A system recognised for its performance.

At the heart of all our products is the “Kazuba Toilet System (Système Toilettes Kazuba)”, or STK. Patented in 2011, the STK is an autonomous, watertight, dry toilet system which works on a simple principle and with no internal moving parts.
Our system won the award for innovation in the urban planning category at the Salon des maires et des collectivités locales in France, 2010.

The STK Patented System


A principle that is both natural and original

STK technology is based on constant air flow, which allows for a reduced volume of faeces and urine, through evaporation and dehydration.
Aerobic action and gravitational separation of urine and faeces allow for odourless use.


Nature works well, we just observed how it did it. There was nothing to invent, it was already there …

Simplicity is at the heart of our approach. For the user, it’s simple: there is nothing to do (i.e. no sawdust), just use these toilets as normal. For you?
Simplicity and peace of mind are assured: no consumables and total reliability.
