Centralized Composting Systems Without Water

There is another type of central composting toilet and another without water. Waterless composting toilets also constitute a conventional toilet seat attached to a waste disposal system.

Waste is drawn from the toilet through a tube into a composting system. This type of centralized composting system toilet almost always maintains the airflow in the toilet. The airflow helps move waste through the tube.

And this airflow also helps to move unpleasant odors. These toilets are particularly useful in areas where there is a water shortage. These toilets are also valuable for RVs, boats, and mobile homes, as they do not require a constant supply of water.

How It Works

Composting toilets depends on the natural process of decomposition and evaporation of waste during the recycling of human waste. Waste in toilets represents more than 90% of water.

When it evaporates, it is returned to the atmosphere by a ventilation system. The remaining solid material is transformed into fertilizer by natural decomposition.

Composting toilets are not challenging to install, even for maintenance personnel. Most composting toilets available on the market can be installed by connecting two-floor supports.

Some models of composting toilets do not require the use of filling material. The use of fillers in a toilet like this can lead to its deterioration.
