How to get to 10 trillion people in this solar system?

1) where does the waste go. if you push it back out into space, it
would be in the same orbit eventually it would be too clutter with
waste for safe travel. if it were put into other orbits it would
eventually be in someone elses way.

2) at the rate of expansion of the human race it would only take a
few centuries of this kind of waste to use up all the resourses of
our solar system.
