The inventory is mainly based on industry data and is completed, where necessary, by secondary data. This data set is based on primary data from internationally adopted production processes, connected with regional precursor chains.
In this data set the used copper scrap is modeled as cut off criteria in the production phase. Thus, no credit should be given for the copper scrap after use of the product.102The data set represents the country / region specific situation, focusing on the main technologies, the region specific characteristics and / or import statistics.Foreground system:
Copper sheet is basically made of copper cathode (virgin copper) and scrap from outside as well as process internal scrap e.g. turnings, cuttings (ca. 810 kg copper scrap per tonne copper sheet). The process route for copper cathode can be region specific e.g. Outokumpu process, Mitsubishi process, El teniente process, etc. The production process in principle is based on similar technology worldwide. The database encompasses for both routes the state of the art as described in the EU document on Best Available Technology of IPPC. The process route encompasses the following steps: mining and processing (concentrate production), hydrometallurgy (leaching, solvent extraction, electro winning) and pyrometallurgy (smelting, converting, fire refining, electrolytic refining). Copper cathodes are produced from both, the hydro- and the pyrometallurgical route. The semi-fabrication process for copper sheet includes the process steps melting and alloying, casting and rolling. Raw materials for the production are copper ore and scrap (pyrometallurgy), as well as clean scrap (semi-fabrication).
Background system:
Electricity: Electricity is modelled according to the individual country-specific situations. The country-specific modelling is achieved on multiple levels. Firstly, individual energy carrier specific power plants and plants for renewable energy sources are modelled according to the current national electricity grid mix. Modelling the electricity consumption mix includes transmission / distribution losses and the own use by energy producers (own consumption of power plants and "other" own consumption e.g. due to pumped storage hydro power etc.), as well as imported electricity. Secondly, the national emission and efficiency standards of the power plants are modelled as well as the share of electricity plants and combined heat and power plants (CHP). Thirdly, the country-specific energy carrier supply (share of imports and / or domestic supply) including the country-specific energy carrier properties (e.g. element and energy content) are accounted for. Fourthly, the exploration, mining/production, processing and transport processes of the energy carrier supply chains are modelled according to the specific situation of each electricity producing country. The different production and processing techniques (emissions and efficiencies) in the different energy producing countries are considered, e.g. different crude oil production technologies or different flaring rates at the oil platforms.
Thermal energy, process steam: The thermal energy and process steam supply is modelled according to the individual country-specific situation with regard to emission standards and considered energy carriers. The thermal energy and process steam are produced at heat plants. Efficiencies for thermal energy production are by definition 100% in relation to the corresponding energy carrier input. For process steam the efficiency ranges from 85%, 90% to 95%. The energy carriers used for the generation of thermal energy and process steam are modelled according to the specific import situation (see electricity above).
Transports: All relevant and known transport processes are included. Ocean-going and inland ship transport as well as rail, truck and pipeline transport of bulk commodities are considered.
Energy carriers: The energy carriers are modelled according to the specific supply situation (see electricity above).
Refinery products: Diesel fuel, gasoline, technical gases, fuel oils, lubricants and residues such as bitumen are modelled with a parameterised country-specific refinery model. The refinery model represents the current national standard in refining techniques (e.g. emission level, internal energy consumption, etc.) as well as the individual country-specific product output spectrum, which can be quite different from country to country. The supply of crude oil is modelled, again, according to the country-specific situation with the respective properties of the resources.Copper sheet is typically used in building and construction (roofing, cladding, etc.). For industrial use e.g. electrical engineering the thickness is in general finer.Metals_Copper production_DKI.JPGLCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentNot applicableThe mining and production of virgin copper (generally called copper cathode) is inseparably coupled with co- and by-products e.g. gold, silver, nickel, molybdenum, etc. These products could only be considered and assessed by allocation. Valuable metal by-products (Au, Ag, Ni, Mo) are allocated by market value. Steam was not allocated because no sufficient data was available. For the produced sulphuric acid a credit was assigned (Substitution).All data used in the calculation of the LCI results refer to net calorific value.NoneCut-off rules for each unit process: Coverage of at least 95% of mass and energy of the input and output flows, and 98% of their environmental relevance (according to expert judgment).NoneLCI modelling is fully consistent.NoneFor details please see the document "GaBi Databases Modelling Principles"NoneSachbilanz einer Ökobilanz der Kupfererzeugung und -verarbeitungCopper extraction from the 60's into the 21st centuryWorld Metal Statistics YearbookGaBi databases95.01992-2001NoneThe data set can be used for all LCA/CF studies where the product is needed. Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs.
The data set represent a cradle to gate scenario for the production of copper sheet including the cut off criteria for the specific amounts of copper scrap used in this model. For specific copper data set requests contact the Deutsches Kupferinstitut, www.kupfer-institut.de.All relevant flows quantifiedAll data sets in the GaBi Databases are constantly used, compared, benchmarked and reviewed by a broad GaBi user community. Calculated results are published frequently in various external, professional and third party LCA literature, papers, and other media within industry, academia and politics. The incorporation of feedback provided by the GaBi users is standard practice in the maintenance and update procedure, and leads to stable, quality-assured and constantly improved data. The internal review is done with several iterative steps involving raw data validation, raw data documentation, representativeness, completeness and consistent modelling with regard to ISO 14040 and 14044. The data set documentation is correct in respect to the appropriateness of the information available. It includes all relevant information in relation to data quality and the scope of application of the respective LCI result.PE INTERNATIONALLBP-GaBiGaBi conformity systemFully compliantFully compliantFully compliantFully compliantFully compliantNot definedUNEP SETAC Life Cycle InitiativeNot definedNot definedNot definedNot definedNot definedNot definedILCD Data Network - Entry-levelNot definedNot definedFully compliantNot definedNot definedNot definedPE INTERNATIONALThis background LCI data set can be used for any types of LCA studies.PE INTERNATIONAL2014-12-01T00:00:00+01:00ILCD format 1.1PE INTERNATIONALNo official approval by producer or operator2014-12-01T00:00:00+01:0009.00.000Data set finalised; entirely publishedGaBi databasesPE INTERNATIONALtrueOtherGaBi (source code, database including extension modules and single data sets, documentation) remains property of PE INTERNATIONAL AG.
