General comment The quality requirements for the life cycle assessment were set according to the EN ISO 14044 standard (4.2.3.6) and EN 15804
standard (6.3.7). This LCA study follows the standard EN 15804:2012+A2:2019 and RTS PCR and no decisions are made based on the
values. The study does not consider long-term emissions (i.e. over 100 years). Impact assessment characterization factors are aligned
with EF 3.1. The calculations were conducted using One Click LCA -tool which is a cloud-based LCA software in compliancy with EN
15804 -standard.
Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation.
In this study, as per EN 15804, allocation is conducted in the following order:
1. Allocation should be avoided.
2. Allocation should be based on physical properties (e.g. mass, volume) when the difference in revenue is small.
3. Allocation should be based on economic values.
The allocations in the Ecoinvent 3.10.1.1 datasets used in this study follow the Ecoinvent system model ‘Allocation, cut-off,
EN15804’. During calculations these allocations were made:
Module A3
• Electricity, fuel consumptions reason for allocation: only measured on factory level.
• Waste and wastewater from production, reason for allocation: only measured on factory level.
Energy and waste have been allocated based on production volume.
The study does not exclude any modules or processes which are stated mandatory in the EN 15804:2012+A2:2019 and the applied
PCR. The study does not exclude any hazardous materials or substances. The study includes all major raw material and energy
consumption. All inputs and outputs of the unit processes, for which data is available for, are included in the calculation. There is no
neglected unit process more than 1% of total mass or energy flows. The module specific total neglected input and output flows also
do not exceed 5% of energy usage or mass. Materials not considered in this study: oil used for moulds preparation and the Euro
pallets used multiple times for outside storage of Product 1 (the amount used is less than 0,01% per DU for both materials)
