Enhancing energy efficiency in aluminum recycling necessitates consideration not only of the quantity of material recycled but also of the quality of the scrap introduced into the process. This study assesses the impact of scrap condition on the overall energy demand of secondary aluminum production. A scenario-based evaluation was conducted using a combined mass-balance and energy-calculation framework to estimate the energy required to produce 1 metric ton of usable secondary aluminum. The analysis accounts for variations in contamination levels, alloy compatibility, and net process yield. Three representative scrap scenarios were examined: clean production scrap, mixed medium-quality scrap, and contaminated or alloy-incompatible scrap. The findings indicate that lower scrap quality results in increased energy demand due to the necessity for additional material input and processing effort to achieve the same final output. The estimated total energy requirements were 9.24 GJ/t, 10.72 GJ/t, and 13.38 GJ/t for the three scenarios, respectively. Although energy consumption increases as scrap quality decreases, all scenarios remain significantly below the primary aluminum benchmark of 186 GJ/t. The evaluation also reveals that remelting yield is the most influential parameter affecting total energy intensity. Overall, the findings underscore that the energy benefits of aluminum recycling are strongly associated with cleaner, better-sorted, and more compatible scrap streams.
