Into the lavatory holding tank.

As an example, a Boeing 737-700 has a holding tank that both forward and aft lavatories flush into. (Other models have one holding tank per restroom location i.e. fore, aft, middle). The holding tank is filled with blue disinfectant/detergent.

Once on the ground, the lavatory service agent empties the tank contents into a truck which is taken to a sanitary disposal location on airport.

Here is an image of the dump process

On the CRJ-200 the waste from the toilet is stored in a tank and is off loaded after landing much like an RV, waste water (grey water) from the bathroom and galley sinks is vented directly overboard through heated vents (to prevent the water from freezing) the water hits the airstream and is instantly turned into a fine mist as we are going around 400 MPH

You never said what kind of airplane.
In a military fighters they have a pilots relief tube. It's a funnel attached to a hose and is vented overboard.
On larger military A/C they have a honey bucket. The rule is, the first person to use it, cleans it.
On small private A/C there isn't a way except landing or use a empty coke bottle.
On most large commercial A/C they have a storage tank.

Waste is stored in a tank on board the aircraft and stays there until it is removed and emptied at the airport.

There have been incidents of this tank leaking; the waste mixes with the blue disinfectant in the tank and freezes when it leaks and, known as blue ice, has been known to fall through people's properties...

it truly is an hardship-free one. If the international receives too warm, we've shown that we may be able to live on it because the "Cradles of Civilization" were in warm, dry aspects. If the international receives chilly, then we've already shown that we may be able to face up to ice a lengthy time period, and that is with none "severe" technologies. If the international receives overpopulated, it really is going to, out of necessity, stability itself out. i do not imagine we want to rigidity about surviving the subsequent one hundred years. the actual question is a thanks to we save the subsequent one hundred years from transforming into the subsequent darkish Age.

the waste is first of all collected in a big container. after the flight, at the airport on the runway, when the plane is parked, it is taken inside to dump somewhere. a good question. we often do not see it.

It is placed into a holding tank just like those in an RV. When they land and service the plane it is removed.

It goes into a holding tank which is emptied at the next servicing airport.

In the plane's lav bin,as of now.But with the
rising costs they may dump it overboard.The
constipated waste might go to research labs as
meteroits.
