At this Point I would like to answer the most frequently asked questions regarding composting toilets and in response to the customer service of my-composting-toilet.com/ meinetrenntoilette.de.

General questions

How does a composting toilet work?

The composting toilet separates the liquid from the matter. Urine from stool through a designated insert.

Hence the many advantages of a composting toilet.

The principle is as follows:

For the further information read this blog article which summarises all you need to know about composting toilets.

Are composting toilets also dry toilets?

Yes, composting toilets are also dry toilets, as they do not require water. Dry toilets differ from composting toilets in that they do not necessarily separate solids and urine. Both can go into the same container.

We currently only offer separation toilets here. Because here the disposal is simple and unconventional, and usually no (chemical) additives are needed.

Can I use a composting toilet anywhere?

Yes, you can install a composting toilet anywhere wherever you can install a normal toilet.

You can even use the separating toilet in places where you can no longer use a normal toilet. Namely where there is no water supply and no sewerage system.

This is what makes the toilet unique and popular with many summer house, tiny house, weekend house, boat owners and more and more motor home owners.

You don’t need water, no chemicals and you can dispose of your waste (almost) everywhere. Because urine and solid matter are natural substances, which you could even use as fertilizer or compost.

Should I buy a composting toilet or build one myself?

That depends entirely on your preferences. We have many customers who build their own individual composting toilet with the offered separating inserts and containers. Others use the already complete composting toilets.

Meanwhile there are already a lot of finished variants. With and without composting equipment, compact ones made of plastic, designer toilets made of wood or even really great garden toilets.

Have a look around the shop, read the many user reports on camperactive.com or watch the corresponding videos.

Where and how can I dispose of the toilet matter?

The separated remains are pure urine and feces and you can dispose of both (almost) everywhere. Diluted urine can be used as fertilizer. However, please note that in this case you should use it in the case of any medication excreted in the urine.

Otherwise, simply dispose them into the sewerage system.

You can also compost the solid matter. Or simply put it in the household waste. It couldn’t be simpler.

Do I have to use a fan?

From my personal experience I would suggest using a fan. Especially if your solid is still fresh or moist, it is advisable to use a fan to remove the residual moisture.

Depending on the place of installation (garden house or mobile home) and the size of the room, you should actively ventilate with a fan. (Passive ventilation can also be used for garden houses.)

Does a dry toilet really not smell?

Right. Due to the separation of urine and solid matter, there is no formation of odors, which must be combated with chemicals, e.g. in chemical toilets (everything in one container). Usually it is the residual moisture in the solid that could cause unpleasant odors.
To prevent this from happening, you should cover the solid with a litter. Here you can use e.g. small animal litter, sawdust or bark mulch. Or you have a toilet with “under agitation” function (e.g. NaturesHead, AirHead, C-Head.) Here you only need a starting medium (e.g. a brick made of coconut fibre).

With each toilet visit the solid matter is then stirred under the solid matter already in the container and covered.
