The objective of any sanitation system is to protect and promote
human health by breaking the cycle of disease. Most of the existing
sanitary systems prevent exposure of humans to harmful
pathogens found in the excrement. These systems carry the waste,
remove pathogens and pollutants, and finally release the contents
back into the nature, often in large volumes of diluted wastes,
which leads to eutrophication. By shifting away from today’s
paradigm which focuses on what must be removed from
wastewater, to a new paradigm focusing on what can be recovered
sanitation systems may begin to be described as Resource
Recovery Systems
