Aluminium foil is used in varying gauges and in a number of alloys for a variety of applications. It is available in thickness from 5 microns to 200 microns (i.e. 0,005 to 0,2 mm) and can be supplied in a range of finishes.
Similarly to the sheet production, the classical production route uses an aluminium rolling ingot (slab) as starting material for the production of rolled aluminium foil, which is first rolled into foil stock, i.e. the specific input for foil fabrication.
There are two routes of producing aluminium foil. The classical production route is carried out by cold rolling from foil stock with a thickness of 0,5 - 1,0 mm as input. For thinner foil thickness, the final rolling steps are carried out by double-rolling, i.e. rolling together two foil layers at the same time. During cold rolling a mineral oil fraction is used for cooling and lubrication.
Aluminium foil can also be produced directly through the strip casting process consisting in casting the molten aluminium directly into a strip which is cold rolled into a foil. This production route is increasingly gaining ground in Europe as it accounts for more than half of the production in 2010.
In the LCI dataset, a ratio of 43% classical route / 57% strip casting was used.
The foil production from as-cast ingot up to finished sheet generates about 390 kg of scrap by tonne of foil. These scraps are recycled into new ingot through remelting which is usually performed on-site in integrated cast houses. This internal recycling of process scrap is part of the LCI dataset for the foil production.
The background system is addressed as follows:
Electricity, Thermal energy: The electricity (and thermal energy as by-product) used is modelled according to the individual country-specific situation. The country-specific modelling is achieved on multiple levels. Firstly the individual power plants in service are modelled according to the current national grid. This includes net losses and imported electricity. Second, the national emission and efficiency standards of the power plants are modelled. Third, the country-specific fuel supply (share of resources used, by import and / or domestic supply) including the country-specific properties (e.g. element and energy contents) are accounted for. Fourth, the import, transport, mining and exploration processes for the energy carrier supply chain are modelled according to the specific situation of each power-producing country. The different mining and exploration techniques (emissions and efficiencies) in the different exploration countries are accounted for according to current engineering knowledge and information. Steam: The steam supply is modelled according to the individual country-specific situation with regard to the technology efficiencies and energy carriers used. Efficiencies range from 84% to 94% in relation to the representative energy carrier (gas, oil, coal). Coal, crude oil and natural gas used for the generation of steam are modelled according to the specific import situation (see electricity). Transports: All relevant and known transport processes used are included. Overseas transport including rail and truck transport to and from major ports for imported bulk resources are included. Furthermore all relevant and known pipeline and / or tanker transport of gases and oil imports are included. Energy carriers: Coal, crude oil, natural gas and uranium are modelled according to the specific import situation (see electricity). Refinery products: Diesel, gasoline, technical gases, fuel oils, basic oils and residues such as bitumen are modelled via a country-specific, refinery parameterized model. The refinery model represents the current national standard in refinery techniques (e.g. emission level, internal energy consumption,...) as well as the individual country-specific product output spectrum, which can be quite different from country to country. Hence the refinery products used show the individual country-specific use of resources. The supply of crude oil is modelled, again, according to the country-specific crude oil situation with the respective properties of the resources.Aluminium foil is commonly used for packaging and technical applicationsMetals_RER_Aluminium foil EAA update 2010.jpgPartly terminated systemAttributionalnonenone100.02010The dataset covers gate-to-gate system of Aluminium foil production in Europe.
