High-performance fertilizer from sewage sludge ash (German Article)
The new PHOS4green process makes it possible to produce ready-to-use, phosphorus-containing fertilizer granules in a two-stage, residue-free process. The spray-granulated, plant-available fertilizers can be directly filled, distributed and applied in the field. The pollutant content of the new fertilizers is significantly below the limits of the DüMV. (Article in German language)
