Aluminium production has one of the most significant energy consumption

• , with rates ranging from 25% to 85% worldwide [3]. In the last decade, interest in the circular economy issues has increased almost a hundredfold [5], accompanied by research and widespread awareness. However, circular economy is still a relatively new concept. It has been embraced as a concept based on
