Where does stool on planes go?

It gets stuck in the clouds and turns into poo rain , I read a paper on it

Airplane toilet waste is either like a closed waste system or vacuum waste system. Like you said, it's pretty much contained in the plane until it lands. Then the ground crew accesses the valve for the waste (it's outside the plane) and takes it out.

Every commercial flight can generate up to 70 liters (18 gal) of human waste. Here’s what happens: 1. Vacuum toilets use suction—not water—saving ~80% of weight. 2. Waste is stored in sealed tanks below the aircraft. 3. It’s suctioned out after landing by ground crews. 4. No, it's never dumped mid-air (that’s a myth!). Planes carry millions of liters of waste globally each day.
