Recycling
The decarbonization and digitization of the economy is accompanied by a sharp increase in the consumption of metals (lithium, cobalt, copper, niobium, etc.), as well as by an important production of waste electrical and electronic equipment (WEEE).
As part of the SCARCE joint laboratory (CEA/NTU Singapour), multiple processes have been developed to recycle strategic metals from WEEE, in particular those with low recycling rates (tantalum, rare earths, etc.). The use of artificial intelligence coupled with multi-energy X-ray analysis has enabled the development of a unique sorting tool, capable of enriching waste streams with strategic metals by sorting electronic components from WEEE.
The development of hydrometallurgical metal purification processes is facilitated by the laboratory’s microfluidic platform, which combines infrared and X-ray fluorescence spectroscopy to study separation processes (liquid-liquid extraction, ion exchange resins, membrane processes, etc.).
