General comment The values determined to calculate the LCA originate from verified Pekabex S.A. inventory data.
The data for the processes come from the following databases: Ecoinvent v.3.7.1, specific EPDs, ITB-Database. Specific data quality analysis was a part of external ISO 14001 audit.
The allocation rules used for this EPD are based on general ITB PCR A. Production of the hollow core slabs is a line process conduced in the manufacturing plan of Pekabex S.A. in Gdansk (Poland). Allocation was done on product mass basis. All impacts from raw materials extraction and processing are allocated in module A1 of the LCA. Impacts of the manufacturing plants of Pekabex S.A. were inventoried and allocated to the hollow core slabs production based on the production volume. Water and energy consumption, associated emissions and generated wastes are allocated to module A3 of the LCA.
The life cycle analysis (LCA) of the declared products covers: product stage – modules A1-A3, end of life – modules C3, C4 and benefits and loads beyond the system boundary – module D (cradle-to-gate with options) in accordance with EN 15804+A1 and ITB PCR A. The details of systems limits are provided in product technical report. Energy and water consumption, emissions as well as information on generated wastes were inventoried and were included in the calculations. Packaging materials were nota taken into consideration. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804+A1, machines and facilities (capital goods) required for the production as well as transportation of employees were not included in LCA.
