To stay within the proposed limits, humanity would need to reduce the rate at which it is harvesting N from the atmosphere by 75%. This would require minimizing losses and a significant increase in RRR.But also Phosphorous is getting critical, and there is no industrial production possible. It is estimated that the global available P from urine and feces could account for 22% of the global P demand (Mihelcic et al., 2011) http://www.sciencedirect.com/science/article/pii/S0045653511001925
Only to read the question on the slide , and to add … “and this at scale!”
This brings us now to the statement that RRR is actually not new, but we can hardly find it a scale, or in a viable form, especially in low-income countries. (Words can move from the slides to your notes). You could say that cost recovery is important and reuse offers so far largely unused options. We do not speak here about ‘profit’ but about any degree of cost recovery which would already be a huge progress.
This is the only slide with an animation. The current view disappears and shows how in an urban area the “loop” would look. Nothing more to say than what is written here, and then to press for the hidden slide which does not need any words either. (it is from our work with SANDEC/EAWAG in Kumasi, Ghana. It is still simplified as all households are in one box)
This is a summary slide which combines the key implications for addressing the presentation topic. Next comes briefly that WLE RRR is trying to walk the talk.
RRR as part of the CGIAR program on WLE
The one slide example of a business model on fecal sludge valorization we are implementing as PPP funded by BMGF in GhanaWe are also trying to walk the talk by implementing business models which allows us to learn valuable lessons.
Value from waste – converting a
problem into a resource

What if urban waste and used water could
have a second life in agriculture and the
reuse is actually safe and viable?
Where there's muck
• In many cultures, wastewater reuse and waste composting have a
long tradition, at least at household level.
• The technical knowledge is available.
• It is an apparent win-win situation for the sanitation, environmental
and agricultural sectors.
• Why is there no large compost plant or
wastewater reuse project in every southern city?
The concept is simple, at least for rural

It looks easy,
but in a city it looks more like…
Thus, for converting our larger urban waste
problems into a resource, we need strategic
partnerships and have to apply robust
economics and business modeling.
