Reference year 2011
Name
Recycled silicon and aluminum alloy production ; Recycled silicon and aluminum alloy ; Consumption of circulating aluminum scrap
Use advice for data set When using this data set for Life Cycle Assessment, it is important to consider that it represents a process with geographical relevance for China, with specific energy mixes, particularly coal-based electricity generation. Users should align the system boundaries of their LCA study to include the stages of transport to the alloy production site, infrastructure of the production plant, chemicals and energy production, wastewater treatment, direct emissions, and scrap collection. The durability of building and equipment should be considered with a life span of 40 and 8 years, respectively. The European data sets used for the infrastructure and other background processes may require adaptation to reflect local conditions if applied in another geographical context.
Technical purpose of product or process The recycled silicon and aluminum alloy produced in this process is typically employed in the manufacturing of various aluminum products where secondary aluminum is suitable. Typical applications include the automotive and construction industries, components for electronic devices, and consumer goods where aluminum's strength-to-weight ratio and corrosion resistance are advantageous.

???common.completenessOtherProblemField??? Process of transport raw materials to recycled aluminum alloy site, infrastructure of aluminum alloy production plant, chemicals and energy production, wastewater treatment, direct emissions, and old aluminum scrap collection is included. Because coal plays a vital role in electricity generation of China, coal based electricity generation was considered. The infrastructure of aluminum alloy production plant, chemicals production, wastewater treatment data and relevant background data from European were used. The life time of building and equipment is 40 and 8 years, respectively.
