Naturally intelligent technology that revolutionizes public toilets

The Sanisphere technology

For over 30 years, Sanisphere has developed a naturally intelligent technology that revolutionizes public toilets. Our approach is based on a simple and ingenious principle: the separation of solid and liquid waste, combined with a biological treatment ecosystem.
Discover how we have created toilets that never clog, are odor-free, and waterless.

Mastery of the treatment ecosystem

A living and regenerative ecosystem:

  • Our technology relies on a powerful ally: nature.
  • A treatment ecosystem composed of earthworms, bacteria, fungi, and insects significantly reduces the volume of organic matter and processes it over time.

Adapted monitoring and continuous optimization:
Sanisphere does not leave nature to work alone. During annual maintenance visits, our team monitors and adapts the ecosystem based on usage and site conditions.

FLEXIBLE URINE MANAGEMENT

Controlled urine management, adapted to each context

At SANISPHERE, urine management is conceived as a lever for environmental, technical, and economic control. Depending on the site context, uses, and client objectives, two complementary solutions can be implemented.

Connection to the wastewater network (EU)

When the site can be connected, urine can be directed to the existing sanitation network. This solution allows for simple and controlled integration into an urban or already equipped environment, while retaining the benefits of a waterless toilet in use.

  • Easier integration into existing infrastructures
  • Compliance with local regulatory requirements
  • Controlled operation for communities and site managers

Urine storage and recovery

For unconnected sites or when the objective is to go further in the environmental approach, SANISPHERE offers the installation of dedicated storage tanks. Urine is then collected, stored, and recovered, particularly in a circular economy logic.

  • Total autonomy, without network connection
  • Reduction of discharges and control of flows
  • Potential for agricultural or experimental recovery
  • Solution particularly suited for natural, event, or isolated sites

Odor prevention and hygienic management

The separation of solid and liquid waste prevents cross-contamination and facilitates their management. For stored urine, we offer specific cleaning of the urine tank and the elimination of struvite deposits (odor and risk prevention). This approach ensures hygienic and odor-free management, while recovering a valuable resource rather than losing it.

Natural Ventilation

To prevent odors in the cabin, SANISPHERE technology uses the combined action of wind, sun, and thermal inertia to create a natural airflow that draws air through the toilet seat, thus preventing any odor in the cabin.

The treatment ecosystem also acts on odors by absorbing odor molecules through vermicompost.

a
100% comfortable cabin

Sanisphere cabins offer an optimal comfort experience, designed for both users and operators.

Designed with quality materials, they guarantee a clean, welcoming, and hygienic environment. Sober, modern, and refined.

Simple signage based on pictograms allows for instant understanding of its operation.

100% Hygienic cabin

Each Sanisphere cabin is equipped with a hand sanitizer dispenser and toilet paper to ensure hygiene. Coat hooks, interior and exterior signage complete the equipment.

Frequently asked questions about our public dry toilets

How do Sanisphere toilets work without water or electricity?

Sanisphere technology is based on a patented principle of solid and liquid waste separation. A simple press of a pedal activates a conveyor belt that moves solids to a vermicomposting area. Liquids are directed to a separate drainage circuit. This ingenious system, combined with natural ventilation, ensures autonomous and ecological operation.

No, there are no odors. The design of our toilets creates a natural airflow that draws air from the cabin through the bowl, preventing any odors from rising. The immediate separation of urine and feces also prevents the formation of ammonia, the main source of bad odors. The olfactory comfort is often considered superior to that of traditional flush toilets.

Maintenance is considerably simplified. Cabin cleaning is easy (smooth surfaces, no corners) and can be done with plenty of water. Regarding the technical room, compost emptying is only necessary every 10 to 15 years on average, thanks to the work of microorganisms that reduce the volume of matter. Sanisphere offers maintenance contracts to ensure your peace of mind.

Absolutely. Each cabin is designed to offer optimal comfort, with the following characteristics:

  • Included equipment: They are clean, modern, and equipped with a hand sanitizer dispenser and paper.

  • User experience: Usage is similar to conventional toilets, making them very intuitive.

  • Visual cleanliness: The absence of sawdust and a specific design (including lighting) conceal the technical part, ensuring a pleasant experience.

Yes. The majority of models are adapted to accessibility standards:

  • Specific range: The SANITER range, in particular, is designed to be fully compliant with PRM standards.

  • Amenities: The cabins have grab bars and sufficient maneuvering space.

  • Adaptability: Options such as manual pedal activation (instead of foot) are available to facilitate use by everyone.

Sanisphere stands out for its experience and status:

  • Pioneer of eco-responsible public toilets since 1991.

  • Sawdust-free technology with unique and patented separation.

  • SCOP type company, committed to quality, durability, and innovation.

  • Offers a complete solution (from design to maintenance) with “Made in France” expertise and ISO 9001 certification.

The system allows for intelligent effluent recovery:

  • Solid waste: It is transformed into rich, stable compost directly on site.

  • Urine: Rich in nutrients, it can be stored for agricultural recovery (natural fertilizer) or managed by controlled infiltration.

  • The whole contributes to a circular economy.
