Increasing need for nutrient recovery.
The increasing population of earth puts higher and higher demands on food production. The ability to supply phosphorus and nitrogen to our agriculture will determine whether we are to eradicate hunger – or not.
Meanwhile, the costs of mining for phosphorus are increasing and it is a finite resource where we know that peak production is imminent. We are also aware of the large amounts of energy needed to produce the vital nitrogen fertilization.
Ecology and Circular Economy are interrelated. With this in mind, ensuring that the cities of the future have a well-functioning nutrient cycle where nutrients from households are recycled seems especially important.
Again has a revolutionary solution to this problem.
