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 bag-lined container
-
A drying material such as coconut coir or animal bedding absorbs moisture and prevents odors
This process keeps the toilet dry, hygienic, and odor-free.
Frequently Asked Questions
Why doesn’t a composting toilet smell?
Odors occur when liquids and solids mix. By separating them and drying the solids with litter material, the system 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.
What litter material should I use?
Recommended options include:
-
Coconut coir
-
Small animal bedding
-
Other absorbent natural litter materials
Do I need a fan?
Due to the compact size and frequent emptying cycles, the Origin S does not require a fan.
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 dog waste bag or diaper 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.
