No Titanium – No Modern Aviation
Planes are essential for many people. So titanium is, too, as it provides stability for the undercarriage, engines, fuselage and
wings. The world would be a much smaller place without this metal. However, natural reserves of the material are finite and
are expected to last another 137 years. REMONDIS is thinking ahead and developing processes to return titanium to production
