Name
Concrete slab components made from steel
Technical purpose of product or process Steel components for concrete tiles, such as expansion joints and hollowcore slab hangers, maintain structural integrity. Expansion joints accommodate movement and ensure durability. Hollow-core slab hangers provide support for hollow-core slabs, enhancing stability and load distribution. These elements are essential for achieving reliable, longlasting tiled surfaces in construction projects. The products comply with the standard EN 1090-1:2009 + A1:2011. More information about the products covered by this EPD is available at https://semko.fi/fi/
General comment on data set All input and output flows of inventory data, type of materials used, energy consumption, transportation and wastes are primary data taken from the Manufacturer. The specific data quality coverages and limitations are also; • Geographical coverage: European and global environmental data are used for the flows when there is no specific data for the current situation in Finland. • Time period coverage: Inventory data from year 2023 with 12 consecutive months was collected from manufacturing facility. Generic data from Ecoinvent v3.10.1 is not older than 5 years. Although year 2023 is not the latest full calendar year when conducting the current EPDs, the date of the data is not expected to have a major impact on the reliability of the study results, as the manufacturer has not reported any changes that would significantly affect the product phase calculations or results. • Technology coverage: The objective of the study is to use the data that apply to average technology which represents the actual situation. Even if the data in Ecoinvent v3.10.1 which represents the current situation best are used, these data are expected to show limited global variability. The data quality assessment has been conducted on the cradle-to-gate (A1-A3) impacts which are the mandatory stages and represent measured data. The effect of distribution (A4), installation (A5) and end-of-life (C1- C4) have been assessed as these stages are scenario-based and provide additional information. Inventory data of product stage (A1-A3) and the scenarios (A4-A5 and C1-C4) was collected via questionnaire and personal contact with representative of the Manufacturer. Allocation is required if some material, energy, and waste data cannot be measured separately for the product under investigation. In this study, as per EN 15804, allocation is conducted in the following order; 1. Allocation should be avoided. 2. Allocation should be based on physical properties (e.g. mass, volume) when the difference in revenue is small. 3. Allocation should be based on economic values. The allocations in the ecoinvent 3.10.1 datasets used in this study follow the Ecoinvent system model ‘Allocation, cut-off, EN15804’. Raw material use was known by product level, so allocation was not needed. Avoiding allocation could not be avoided for following inputs as the information was only measured on factory process level: • Energy consumption • Manufacturing waste • Packaging materials • Welding gases • The inputs were allocated to studied products based on production volume (mass in kilograms). The study does not exclude any modules or processes which are stated mandatory in the EN 15804:2012+A2:2019 and the applied PCR. The study does not exclude any hazardous materials or substances. The study includes all major raw material and energy consumption. All inputs and outputs of the unit processes, for which data is available for, are included in the calculation. There is no neglected unit process more than 1% of total mass or energy flows. The module specific total neglected input and output flows also do not exceed 5% of energy usage or mass.

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.
