But this article from 1990 (may be outdated) states that a misunderstanding of the public is thinking that scrap mostly comes from old devices or planes. But these types of things last long and don't get recycled enough to provide enough volume. This seems to say that the bulk of scrap comes as a byproduct of the smelting process:
The following article from 2004 however says that recycled Ti comes from 10% old scrap (old recycled parts we normally think of as recycled metal) and 90% "new scrap" which is partly wasted Ti generated when making parts. For example in 2004, the aerospace industry used 12000t of Ti but wasted 10000t of that.
My Apple Card just expired and they sent a package to send back the old one when giving me the new one. Would be pretty neat to know they are being remade into watches.
