On Sunday, 19 November the Fosfaatspagaat Symposium was held in the Metaal Kathedraal in Utrecht. The event was organised by the<\/p>\nSFYN<\/abbr><\/i>Slow Food Youth Network (SFYN) is an international youth movement dedicated to a good, clean and fair food system. As part of the international Slow Food Network, SFYN wants to promote good food that is produced as sustainably as possible and for which the farmer receives a fair price.<\/i><\/span>\n

Utrecht together with SF Utrecht and the Metaal Kathedraal. SFYN Utrecht\u2019s annual theme is \u2018Poep onder de loep\u2019 (\u2018Taking a look at poop\u2019), and they organised the symposium to delve more deeply into the subject.<\/p>\n<\/div>\n

During the symposium Renske Verhulst, of the Nutrient Platform<\/a>, gave a great presentation on a cross-sectoral network of 35 organisations dedicated to closing the nutrient loops and creating markets for recycled nutrients. KWR is a member of the Nutrient Platform.<\/p>\n

Phosphorus<\/h2>\n

Phosphorus is a vital element for all life on earth. It\u2019s like oxygen and water. And phosphorus has no substitute \u2013 so, no phosphorus, no us. The supplies of this element are however finite and unevenly distributed over the planet. This, at a time when in the Netherlands there\u2019s talk about excessive manure that results in much of our agricultural land being phosphorus-rich. At the same time, the excessive phosphorus contaminates surface waters, and this valuable raw material is often seen as waste.<\/p>\n

Recovering phosphorus from wastewater<\/h2>\n

After the break I spoke about the TKI Sustainable Airport Cities project<\/a>. The project involves the recovery in a pilot of phosphorus (struvite) from Schiphol\u2019s wastewater. The recovered phosphorus product is tested for quality and contamination. After establishing that it meets legal requirements for recovered phosphorus, it is used as an alternative to the artificial fertilisers used at the airport<\/a>. Today, phosphorus is being recovered at several wastewater treatment plants in the Netherlands and some abroad as well. This was the subject of the VPRO programme \u2018Tegenlicht\u2019<\/a> in March 2014.<\/p>\n
