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,

Oxygen In The Mix: Is Oxic Microbial Electrosynthesis A Potential Alternative For Biomass Production?

ChemElectroChem, Volume 11, Issue 20, October 16, 2024.
Oxic microbial electrosynthesis (oMES) enables the conversion of renewable electricity and oxic industrial CO2‐streams into biomass by cultivating aerobic, autotrophic hydrogen‐oxidizing bacteria. This article presents the most promising candidates for oMES, discusses their biomass productivity and energy efficiency, and outlines research gaps to bring
