| Use advice for data set | Scope: This EPD is based on a declared unit of 1 metric ton of average voestalpine rails produced at the production site in Donawitz (Austria). System boundary: The life cycle assessment of voestalpine rails refers to a cradle-to-gate analysis with options. The following lifecycle phases are taken into consideration in the analysis: Module A1-A3 | Production stage The product stage includes upstream burdens of processed intermediates (mainly steel blooms) and raw materials including the corresponding transports to the production site in Donawitz. Material and energy flows needed for the integrated steel mill as well as the subsequent rolling, heat treatment and finishing of voestalpine rails were recorded on site. Electricity is provided at Donawitz in a power station where furnace gases are used as fuel. Since more energy is used than is supplied by the site's power station, natural gas and electricity is additionally supplied from the Austrian grid. No packaging is needed for the delivery of the product. Module C3 | Waste treatment Product flows that reach Module D for recycling leave the product system in C3. Environmental impacts resulting from the grinding and sorting of steel scrap are not included. Module C4 | Landfilling Module C4 declares the environmental impacts incurred by landfilling (5% of the product). Module D | Credits and loads beyond the system boundary The potential for substituting primary steel with a recycling scenario (95% of the product) is set forth in Module D. | ||

| Technology description including background system | The starting material for the production of rails at voestalpine is crude steel made in the primary route (blast furnace, LD steelmaking plant) at the Donawitz site. The molten crude steel is cast into blooms using a continuous casting method. The blooms are temporarily stored in the bloom storage unit or in a holding pit and heated to rolling temperature in a controlled manner in the walking beam furnace. The rails are then pre-rolled in the reversing break-down mill (BDM). Final shaping of the rails takes place in the ultra-flexible rail mill (UFR). Depending on customer specifications, the rails are cooled naturally or heat-treated to achieve desired properties. Further production stages: ▪ Vertical and horizontal straightening ▪ Non-destructive testing (visual testing, flatness testing, eddy current testing and ultrasonic testing) ▪ Final straightening ▪ Cutting ▪ Drilling ▪ Final acceptance ▪ Storage and shipping Technical data: This EPD refers to all products of voestalpine Rail Technology GmbH in a variety of different steel grades, dimensions, shapes and as-delivered conditions. Declared unit: This environmental product declaration refers to a declared unit of 1 metric ton of average voestalpine rail. | ||
