
trap these pollutants. The foliage of a typical ivy can
absorb high concentrations of pollutants such as
formaldehyde and xylene with no ill effects to the
plants.
On page 2 we list a selection of our plant choices and
their known benefits along with our planting plan.

Case Study 2017
Our standard 1m2 living wall module contains 49 x 1litre
pockets. Our new woodland system 1m2 module con-
tains 15 pockets x 3litres which greatly increases the
future plant size allowing for a higher concentration
pollutants to be trapped.
Beneficial soil microbes also play their part in helping to
remove VOC’s from the air and with our new larger
pockets a greater amount of soil is exposed to the ele-
ments, passing
pollutants can be-
come trapped help-
ing to filter
pollutants, most
especially larger
particles such as

Most Effective Pollutant Trapping Species
Pinus mugo/Pinus sylvestris
The density and structure of a
pine trees needles traps
pollutant particulates– waxy
needles allow for pollutants to
adhere to the surface where the
tree can break it down. They are
evergreen and can provide more
surface area than a broadleaf
tree. The structure allows for air
to pass through increasing the
pollutant trapping efficacy
Stachy byzantina &
Bello grigio/ Geranium
macrorrhizum—The key
feature of these species is
the dense layer of hair the
leaf surface. As air passes
over the surface of the leaf
the particulates become
trapped.
Camelia japonica/Hedera
helix These species have a
waxy leaf surface, as
pollutants adhere to these
surfaces easily pollutants be-
come trapped. From previous
studies it has been shown that
hedera has the ability to trap
pollutant particulates pm2.5
(Sternberg et al.,2010) Hedera
is also a perfect species for
biodiversity, providing food
and nesting.
Arbutus unedo/Rhus
Not as effective as the
previous methods but
both hairy and rough
bark species such as
these help with the pro-
cess of physically trap-
ping particulates as air
moves through the
various lower and higher
points of the foliar strata
on a living wall
