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.

Tailored monitoring and continuous optimization:

  • Sanisphere doesn’t leave nature to fend for itself. During annual maintenance visits, our team monitors and adjusts the ecosystem based on visitor traffic 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.

a
100% Hygienic cabin

Our cabins are designed to ensure impeccable hygiene under all circumstances. Thanks to their waterless design and separate flow paths, they minimize contact, splashing, and the spread of bacteria. The result: a clean, healthy, and comfortable space for every user, even during peak hours.

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 separating solid and liquid waste. A simple press on a pedal activates a conveyor belt that evacuates solids to a vermicomposting area. Liquids are directed to a separate drainage system. This ingenious system, combined with natural ventilation, ensures autonomous and ecological operation.

No, there’s no smell. The design of our toilets creates a natural airflow that draws air from the stall through the bowl, preventing odors from rising. The immediate separation of urine and feces also prevents the formation of ammonia, the main source of unpleasant odors.

Finally, a natural “blotting paper” effect takes hold within the system: a microbial film develops and traps odorous gases, helping to keep the cabin clean and odor-free.

No. SANISPHERE toilets are designed to make maintenance as easy as possible for municipalities and cleaning crews.

The cabin is easy to clean thanks to its smooth, seamless surfaces, which allow for quick cleaning, even with plenty of water. The absence of water and a sewage system also prevents the common problems associated with traditional restrooms: leaks, overflows, or water marks on the floor.

The material is processed using a biological treatment system. This natural ecosystem, composed of microorganisms and worms, gradually breaks down the material and significantly reduces its volume. As a result, the compost bin needs to be emptied only once every 10 to 15 years, on average.

For even greater peace of mind, SANISPHERE also offers maintenance contracts that enable local governments to ensure the longevity and proper operation of their facilities.

Absolutely. Each cabin is designed to provide optimal comfort, with the following features:

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

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

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

Yes. Most models comply with 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 operation (instead of foot operation) 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, sustainability, and innovation.

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

  • Solid waste
    It is processed directly in the toilet through a biological treatment process (earthworms and microorganisms) that breaks down the material and reduces its volume by 7 to 10 times. This natural system is self-sustaining, highly resilient, and functions even in challenging environments such as high altitudes. If the system is emptied before the material has fully decomposed, the compost can be sent to an approved composting facility.
  • Urine

    Three solutions can be offered to the customer depending on the site’s configuration: (1) connection to the public sewer system, (2) the installation of a drainage system following primary treatment in a pretreatment tank, or (3) the storage of urine in certified tanks for reuse as fertilizer through approved channels.
