Recent Advances in Recycling of Copper‐Based Waste Materials: A Critical Review

cMat, Volume 2, Issue 2, June 2025.
ABSTRACT Copper plays a crucial role in the civilization of our lives. This review examines the flow of copper from the mining of ores to the end‐of‐life product, with particular emphasis on the recovery and re‐functionalization of copper and copper‐containing wastes. Beginning with the analysis of the global copper market, reserves, supply, and demand,

Lanmodulin‐Decorated Microbes for Efficient Lanthanide Recovery

Advanced Materials, Volume 37, Issue 10, March 12, 2025.
Bio‐scaffolded lanmodulin (LanM) on E. coli is developed as a simple, effective material for repeated capture and release of rare earth elements (REEs). Over 80% of four REE cations are captured, even in the presence of excess competitive ions. The material can be employed in a filtration flow‐through system with a capture capacity of 11.8 ± 0.9 mg g−1

Recycling of Critical Metals from Light‐Emitting Diodes

Chemie Ingenieur Technik, Volume 97, Issue 1-2, Page 110-115, February 2025.
The new process for recovering the critical metals indium and lutetium from light‐emitting diodes uses polyvinyl chloride (PVC) or PVC waste as a cheap chlorine source for the chlorination of indium for evaporation. The residue was leached out and the filtrate was used for liquid‐liquid extraction to recover lutetium, as a test‐of‐concept study ...
