Thanks to a helping hand from Minister of the Environment Ida Auken, a new phosphate plant has been commissioned.

“This project is a fine example of how well a potential problem can be turned into a benefit thanks to collaboration. The future looks bright for innovation in Denmark.”

These were words of Minister of the Environment Ida Auken, when she cut a ribbon green leaves to officially open the new phosphate plant in Aarhus. The plant is quite simply designed to extract struvite from waste water slurry, which has a high phosphate content. And since phosphate is a scarce resource, which can be used as fertiliser for instance, there’s a lot to be gained from extracting it from waste water.

Created in partnership
The Aaby Purification Plant is the result of a partnership between Aarhus Water, Grundfos and Norconsult.
