Composting toilet how it works

Composting toilet how it works. We’ll understand better after its definition. It is a type that works on a biological process. The process is composting, so it is called a composting toilet. Composting is done by microorganisms.

It works by delaying the waste material that is exerted on our bodies. In an economical view, it is better to use as it doesn’t require water.

There is a chamber for decay present beneath it. It stores the waste, which with time, decays and turns into carbon dioxide. The working, however, depends on the type of composting toilet you are using. Learning how it works will aid in better installation.

It simply works by storing waste. There is a chamber present beneath the toilet pedestal. This chamber stores both feces and urine closed away.

In that chamber, the microorganisms do their work. They decompose the feces and other organic materials.

Other than the decayed material. Carbon dioxide is formed from it, and so are water vapors. Other than that, toilet type is what the working depends on.

This was just what is generally done by it. They are usually used in places that are not for permanent residence. But they can be used in permanent residences too.


There are mainly two types of these toilets. They work similarly except for storage. The difference will be within the working.

The toilets are like normal ones in case of sitting. We exert feces from the body into the bowel. The work starts immediately. The wastes are separated from each other.

There is a container down according to type. The urine moves there. Storing aerobic organisms, there can be an evaporating chamber instead. Fungi, bacteria, and insects that lay waste to decay are the aerobic organisms present.

As soon as the urine enters the tank. The aerobic organisms present there start acting. They convert the waste into a liquid that contains a lot of nitrogen. This liquid boosts the evaporation process.

The solid waste is moved to another chamber. In that chamber, the aerobic organism starts breaking it into decomposed material. This happens slower because the material being broken down by the microorganism is solid. The material formed is dry.


Materials like sawdust and wood chips are absorbent carbon materials. They need to be present there as they make the decay faster and more efficient even though they are in a small amount.

All elements should stay active for working. This is to ensure that all materials are broken down. This should happen continuously. The factors like temperature and the air level should also be complete and brought into consideration.

Some types contain a manual agitator. This manual agitator provides air to the chamber. The air is provided in subtle amounts so that the oxygen level remains complete as required.

Some contain a handle connected to the chamber. You can rotate it to provide aeration and the amount of oxygen required by the chamber.

Temperature is also an important factor for aerobic organisms. The optimum temperature helps in keeping the organisms active. Some toilets even have a special electric heating system.

The electric system provides them with the optimum heat required by them for active working. Others that do not have this heater provide natural heat. This heat provided is at a level that is good for working.


There are more types, but two are the main ones.


self contained

There is only a single storage unit for both urine and feces. All parts are connected to each other. This system is much better for working in small areas or confined places.

It doesn’t require much space. It is better for double-story buildings.


In this, there is a large centralized tank. It stores all the waste. It is installed outside or under the house. This type is further divided into more.

It may depend upon the storage capacity or the flush system. It resembles normal toilets. Thus, it provides a better experience for us and is more suitable.


The working of these toilets differs from the ones we use. They do not require water. This is a better way of saving natural materials.

I encourage you to use this as you will save both water and money. They are organic and use natural methods for eradication. There is no smell from them either.

They are suitable for moveable places. They are cheaper as well.
