Kerkam has been developing and building world travel vehicles for years and is intensively engaged in the question of which systems really work in everyday life.
In a recent video, they compare different toilet systems –
in the context of world travel vehicles and from their daily practice.
The following will be shown:
Composting toilet
dry composting toilet
Sweat toilet
Macerator/blackwater toilet
What quickly becomes clear and is clearly visible in the video:
The systems are working.
But they differ significantly in everyday life.
Differences become very clear in:
comfort
Odor
Handling
In the end, Kerkam makes a clear decision:
The SETRENLO® composting toilet is the preferred solution.

Why?
Not because of a single feature. But because of the combination:
The workmanship and material quality are clearly emphasized – moving away from simple plastic towards a significantly higher quality overall impression.
At the same time, it becomes clear that no litter is necessary and the effort in everyday life is noticeably reduced.
The integrated venting creates a negative pressure, so the system is described as odorless during operation.
This reduced effort is repeatedly highlighted in the video as a crucial advantage in everyday life.
One point becomes particularly clear:
The less you have to think about it, the better it works in everyday life. That's the crucial difference.
