The primary mechanism of biological waste recycling in the natural environment is performed by other organisms such as animals, insects, soil microorganisms, plants, and fungi, which consume all available nutrients in the waste, leaving behind fully decomposed solids that become part of topsoil, and pure drinking water that has been stripped of everything that can possibly be consumed and ...
A shit flow diagram (also called excreta flow diagram or SFD) is a high level technical drawing used to display how excreta moves through a location, and functions as a tool to identify where improvements are needed. [1] The diagram has a particular focus on treatment of the waste, and its final disposal or use.
A case study of a decentralized wastewater system at on-site level with treated effluent reuse was performed at the Botswana Technology Centre in Gaborone, Botswana. [22] It is an example of a decentralized wastewater system, which serves one institutional building, located in an area served by municipal sewerage.
While an effluent sewer can use gravity to move waste, the ability to move waste with a pressure system can be a big advantage in places where a gravity system is impractical. Compared to conventional sewer systems, effluent sewer systems can be installed at a shallow depth and do not require a minimum wastewater flow or slope to function. [1]
While EDS are designed chiefly to sterilise liquid waste, they can in some instances sterilise solid material carried by the liquid effluent. However the EDS may require grinders [4] to break down the solid materials before they enter site of sterilisation in the EDS, and macerating paddles [5] to stir effluent held in tanks, reducing congelation.

Waste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. [1] This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms.
