General comment The data selected for LCA originate from ITB-LCI questionnaires completed by BSP sp. z o. o. and verified during data audit. No data collected is older than five years and no generic datasets used are older than ten years. The representativeness, completeness, reliability, and consistency is judged as good. The background data for the processes come from the following resources database Ecoinvent v.3.10. 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. Production of the BSP KWRZ substructure system with BSP KW4 PAS passive consoles is a line process conducted in plant of BSP sp. z o. o. located in Przasnysz (Poland). Allocation was done on product mass basis. All impacts associated with the extraction and processing of raw materials used for the production of the declared product are allocated in module A1 of the LCA. Impacts from the global line production of BSP sp. z o. o. were inventoried and 100% were allocated to BSP KWRZ substructure system with BSP KW4 PAS passive consoles production. Water and energy consumption (electricity, natural gas, LPG), associated emissions and generated wastes are allocated to module A3. Packaging materials were taken into consideration.
Minimum 99.0% input materials and 100% energy consumption (electricity, natural gas, LPG) were inventoried in a processing plant and were included in the calculation. In the assessment, all available data from production have been 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 1 % of energy usage and mass per modules A or D. Machines and facilities required during production are neglected. The packaging products (stretch film, carkgs, pallets, etc.) are included.
