The Global Sanitation Challenge

  • 2.3 billion people lack access to basic sanitation services (WHO & UNICEF, 2023).

  • Poor sanitation leads to preventable diseases, including diarrhea, cholera, and infections.

  • Water scarcity and electricity shortages limit access to hygienic toilet solutions.

Traditional sanitation solutions often require electricity or complex infrastructure, making them impractical for rural and underserved communities.

A cost-effective, low-maintenance, and sustainable alternative is urgently needed.

Impact on Public Health and Sustainability

Kirei contributes to global health and sustainability efforts by:

  • Reducing the spread of disease through better personal hygiene.

  • Lowering the dependency on non-biodegradable toilet paper, reducing waste.

  • Conserving water, as it requires significantly less water than traditional cleaning methods.


Promoting dignity and hygiene, especially for women, children, and the elderly.
