Abstract: The benefit of knowing the exact chemical composition of metal scrap plays a significant role from metallurgical point of view in recycling processes. Thus, the focus of this paper is to identify opportunities for more efficient scrap management, in order to minimize quality loses and primary material consumption during recycling. By moving to compositionally closer recycling loops, higher recycling values by reducing the need for primary metal and alloying elements addition, can be achieved. A Life Cycle Assessment (LCA) was performed, focusing on aluminium scrap, in order to validate, estimate and compare the environmental impact of different recycling options and the effect of scrap separation strategies. Furthermore, a metric to compare the ‘quality’ in terms of recyclability of the various metal flows is proposed.
