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.
After the toilet has been used, all waste material and paper gets moved into the burn chamber by an auger. The incineration process continues until all of the waste material is gone. This process takes about 5-10 minutes for a short cycle (liquid waste) and 35- 40 minutes for long cycle. The SR5 models use propane, and the SR12 models run on propane, natural gas, or diesel.
