Before, I was ashamed. Now women come to me to learn.
The Crisis
3.6 billion people—half of humanity—live without safely managed sanitation. For women in informal settlements, this is not merely inconvenient; it is dangerous. When there is no toilet, women must walk to the bush at night—where they are vulnerable to harassment, assault, and rape. The absence of sanitation infrastructure is a form of gendered violence.
Circular Sanitation
The Mobile Dry Diversion Toilet (MDDT) is a composting toilet system that separates urine and feces, requires no water or sewage connection, and produces fertilizer as a byproduct. It is affordable to produce, locally maintainable, and designed to be owned and operated by women.
Key Features
Waterless
No connection to water supply or sewage required
Circular
Human waste becomes agricultural compost
Women-led
Designed with women, for women, operated by women
Scalable
Replicable across contexts without centralized infrastructure
Dignified
Private, safe, lockable, clean
Impact to Date
Since 2021, sanloop has deployed MDDT units across Lagos, Nigeria and Nairobi, Kenya. In 2026, we expand to Emene (Nigeria) and Nyali (Kenya). Our Women for MDDT network demonstrates that sanitation infrastructure can be scaled through community-led replication.
sanloop develops and deploys circular sanitation systems for communities without access to conventional infrastructure. Our technology, the Mobile Dry Diversion Toilet (MDDT), separates and composts human waste on-site—requiring no water, no sewage connection, and producing fertilizer as output. We work with women, for women—because when sanitation fails, women pay the highest price.
Circular by Design
Waste is resource. Our systems close the loop, returning nutrients to the soil.
Women-Centered
We design with women, because they bear the greatest burden when sanitation fails.
Systems Thinking
Infrastructure is not a product but a system—technical, social, economic, environmental.
