This cargo is stored throughout the flight. In some aircraft, disposal of solid waste is due to the vacuum that sucks them out of the toilet. Residues in this case, are washed with a little water.

There are also sewer system closed type, which operate on the principle of recycling the liquid. In flight after flushing solid waste is filtered. The resulting liquid is sent again to re-wash. At the same time the tank penetrate chemicals for deodorizing and disinfecting liquid.
