About the project.
InGaGe recovers five strategic semiconductor raw materials from European industrial and end-of-life waste streams — closing the loop from bauxite residue to wafer, inside Europe.
Semiconductors power the green and digital transition — but Europe depends almost entirely on imports of the strategic metals that make them possible. InGaGe closes that gap.
The project develops and demonstrates integrated processes for the recovery of Gallium from bauxite residue and crude-Ga production waste, Indium from zinc-smelting alloys, Germanium from optical cables and LEDs, Antimony from copper processing residues, and Arsenic from GaAs wafer waste and legacy metallurgical dust.
Beyond extraction, InGaGe innovates the downstream value chain itself: a novel plasma refining method delivers ultra-pure gallium, while a scaled HTVPE reactor produces 2-inch GaN wafers from recovered metal. Recovered indium and gallium are validated in industrial InP and GaAs wafer production at Freiberger Compound Materials — closing the loop from waste back to wafer.
The result is a sovereign, sustainable, cost-competitive European semiconductor value chain — aligned with the Critical Raw Materials Act and the European Green Deal.
