3.2
System boundary
The Declaration complies with an EPD "from cradle toplant gate, with options". It includes the production
stage, i.e. from provision of the raw materials throughto production (cradle to gate, Modules A1 to A3),
Module A5, and parts of the end-of-life stage (Modules
C2 and C3). It also contains an analysis of thepotential benefits and burdens over and beyond the
product's entire life cycle (Module D).

A2. Module A3 includes the expenses associated with
manufacturing the product, such as the provision offuels, consumables and energy, as well as productpackaging.
Module A5 exclusively covers the disposal of productpackaging which includes the disposal of biogenic
carbon and primary energy (PERM and PENRM).
Module C2 considers transport to the disposal
company and Module C3 is concerned with preparing
and sorting waste wood. Due to a lack of data, theconservative assumption was made that the material iscrushed – as is the case for waste wood – before it isready for reuse. In accordance with EN 16485, Module
C3 also includes as outflows the CO2 equivalents ofthe carbon inherent in the wood product as well as therenewable and non-renewable primary energy (PERM
and PENRM) contained in the product.
Module D takes account of the thermal utilisation of the
product at its end of life as well as the ensuingpotential benefits and burdens in the form of a system
extension.
3.3
Estimates and assumptions
In principle, all of the material and energy flows for theprocesses required by production are established on
the basis of questionnaires.

Module A1 comprises the provision of wood fromforestry resources and the provision of additives.
Transport of these substances is considered in Module
4

Environmental Product Declaration STEICO SE – STEICOflex

3.4
Cut-off criteria
No known material or energy flows were ignored,
including those below the limit of 1%. Accordingly, thetotal sum of input flows ignored is certainly less than
5% of the energy and mass applied. This also
guarantees that no material or energy flows wereignored which display a particular potential forsignificant influences in terms of environmental
indicators.
3.5
Background data
All background data was taken from the GaBi
Professional Database 2020 Edition and the“Ökobilanz-Basisdaten für Bauprodukte aus Holz” final
report (S. Rüter, S. Diederichs: 2012).
3.6
Data quality
The primary data gleaned for 2019 was validated on
the basis of mass and in accordance with plausibility
criteria.
With the exception of forest wood, the backgrounddata used for wood materials for material and energy
purposes originates from 2008 to 2012. The provisionof forest wood was taken from a 2008 publication
which is essentially based on information from 1994 to
1997. All other information was taken from the GaBi
Professional Database 2020 Edition. The overall data
quality can be regarded as good.
3.7
Period under review
The data recorded for the primary system refers to
2019. Accordingly, all information is based on
averaged data from 12 consecutive months.
3.8
Allocation
The allocations comply with the specifications of the
EN 15804 and EN 16485, and are explained in detail in
S. Rüter, S. Diederichs: 2012. Essentially, the following
system extensions and allocations were carried out.

Module A3
On the other hand, the products manufactured in theplant are not associated co-productions. In accordancewith EN 16485, data which is only available for
production as a whole is allocated to the products on
the basis of the production volume (mass).
Energy generated from external disposal of waste
incurred during production is credited to the system bymeans of substitution processes, whereby it isassumed that the thermal energy would be generated
from natural gas and the substituted electricity would
correspond with the German power mix.
The credits achieved here account for significantly lessthan 1% of overall expenses.
Module D
The potential benefit through substitution of fossil fuelsin the course of generating energy with thermal
utilisation of the product packaging and the actual
product at its end of life is analysed in Module D,
whereby a system extension is applied for calculating
the substitutions under the assumptions describedabove.
3.9
Comparability
Basically, a comparison or an evaluation of EPD datais only possible if all the data sets to be compared
were created according to EN 15804 and the building
context, respectively the product-specificcharacteristics of performance, are taken into account.
The LCA was conducted using version 9.2 of the GaBi
ts 2020 software.
All background data was taken from the GaBi
Professional Database 2020 Edition or literary sources.

General information
The product characteristics inherent in the material(biogenic carbon and the primary energy contained
therein) are allocated in accordance with the physicalcriterion of mass.
Module A1
The processes in the upstream forestry chain concern
associated co-productions of logs (primary product)and industrial wood (co-product). The corresponding
expenses of this upstream chain were allocated on thebasis of log and industrial wood prices.
For the same reason, the expenses associated withsawn timber (primary product) and sawmill by-products(wood chips, co-product) were also allocated on thebasis of their prices in the upstream sawmill chain.

