Use advice for data set The scope of the study is cradle to gate with options, described as A1-A3, A4, C1-C4 and D modules. A4 scenario is calculated for average transport in Europe. In addition, impact data per 1 km of global shipment is supplied. Two endof-life scenarios (C1-C4 + D) are considered, one for recycling (scenario A), and one for 100% reuse of the steel components (scenario B). The end-of-life scenarios are calculated for the European region. Modules A1-A3 considers the life cycle stages from the extraction of raw materials to the point where the finished product is ready for shipment, including all transport stages. Steel scrap from the production processes is treated in a closed loop, so that it is returned to production as an input. Module A4 considers transport from Sikla’s facilities to the end user. Average impacts from transport to customers are given for the European Economic Area (A4EUR). In addition, standard impacts for transport to/from ports (A4PORT) and impacts per km of sea transport (A4SEA) are given for the global market, so that the impact of transport to non-EUR customers can be estimated using the sea distance from Hamburg to the local port. End-of-Life: Two scenarios are considered for the end-of-life phases (C1-C4 and D), one for a recycling route (scenario A) and one for a product reuse route (scenario B) Module C1A and C1B accounts for the disassembly of siMetrix. Modules C2A-C4A includes the transport to scrap handling facility, rubber waste incineration, steel scrap sorting and preparation for remelting, as well as landfilling of rubber incineration residues and a steel fraction assumed to be nonrecoverable. Module DA includes the impacts of melting and casting of recovered steel scrap, and the potential benefits of avoiding the use of virgin metals for the next product life cycle. Modules C2B-C4B accounts for transport, waste incineration and residue landfilling for the rubber components. Module DB includes the loads of transporting and remounting the steel components at a location 30 km from the first location. Loads from production, transport and replacement of the rubber components are included. Potential benefits from avoided production and transport of new steel product are included. Potential maintenance and refurbishment of the reused product is not included.
Technical purpose of product or process siMetrix is a multifunctional assembly system for medium load ranges that offers three-dimensional connection options. The siMetrix profile is a closed profile that is available perforated and unperforated. Both variants offer high torsional rigidity. The perforated variant offers numerous application possibilities such as through-hole installation of threaded rods, connection to walls and ceilings and others. A special feature of the system is its small number of variants: There is only one connection component with which cantilevers or traverses can be created on the profile and within the system. All connection components can be installed continuously and offer high flexibility on the construction site and during assembly. As long as the technical performance limits are not exceeded, all components can be reused as often as required. The system benefits from a reassuring level of safety guaranteed by tested corrosion resistance to Corrosivity Category C4-high according to EN ISO 12944- 2 and statically calculated constructions according to Eurocode 3 (DIN EN 1993). This EPD covers the siMetrix modular steel products, which are manufactured from construction steel and following zinc-magnesium coating. The starting material is steel strip, which is first coated with zinc-magnesium and then further processed. The following manufacturing process of these products includes cutting, punching, forming and welding of the steel input. Most connecting parts are first manufactured bare, then welded and finally zinc-nickel coated. Materials kg % Steel, low-alloyed 0.965 96.5 Rubber 0.035 3.5

General comment on data set Upstream and core: Product specific design data was given by Sikla (2024). Product sales data is estimated based on Siklas experience and knowledge. Company specific activity data was acquired from Sikla (2021). Upstream supplier activity data is modeled using the corresponding ecoinvent 3.10 production and market activity data based on geographic representations for Europe. Downstream: Scenarios were developed based on PCR and sales statistics. PCR defaults and database data were used. Conversion to process flows and LCI: Conversion to primary flows and environmental impacts was done using OpenLCA (version 2.2.0). Datasets from the ecoinvent v3.10 cutoff database with the EN15804 add-on developed by GreenDelta were selected according to their technological, geographical and temporal representativeness for the assessed process. Impact assessment: Open LCA software (version 2.2.0) was used to perform the impact assessment of this LCA. The latter refers to the LCIA characterization models, factors and methods as given in EN15804:2012+A2:2019, labelled “EN15804+A2 (EF 3.1)” in GreenDelta’s EN15804 addon to the ecoinvent 3.10 database The allocation is made according to the requirements of EN 15804. The energy, water and waste consumption of the company's own production is equally allocated to all products by mass allocation. Effects of primary production of recycled materials are allocated to the main product in which the material is used. The recycling process and transport of the material are allocated to this analysis. All major raw materials and all the essential energy are included. The production process for raw materials and energy flows that represent very small amounts (<1%) are not included.

1This impact category deals mainly with the eventual impact of low dose ionizing radiation on human health of the nuclear fuel cycle. It does not consider effects due to possible nuclear accidents, occupational exposure nor due to radioactive waste disposal in underground facilities. Potential ionizing radiation from the soil, from radon and from some construction materials is also not measured by this indicator.
2The results of this environmental impact indicator shall be used with care as the uncertainties on these results are high or as there is limited experiences with the indicator.
