The Technology: from industrial waste to semiconductor-grade materials.
Five elements, five recovery routes — each demonstrated at pilot scale and targeting TRL 6–7, from feedstock characterisation through to refined, semiconductor-grade output.
Five elements, five recovery routes.
All routes targeting TRL 6 – 7Gallium
Recovered through a holistic valorisation flowsheet that also yields pig iron, alumina hydrate and recycled soda — turning Europe's most-landfilled industrial by-product into a strategic raw material.
Germanium
Mechanical separation of Ge-rich glass fibres, followed by pressure leaching and ion-exchange recovery — unlocking germanium from a waste stream that today is irrecoverably lost in shredding.
Indium
A three-stage route — drossing concentration, hydrometallurgical extraction, electro-refining — produces 4N indium ready for InP wafer manufacturing. A parallel patent-pending process recycles InP production waste safely.
Antimony
Acidic leaching, selective Sb₂O₃·2SbOCl precipitation and chloride removal yield semiconductor-grade Sb₂O₃, with parallel bismuth recovery as a co-product — making the route economically robust.
Arsenic
A novel deep-eutectic-solvent electrowinning route safely converts arsenic-bearing hazardous waste into 99% pure As₂O₃, fed back into GaAs wafer production — transforming a chronic liability into a strategic feedstock.
