17. Appendices Table 32: Expectations of future developments regarding Eco-Design in the construction sector 104 The European Steel Industry’s Contribution to an Integrated Product Policy – Final Report
17.3. LCA Case Studies 17. Appendices In the following section, the system boundaries for the selected case studies are described as well as selected results will be presented and discussed. Chapter 17.3.1 gives an overview on major ecological parameters for steel types used within the selected case study products. 17.3.1. Ecological Parameters of considered Steel Types As shown in Figure 33, the tailor welded blank case study and the composite flooring system deal with carbon steel, the stainless steel roof case study focuses on stainless steel and the consumer product are produced using both carbon and stainless steel. Tailor welded blanks Floor system Figure 33: Overview on used steel types within selected case studies The table within Figure 33 provides an overview on characteristic values describing selected ecological Life cycle Inventory (LCI) and Life Cycle Impact Assessment (LCIA) parameters for the different steel types consumed in the case study products. LCI parameters presented are the total primary energy demand in MJ and the resulting carbon dioxide emission to air in kg for the production of 1 kg steel. Selected LCIA criteria are based on the methodology developed by the Centre of Millieukunde (Netherlands, CML 2001). This selection covers the: ♦ Global warming potential (GWP) in kg CO2 equivalents ♦ Acidification potential (AP) in kg SO2 equivalents ♦ Eutrophication Potential in kg phosphate-equivalents (PO4-eq.) Consumer product Stainless steel roof ♦ Photochemical Ozone Creation Potential (POCP) potential in kg ethylene-equivalents (C2H4-eq.) The overview shows that for the selected ecological parameters the values can differ quite a lot which is due to the different steel materials and required amount of alloying elements. At this stage it is The European Steel Industry’s Contribution to an Integrated Product Policy – Final Report 105
