What it is
Titanium metal (sponge) is the basis of high-strength, corrosion-resistant alloys for aerospace, medical implants, and chemical equipment.
Why it matters
China and Japan dominate sponge production. Russia's VSMPO-AVISMA was historically the largest aerospace supplier.
Circular challenges
Whether titanium metal re-enters the economy at end-of-life is mostly settled at the design stage. These are the recurring blockers.
Aerospace alloys are long-lived
Airframes fly for 30+ years; scrap arrives slowly and is highly alloyed, complicating reuse.
Powder-bed printing waste
Additive-manufactured titanium parts generate fine powder waste that needs careful collection to recycle safely.
Implants are permanent
Medical implants generally do not return to the supply chain.
