How does a composting toilet work?

The inner workings of a composting toilet essentially consist of three parts: separator, urine canister and solids container. The separator leads the urine into the canister, while the solids end up in a bucket with a compost bag. You can also read a more detailed version in our blog post here.

What should I pay attention to when using it?

The correct sitting position is crucial for the best possible function of a composting toilet. For anatomical reasons, this differs for women and men. 

Why does a composting toilet not smell?

Odors are caused by the mixing of solids and liquids. Separating the excreta and then drying the solids prevents undesirable aromas. 

Do I have to change/empty the plastic bag after each use?

No! The whole point of using litter as a cover material to dry out the poo is that you can use the bag for several days and only empty it once full enough. Depending on the size, the bags hold between 3 and 12 number 2s.

Where can I get the litter / cover material to dry the solids?

You will be able to buy litter from us some time early next year. Until then or otherwise you can also buy good litter material from any garden or home improvement store. Find more info on our blog post about litter here.

Do I need a fan?

For other types of toilets, you might use a fan to counteract condensation, which accelerates the drying process of the solids and ensures that fragrances quickly dissolve into thin air. This is not necessary for your Trelino® because you would use a litter material after each use which dries out the solids and removes the smell. On top of that, the emptying cycles are quite frequent so you can very quickly dispose of your bag.

What happens when I have diarrhea?

Diarrhea is not a problem when using a composting toilet. Just use more litter to compensate for the liquid.

Where do I dispose of the contents?

Urine can easily be disposed of in a toilet connected to the sewer system. Diluted, it is also suitable as fertilizer for the home garden or the raised bed on the balcony. The bag with the solids is a case for the residual waste garbage can. Conditionally, composting is also possible. The urine canister and solids container can be emptied independently of each other.

Plastic bags and composting - how do they fit together?

For us, sustainability and environmental awareness do not end with disposal - we think beyond the garbage can. That's why we use renewable, organic materials for our solid bags that can be easily composted.

How do I clean a composting toilet?

Cleaning a composting toilet is as simple as its use. The household remedy diluted vinegar concentrate has proven its worth for most of the cleaning. Read more about it in our blog post here.

What makes Trelino® so special?

Trelino® is a quality product designed to last. A high-quality composting toilet that will accompany you for many years and makes a statement against the throwaway culture. In addition, Trelino® combines optimal functionality, ease of use and high comfort behind a unique design.

    Trelino Evo S

    We we're a bit hesitant about going with a "compost" toilet, but are extremely pleased with how compact it is, how well it works (essentially no smell if you use the coconut husks in adequate amount), and relatively easy maintenance. We used to have a cassette type-this is much better. Many people are grossed out about the idea of it, but take a chance and try it. I bet you like it.

    Well made

    Have yet to actually take it for a “test ride”, but it’s a beautifully made product, sleek, compact and lightweight but very strong construction. Looking forward to camping with it this spring!

    Pretty fantastic off-grid toilet for a lady!

    Separating solids and liquids can be challenging in offgrid situations, but this little toilet makes it super easy! No smell! Very clean! Love it.

    So far everything that was promised!

    Easy to use and no smell!! I’ve only used the toilet for about a week but so far it’s great! Definitely would recommend. Note that the small, least expensive toilet sits low to ground and the seat is hard plastic.
