Leakage safety
Due to the solid workmanship, the corpus is leak-proof and protects against unpleasant mishaps on the road.

The Trelino® Evo M is a stable, robust and insensitive and dry separation toilet that accompanies you everywhere.

A fan can be installed for even faster drying of the solids. The hole in the separation toilet for the fan must be drilled yourself. We recommend a step drill 1.53 inches.

The body (made of acrylonitrile butadiene styrene, ABS) and container (made of polypropylene) are made of recyclable plastic and are resistant to aqueous chemicals.

Lid attachment
The lid, which is attached to the toilet seat, has an automatic soft close feature.

Clean design with a difference!
With the Trelino® Evo M, you can choose between three colors (coming soon).

Regional production
Production is carried out exclusively in Germany, taking into account high social standards.

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.

When do I need a fan?

A fan counteracts condensation, accelerates the drying process of the solids and ensures that fragrances quickly dissolve into thin air. This makes it particularly suitable for long emptying cycles or if your Trelino® is used by several people. All Trelino® models of sizes M and L can be equipped with an optional fan. Any S model does not need a fan due to its compact dimensions and short emptying cycles. 

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.

    Love this little compost toilet!!

    I’ve been living in my van for 2 years and this is the first real toilet I have decided to try. The perks are its smaller size, not needing any electricity, and the lower price compared to the other big name compost toilets that are always mentioned. So far I absolutely love it!! There’s hardly any smell at all and I really like that it’s easy to remove/dispose of the waste. I would totally recommend this toilet to anyone if they asked!

    Great Toilet!

    I've been using the toilet on my sailboat for about 3 weeks now. I love it! It is small and light. Emptying it is easy and there is no smell if you keep it all cleaned regularly. Living on a boat, a lot of people use the same "tried and true" products. A different very expensive and popular composting toilet was recommended to me, so I bought it. It was too big, I needed a step stool to get on it, and cleaning it out was a pain. I hated it, so I sold it. I did a lot of research and went away from the "norm" and purchased the Trelino. Great price and great product! I would highly recommend it.

    Nice Unit

    Received quickly in good condition. It appears to look like good quality and will serve our requirements adequately. However it seems to more pricey than it should be.
