General comment The values determined to calculate A3 originate from verified Progress LCI inventory data. A1 values were prepared considering European made steel products based on Ecoinvent. Allocation for steel production impacts is done in accordance with LCI data for Steel products Report compiled by Brayan Hughes and William Hare (2012 for World Steel Association).
The allocation rules used for this EPD are based on general ITB PCR A. Production of products is a line process in a manufacturing plant located at Hlohovec, Slovakia. Allocation of impacts is done on product mass basis. All impacts from raw materials production (wire rod, wax, HDPE, wood packaging, paper, foil and pallets) are allocated in A1 module of the LCA. 99% of the impacts from a line production were allocated to product covered by this declaration. Module A2 includes transport of raw materials such as steel and HDPE from supplier to manufacturing plant. Municipal wastes of the factory were allocated to module A3. Energy supply and electricity was inventoried and 100% was allocated to the product assessed. Emissions in the factory are assessed using statistical KOBIZE 2019 emission factors for energy carriers.
99% materials and 100% energy consumption (grid electricity, gas, LPG) were inventoried in the factory 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 (main input is steel Wire Rod and HDPE), utilized thermal energy, and electric power consumption, direct production waste, and available emission measurements.
Tires consumption for transport was not taken into account. Precomponents like labels, tapes, minor chemicals with a percentage share of less than 0.2% were not included in the calculations. It is assumed that the total sum of omitted processes does not exceed 1% of all impact categories. In accordance with EN 15804 machines and facilities (capital goods) required for and during production are excluded, as is transportation of employees.
