| Use advice for data set | System boundaries are shown in the flowchart. Waste flows, especially cutoffs from the steel manufacturing in A3, are treated within the module they occur via system expansion. |
| Technical purpose of product or process | Steel reinforcement bars (ribbed steel bars) that are made out of hot rolled products, transformed into straight ribbed bars, cut and bend, mesh, and combinations of these (special welded products) by European manufacturers. Sections are prefabricated by cutting, bending and welding by a Norwegian steel manufacturer. Reinforcement steel is used in the construction buildings and civil structures. EPD represents an average value for this product based on several production sites in Norway. Variance is <10% between sites. Typical product composition for reinforcement steel is described in the table below. Typically it consists of more than 99% of steel scrap. Material kg % Iron 0,98-0,99 98-99 Carbon 0,005-0,002 0,05-0,02 Manganese 0,03-0,07 0,3-0,7 Silicone 0,02 0,2 |

| General comment on data set | Data quality: Specific data for the product composition are provided by the manufacturer. The data represent the production of the declared product and were collected for EPD development in the year of study. Background data is based on EPDs according to EN 15804 and different LCA databases. The data quality of the raw materials in A1 is presented in the table below. Data has been collected in accordance with clause 6.3.6 in NPCR Part A for construction products and services. Specific data are used from the manufacturer for 2023; when collecting data, efforts have been made to create data sets as comprehensive as possible. that no data used >10 years old, or that it is in accordance with 15804. Allocation: The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials is allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. The allocation is made in accordance with the provisions of EN 15804. Incoming energy and water and waste production in-house is allocated equally among all products through mass allocation. Effects of primary production of recycled materials allocated to the main product in which the material was used. The recycling process and transportation of the material is allocated to this analysis. No other products and energy is produced at Smith Stål facility other than the declared product. Cut-off criteria: All major raw materials and all the essential energy is included. The production processes for raw materials and energy flows with very small amounts (less than 1%) are not included. These cut-off criteria do not apply for hazardous materials and substances. |
