Why public dry toilets?
Historically, water toilets have dramatically improved the sanitary quality of cities, but they consume far too much water and cannot be installed everywhere.
Sanisphere develops more innovative and environmentally friendly sanitary solutions to meet your needs for reliable public toilets in every situation.
Smell-free, hygienic and easy to clean public toilets?
The sight of filth and foul odors, regardless of the style of toilet, make them unpleasant to use.
Sanisphere toilet cabins are hygienic, modern, and meet accessibility requirements for those with disabilities. Our toilets are designed to be clean and to be thoroughly washed.
The other challenge is to remove odors to bring maximum comfort to users. Sanisphere has developed a natural self-ventilation and filtration system. The air is aspirated by the toilet seat, then escapes through a chimney. The space is therefore permanently ventilated: there is no smell during use, or even during large flows of users.

How do Sanisphere dry toilets work?
The first technological challenge was to separate effluents from toilets, as our bodies do naturally. Separation, like waste sorting at the source, prevents odors and allows for better in-situ treatment of materials, enabling for their valorization.
Sanisphere has patented innovative technological devices of conveyor belt for urine diversion, located under the seat or under the floor of the dry toilet and operated by a pedal. On the one hand, the liquids are directed by simple gravity into a drainage circuit. On the other hand, the solid elements remain on the conveyor belt and are transported to a composting room.
Then comes the second step of Sanisphere dry toilet technology: the recovered materials are processed into humus by compost worms, bacteria, fungi and insects. Humus can then be used to fertilize green spaces, for example.

Better than Sustainable: Eternal Toilets
Sanisphere dry toilets are designed to work “forever” and without draining. The treatment of materials by the ecosystem – in particular by vermicomposting – considerably reduces the volume of compost over the years.
Technical devices that suit to your needs
Flexible, forward-looking solutions to manage urine
- A connection to the network to integrate
- Storage tanks for future valorization
- Spreading drains for more simplicity
- Dry urinals for a better welcome during high attendance
- Co-composting urinals for natural treatment solutions
A mastery of the treatment ecosystem
- A biological inoculum is added when installing toilets with detritivorous species that treat and significantly reduce the volumes of organic matter over the years
- During its annual maintenance visits, Sanisphere monitors and adapts the waste treatment ecosystem according to the attendance and conditions of the location, in particular the humidity level with the reuse of rainwater.
- The technical rooms are adapted to the attendance so as not to require any draining. In case of any attendance beyond design, draining after 10 to 15 years may be considered.
Waterless toilets designed for users comfort
- Sanisphere toilet cabins are hygienic, modern, clean and adapted to the accessibility conditions for people with disabilities.
- Simple signage, based on pictograms, allows the immediate understanding of how it works.
- Without the addition of sawdust, these toilets were designed for a use similar to a water toilet.
Our buildings are often located on sites isolated from any network. We therefore make it available to users in each cabin:
Regardless of the type of toilet we use on a daily basis, two main nuisances affect them and make them unpleasant to use: the sight of dirt and foul odors. Sanisphere technology removed them with:
- The low-angled lighting in the cabin that keeps the downpipe and the conveyor belt in the shade by backlighting effect;
- The combined action of wind, sun and thermal inertia that creates a natural flow of air suction through the toilet seat, thus avoiding any smell in the cabin;
- The treatment ecosystem, which also acts on the smell, thanks to an adsorption of odorant molecules by the vermicompost.
