Airplane toilets use an active vacuum instead of a passive siphon, and they are therefore called vacuum toilets. When you flush, it opens a valve in the sewer line, and the vacuum in the line sucks the contents out of the bowl and into a tank.
If it is overloaded or not taken care of, a composting toilet can also draw flies or smell bad. If designed and operated properly, composting toilets are clean, odor-free and will kill the pathogens in human excrement that spread disease while creating fertilizer and saving a lot of water.nother benefit of composting toilets is that they use little or no water. By comparison, a normal toilet adds up to 5 gallons of pure drinking water to an ounce or so of waste so it can be flushed into an expensive septic or sewer system, where it is treated.
