| Use advice for data set | The data set represents a cradle to gate inventory for secondary aluminium. It does not represent the typical consumer mix of aluminum ingots in Malaysia due to fact that also primary aluminum is imported. Considering the used technologies in this data set the environmental profile is applicable but with the background of the consumer market and to achieve decisions it should be treated with care because the imported primary aluminum would have a much higher environmental impact and might change the decision process. |
| Technical purpose of product or process | Provision of secondary aluminium ingots for sheet or profile making or other applications. |

| Technology description including background system | The production of secondary aluminium is done based on aluminium scrap in ratory and reverbatory furnaces. A share of 64% ratory furnace and 36% reverbatory furnace was adjusted based on European data. Malaysian specific data about aluminium recycling was not available. For moree information see the EAA environmental profile report. 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. 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. |
