Dr. A. Fysikopoulos, Dr. G. Pashos and Dr. F. Tzevelekou attended on 1 & 2 December 2021 the two-day online Future Aluminium Forum Digital. Over 200 attendees were informed on the latest developments surrounding Industry 4.0 in the aluminium manufacturing process. Key applications of new Digitalization tools were presented that enable Process Optimization and also facilitate transition to Sustainable Manufacturing and Circular Economy. Energy efficiency practices that lead to reduced production costs, stricter legislations pushing the industrial sector to use cleaner energy sources and move towards CO₂ neutrality and finally the fact that future end users will demand a “clean/green” product, manufactured with zero carbon emissions consist vital challenges of our times.
