PHOS4green on an Industrial Scale at SERAPLANT, Haldensleben, Germany

First large-scale production for 60,000 tons of phosphate-containing straight and compound fertilizers being recyclates from sewadge sludge ashes.

In spring 2021, development partner SERAPLANT, a fertilizer manufacturer based in Saxony-Anhalt, Germany, started operating a Glatt PHOS4green production plant. The produced phosphorus-containing fertilizers are recyclates from a phophorus recovery technology from sewadge sludge ashes. The new plant is designed for an annual production of 60,000 tons of phosphate-containing straight and compound fertilizers. At the heart of the process is the AGT 750 spray granulation unit. PHOS4green is the first recycling process for phosphorus recycling to be implemented on an industrial scale anywhere in Germany. The target groups are agricultural businesses in conventional and organic farming, agricultural and horticultural wholesalers and the fertilizer industry. Glatt was commissioned with the planning and implementation of the complete plant technology, from raw material delivery – via suspension preparation and subsequent fluid bed granulation – to finished fertilizer. According to a press release dated 08.11.2019, SERAPLANT invested 20 million euros in the construction with support from the state of Saxony-Anhalt. Additional funding of almost five million euros came from the funding program of the joint task “Improvement of the regional economic structure” (GRW). The GRW is part of the overall German support system for structurally weak regions under the auspices of the Federal Ministry of Economics. The innovative production facility will create more than 20 new jobs, which will be filled in the coming months.
