How a Composting Toilet Works
A composting toilet uses a urine-diverting separation system to keep liquids and solids apart.
-
The separator insert directs urine into the canister
-
Solids are collected in a container lined with a bag
-
A drying material such as coconut coir or animal bedding absorbs moisture and prevents odor
This process keeps the toilet dry, sanitary, and smell-free.
Frequently Asked Questions
Why don’t composting toilets smell?
Odors occur when liquids and solids mix. By separating them and drying the solids with litter material, the Evo L prevents odor buildup.
Do I need to change the bag after every use?
No. The solids container can hold multiple uses before needing to be emptied, depending on usage and litter material.
What litter material should I use?
Recommended options include:
-
Coconut coir
-
Small animal bedding
-
Other absorbent natural litter materials
Do I need a fan?
The Evo L works without a fan, but installing one can speed up drying cycles and reduce condensation, especially with multiple users.
How do I dispose of the waste?
-
Urine: Pour into a toilet connected to a sewer system
-
Solids: Dispose of the bag similarly to a diaper or dog waste bag according to local regulations
How do I clean the toilet?
Cleaning is simple:
-
Wipe the seat and bowl as needed
-
Empty and rinse the urine container every few days
-
Remove and replace the solids bag when full
Cleaning solutions such as vinegar, citric acid, or natural cleaners work well.
