General comment The data selected for LCA originate from ITB-LCI questionnaire completed by GLOBAL SYSTEM Sp. z o.o. and verified during LCI 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.3.9.1 (steel, sheet metal, PVC, aluminium, welding products, paints, graphite, fibre matts, EUR-flat pallet). Specific (LCI) data quality analysis was a part of the input data verification. Where no background data is available, data gaps were complemented by manufacturer information and literature research.
The allocation rules used for this EPD are based on general ITB’s document PCR v1.6., 2023. Production of the dock shelter products is a line process (as presented in Figure 2) conducted in the manufacturing plant located in Podegrodzie (Poland). Input and output data from the production is inventoried and allocated to the production on the mass basis. The declaration covers a wide range of fire curtains. Their production resources and processing stages are basicly similar, so it was possible to average the production by product mass and reference size. The reference is calculated as the representative selection of the product group.
Minimum 99.5% input materials and 100% energy consumption (electricity, gas, other) were inventoried in a processing plant and were included in the calculation. In the assessment, all significant parameters from gathered production data are considered, i.e. all material used per formulation, utilized thermal energy, and electric power consumption, direct production waste and available emission measurements. Tires consumption for transport was not considered. Substances with a percentage share of less than 0.1% of total mass were excluded from the calculations. The packaging products (wooden pallets) are included.
