Environmental Product Declaration STEICO – wood fibre insulation
3.4 Cut-off criteria
No known material or energy flows were ignored, not
even those below the 1 % limit. The total amount of
ignored input flows is thus definitely below 5 % of the
energy and mass applied.
3.5 Background data
All background data come from the database /GaBi
Professional 6 Version 6.4120/ and /ecoinvent 2.2/.
3.6 Data quality
The data were collected at the production location in
the period 2013/14. The data obtained were validated
on a mass basis and according to plausibility
criteria. With the exception of 2 data sets, all
background data were taken from the database GaBi
Professional (6.108), which was last updated in 2013
The provision of forest wood was taken from a 2008
publication which is essentially based on information
from 1994 to 1997.
3.7 Period under review
The data were recorded for the period 01.07.2013 to
30.06.2014. All production data collected thus refer to
a production duration of 12 months.
3.8 Allocation
No co-product allocations occur in the entire modelling
process.
Credits from the thermal utilisation of production waste
are taken into account in Module A3.
3.9 Comparability
Basically, a comparison or an evaluation of EPD data
is only possible if all the data sets to be compared
were created according to /EN 15804/ and the building
context, respectively the product-specific
characteristics of performance, are taken into account.
4. LCA: Scenarios and additional technical information
End of Life (C2-C4)
After demolition of the building, it is assumed for waste
wood removed from it that it is initially transported
across a distance of 20 km to the next user (C2) where
it is crushed and sorted (C3). Waste wood is recycled
(D) and not disposed of. No expenses are therefore
incurred in Module C4.

Re-use, recovery and recycling potential (D),
relevant scenario information
The product is recycled in the form of waste wood in
the same composition as the declared unit at the end-
of-life stage. Thermal recovery in a bio-mass power
station with an overall degree of efficiency of 35% and
electrical efficiency of 23% is assumed, whereby
incineration of 1 tonne wood (atro) (at 18% wood
moisture content) generates approx. 1231 kWh
electricity and 2313 MJ useful heat. The exported
energy substitutes fuels from fossil sources, whereby it
is alleged that the thermal energy is generated from
natural gas and the substituted electricity complies with
the German power mix for 2009.
