General comment The data selected for LCA originate from ITB LCI questionnaires (manufacturing plant) completed by producer and verified via data audit. No data collected is older than five years and no generic datasets use d are older than ten years. The representativeness, completeness, reliability, and consistency are judged as good. The background data for the processes come from the following resources database Ecoinvent v.3. 10 minerals, additives, energy carriers, waste treatment, and packaging). The background data for energy is national based on KOBiZE reports (Polish electricity mix and combustion factors for fuels). Specific (LCI) data quality analysis was a part of the input data verification.
The allocation rules used for this EPD are based on general ITB PCR A ( 2023). Production of ceramic blocks is a line process executed by of CERPOL Sp. z o. o. in plant located in Kozlowice (Poland). Allocation was done on product mass basis. All impacts from raw materials extraction and processing are allocated in module A1 of the LCA . I mpacts from the global line production of CERPOL Sp. z o o. were inventoried and 100 were allocated ceramic blocks Water and energy consumption, associated emissions and generated wastes are allocated to module A3 Packaging materials were taken into consideration.
Type of the EPD is: cradle to gate with options. The following life cycle stages were considered. Production stage including: A1 Raw material extraction and processing, A2 Transport to the manufacturer and A3 Manufacturing, A4 Transport to Site , End of life stage: C1 Deconstruction, C2 Transport to waste processing, C3 Waste processing, C4 Disposal (landfill). This includes provision of all materials, products an d energy, packaging processing and its transport, as well as waste processing up to the end of waste state or disposal of final residues. EPD includes D module declaration of all benefits and loads beyond product system. Energy and water consumption, emi ssions as well as information on generated wastes were inventoried and were included. It can be assumed that the total sum of omitted processes does not exceed 5% of all impact categories. In accordance with EN 15804+A2, machines and facilities (capital go ods) required for the production as well as transportation of employees were not included in LCA. 99.8% materials submitted for the formulations and production data were taken into consideration. In the assessment, all available data from production have b een considered, i.e. all raw materials/elements used as per formulation process, utilized thermal energy for heating, and electric power consumption. Thus, material and energy flows contributing less than 1 % of mass or energy have been considered. It can be assumed that the total sum of neglected processes does not exceed 0.5 % of energy use and mass per modules.
