Re: What next?
Well, I would say Waternet would take this initiaitive to install such machines which convert the urine into useful fertilizers with ofcourse some part of the funding from government. I understand that installing such machines would be very difficult and unviable in residential areas but consider having them in theatres, malls, big office buildings, public transport stations, etc.

Re: What next?
@Venks: Well, they will take fertiliser out of the urine they've collected in this campaign, but I don't think that's your point.

They are using this to campaign to get fertilisers recognised as fertiliser, whereas at the moment they are legally recognised as waste. That would be one tangible benefit. But I'd turn the point back on you and ask what you think they should be campaigning for? The introduction of waterless toilets in public places and, eventually, the whole city perhaps?

Re: What next?
The efforts of Waternet are absolutely laudable. But, I feel that Waternet just should not stop here. After making people realize that urine can be a source for generating fertilizers, it should take further steps to utilize the lessons learnt in by arranging such campaigns.

Rich, whats the point in just making people realize that urine can be reused if they are not going to do something with it once the campaign is over. People will just forget about such a campaign after few days as they get busy with their daily chores.

Re: What next?
Good questions, Venks. I don't think it is Waternet's intention to set up urinals in Amsterdam for the long-term with the specific intention of gaining pure urine to turn into fertiliser. The main aims of the Green Urine campaign are to tell people that fertilisers can be created from urine; to link this in with a scheme to beautify the city; and show how technology like this could be part of the green economy. The main aim has been to raise awareness rather than run a pilot scheme.

So what is the next step?

Well, the company is setting up the largest phosphates processing plant in the Netherlands, which is due to open by the end of 2014. My understanding is that it is only planning to take the phosphates from sewage and urine, not other minerals.

The company has also stressed how that factory has a collection point for pure urine. But what, you may be thinking, is the purpose of having a collection point if nobody actually has any pure urine to send to the factory? Well, my understanding is this pure urine will come from waterless toilets used at music festivals and other major live events. Although, if the whole city of Amsterdam did move to waterless toilets (and I'm not suggesting that it will!), that would clearly boost supply. I hope that helps a bit. Thanks for asking.

What next?
Thanks @Rich, for entertaining all of us here. We all had a good share of our laughs. We know that urine and other wastes that our body produces are a good source of fertilizers for plants. However, I fail to undertstand whats next in store for the Waternet? Are they planning to take it to a larger scale? Apart from phosphate, are they planning to extract other useful minerals from the urine?

Re: Men only?
This is interesting, Moomin. Is this still being done? I wonder how the quality of that paint was, too!

Re: Men only?
Yes, I was about to bring up those urinating contraptions made for women! With these developments and plans, I wonde why someone didn't think of this sooner. Just think of all that "waste" going to waste!

Re: Men only?
Mr. Heap, you have taken the UBM Future Cities Journalistic Prize, as serious as you intend to be I'vd not laughed so much from an article in a long time.  This is really an interesting concept and I wish it success.  This would be another renewable resource on hand. (pun intended)

Re: Men only?
@moomin-mashka: Interesting story, but I don't think Amsterdam officials are quite this liberal. They don't want people getting so rowdy that they end up here.
