Main Objectives of Sustainable Sanitation •To Reduce Health Risks related to Sanitation,Contaminated Water and Waste •To Prevent Pollution of Surface and Ground Water •To Prevent Degradation of Soil Fertility •To Optimise Closing the Loop of Human Excreted Nutrients, Organic Material and The Water Cycle Considering Energy & CO2 Balances •Economically and Ecologically Sustainable and Culturally Acceptable Systems
- 4. Bolivia plane crash victim drank urine to stay alive Sole survivor tells of three-day ordeal eating insects while awaiting rescue Minor Vidal, the Bolivian plane crash survivor is led out of the jungle by army officers. Photograph: Reuters Agencies in La Paz Sunday 11 September 2011 17.50 The sole survivor of a plane crash in Bolivia stayed alive for nearly three days by eating insects, drinking his own urine and painting an arrow on the ground with his blood to show rescuers his location. "He said he'd been trapped in the plane for more than 15 hours and that when he finally escaped he began to walk and survived by drinking his own urine and water from a lagoon."
- 8. Another solution to areas in developing countries with a dry climate is to install dry toilets which separate the urine from the faeces. In this way the urine can be directly used as fertilizer and the faeces can be stored in a non-humid alkaline environment for a lengthy storage period before being used as fertilizer (or for biogas production which we saw an example of at the SOS – Aldea infantil). In that way the pathogens can be destroyed. For less attendance one can build two toilets to alter between where the excrement in the toilet not used can be left long time enough to be safe to use as fertilizer.

- 11. Flow or Stream of Material •Human urine contributes to about 80 % of the load of N and 50 % of the P load of conventional domestic wastewater •Human Urine treated conventional requires large amounts of energy producing large amounts of sludge
- 12. Flow or Stream of Materials •We Excrete most of the Nutrients we Consume •Human Urine contributes with only 1 % of the Volume of Household Wastewater but contains 80 % of N, 55 % of P and 60 % of K and less than 0.6 % of Cadmium and 0.06 % of Lead
- 13. Phosphorus •One Person Excrete 1 KG P/year. •0.7 KG in Urine and 0.3 KG in Faeces. •Human Phosphorus Returned to Soil Would Cover 80 % of P Demand •In Agriculture Short of Phosphorus Human Excreta could be a Golden Opportunity. •In 100 years Phosphorus Could Be Gone.
