Our biotechnological process enables the recovery of critical metals (Ga, Ger, In) at competitive prices. SideroGaIn offers an economically attractive alternative to primary raw material extraction. SideroGaIn uses biomolecules instead of conventional chemicals. Imitating natural process makes the approach particularly selective and environmentally friendly. Our Biomolecules (so called siderophores) are reusable over many cycles without losing their functionality, which reduces resource and chemical consumption. We offer the installation of entire plants and trade intermediate raw materials.
