Why did we choose a composting toilet?

💩
What toilet options are available for a van? What option did we choose?
After driving around Rome with a rental van trying to find a place to empty the cassette toilet, we decided we would never get one in our van. The idea was sealed when we finally found a place to dump the black water. The place was disgusting. There was human excrement everywhere and the smell was terrible 🤢. We knew we would not get a cassette toilet to our future home on wheels. Next, we started to explore options.

What options there are available?

Portable camping toilets are light, but most have all the stuff going in the same container, which might cause more smell.
Cassette toilets may only be emptied into certain marked black water emptying stations, but they cause less odor than other toilet options. The chemical capsule put in them must be changed approximately every five days. Sometimes they may become clogged with 💩 during emptying.
Composting toilets are easy to empty, but you must do it more often because they start to smell faster.
Or no toilet and only a shovel  might be a good option in nature but in cities and villages, you may have problems finding a public toilet or a bush for privacy. The plus side is that your camper will have more space for other things.

How to use the Trelino composting toilet?

First, line the 💩 container with a compostable bag. Then, open the toilet and attend to your needs. After use, add compost soil to the 💩 container and close it with a lid. When the container needs to be emptied, lift the lid of the entire toilet, empty the contents of the urine container into a natural space, and dispose of the waste container bag in the trash.
Be careful not to put wet towels in 💩 bin. They will hinder the composting process.

Cleaning tips

We clean our Trelino every time we empty it. That is, about every other day. Here’s how we do it:
  1. Rinse the pee container with water
  1. Wipe the toilet with antibacterial wipes inside and out
  1. Spray a vinegar-based detergent and wipe it off carefully with a cleaning cloth. Vinegar helps with odors.
  1. Allow all the parts to dry before putting them back in place
