Container-based sanitation

Container-based sanitation (CBS) (or cartridge-based sanitation) refers to a sanitation system where human excreta is collected in sealable, removable containers (also called cartridges) that are transported to treatment facilities. Container-based sanitation is provided as a service involving provision of toilets, typically dry portable toilets, and collection of excreta. The system incorporates measures to isolate excreta from human contact throughout the sanitation chain (i.e., during containment, emptying, transportation, treatment and disposal or reuse of excreta).

Its main application is for situations where alternative options that rely either on a sewerage system or on a hole in the ground (pit latrine) are not feasible. CBS is sometimes done in informal settlements in cities of developing countries.

The "cassette toilets" used in motorhomes have a similar concept, but are usually a type of small chemical toilet.

The world's population is urbanising at a pace that outstrips existing infrastructure and municipal capabilities, making society's ability to meet Sustainable Development Goals (SDGs) increasingly challenging. There is a need for an alternative sanitation option where on-site sanitation and sewerage are not feasible. Container-Based Sanitation (CBS) refers to a system where excreta is collected in sealable, removable cartridges that are transported to treatment facilities. Container-based sanitation isprovided as a service involving provision of certain types of portable toilets, and collection of excreta.

Examples of organizations that provide this service are Loowatt in Madagascar, Clean Team in Ghana, X-Runner in Peru, and SOIL in Haiti.
