Improved and promising fecal sludge sanitizing methods: treatment of fecal sludge using resource recovery technologies

The global challenges that face sustainable sanitation services in developing countries are the lack of fecal sludge (FS) management; this is due to the rapid urbanization and population growth as it generates enormous quantities of fecal sludge. The extensive use of unimproved sanitation technologi...
