There are valuable resources trapped in city waste, including nutrients for soils, water for irrigation, and energy for household use. By creating business models for recovering and reusing these resources, we can help pave the way for reduced pollution and more sustainable food and energy systems.
Over the last ten years, researchers from IWMI have identified a number of options for safe resource recovery from Fecal Sludge. The options provide the stages and technical solutions available for safe recycling of Fecal Sludge and its by-products, mainly in agriculture.
These options provide an overview of some low-cost wastewater treatment technologies for pathogen removal, which can be adapted for use in urban and peri-urban areas in low-income countries where the wastewater is of domestic origin
The best available data on municipal wastewater production, collection, treatment, discharge and direct use for irrigation purposes is continuously collected and added to AQUASTAT, the FAO global water information system.
