I have no idea if there is market for core turbos. I would be surprised if they are rebuilt. They are such a tight clearance item and very close tolerances, I doubt anyone would buy to rebuild. They take a lot of abuse with the high rpm and extreme temp, so doubt you could even rebuild at end of life. Just like cv axles, china used to buy them all the time to rebuild. Now they don't, cheaper to build new.
Although I could see one use. You can make a hillbilly jet engine out of them, check youtube.
There is also videos on how they are made and apparently most pieces are one piece cast aluminum or steel.
