It is hard to guess exactly how much space junk is in Earth’s orbit, but the European Space Agency estimated there was more than 8,500 tonnes of it in 2019. Still others have gone out to explore space. That means if you added all of that junk together, it would equal around 100 space shuttles. As you mentioned, a couple of its nine methods of dealing with space junk could really just be grouped into the general theme of, stop putting more up there (deorbit your crap at end of mission). It really had little to do with "9 ways of dealing with space junk," and was more along the lines of "9 things that are kind of related that we want to talk about."
But, a lot of the things that have been sent are still in orbit. A lot of things have gone up.
NASA has been dealing with the space junk … Their idea is called E-DeOrbit . On the other hand, the European Space agency in 2014 had publicly suggested a completely different kind of mission in order to deal with this chaos of space debris. An effort to clean up space of debris from old rocket launches not only helps astronauts but everyone else back on Earth, a British engineer leading tests to clear space junk has revealed. It is a machine that they plan to send in the space.
Some have come back to Earth.
They landed, or burned up in the atmosphere. The other 20% need dealing with as a matter of urgency – and that’s where a recycling facility in space could help.
While there have been numerous ideas put forward for cleaning up the massive amounts of space trash, a new concept may …
The thing is, we continue to contribute to space debris even as we ponder how to resolve it.

Space debris (also known as space junk, space pollution, space waste, space trash, junk sats, or space garbage) is a term for defunct human-made objects in space—principally in Earth orbit—which no longer serve a useful function. Credit: NASA: We have been going into space for almost 50 years. This can include nonfunctional spacecraft, abandoned launch vehicle stages, mission-related debris and fragmentation debris. Recycling in space. The term “space debris” refers to defunct human-made objects, relics left over from activities dating back to the early days of the space age. Some have gone to other worlds.
