#MIT develops new way to recover critical metals from #EWaste
A multi-step process could produce 1.2 kilograms per day, but its viability depends on expanding #recycling efforts.
Elizabeth A. Thomson, November 24, 2025
"MIT researchers have developed a new, efficient way to recycle #gallium, #indium, and potentially other critical metals key to modern electronics from e-waste like discarded computer screens. The process could also be applied to waste streams from companies that create products containing these metals.
" 'Once optimized, our process could recover 1.2 kilograms of these metals per day,' says Antoine Allanore, a professor of metallurgy in the Department of Materials Science and Engineering. He notes, however, that this can only happen if a great deal of e-waste is recycled, and currently there are no large-scale efforts to that end. The recycling rate for gallium and indium from e-waste is currently close to 0 percent.
"The work is important because gallium and indium are listed as critical metals by the United States and the European Union. That’s because they are only produced as byproducts from the #mining of other metals like zinc and aluminum, and those mining operations, in turn, are dominated by only a few countries, including China.
"For many reasons, it doesn’t make economic sense to open new zinc and aluminum mines solely for these byproducts, says Allanore. 'Can we instead recycle and recover these two critical metals from e-waste?'
"He and colleagues have developed a multi-step process to do just that. These steps range from first physically removing #LED chips and other sources of the metals from the e-waste, to exposing them to high temperatures to liberate chemical components. Many of these steps are familiar to industry."

Forschende der ETH Zürich zeigen, wie sich #CO2 und #Wasserstoff effizienter zu #Methanol umwandeln lassen.
Isolierte #Indium-Atome auf einer #Hafniumoxid-Oberfläche steigern die Produktion um 70 Prozent. Methanol gilt als gut speicherbarer E#nergieträger und kann etwa in #Schiffsmotoren genutzt werden. Das Verfahren ist aufwendig, liefert aber präzisere Einblicke in Reaktionsmechanismen und könnte die #CO2-neutrale Herstellung verbessern.
