The inventory is mainly based on industry data and is completed, where necessary, by secondary data.326The data set represents the North American production mix, focusing on the main technologies and other regional-specific characteristicsForeground system: Hot rolling is the method of rolling metal at a temperature high enough to avoid strain-hardening (work-hardening) as the metal is deformed. The ingots are preheated to about 1000 F and fed through a hot reversing mill and then through a continuous hot mill. Due to the fact that most aluminum hot-rolling facilities in North America include operations in which primary aluminum and secondary aluminum (or scrap) are melted (often together) and cast into large ingots which are subsequently rolled, the system of hot rolling was expanded to include metal/scrap re-melting and casting steps to avoid allocation. Specifically this process includes:
- Cradle-to-gate creation of primary aluminum ingot
- Cradle-to-gate creation of secondary aluminum ingot
- Shipment and handling of primary and secondary ingots, processed (clean) scraps and other ancillary materials
- Melting of ingots and scraps, refining, purification, alloying, and treatment of molten metal
- Casting Operations
- Breakdown hot rolling of cast slabs and rolling ingots
- Continuous hot rolling
- Edge trimming, finishing, coiling and packaging
- Recovery and handling of internal process scrap
- Maintenance and repair of plant and equipment
- Treatment of process air, liquids, and solids
Background system: Addressed below (electricity and energy)
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.RNA: Aluminum, primary ingot, at plant (data set not included in documentation) (data set not included in documentation) (data set not included in documentation)RNA: Aluminum, secondary ingot, at plant (data set not included in documentation) (data set not included in documentation) (data set not included in documentation)RNA: Remelting and Hot Rolling AA <u-so> (data set not included in documentation) (data set not included in documentation) (data set not included in documentation)GLO: Aluminum Scrap ts <u-so> (data set not included in documentation) (data set not included in documentation) (data set not included in documentation)Aluminum ingot used for finished products.

Combination with individual unit processes using this commodity enables the generation of user-specific (product) LCAs.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.
