[PDF][PDF] Technological options for safe resource recovery from fecal sludge
Each day, humans excrete in the order of 30 grams (g) of carbon, 90 g of organic matter, 10-
12 g of nitrogen (N), 2 g of phosphorus (P) and 3 g of potassium (K). Most of the organic
matter is contained in the feces, while most of the N (90%) and P (70-80%) is contained in
urine. Potassium is equally distributed between urine and feces (Sobsey 2006). In
developing countries, most of the population relies on on-site sanitation technologies.
Currently, the management of fecal sludge (FS), the (semi-) liquid waste collected from …
