It’s an outhouse, but it’s far from rustic, and it isn’t a hole in the ground. Lilypons Water Gardens uses a high-tech composting toilet system that requires no water and produces nitrogen-rich organic fertilizer.
Before you wrinkle your nose, it is entirely odor-free (unlike porta-potties) and the composting toilet process is completely safe.
In fact, it is more safe and less polluting than a traditional sewage treatment plant, where toxic substances from factories and homes enter the system along with human waste. The sludge produced by sewage treatment plants is used as fertilizer in spite of the fact that some of the toxic substances have not been removed. The composting toilet, on the other hand, produces fertilizer that is natural and free of chemical toxins.
