Perspectives are different frameworks from which to explore the knowledge around sustainable sanitation and water management. Perspectives are like filters: they compile and structure the information that relate to a given focus theme, region or context. This allows you to quickly navigate to the content of your particular interest while promoting the holistic understanding of sustainable sanitation and water management.
Commercial large-scale production of struvite from sludge digester supernatant in North America.
Website of the Global Phosphorus Research Initiative (GPRI), a collaboration between independent research institutes in Europe, Australia and North America. The main objective of the GPRI is to facilitate quality interdisciplinary research on global phosphorus security for future food production. In addition to research, the GPRI also facilitates networking, dialogue and awareness raising among policy makers, industry, scientists and the community on the implications of global phosphorus scarcity and possible solutions.

This case study reports the establishment of a sustainable, affordable and safe school sanitation system in a rural area in Armenia. A total number of 7 Double-Vault UDDTs serve ca. 350 students (females and males) and 26 staff members. Urine is stored for 6 months before application.

The document compiles the assessment of different UDDTs designs with respect to the construction materials used (e.g. country burned bricks, cement hollow blocks, ferro-cement, etc.) and their associated construction costs. Optimization and cost estimates are based upon the assessment of various designs of UDDTs applied in India and bills of quantity (BOQ).

Urine diversion vacuum flush toilets were installed in an urban building. Urine collected in the source-separation sitting/squatting toilets as well as the waterless urinals is drained by gravity. Faeces are withdrawn by vacuum suction. There is currently no reuse of urine and brownwater, but they flow to the sewer.

Urine diversion low-flush toilets where installed in public toilet blocks of the Olympic park. Urine was collected for reuse and brownwater was treated in a septic tank and moving bed reactor before being transformed into compost. The aim of the system was to interlink the sanitation material flows as a water and nutrient source with the green areas of the park as a water and nutrient sink. Reduced water and energy demand as well as the substitution of fertilizer by urine and faeces-derived manure were expected advantages.
