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
