Mosan - The Circular Sanitation Solution - An inclusive market-based sanitation service for low-income, densely populated settlements

More than 4.2 billion people lack access to safe sanitation (WHO). The consequences are disease spreading, high mortality rates, violence on women, and environmental contamination. Plus, the sanitation and water system is highly inefficient with 80% of the wastewater generated globally flowing back into the ecosystem without being treated or reused (The United Nations World Water Development Report, 2017). Mosan is providing dignifying, healthy and safe sanitation, while protecting and benefiting the environment by avoiding pollution and closing nutrient cycles. The Mosan solution is a decentralized, off-grid, in-home, and waterless service for people in densely populated settlements. The service ensures safe containment, transport and transformation of human excreta. Mosan employs circular economy principles, transforming excreta into valuable resources and reintroducing it into the economy thus shaping a paradigm shift and a creative movement that leads to long-term change. Mosan applies human-and planet-centered-design approaches, working closely with communities, building local capacities and ensuring high adoption rates
