Is It Safe to Use Miso Paste?

If you take something into space, you have to bring it back. We don't want anyone who's driving to swoon at the wheel. Would most of these things, if they aren't given thermal protection, never survive re-entry? All you have to do is nudge them into lower orbit so they burn up. That seems to make sense to me. But I think I'm guessing the worry is if you simply nudge it, try to nudge it into lower orbit that it might hit something else on the way and cause another one of these collisionsthat then causes, you know, space.
