I just imagine that once you do work at such scales, and with such strange materials and results, then the "waste products" of that work would be just as weird.
Also, would black holes not be considered "broken space" themselves?

Even that is really an anthropomorphization. They don't "spread". They don't "damage" the space around them. They don't leave behind anything as they pass through space. They aren't having the effects that people imagine when they think about "pollution".
