Recycling of Spent Cathode Carbon from Aluminum Electrolysis: Detoxification Approaches, Resource Utilization, and Environmental Perspectives

ChemElectroChem, Volume 13, Issue 1, January 2026.
This review outlines the recycling of spent cathode carbon from aluminum electrolysis. Detoxification strategies, including molten salt roasting and ultrasonic‐assisted leaching, are depicted as effective approaches for removing hazardous components. The recovered carbon is further directed toward resource utilization, such as in lithium‐ and carbon ...
