The fact that phosphorus is filtered out during wastewater treatment because of its serious consequences for the aquatic ecosystem in turn makes sewage sludge an important source of raw materials. It is this ambivalence of pollutant and raw material source that has led to thinking about alternative disposal methods. One such is sewage sludge mono-incineration. (Article in German language)

Save the Date: March 1st – 12:00am! Dr. Jens Bergmann, Sales Manager – Process Technology Food, Feed & Fine Chemicals at Glatt Ingenieurtechnik GmbH, will inform about Glatt as partner for particle design and plant manufacturing for functional granules from your product idea to industrial production. Fluid bed technology is the key to environmentally friendly production of effectively acting, abrasion-resistant, easy-to-dose, storage-stable fertilizers.
Glatt Ingenieurtechnik is exhibiting for the first time at IFAT, the world’s leading trade fair for environmental technologies in Munich. The company will showcase its patented PHOS4green technology to recover phosphorus from sewage sludge ash and convert it directly into ready-to-use phosphate or compound fertilizers. On booth A4.509, visitors will be able to learn more about this innovative approach that’s already being successfully used at an industrial scale.
Meet the Glatt experts at Chemspec Europe on 31.05. – 01.06.2022 for Particle Design & Engineering from Nano to Macro:
Processing of liquids and powders at 40 – 1300 °C: drying, granulation, coating, calcination in ONE process step. Batch and continuous mode. Hotmelt Processing. Solvent Recovery.
High-performance powders, granules and pellets. Homogeneous. Dustfree. Unique. Adjustable properties. Functionalization.
Part 1 of this article will highlight a scientific study on the long-term bioavailability of the nutrients in different phosphorus fertilizers. Part 2 will provide a report on the first German production plant and present a research project in the Frankfurt Rhine-Main area. Jan Kirchhof, Glatt Ingenieurtechnik GmbH, Germany, reports on a laboratory experiment with phosphorus fertilizers and two current projects.
The first fertilizers produced using the PHOS4green process have been available on the German market since June. The technology, which breaks down the phosphorus contained in sewage sludge ash and makes it reavailable in marketable end products, was developed by plant engineering and process expert Glatt Ingenieurtechnik in cooperation with fertilizer specialist Seraplant.
Under the topic “Phosphorus Recyclates – Not for the garbage can!?” this year’s forum event took place in Frankfurt am Main on September 9, 2021. The experts of Glatt PHOS4green thank you for the interest in the presentation of Jan Kirchhof, Glatt Ingenieurtechnik and Henning Schmidt, Seraplant on phosphorus recovery from sewage sludge ash and its conversion into ready-to-use standard fertilizers.
At the 2nd Conference of abonocare® – sustainable nutrient recycling from organic residues Dr. Michael Jacob will give a lecture on ‘Fertilizer production from N- and P-rich recyclates using fluid bed spray granulation’. He will show product examples and present an industrial-scale reference plant at Seraplant in Haldensleben, Germany.
Production starts at first German PHOS4green plant for recycled fertilizers. Residue-free production of ready-to-use fertilizer from phosphate-containing sewage sludge ash is now possible, thanks to plant manufacturer and process expert Glatt Ingenieurtechnik, and fertilizer specialist Seraplant. The official commissioning on May 31, 2021, was attended by Prof Dr Armin Willingmann, Saxony-Anhalt’s Minister for Economics, Science and Digitalization.

Sewage sludge treatment and recycling is also an important topic for Swedish municipalities.
Under the organization of Envisys AB, a technical meeting on sewage sludge will be held in Helsingborg, Sweden. Jan Kirchhof, Senior Sales Manager Process & Plant Engineering, Glatt Ingenieurtechnik GmbH, will inform about a PHOS4green plant for the production of fertilizer from sewage sludge ash.
