General comment The data for the calculation of modules A1-A3 are derived from verified LCI inventory data from the plant. According to Annex E of PN-EN 15804 + A2 data quality assessment was carried out. For technical representativeness, processes with “very good” quality represent 99% of the values for climate change indicators. For geographical and temporal representativeness, the process rating was “very good”.
Allocation in this study was created in accordance with the document: ITB PCR A guideline. The production of all products declared takes place at the plant in Wielkie Rychnowo, Poland. Input data for the production plant have been inventoried. The results obtained are representative mass based average for Construction Membranes and Vapour Barrier Membranes produced by CONKRET.
All data regarding the recovered materials as well as raw materials used in production are allocated to module A1. The energy and fuel consumption as wel as generating waste for the entire production process has been inventoried and included in module A3.
The life cycle analysis (LCA) of the declared products covers: product stage – modules A1-A3, end of life – modules C1-C4 and benefits and loads beyond the system boundary – module D (cradle-to-gate with options) in accordance with EN 15804+A2 and ITB PCR A, v. 1.6. All materials and energy consumption inventoried in factory were included in calculation. Office impacts were also taken into consideration. In the assessment, all significant parameters from gathered production data were inventoried and were included in the calculations, i.e. all material used per formulation, utilised thermal energy, internal fuel and electric power consumption, direct production waste, water consumption and all available emission measurements. At the production plant were inventoried:
- 100% of the input materials;
- 100% of the electricity and fuel consumption.
The assessment takes into account all relevant parameters from the collected production data including: all materials used for production, packaging materials, electricity used, fuels and direct production waste. Substances with a percentage of less than 1 % of total weight were excluded from the calculation. For the purposes oft he analysis it has benn assumed that the total sum of omitted processes does not exceed 0.5% of all impact categories.
