Dissipative Use of Critical Metals in the Aluminum Industry

摘要: To improve properties such as weldability, corrosion resistance, strength, etc. the aluminum industry, in recent years, has enhanced functionality of alloys by increasing diversity metals being used for alloying. These often include critical ones i.e. those that are geologically scarce, highly prone to supply bottleneck and/or demanded with no known substitute. A logical solution above-mentioned identifiers would be recovery these materials from finished products at their end life. Unfortunately, yield metals, on recovery, is too low feasible economic and therefore they dissipatively lost. This work quantifies impacts losses using material flow analysis life-cycle assessment order suggest best practices minimize impacts. Results show circular economy strategies can effective mitigating criticality risk industry.
