do commercial airplanes dump their toilet waste into the atmosphere?

Question

i've heard they do....if so, it is pretty cool..

Answer 1

No,
It works similar to the lavatory on a train, bus or RV. The toilet flushes using limited water, in that water is not only heavy, but in short supply while airborne. The waste is stored in a steel tank.
When it is landed, after the passengers disembark, a small tank truck with a hose is connected to a drain outside the plane (which is connected to the waste tank in the plane), and uses suction to remove the waste. Every now and then the tank itself needs to be cleaned, but not often in that it is treated stainless steel.
This is usually when the lavatories are cleaned, the rest of the cabin is cleaned, the galley is restocked, and the plane is refuled as well.

This usually happens in the hangar, but will sometimes happen at the gate if they need the plane in a short time, or if it is a brief stop during a long flight.

Because of lower ticket fares, the turnover time with aircraft equipment is much shorter than it used to be, so you might just see the litttle truck with the hose pull up outside the gate and hook to your plane.

Answer 2

No, they do not. Whoever told you that was lying.

They have specific people who clean the planes before and after each flight. Those people also have to empty the toilets too. To do this, they hook a hose up to the septic tank on the plane, turn a nozzle, and the tank is emptied out into a truck. Where that truck disposes of the waste, I don't even want to know.

Answer 3

No, by federal mandate it is now atomized through the jet engines too help supplement the thinning ozone layer.
