How does a dry toilet work?


Almost all of us have someone in our circle of friends who has converted a van with which they want to explore the big, wide world. It is often popular with couples, but there are also people who are traveling alone and watch the sunset with an exciting book in hand. 

Vanlife has developed rapidly as the travel trend of recent years and the vanlife scene is growing many times over every day. Countless impressive pictures and videos can be found on social media, among other things, and it is difficult to resist not getting lost in your thoughts.

An important question that every van enthusiast must grapple with is how they want to do their business on the go. Since converting a van can be quite expensive, it is important to find a solution that is both affordable and functional for your travels.
In this blog we will introduce you to the dry composting toilet – better known as TTT.


What is a dry composting toilet?

A dry composting toilet is a non-flushing toilet in which the faeces are collected in a designated container and strictly separated from the urine. In places that have no connection to a public sewage system, the dry separating toilet is a low-odour, economical and ecological alternative to the chemical toilet.

The excretions are then mostly biologically useful as fertilizer. Among other things, drinking water is saved and sewage treatment plants and landfills are relieved. In this way, every camper can personally contribute to protecting the environment and has a good feeling afterwards.

How is the dry composting toilet structured?

The classic dry composting toilet consists of three components: the separating insert, the solids container and the urine canister . Other accessories include, for example, compostable bags and grit for the solids to be perfectly equipped for the upcoming trip with your van.

In the following you can see the structure of a dry composting toilet with its individual parts.

(1) Separator insert

The separator insert is there to separate the faeces from the urine. A suitable shape is important inorder to have the necessary comfort. We tested seven different prototypes until we and the numerous test subjects were satisfied with the result.

For maintenance, the divider can be removed from the box and rinsed off. For cleaning, we recommend the use of ecologically degradable cleaning agents.

Tip: The divider insert can be removed from the box and cleaned at any time!

(2) solids container

The solid container ensures that the faecesis collected separately from the urine. There is a bag in the container, which is disposed of and replaced depending on the frequency of use. In addition, hemp litter, for example, is added to the faeces, which prevents unpleasant odorsand binds moisture. The hemp litter is absorbent and the mixture of faeces and litter also makes it easier to compost the excretions.

The solids container should also be cleaned at regular intervals to maintain hygiene. For cleaning, we also recommend ecologically degradable cleaning agents.
The solids can then be composted. Here you should make sure that there is sufficient composting before the soil comes back to bed.

Tip: Make sure there is sufficient composting and regularly change the bags in the container!

urine canister

The last important component of the dry composting toilet is the urine canister. As the name suggests, the urine ends up there separately from the solids.

However, a dry toilet is not designed to store the urine in the canister for a long time. This is usually emptied every 2-3 days so that unpleasant odors cannot form in the first place.

Tip: Urine can be diluted with water at a ratio of 1:10 and used to water the garden!


Now it is important to know how the dry composting toilet works and what you should pay particular attention to when using it.


How does the dry composting toilet work?

How a dry composting toilet works is almost self-explanatory. Below you will find step-by-step instructions for use.

  • Simply fold up the dividing insert and fill the faeces container with a tear-resistant and compostable bag. Handful of hemp litter in - ready, go!
  • Just sit on it and you can start like on the normal toilet
  • Dispose of the toilet paper in the waste container or separately
  • Sprinkle the solid legacies with the odor-binding hemp litter

It is important to take care when disposing of the solids and urine that it is done in the designated places. Each of you ensures that the seats are protected from the pedal mine chaos. In the past, this has increasingly led to prohibition signs and to the annoyance of residents and authorities.
