I am currently renovating my apartment in Söder in Stockholm. It's an old 50s building with blåbetong in non-load-bearing walls.
I am now going to tear down a wall, create a new door opening, and close off two doors. I live on the 14th floor and would prefer to minimize material removal as much as possible and wonder if it is a bad idea to close off the doors by reusing the concrete. Is it better/easier to take the concrete to the recycling center and use studs and drywall?

If you get the chance to get rid of blåbetong, I would definitely do so. The exception might be if the apartment has well under 100 bq on the radon test.
If you're going to frame and plaster the hole, you should consider plastering the entire wall to avoid movements.
I would have bricked it up with lecablock.

Then I would have removed it completely, but keep in mind that if you have a wall that is not made of blocks but entirely cast in lightweight concrete, it is probably not blåbetong even if it has a light lead blue tint. However, if no radon measurement has been done, it might be worth being preventive since it is clearly a disadvantage in a potential future sale to have high radon levels. If you are sure that it is blåbetong, it might be worth actually measuring the radiation if you decide to keep it. I've heard of people being advised not to have the bed against the wall because the radiation was too high.
