+ Common misconceptions, Technology, Transportation: Society :: Lists :: Knowledge
  * Toilet waste is never intentionally dumped overboard from an aircraft. All waste is collected in tanks which are emptied on the ground by special toilet waste vehicles. A vacuum is used to allow the toilet to be flushed with less water and because plumbing cannot rely on gravity alone in an aircraft in motion. The infamous blue ice is caused by accidental leakages from the waste tank.

Waste material
* Some waste materials contain water
  - produce during respiration
* provide sources.
