After compost, PVC and non-ferrous metals from bottom ash, struvite will be the fourth secondary resource to be addressed within the International Green Deal North Sea Resources Roundabout (NSRR). Struvite is a specific mineral form of magnesium ammonium phosphate recovered from waste water. A working group of French and Dutch public and private sector experts has its first meeting in the Dutch embassy in Paris on October 7. The case, initiated by Suez, Veolia, Reststoffenunie and Waternet, will focused on the perceived barriers relating to the use of struvite in crystal form. It will specifically explore ways to facilitate the export of struvite recovered from municipal wastewater plants as a raw material for the purpose of producing fertiliser. The initiators hope that this case will be a first step towards creating a European market for struvite.
