The aim of this study is to compare the potential environmental impacts of three kinds of aluminum: primary aluminum ingot (A), secondary aluminum ingot (B), and a mix aluminum ingot (C). For this purpose, a life cycle assessment model is developed based on a damage-oriented approach, with a reference flow of 500 kg for each unit process. The results reveal that model A exhibits the highest impacts across all categories, while model B is intermediate, and model C ranks as the most environmentally friendly option. Interestingly, despite model B being the most environmentally appealing option overall, it is found to release the highest amounts of fluoride, BTEX, and VOC as air emissions compared to models A and C. Ultimately, model B, or mixed aluminum, emerges as the preferred choice due to several factors, including energy savings, low refining requirements, and reduced demand for specialized landfill operations, particularly relevant in the context of Iran as a developing country. The study further explores this comparison using Entropy and ELECTRE methods.
