Ash2Phos plant in Schkopau

In 2021, Phoshorgewinnung Schkopau GmbH was formed by GELSENWASSER AG and EasyMining Services Sweden AB to build the first Ash2Phos-plant in the world.

The plant will be built at the Schkopau Chemical Park in the Saxony-Anhalt region in eastern Germany, and have a capacity of 30 000 ton ash from incinerated sewage sludge per year. It will receive ash from the Gelsenwasser incineration plant in Bitterfeld-Wolfen but will also be able to treat ashes from other incineration plants.

The first plant in Schkopau will serve as a full industrial scale demonstration plant, treating ashes from various suppliers joining our innovation partnership from all over Germany. After successful demonstration and once the roll-out in other regions has started, the Schkopau plant will focus on regional ash inputs.

The investment decision was taken in May 2024 and the basic engineering for the plant is finalised.
