What I want to tell you is that in 2050 we don’t even have waste anymore. There will be no waste in 2050. Everything will be seen as a treasure, because we will have created what some smart people call a circular economy.
Water is a difficult commodity. It is free, and yet costly. It is simultaneously a private good, and a public good. It helps cities flourish financially, but now it is their financial burden. Almost nobody pays for the water per se. The cost of water is the cost of making it available at the right time, in the right place, and with the right quality.
