In a spacecraft, supplies are scarce, precisely. Therefore, in the International Space Station, the urine is recycled through a complex process, and once again becomes water. More solid waste to be brought back to Earth because of eject,can freeze and form small meteorites. In the case of space shuttles, are introduced into capsules and expelled in containers that burn upon entering Earth's atmosphere.
