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 clean scrap at melting and fabrication (0%) is modeled as cut off criteria in the production phase. Thus, no credit should be given for the copper clean scrap after use of the product.
As a consequence, in case of credit calculation at end-of-life of copper wire, we recommend using the ICA copper cathode according to the amount used in the copper semi product.0The data set represents the country / region specific situation, focusing on the main technologies, the region specific characteristics and / or import statistics.Foreground system:
Copper wire is basically made of copper cathode and rarely of clean scrap. Therefore for this dataset 0 kg per tonne copper wire is based on copper clean scrap. The cathodes are melted and directly fabricated (casting and drawing) firstly to rodes and after to wire. European countries are reflected separately via their production volumes. The process route for copper cathode is 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 mix of primary data of European production and imported cathodes. The process route encompasses the following steps: mining and concentration (concentrate production, most often outside of Europe including transport distances for imported concentrate) and smelting and refining either via hydrometallurgy (leaching, solvent extraction, electro winning) or pyrometallurgy (smelting, converting, fire refining, electrolytic refining). Copper cathodes are produced from both, the hydro- and the pyrometallurgical route. Raw materials for the production are copper concentrate and scrap in case of pyrometallurgy.
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 wire for usage in electric motors (all kind of electric coils), conductors, inductors as well as for wiring in cars, houses / buildings, ships, aircrafts, etc.metals_copper production_dki.jpgLCI resultAttributionalNoneAllocation - market valueAllocation - net calorific valueAllocation - exergetic contentNot applicableThe mining and production of virgin copper (generally called primary 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. Low value by-products and further used slags or scraps such as ferro-silicate is cut off due to insignificant prices of by-product. For the produced sulphuric acid a credit was assigned (Substitution) since allocation is hard to apply due to missing prices of SO2 emissions (point of allocation).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 databases95.02005-2015NoneThe data set can be used for all LCA/CF studies where the product is needed.

For specific copper data set requests contact the Deutsches Kupferinstitut, www.kupfer-institut.de.No statementAll 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.thinkstepIABP-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 definedthinkstepThis background LCI data set can be used for any types of LCA studies.thinkstep2020-01-01T00:00:00.000ILCD format 1.1thinkstepNo official approval by producer or operator2020-01-01T00:00:00.00000.00.001Data set finalised; entirely publishedGaBi databasesthinksteptrueOtherGaBi (source code, database including extension modules and single data sets, documentation) remains property of thinkstep AG. thinkstep AG delivers GaBi licenses comprising data storage medium and manual as ordered by the customer.
