How does a composting toilet work?

A separating compost toilet has three main pieces: separating insert, urine canister, and a solids container. All of these work together to make sure your camping toilet is dry and smell free! The separating insert funnels the urine into the canister, while the solids are kept separate in their own container lined with a bag and a drying litter material. To learn more, you can check out our page:  "How Does a Composting Toilet Work?". 

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. Women may need to sit up straighter or closer to the front. For more tips on this, you can read our article here. 

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?

Nope! Trelinos are urine diverting toilets which keep everything as dry and smell free as possible. As long as you are using a good litter material to cover your solids, they should be dried out and have no smell which means you don’t have to empty the bags after each go! Depending on the size of your Trelino®, the bags hold between 3 and 12 number 2’s.

 

Which litter / cover material should I use to dry the solids?

There are a variety of different sprinkles you can use in your solids container.
We recommend small animal litter or coconut coir. While these are our top suggestions, there are still numerous alternatives that our customers use. For more detail on these options, you can read our page "Consider Your Litter".

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. Due to its compact dimensions and short emptying cycles, the small Trelino® options do not need a fan.

What happens when I have diarrhea?

Diarrhea is not a problem when using a composting toilet. Actually, having one so close should help you in those emergencies. You only need to sprinkle on more litter after the fact to help absorb any extra liquid.

Where do I dispose of the contents?

The urine canister and solids container can be emptied independently of each other. The urine can easily be disposed of in a toilet connected to the sewer system. Just pour and flush.  Diluted, it is also suitable as fertilizer for your home garden. The bag with the solids can be disposed of similarly to a diaper or dog poo bag. We recommend checking local regulations for disposal guidelines. Conditionally, composting is also possible. 

Which bags should I use to line the solids container?

You can start by using the 10 bags that we include in your Trelino® order. These are thicker bags made from recycled materials that will make sure your waste stays in the bag and doesn’t leak through. You can also use bags made from compostable material if you are looking to compost your waste. 

How do I clean a composting toilet?

Cleaning a composting toilet is as simple as its use. You can use diluted vinegar, citric acid, or even microorganisms to clean your Trelino®. There are just 3 easy cleans that your toilet would need. 1) Spray and wipe down the toilet “bowl” and seat as needed 2) Every 2-3 days empty then rinse out the urine canister with your cleaning solution. 3) When full, just lift up the bag in the solids container.

If you need a toilet on the go, this is the one.

It works exactly as described. No stink! Light weight. I couldn’t be happier with this toilet.

Pretty Great.

Overall, I think these things are great and customer service is very responsive. I would have given it five stars except this review is after having to have it replaced because the original cracked after just a few uses. But they replaced basically with no questions asked. I just sent them an email with some pics and they got back to me right away. I had a new toilet within a week. Thanks.

It works

it is functional as described and small footprint for a van - seems pretty sturdy and should last just based on the first month of experience only.

The can could be much better quality for the price, and the pee jug has no handle on small version.

The resin for the 3 stars is pretty much solely based on the price - which is absolutely ridiculous for the materials and construction.

The price for this on CDN site should be no more than $200-$300 max, after taxes and delivery $1000 still has me shaking my head at the price i paid.

This is the one I needed

We have a rugged high clearance 4WD campervan. We had no toilet, just a shovel (good in wild places) and coffee can (night use and scary). The Trevilino, while expensive, has been a game-changer. It fits between the front seat. It does not look like a toilet. It does not smell. Only tried the poo part once, just to try it out. It works fine. I used sawdust/wood shavings and biodegradable bags. Perfect to bury or dispose in trash or outhouse. Urine is simple. I use a spray bottle of water after using to clean the separator. Empty every day to two. Holds a lot. Great for night use and for where there are no facilities. Glad I bought this!

Disappointed

Purchased Trelino Origin S toilet with high expectations. After sitting on toilet, realized low height was uncomfortable to sit on. Returned toilet to fulfillment center according to refund instructions. Has been over three weeks since toilet arrived at warehouse and still have not received refund confirmation. I also felt quality was just ok for price.

Toilets conforme à nos attentes

Toilet conforms to our expectations, except for 2 small details that we are going to modify: The wooden lid is not protected. For easier maintenance, we varnished it with a clear varnish to keep the natural side of the wood which is very pretty, and we are going to fix it to the toilet because it is not practical to have to remove the cover to put it on the ground (translated to English)

Best buy for my Bulli

Brilliant

It works great and gives you so much more freedom and liberty especially if you are traveling alone and don't want to leave the van late at night for a wee.
