semiconductor raw material
production from European resources.
InGaGe recovers and refines five strategic semiconductor materials — Indium, Gallium, Germanium, Antimony and Arsenic — directly from European industrial and end-of-life waste streams. From bauxite residue to wafer, the loop closes inside Europe.

Europe makes the chips. It does not make the metals.
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, Indium from zinc-smelting alloys, Germanium from optical cables and LEDs, Antimony from copper processing residues, and Arsenic from GaAs wafer waste.
The result is a sovereign, sustainable, cost-competitive European semiconductor value chain — aligned with the Critical Raw Materials Act and the European Green Deal.
