Evaluation of the performance of vegetative buffers for emission reduction of particulate matter from poultry facilities Adderley, Christopher; Christen, Andreas
Abstract
Emissions of particulate matter from poultry facilities can impact local resources, animal and human health, and can be a potential pathway for the transmission of diseases. This report determines the effectiveness of various vegetative buffers layouts as a potential measure reducing particulate matter emissions leaving poultry facilities. Vegetative buffers modify the airflow and filter the air flowing through them, which can enhance the deposition of particulate matter on leaves and ground, and redistribute zones of major deposition. The report summarizes five case studies of poultry facilities in the Lower Fraser Valley, BC, Canada. It demonstrates that appropriate choice of vegetative buffer layout (composition and placement) can affect overall emissions from poultry facilities and hence reduce deposition on neighboring properties. The use of effective buffer layouts allows part of the emitted particulate matter to be intercepted before leaving the property. The simulations predict that the fraction of total PM10 emissions intercepted by the buffer ranges between 0.62 to 4.38%. In relative terms, total deposition on the property can be increased between 10.81% and 29.37% with effective buffer configurations. Deposition on neighboring properties is predicted to be lowered between -‐2.05 and -‐7.62%. In conditions where the buffer is placed directly in front of the source fans and wind directing particulate matter directly into the buffer, highest interception was achieved (filter effect). In other cases, buffers disrupt wind patterns modifying air flows and hence affect spatial deposition patterns (deflection effect). Layouts with corner structures were more effective, as were layouts including double rows and full enclosure around the emission sources. Although these simulations show that buffers can be effective to control (reduce) deposition on selected neighboring properties of concern (up to 7.62% reduction), their impact is limited in terms of overall emission reduction to the environment as overall reduction simulated was less than 3.12%.

Emissions
of
particulate
matter
from
poultry
facilities
can
impact
local
resources,
animal
and
human
health,
and
can
be
a
potential
pathway
for
the
transmission
of
diseases.
This
report
determines
the
effectiveness
of
various
vegetative
buffers
layouts
as
a
potential
measure
reducing
particulate
matter
emissions
leaving
poultry
facilities.
Vegetative
buffers
modify
the
airflow
and
filter
the
air
flowing
through
them,
which
can
enhance
the
deposition
of
particulate
matter
on
leaves
and
ground,
and
redistribute
zones
of
major
deposition.
The
report
summarizes
five
case
studies
of
poultry
facilities
in
the
Lower
Fraser
Valley,
BC,
Canada.
It
demonstrates
that
appropriate
choice
of
vegetative
buffer
layout
(composition
and
placement)
can
affect
overall
emissions
from
poultry
facilities
and
hence
reduce
deposition
on
neighboring
properties.
The
use
of
effective
buffer
layouts
allows
part
of
the
emitted
particulate
matter
to
be
intercepted
before
leaving
the
property.
The
simulations
predict
that
the
fraction
of
total
PM10
emissions
intercepted
by
the
buffer
ranges
between
0.62
to
4.38%.
In
relative
terms,
total
deposition
on
the
property
can
be
increased
between
10.81%
and
29.37%
with
effective
buffer
configurations.
Deposition
on
neighboring
properties
is
predicted
to
be
lowered
between
-‐2.05
and
-‐7.62%.
In
conditions
where
the
buffer
is
placed
directly
in
front
of
the
source
fans
and
wind
directing
particulate
matter
directly
into
the
buffer,
highest
interception
was
achieved
(filter
effect).
In
other
cases,
buffers
disrupt
wind
patterns
modifying
air
flows
and
hence
affect
spatial
deposition
patterns
(deflection
effect).
Layouts
with
corner
structures
were
more
effective,
as
were
layouts
including
double
rows
and
full
enclosure
around
the
emission
sources.
Although
these
simulations
show
that
buffers
can
be
effective
to
control
(reduce)
deposition
on
selected
neighboring
properties
of
concern
(up
to
7.62%
reduction),
their
impact
is
limited
in
terms
of
overall
emission
reduction
to
the
environment
as
overall
reduction
simulated
was
less
than
3.12%.
