What would happen if we built a giant smokestack that was tall enough to be in space, and started burning a bunch of stuff on the ground?

Might be a silly question. Still curious just the same.

What would happen to the smoke/pollution if we started burning a bunch of stuff here on earth but had all of the nastiness float up through a giant smokestack some distance off into space? Would it dissipate or just hang out there, ready to poison us at some later date?

Thanks for any answers!

Assuming you can build the stack in a way that it's stable. And then assuming that you could find a way to make sure everything goes all the way to the top and you could actually eject stuff into space...

Earth's gravity would just pull all that crap back into the upper atmosphere.
