Product description
Accoya® wood is made of Radiata Pine (species) from New Zealand. The sawn wood is transported toArnhem where it is acetylated. The acetylation process increases the stability and reduces the impact ofnatural elements significantly. For this reason warranties are provided up until 50 years, with an expected
service life of a minimum of 60 years. During acetylation, the hydroxyl groups within the wood arereplaced by acetyl groups, which are more chemically stable and attract less moisture. Minimal acetic
anhydride or acetic acid residue is present in the final product (<0.5%), making Accoya® a non-toxic
material, resulting in wood that can be burned/processed similarly to unmodified wood.
Accoya® wood is a modified wood product, which means it can be used in various circumstances. The
wood can made in various dimensions, depending on the application and demands of the end-user.
It is recommended to use stainless steel fasteners in accordance with EN 10088-1, for example fasteners
made of A2 or A4 stainless steel.
Accoya® wood is certified as FSC® mix (minimal 70% FSC® and the rest controlled wood)and Cradle toCradle® Gold among other certificates. Please consult the website for an up-to-date overview of thesustainability credentials. https://www.accoya.com/uk/sustainability/ecolabels-acquired/

Reference Service Life
The service life specified by the manufacturer is 60 years for the correct application of the product andthe maintenance schedule recommended by the manufacturer.
There is no post-consumer take-back program. Considering the longevity of Accoya®, the company has
not been in existence long enough for this type of initiative. Accsys, the producer of Accoya® wood has a
pre-consumer offcuts take-back reuse scheme in place, which collects offcuts to be reprocessed intoanother product. This is not included in the calculations.

Biogenic carbon storage
Biogenic carbon storage during the lifetime of Accoya® sheet pile is calculated according to the EN16449,
and with 1 kg biogenic carbon as equivalent to 44/12 kg of CO2:
802.4 kg CO2eq/m3 = 218,64 C/m3

Comparability
A comparison or evaluation of EPD data is only possible if all datasets have been made in accordance with
EN 15804 and the same product-related standard properties and modules have been taken into account.

System boundaries
The LCA study was created for "Cradle to Gate" according to the modules below and are the basis forcalculations or can be used for further calculations. All declared values relate to the specified declaredunit. According to the European standard EN 15804 +A2
The environmental performance of building materials is categorized in four modules corresponding to3

different lifecycle phases in the building material; Modules A (production of materials and construction), B(use phase), C (end-of-life phase of the building) and D (loads and benefits outside the system boundary).

For Accoya® wood, the modules A1-3 have been examined.

Allocations
Within the SimaPro-process, economic allocation has been applied between Accoya® -wood and the coproduct acetic acid.

Production process
The production process is summarized in the flowcharts. The production process of Accoya® wood is withthe module A1-3.
Flowchart Accoya® woodExplanation Flowchart and Life Cycle per phase
Description of production (A1-3)
The Radiata Pine is harvested, sawn to planks and dried in New Zealand. The wood is transported by shipfrom New Zealand to Rotterdam and then transported to the factory.
4

In the factory at Arnhem (NL), the planks are first selected for quality. Then acetylated, in a fullyautomated process. The acetic acid that is used, is coming from two different sources. During theacetylation process hydroxyl groups within the wood are replaced by acetyl groups, which are morechemically stable and attract less moisture.

After acetylation, the planks are transported to a warehouse or transported to the customers (buildingindustry). Planks can be cut, planned, profiled and/or finger jointed and transported to the construction
site by truck.

Representativeness of the production process
Purchase of raw materials
Because Accsys does not have fixed suppliers for additional materials, fixing materials, spruce and foil,
data from the Ecoinvent database, version 3.6 and the NMD database version 3.4 were used.

Data quality
Accsys has handed over the physical and digital documentation and drawings, as well as a material
statement with the quantities of material required for the tested element.
Energy consumption of equipment required to manufacture the product under investigation is based on
consumption figures for 2021.
With the exception of the manufacturing phase, standard values have been used where appropriate inaccordance with Ecoinvent 3.6. This applies in particular to transport distances, processing in the waste
phase and the choice of means of transport. Return transports loaded/unloaded are as per themanufacturer's instructions.
Production processes can change over time. The information used in this LCA of the production process ofthe element is based on measurements and observations from 2021 (energy, waste percentages,quantities net per element, production volume). Data from supplying companies are all of the mostrecent date possible.

Accountability
The LCA study was conducted by Agrodome B.V. in 2021.
The data provided by Accsys have been extensively discussed with Agrodome B.V.
The final version of the LCA study has been submitted to SGS for external peer review.
The LCA is carried out according to EN 15804 +A1 and +A2 in compliance with the standards from the ISO
14000 series: 14025, 14040 and 14044.
When calculating the environmental impact categories, Simapro, version 9.0.0.49 and environmental datafrom the Ecoinvent database, version 3.6 are used.
When making calculations in Simapro, the long-term effects (emissions that can occur after 100 years) are
not taken into account. The effects of capital goods and infrastructural processes are included.
