Struvite precipitation as an attractive option for phosphorus recovery – short report from a P-Net event

On February 22, the possibilities of P recovery via struvite precipitation were discussed and classified at an event in Braunschweig. The event entitled “Struvite precipitation as an attractive variant of phosphorus recovery – an offer to exchange process engineering experience” was organized by the research association “P-Net – Regional Network for Resource Efficient Phosphorus Management”.

At the event, it became clear that the advantages of this phosphorus extraction must be made more visible; there are several providers of processes that are almost ready for the market. Struvite fertilizer is also a valuable product for agriculture. In addition, there is still a lot of work to be done by the players: The production volume, for example, has so far been rather small, and wastewater treatment plants would have to adapt their process technology and make investments.

The exchange in Braunschweig helped to discuss the developments and open questions and to drive the research work forward. If you are interested in details and an exchange on the topic, please contact pnet@isoe.de.
