Use advice for data set | The life cycle analysis of the declared product covers “Product Stage” A1-A3 modules, transport to site A4, “End of Life stage” C1, C2, C3, C4 modules and gains and loads beyond system in D module (Cradle to Gate with options) in accordance with EN 15804:2012+A1 and ITB PCR A. |
Technical purpose of product or process | This EPD covers the seven wire strands products with multilayer corrosion protection consisting of Zinc, wax and HDPE sheathing produced by Bekaert in manufacturing plant in Hlohovec, Slovakia. Bekaert (www.bekaert.com) is a global technological and market leader in advanced solutions based on metal transformation, and the world’s largest independent manufacturer of drawn steel wire products. Galvanized&waxed&HDPE sheathed stay cable strand is used as tension member for cable stay structures (mainly bridges). Bekaert’ tension strands for cable stay bridges feature tensile strengths up to 2 160 MPa. The strands are protected by layers of corrosion protective coatings (Figure 1). Inner wax coating is completely water resistant and has been specifically designed for stay cables, the wax features have high mechanical stability, and offer additional corrosion resistance to the metallic coating below. The final coating, HDPE sheath, consists of PE that has been tightly extruded around the strand. The standard wall thickness of the sheath is 1.5mm, though thicker sizes can be produced upon request. Bekaert HDPE extruded stay cable strands comply with fib bulletin 89Acceptance of cable systems using prestressing steels and PTI DC45.1-18 Recommendations for Stay Cable Design, Testing, and Installation. The strands successfully pass the pull-pull fatigue test of 2 000 000 cycles. Table 1 describes product’s standard specifications. More specific product technical data is available at Bekaert.com. |
General comment on data set | 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. |
