A Method for Assessment of Recyclability of Aluminum from Incinerated Household Waste

Secondary aluminum production is required for the conservation of the environment. It can significantly reduce greenhouse gas emissions and energy consumption and reduce the consumption of alumina, a source of primary aluminum. Secondary aluminum production requires sorting processes for the metal scrap before starting the refining process. Salt slags generated from both primary and secondary aluminum production need to be recycled/treated as they are considered hazardous byproducts. This review paper discusses the methods used for sorting and refining aluminum waste and managing and utilizing slag cakes/slag from recycling techniques.

The aim of the study is melting the AlSi7Mg0.3 alloy chips, which are used in the production of automobile wheels, in sizes smaller and larger than 2 mm, in two different salt mixtures, at different ratios and by creating application differences, and to reveal the recovery and coagulation efficiency. Low-pressure die casting was used to produce the wheel, and TGA was used to examine the oxidation behavior of the chips under temperature. For a more efficient recycling, coarse and fine grains should be treated separately. Since the CaF2 solubility is higher in the ratio of 50:50 NaCl:KCl, it has a supporting effect in coagulation for the chips with a large surface area. It has been determined that the chips with a small surface area should be stirred in order to obtain suitable coagulation efficiency. The study is important in terms of the use of AlSi7Mg0.3 alloy used in automobile wheels, thus assessing the aluminum recycling efficiency in the production of aluminum alloy wheels, which is increasingly play a role in the automotive industry.
