[1] The diagram has a particular focus on treatment of the waste, and its final disposal or use.
The benefits to society of managing human excreta are considerable, for public health as well as for the environment.

An alternative term is "use of human excreta" rather than " reuse " as strictly speaking it is the first use of human excreta, not the second time that it is used.
A urine-diverting dry toilet (UDDT) is a type of dry toilet with urine diversion that can be used to provide safe, affordable sanitation in a variety of contexts worldwide. . The separate collection of feces and urine without any flush water has many advantages, such as odor-free operation and pathogen reduction by dry
