Thank you. I am a big fan of Arjen's work. I agree with Mr Ian Pearson to release pressures en strategic resources and I really enjoyed Guy's comparison with the air mask in planes.  Please allow me to add 1 point correlating all of you: some wastewater are easier to recycle than others, treated wastewater can even have a negative cost if coming from wastewater that generated energy, fertilisers or other profitable by-products. It is therefore important that some micro-pollutants and other noxious products are simply forbiden to be used because of heavy related costs to treat them (when possible). But forbidden them is almost an utopia so  at http://www.pranasustainablewater.ch/en/index.php  we work on the monetisation of wastewater resources when supplied with certain qualities and in the frame of wastewater infrastructures financed through the commoditisation of treated wastewater (there is still more than 80% of wastewater untreated at global level). The drastic changes in industrial processes must therefore involve also the content of products ending in wastewater. Isn't for example a non sense to pay fully biodegradable detergents more expensive than the one requiring more energy and money to be recycled (when possible if not costs on health and on the ecosystems must be added)? If the presently 85% of untreated wastewater are recycled while generating for example energy reducing the water//energy nexus, the water footprints might be the same as today (even if I push for more crops/productions per drops), the global water picture can change not because of wastewater generating revenues but because wastewater reuse would add value when adequate content. W2AREX (WasteWater Reuse Exchange) monetisation of wastewater is to influence the valorisation of its content at each wastewater reuse,  push the release of pressure on strategic resources and increase access to sanitation (thanks to the commoditisation of treated wastewater more wastewater valorisation infrastructures should take place) valerie@pranasustainablewater.ch

Nicely stated Valerie. Allow me to fill in the blanks. When doing natural bioremediation there are zero leftover wastes. All compounds have different parameters. 40 years doing this and we are still at Zero. Any and all perceived toxins are naturally chelated into their elemental nutritional state.  One thing is clear. (thank you for bringing it to our attention) So few are even attempting to clean and or recycle their waste water. At this point in time I most certainly do support all efforts in this direction.  No worries. Nature always wins in the end.
