Odor neutrality
The separation and drying function of the toilet prevents unpleasant smells.

By dispensing with chemicals and water, the Trelino® Evo L is environmentally friendly and preserves natural resources.

Without water and chemicals, the Trelino® Evo L offers the freedom to travel independently of disposal stations.

Hygiene and cleanliness
Individually removable containers allow separate emptying and easy cleaning.

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

The Trelino® Evo L 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 L, you can choose between two colors (white & dark grey).

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.

Do I need a fan?

For other types of toilets, you might think about using 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.

    First Impressions are Good but Ready to Road Test

    First off, the customer service has been excellent. Before purchasing, I submitted a couple of questions via chat and got answers within 24 hours. Once I ordered, I made a mistake and didn’t apply my $30 promo code so sent a chat asking if it was possible to get a credit after the fact. It was applied right away.

    We’d been contemplating retrofitting a composting toilet in our commercially built out van for a couple of years but all the options were too large for the space we had to work with…until Trelino came along. The large EVO just fits our space and we love the simplicity of this toilet over the many others we looked into.

    I removed the previous toilet, capped off the drain to the black tank and built a frame to hold the Trelino in place while in transit. Down the road, I may try to figure out how to drain the liquids into the black tank as an option. (It would be great if the Trelino engineers developed a urine holding canister with a valve that could be used for this purpose).

    We kept the Trelino in the house for a week to test it out. Both my wife and I found it easy to use and once we used the proper litter (we started with wood pellets because that's what we had and would not recommend), there was no smell. We’re home composters so the concept of properly balancing wet material with dry material to avoid smells is easy for us.

    As noted, the female anatomy requires some adjusting to properly “hit the targets” so to speak but she didn’t find it difficult and that was one of her main concerns with a composting toilet.

    The four stars are only because we haven’t had a chance to to test it on the road for a sustained period of time but (and I never thought these words would come out of my mouth), we’re excited to put this toilet to the test.

    Expensive (Great CS)

    First toliet arrived broken in a few spots. Customer service was quick to get a new one shipped out once I sent the broken one back. My main complaint is the high cost for such thin material. Removing the top, or opening the lid is a bit of a challenge due to the tiny little lip they give you. The separation portion works great. I just think for what it is, it could be priced better. I'd say it's a 3 star item with 5 star customer service.

    Great Portable Toilet

    I am thrilled with my new is comfortable, light,,portable…all things I love in a toilet

    Tammy (United States)
    Great composting toilet

    I’ve tried out a few different composting toilets, and this one is just as good as the $1,000 ones! In my opinion it looks sleeker too. Definitely a good purchase
