Mosan

Mosan is a circular sanitation system, including the Mosan Dry Toilet for in-home use. All Mosan products have been designed in co-creation with affected people and stakeholders. 

The circular sanitation service consists of 5 key steps:

Containment:  The Mosan Toilet has two removable containers, one for urine and one for feces. Each has a 9L capacity. With 5 family members the toilet can be used for 2-3 days. For larger families extra containers can be provided. Ease of use, durability, low maintenance and an aspirational design are important aspects. Key functions are:

• Ergonomic and elegant design
• Clean separation of urine and feces into removable containers
• Durable HDPE plastics, expected lifetime more than 5 years
• Feces are covered with dry materials (e.g. ash or sawdust) to prevent smell and flies

Emptying: Twice a week families bring their toilet containers to service stations (or service trucks), where Mosan staff empties the materials into bigger barrels and disinfects the toilet containers.

Transport: Mosan staff takes care of the transport from collection stations to the transformation center.

Treatment/Transformation: Urine and feces are separately processed and transformed into valuable products that can be reintroduced to the local and international market.

Reuse: transformed excreta can be used as a soil amendment, fertilizer, soil detoxification, or as fuel.

The expected lifespan of the toilet is minimum 5 years.^{Interview with representative in 2019}

For the 1-year pilot project in Guatemala, five families (serving 20 people) were provided with a Mosan toilet. Mosan and partners reported the following results: 73,000 L of water were saved, 6,800 L of urine and 3,800 kg of feces were prevented from contaminating the environment, 350 kg of biochar was produced, and 2.2 tons of carbon dioxide emissions were avoided, Additional information can be found here.

All of the service staff need to wear safety equipment and follow a strict risk sanitation safety plan. Regular capacity building and hygiene training is conducted.
