“Composting toilets use the natural processes of decomposition and evaporation to recycle human waste.
Waste entering the toilets is over 90% water, which is evaporated and carried back to the atmosphere through the vent system. The small amount of remaining solid material is converted to useful fertilizing soil by natural decomposition.
This natural process, essentially the same as in your garden composter, is enhanced in commercial composting toilets by manipulating the environment in the composting chamber.
The correct balance between oxygen, moisture, heat and organic material is needed to ensure a rich environment for the aerobic bacteria that transform the waste into fertilizing soil. This ensures odor-free operation and complete decomposition of waste…”
