The article describes a new technique developed to measure the sustainability of recycling and finding the inefficiency happening in the metal recycling process, something that current life cycle assessment (LCA) methods cannot calculate. Recycled light metals are particularly susceptible to contamination. Thus, manufacturers have to apply high-purity raw material to dilute the contaminants and produce alloys of the required standards. On the other hand, to overcome the limitations of current LCA methods, a thermodynamic life-cycle analysis to light metal recycling is applied.
