The Mosan toilet is a container-based sanitation (CBS) system that provides for urine-faeces separation.
Frontend: Mosan’s CBS presents a durable plastic container with a toilet seat, a lid and two containers within the larger container for urine and faeces collection. The urine container has a valve for smell prevention, while the faecal container is used with dry materials such as ash or sawdust to enhance drying and curb smell.
Emptying and transport: The Mosan team provides users with regular collection services where the staff exchange full containers with clean empty ones. Mobile communication, NFC code tracking and sms notification are employed to ensure effective and safe service. After the collection, the Mosan team transports the waste to a transformation centre.
Treatment & reuse/disposal: Urine and faeces are processed separately and transformed into useful by-products. The former is transformed into struvite while the latter is processed in a pyrolysis reactor to produce biochar, which can be used as a soil amendment as well as carbon sequester for reducing greenhouse gases.
Structure: The containers are made of durable plastic material in an ergonomic and elegant design. These can be fitted into any desired superstructure.
Ideal context: The Mosan solution is a CBS system which can be fitted into any desired space including superstructures, for use. Given the size, portability and resource-focussed aspect of the Mosan system, it is suitable in diverse non-sewered contexts including slum and rural areas.