4. LCA: Scenarios and additional technical information
The scenarios on which the LCA is based are outlined
in more detail below.
Construction installation process (A5)
The information in Module A5 exclusively refers to thedisposal of packaging materials. No information isprovided on installation of the product. The volume of
packaging materials incurred per declared unit in

The product is recycled in the form of waste wood in
the same composition as the declared unit at the endof-life stage. Thermal recovery in a biomass power
station with an overall degree of efficiency of 54.54%
and electrical efficiency of 18.04% is assumed,
whereby incineration of 1 tonne of bone-dry wood(mass value as bone dry, consideration of efficiency,
yet ~18% wood moisture) generates approx. 968.37
kWh electricity and 7053.19 MJ useful heat. Converted
to the net flow of the bone-dry wood percentage
included in Module D and taking consideration of thepercentage of adhesives in waste wood, 47.1 kWhelectricity and 336.1 MJ thermal energy are produced
per declared unit in Module D.
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.

6. LCA: Interpretation
The interpretation of results focuses on the production
phase (Modules A1 to A3) as it is based on specificdata provided by the company. The interpretation

takes the form of a dominance analysis of theenvironmental impacts (GWP, ODP, AP, EP, POCP,

7

Environmental Product Declaration STEICO SE – STEICOflexADPE, ADPF) and the use of renewable/nonrenewable primary energy (PERE, PENRE).
Accordingly, the most significant factors for therespective categories are listed below.
6.1
Global Warming Potential (GWP)
CO2 product system inputs and outputs inherent inwood require separate consideration in terms of GWP.
A total of approx. 87.7 kg CO2 enters the system in theform of carbon stored in the biomass. Around 9.8 kg
CO2 bound in the form of the packaging material isaccounted for in Module A3 and released again in
Module A5.
The volume of carbon accounting for around 77.9 kg
CO equiv. ultimately stored in the wood fibre insulating
material is extracted from the system again whenrecycled in the form of waste wood.

Essentially, the generation of energy during the
manufacturing process accounting for 70% (Module
A3) and the packaging materials for the productaccounting for 8% (Module A3) are the most relevant
sources for emissions contributing to the acidification
potential.
6.4
Eutrophication Potential (EP)
35% of total EP is attributable to the provision ofelectricity and a further 20% is accounted for by theprovision of heat (both Module A3). The packaging forthe product makes a 12% contribution to EP (alsoModule A3).
6.5
Photochemical Ozone Creation Potential(POCP)The primary POCP contributions (35%) are accounted
for by energy generation during the manufacturing
process (Module A3). Direct emissions in the plant(also Module A3) account for a further 53% of total
POCP. The negative values recorded for the POCP in
Modules A2 and C2 are attributable to the negative
characterisation factor for nitrogen monoxide
emissions of the standard-conformant CML IA 2013
version (2001 – April 2013) in combination with the
GaBi Professional Database 2020 Edition truck
transport process used.
6.6
Abiotic Depletion Potential non-Fossil
Resources (ADPE)The essential contributions to ADPE (28%) are
incurred by the provision of additives for the product(Module A1). The consumables used also account for
25% of total ADPE (Module A3).

Fig. 2 CO2 product system inputs and outputs
inherent in wood. The inverse indications
suggested by inputs and outputs are in line with
the LCO CO2 flow analysis in terms of theatmosphere.
11% of the analysed fossil greenhouse gases areaccounted for by the provision of raw materials (entire
Module A1), 1% by transporting the raw materials(entire Module A2), and 88% by the manufacturing
process for the wood fibre insulation material (entire
Module A3).
Essential influential factors are represented by heatgeneration in the plant accounting for 37% and theprovision of electricity accounting for 39% as part ofModule A3, as well as the provision of additives usedas part of Module A1 accounting for 10% of fossil
greenhouse gas emissions.
6.2
Ozone Depletion Potential (ODP)
Emissions with an ozone depletion potential are
incurred almost exclusively (almost 100%) by theprovision of raw wood materials for the product.
6.3

Acidification Potential (AP)

6.7
Abiotic Depletion Potential – fossil fuels(ADPF)
39% of total ADPF is incurred by the generation ofheat in the manufacturing process and 28% by theelectricity consumed there (both Module A3). The
provision of additives for the product accounts for 21%(Module A1).
6.8
Renewable primary energy as energy
carrier (PERE)
Most of PERE use (69%) is attributable to the
packaging materials used and the renewable share ofelectricity consumption accounting for 26% (bothModule A3). 3% of total use is attributable to theprovision of additives for the product (Module A1).
6.9
Non-renewable primary energy as energy
carrier (PERE)
The use of PENRE is distributed across the provisionof product additives (21%, Module A1) and the
manufacturing process, with 38% for heat generationand 28% for electricity consumption there (bothModule A3).
6.10 Waste
54% of special waste is incurred in Module A3 during
the provision of packaging.
