This

  contains
  the
  usual
  steps
  within
  an
  LCA
  according

  aforementioned
 
methodology
 of
  the
  tool,
  including
 goal
  and

  life

The
 goal
 of
  this
 LCA
  is
  to
 explore
 the
 STB’s
 overall
 potential
 environmental
  impact
  in
 order
 to
 
contribute
  to
  Teracom
  Group’s
  further
  sustainable
  work.
  The
  result
  will
  be
  used
  to
 
communicate
  this
  development
  within
  the
  company
  and
  form
  a
  base
  for
  further
 
recommendations
 regarding
 future
 purchase
 of
 products.

The
  chosen
  product,
  which
  also
  represents
  the
  functional
  unit
  for
  the
  LCA,
  is
  as
  previously
 
mentioned
 one
  (1)
  STB
  from
  Sagemcom
 with
 model
  number
  RTI90
  320HD.
  The
  product
  itself
 
including
 supplied
 accessories
 such
 as
 cables,
 remote
 control
 with
 batteries,
 the
 manual
 and
 the
 
package
 are
 all
 included.
 The
 total
 weight
 of
 the
 packages
 delivered
 to
 final
 customers
 is
 1.776
 
kg.
  The
  lifetime
  of
  the
  product
  is
  assumed
  to
  be
  5
  years.

F;8;=.2B-,(+./%:$)104(-.
The
 life
 cycle
 of
 the
 chosen
 products
 begins
 with
 resource
 extraction
 from
 nature,
 to
 obtain
 all
 
materials
 needed
 for
 the
 production.
 The
 resource
 extraction
 can
 be
 described
 as
 the
 cradle
 of
 
the
 product
 and
 will
 only
 occur
 at
 the
 very
 beginning.
 The
 life
 cycle
 ends
 when
 the
 materials
 are
 
returned
  to
  nature
  as
  emissions
  or
  end
  up
  at
  landfills.
  Since
  emissions
  will
  occur
  during
  the
 
whole
 life
 cycle,
 it
 is
 harder
 to
 specify
 the
 grave.
 The
 system
 boundaries
 are
 further
 illustrated
 in
 
a
 flowchart
 (figure
 6)
 under
 4.2.2
 Flowchart
 of
 the
 life
 cycle.
 

 
Different
 geographical
 system
 boundaries
 will
 affect
 different
 phases
 of
 the
 product’s
 life
 cycle.
 
The
  resource
  extraction
  will
  most
  likely
  occur
  all
  over
  the
  world
  making
  boundaries
  hard
  to
 
predict.
  Most
  of
  the
  components
  manufacturer
  are
  however
  limited
  to
  China.
  The
  assembly
 
process
 of
  those
 components
  takes
 place
  in
 Tunisia
 and
  the
 products
 are
 sold
 only
 within
  the
 
Swedish
 market.
 The
 transports
 between
 these
 locations
 affect
 globally.
 

 
The
  time
  horizon
  stretches
  from
  use
  of
  raw
  materials
  (involving
  resource
  extraction)
  to
  the
 
waste
 scenario,
 including
 production
 and
 use.
 The
 data
 and
 the
 situation
 will
 represent
 current
 
time
 meaning
 that
 future
 development
 and
 changes
 will
 not
 be
 considered.
 

 
The
  technical
  system
  consists
  of
  all
  the
  human
  processes,
  from
  when
  natural
  resources
  are
 
extracted
 until
 these
 are
 released
 back
 as
 emissions
 to
 nature
 or
 as
 waste
 to
 landfill.
 The
 LCA
 is
 
limited
  by
  investigating
  only
  the
  resource
  extraction
  and
  assembly
  process
  of
  the
  production
 
phase.
 This
 involves
 imported
 components
 including
 all
 materials
 and
 energy
 (electricity),
 water
 
and
 nitrogen
 used
 during
 the
 assembly
 of
 these.
 Due
 to
 difficulties
 in
 examining
 sub
 suppliers,
 
the
 processes
 of
 components
 manufacturing
 and
 systems
 linked
 with
 these
 are
 not
 included.
 

 
Boundaries
  regarding
  transports
  (figure
  3,
 where
  truck
  transports
  are
  indicated
  by
  green
  and
 
ship
  transports
  are
  indicated
  by
  blue)
  within
  the
  life
  cycle
  include
  transports
  from
  Chinese
 
components
 manufacturers
 throughout
 the
 chain,
 ending
 at
 the
 local
 postal
 offices
 in
 Sweden.
 
The
 components
 are
 transported
  from
 the
  factories
  to
 a
 Chinese
 harbour
 by
 truck
  (right

 in

 From
 there
 the
 parts
 are
 shipped

factory
 in
 Tunisia.
 The
 final
 products
 are
 then
 transported
 to
 France
 by
 ship
 (blue
 line
 in
 figure
 
3)
  over
  the
  Mediterranean
  Sea.
 
  Trucks
  are
  used
  to
  transport
  the
  products
  through
  Europe
 
(green
 line
 in
 figure
 3)
 to
 Boxer’s
 Swedish
 warehouse
 located
 in
 Kalmar.
 (Tremblay,
 2012b)
 The
 
products
 are
 distributed
 to
 the
  local
 postal
 offices
 by
 truck
  (left
 hand
 green
 circle
  in
  figure
 3).
 
Additional
 transports
 such
 as
 from
 the
 postal
 offices
 to
 final
 customer
 and
 to
 recycling
 centres
 
etc.
 will
 not
 be
 included
 due
 to
 the
 relative
 short
 distances
 and
 lack
 of
 statistics
 regarding
 these
 
kinds
 of
  transports.
  Furthermore,
  transports
  of
  disposed
 products
  to
  recycling
 plants,
  landfills
 
etc.
 was
 excluded
 for
 the
 same
 reason.
 Distances
 used
 for
 the
 LCA
 can
 be
 found
 in
 appendix
 I.

The
 study
 is
 further
 limited
 to
 the
 Swedish
 market,
 including
 statistics
 and
 other
 data
 regarding
 
households,
  energy
 mix,
 waste
  scenario
 etc.
  The
 examined
 STB
  is
  sold
 not
 only
 by
 Boxer,
 but
 
also
 by
 other
 retailers,
 both
 in
 shops
 and
 online.
 These
 will
 not
 be
 included
 in
 the
 LCA.
 Capital
 
goods
 such
 as
 factory,
 office
 buildings
 and
 machinery
 used
 to
 produce
 the
 product
 will
 not
 be
 
included
  in
  this
  LCA
 since
  these
  types
 of
  tools
  last
  for,
 and
 produce
  far
 more
  than
 1
 STB.
 The
 
personnel
 and
 their
 potential
  impact
 on
 the
  life
 cycle
  for
 all
  involved
 companies
 and
  factories
 
will
 not
 be
 taken
 into
 account.
 Other
 related
 services
 such
 as
 maintenance
 and
 reparation
 of
 the
 
products
 will
 also
 be
 excluded.

  assembly,
  transports
  and
  the
  use
  of
  the
  STB.
  For
  the

  including
 
areas
  such
  as
  processing
  of
