The
transition
from
waste
management
to
resource
and
recycling
management,
along
with

increasing
price
pressure
and
resource
scarcity
has
required
improved
quality
and
efficiency
of

resource
uses.
This
applies
to
businesses
from
commercial
and
municipal
waste
management,
as

well
as
industry,
trade
and
service
enterprises
with
in-­‐house
waste
disposal
tasks.
The
Port
of

Koper
collects
and
separates
waste
generated
by
port
activities,
including
waste
wood.
This
is

crucial
for
achieving
sustainable
use
of
natural
resources.
They
collect
between
1,500
t
and
2,000

t
of
waste
wood,
mostly
in
the
form
of
sawdust,
shavings,
wood
chips
and
wooden
packaging.

Only
approximately
2%
of
collected
waste
wood
is
not
useable.

The
aim
of
the
presented
research
was
to
examine
the
environmental
impacts
of
two
possible

scenarios
for
the
treatment
of
waste
wood.
First,
processing
of
waste
wood
into
particleboards
to

extend
its
life
cycle,
and
second,
production
of
wooden
pellets.

to

the

of
the
product

made
from
raw
materials
in
comparison
to
the
product
made
from

with
