The reinforcement steel is then shaped according to customer specifics by cutting and bending at the manufacturer in Norway, without the need for welding. Technical data: The product certified is in accordance with standards: NS 3576-1, NS 3576-3 and NS 3576-4. Recycled content of steel: >99% steel scrap. Reinforcement steel is used in the construction of buildings and civil structures, and is used to strengthen concrete by keeping it in tension. Product specification: Typical product compostion for reinforcement steel is described in the table below: Materials Iron Carbon Manganese Silicone kg 0,98-0,99 0,005-0,002 0,03-0,07 0,02 % 98 - 99 0,05-0,02 0,3-0,7 0,2 Market: Norway Reference service life, product: Not relevant. LCA: Calculation rules Declared unit: Per kg steel System boundary: Cradle to gate (A1-A3) including transport from manufacturer to customer (A4). System boundaries are shown in the flowchart. Waste flows, especially cut-offs from the steel manufacturing in A3, are treated within the module they occur via system expansion. Data quality: General requirements and guidelines concerning use of generic and specific data and the quality of those are as described in EN 15804: 2012, clause 6.3.6 and 6.3.7. The data is representative according to temporal, geographical and technological requirements. Cut-off criteria: All major raw materials and all the essential energy is included. The production process for raw materials and energy flows that are included with very small amounts (<1%) are not included. This cut-off rule does not apply for hazardous materials and substances. Temporal: Data for use in module A3 is supplied by the manufacturer and consists of the recorded amount of specific material and energy consumption for the product studied. Specific data has been collected in 2014. Generic data has been created or updated within the last 10 years. Allocation: The allocation is made ​in accordance with the provisions of EN 15804. Incoming energy and water and waste production inhouse 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. NEPD-321-200-EN Ribbed bars made from reinforcement steel, in the form of mesh as well as straight and shaped bars, Smtih Stål AS 3 Geographical: The geographic region of the production sites included in the calculation is Europe. Technological: Data represents technology in use. Data for module A1 consists of specific data derived from environmental product declarations from suppliers. This data is then weighted according to the specific contribution in the final production mix in module A3. All other data are gathered from GaBi 6. LCA: Scenarios and additional technical information The following information describe the scenarios in the different modules of the EPD. The scenario for transport distances and transportation modes from suppliers to manufacturer represents both recorded and calculated routes and distances from factory gates in Europe to Smith Stål Øst in Holmestrand, Norway.

LCA: Results The results shows that the most significant impacts comes from the production of steel, given in A1. The steel is shipped from European manufacturers, giving a high impact in A2. Module A3 includes heating of the manufacturer's warehouse, cutting and bending of reinforcement steel, as well as the treatment of wastes.

Negative impact results in this category essentially means that the use of transport will in effect clear smog formation. A4 recalculated with the ReCiPe impact assessment methodology gives 5,04E-05 kg NMVOC. 2 The negative numbers here is traced back to supplier EPD data used in A1. A similar negative result in ADPM has been seen in other steel EPD’s where Worldsteel datasets has been used. The consensus is that the ADP Elements impact category has some uncertainties, and the negative result is due to system expansion and crediting of by-products (EAF Dust – dust from recycled material in an electric arc furnace) in the Worldsteel data set.
