6. LCA: Interpretation
Figure 1 illustrates the contribution of each life cycle
stage to the overall indicator results of the impact
assessment (impact from module A1A3 = 100 %) for
particleboard coated with melamineimpregnated
paper. The Figure illustrates that for the GWP, the
ODP and the ADP fossil, the benefits from the energy
recovery of coated particleboard are higher than the
impacts during the life cycle, notably the impacts from
production. For other impact categories, the benefits of
energy recovery lie between 2 % to 30 %, depending
on the impact category under consideration.
The global warming potential (GWP) is an indicator for
the contribution to climate change and is
quantified based on the emissions of gases that
absorb radiative forcing.
The production of the UF/MUF resins contribute about
45 % to the GWP (excluding biogenic carbon) caused
during production of uncoated particleboard. Further
contributions stem from the production of heat from
light fuel oil and natural gas (about 18 %) and from the
generation of electricity (about 10 %). Transport of raw
materials are responsible for about 9% of the GWP.
For particleboard coated with melamine impregnated
paper, 65 % of the GWP are caused during board
production, 35 % are associated with the production of
the melamine impregnated paper.
