12. Recycling Methodology All scrap arising at the end of life is considered via a downstream credit in the amount of the ‘value of scrap’. To assign an end of life credit, a material recovery rate is to be specified which represents in the best case the exact individual final product characteristic, but in most cases is considered as an average or sector-specific recovery rate. Upstream burden ‘Value of Scrap ’ Material Production Product Manufacturing Product in Use Figure 10: Schematic implementation of the IISI Recycling Approach Product ’s End of Life Downstream credit ‘Value of Scrap ’ Even though Figure 10 includes the life cycle phases of product manufacturing, product in use and the product’s end of life, the LCI data generated and provided by EUROFER and IISI does not include these life cycle steps. What is included is the material/steel production including the upstream burdens as well as the end of life scrap credit, which is considered in the ‘value of scrap’. The ‘value of scrap’ ecoprofile is calculated on the basis of the LCI data from the IISI LCI study in 2000 provided by IISI and following the IISI recycling methodology. 12.4. Outlook The recycling methodology is incorporated within the IISI LCI data for the 14 steel products for which they provide data, and therefore the data that is provided on the European Commission’s ELCD will also contain the credits and burdens associated with the scrap in the steel production process. The methodology has also been incorporated within the GaBi 4 modelling software for use within the individual case study products for this project. This model is available for use by IISI and other approved organisations and member companies. 48 The European Steel Industry’s Contribution to an Integrated Product Policy – Final Report
13. PROJECT PART C: MATERIAL FLOW ANALYSIS 13.1. Introduction and motivation for the MFA project 13. Project Part C: Material Flow Analysis The three project parts address different areas of work. With their complementary characteristic, they provide an important contribution to the achievement of the goals set. In view of the project package, the following logical relationship is given: The very practical, first part addresses the tool and communication level of IPP: What kind of support is expected and needed by customers of the steel industry to cope with the requirements in the context of IPP and how should this information be presented? The result of the project is the concept of an Eco-Design package focussing on the actual industry needs. The second part delivers the necessary data and models for the first part; LCA and LCI models according to the methodological settings of EUROFER: Which Life Cycle Inventories are to be applied how? The results are (generic) LCA models of steel applications (products) in the three main sectors considered within this project. The third part delivers the necessary material flow figures to ensure high-quality results in the second part of the project: Which data is needed to determine the actual steel recycling rate of a generic product and which method to chose for this macro-economic material flow analysis? Figure 11: Correlation of Project A, B and C Figure 11 highlights the correlation between project part A, the Eco-Design package, project part B, the LCI/LCA model(ling), as well as project part C, the MFA data collection. The figure gives a clear indication on the interrelated and systematic structure of the overall EUROFER IPP project. 13.2. Goal of the MFA Whereas conventional MFA studies describe the material and energy flows into, throughout, and out of an economic system for a defined period of time, the specific goal of the work on MFA undertaken within the context of the EUROFER IPP project was to set up a high-quality data basis for calculating the (sector-specific) recycling rate(s) – to be applied in the LCI calculations of project part B.
