The Banza Toilet is a sanitation solution in response to the lack of adequate facilities for families in informal settlements worldwide. Compact and foldable, the Banza Toilet can be utilized when space is limited. The product uses biodegradable bags for human waste containment and disposal, providing a hygienic means of handling human waste for toilet users and service providers.Interview with designer
Alternatives include an in-home flushing toilet (must have access to running water), an in-home toilet without access to a sewage system, PeePoo bags, public latrines, and open defecation.

Service organizations typically will purchase the toilet and provide them on a community-wide basis to families together with the necessary services of collecting and processing of waste. They also have potential to be distributed among NGOs and related agencies that conduct disaster relief operations or operate refugee encampments. Banza has identified interest among rural residents and individuals that are home-bound and have difficulty accessing public sanitation facilities.Interview with designer

Emptied when biodegradable bags are full
The toilets separate solid and liquid waste to optimize collection and processing. The seats are designed to seal the toilet when closed to minimize odors. The toilets are ergonomically designed to be compact for homes with limited space and they use biodegradable bags for human waste containment and disposal. These bags contain no plastic, and while durable, they dissolve in water or when composted.Interview with designer Experts indicate that further details are needed regarding disposal guidance/process for the provided bags (i.e. Who collects the bags? Where is the waste brought?).
