Key Data Set Information
Location CN
Reference year 2019
Name
Scrap Aluminum Melting and Ingot Casting ; Recycled Aluminum Ingots ; New Aluminum Scrap
Use advice for data set Users of this data set should ensure that material transportation assumptions are aligned with the specific geographic context of where the recycled aluminum ingots are being utilized. This data should not be directly applied to primary aluminum production processes. Variations in energy sources and efficiencies based on localized practices may affect the overall environmental impact and should be considered. Furthermore, if the recycled aluminum is used in applications with longevity and low turnover, such as construction, the recycling rate assumptions may need to be adjusted. Users should refer to Table 1 of the inventory for detailed energy inputs and material flows, ensuring relevance and timeliness of the data.
Technical purpose of product or process This process describes the melting of scrap aluminum and the casting of recycled aluminum ingots, which can be used for various manufacturing purposes. Recycled aluminum ingots are suitable for applications where the properties of new aluminum can be substituted with recycled material, reducing the need for primary aluminum production. Examples include construction materials, automotive components, packaging, and in some cases, consumer electronics or household goods. The process supports circular economy principles by utilizing scrap material efficiently.

Data selection and combination principles Inventories of energy input and material flow are collected from updated yearbook s, published papers, official reports and databases. The details of the inventory are presented as Table 1. It should be noted that the data for the material transportation assumptions are based on relevant studies, whic h may be slightly different from the actual situation. The life-cycle intensities of each end-use energy type are based on the results of our previous studies.
