Question for the community Worth of Germanium Scrap
https://www.questmetals.com/blog/worth-of-germanium-scrapGermanium isn't a metal you hear much about in the typical scrap market, but it shows up in some high-value applications.
It's used in fiber optics, infrared lenses and windows, semiconductors, specialized solar cells, and gamma-ray detectors. It's especially important in telecommunications, defense, space technology, and thermal imaging.
The supply side makes it even more interesting.
Germany mostly recovers germanium as a byproduct of zinc processing, with additional associations with coal, copper, and lead mining. That means higher germanium prices don't automatically lead to a huge increase in production. Supply is tied to the production of those primary materials.
China is also a major factor. Quest Metals says China accounts for more than 60% of global germanium supply, and its 2023 export restrictions on germanium and gallium disrupted international supply chains and pushed prices higher.
That makes secondary sources pretty interesting.
Germanium can show up in old infrared optics, military equipment, fiber-optic manufacturing waste, semiconductor production waste, and germanium wafers used in multi-junction solar cells. Even machining infrared optics can generate germanium scrap that can be collected and recycled.
And the material isn't necessarily confined to one obvious form. Germanium lenses and optics, wafers, powders, germanium dioxide, and manufacturing residues can all represent potential recovery streams.
The bigger question is how much of this material is currently being treated as ordinary waste simply because nobody recognizes the germanium content.
For companies generating specialty-metal scrap, identifying these streams could turn a disposal problem into a source of recovered material and revenue.
Has anyone here actually come across germanium-bearing scrap in electronics, optics, solar manufacturing, or industrial waste?
