Sewage sludge: pollutant and raw material source at the same time (German article)
Sewage sludge mono-incineration for recycling phosphorus – Thermal sewage sludge utilization as the basis for recycling the vital resource phosphorus
Sewage sludge is the waste of wastewater treatment in which pollutants are concentrated. In addition to pollutants, they also filter phosphorus from wastewater. An oversupply of phosphates leads to the eutrophication of streams, rivers and lakes and ultimately to the death of water bodies. 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)

Powder expertise for demanding tasks – Targeted plant modifications for fluid bed processes (German article)
The fluid bed is a technology that, with the right modifications, can be used for a variety of different processes. With the right expertise, individual process steps such as drying, granulation and agglomeration can be combined.
Drying processes generally describe processes for removing water or another liquid. However, exactly how the liquid is removed from a moist bulk material or a solution or suspension loaded with solids is an open question. Powder manufacturers have numerous methods at their disposal to remove the liquid from a product.
Fluid bed systems are flexible and allow processes such as agglomeration, coating, encapsulation, spray stiffening or spray drying to be carried out.
Targeted modification of existing plants often enables successful process design and optimization at lower investment costs.

Food, feed and pet nutrition: a convergence of industries
Food mega-trends such as added health benefits, natural raw materials and sustainable sourcing are becoming increasingly important for another large target group: animals. Even before the pandemic, the market for high-quality pet food was booming while the livestock feed market was going through a repositioning exercise. Ingredient suppliers are using their expertise to drive these industries forward.
Functional or active ingredients such as vitamins or probiotics, enzymes, yeasts, essential oils, proteins or microorganisms must be optimised and adapted for industrial processes, storage and feeding conditions. Their efficacy depends on their release profile (being pH-dependent, for example), which should be aligned with digestive processes. Granules and dry feed pellets offer convenient dosing options, especially those that are dust-free, temperature-stable and free-flowing. Plus, with fluidised and spouted bed equipment, liquids can be spray granulated or enclosed in microcapsules for convenient administration. Glatt Ingenieurtechnik, a leading global plant manufacturer and process expert, offers feed producers process development, technology and plant expertise from a single source.

PHOS4green – Implementation of a Plant for the Production of 60,000 t/a of Fertilizer from Sewage Sludge Ash at Haldensleben (German Article)
PHOS4green is a patented, unique phosphorus recycling technology that releases phosphate from sewage sludge ash and converts it into ready-to-use, standardized fertilizers. Glatt, a globally recognized market leader in fluid bed technology, has with Seraplant as a partner a highly efficient process developed, that recovers the essential and soughtafter nutrient phosphorus from sewage sludge ash and makes it usable for standardized phosphate fertilizers granules using a fluidized bed spray granulation process.
The extraction of the phosphate from the ashes is performed by a simple, flexible and stable process flow with well controllable reaction steps. Fluctuations in the composition of the sewage sludge ash are easily compensated by adjusting the recipe, which ensures a consistently high quality. The generated granules are dust-free, long-lasting and storage-stable, and have a compact, homogenous structure. They can be directly bagged, marketed and dosed as per a normal fertilizer. The solubility of these kind of granules is readily adjustable to the application. Furthermore, being dense, the abrasion-resistant surface reduces undesirable drift effects during application.

Pulsed Multiphase Flows—Numerical Investigation of Particle Dynamics in Pulsating Gas–Solid Flows at Elevated Temperatures
Although the benefits of pulsating multiphase flows and the concomitant opportunity to intensify heat and mass transfer processes for, e.g., drying, extraction or chemical reactions have been known for some time, the industrial implementation is still limited. This is particularly due to the lack of understanding of basic influencing factors, such as amplitude and frequency of the pulsating flow and the resulting particle dynamics. The pulsation generates oscillation of velocity, pressure, and temperature, intensifying the heat and mass transfer by a factor of up to five compared to stationary gas flow.

Glatt Powder Synthesis – Pioneering Process for Groundbreaking Particle Synthesis
Future materials such as high-energy and safe battery components, more economical membranes, orthopedic ceramics, functional additives or high-performance pigments must provide more than the current properties of existing material components. A common issue within each of these applications is the high levels of powder performance that are required. Therefore, completely new products or novel innovations require powder materials that must first be developed and then manufactured in the necessary quantities. With APPtec®, plant manufacturer Glatt has succeeded in overcoming these challenges and established a mature continuous process technology to produce future materials at both laboratory scale for research purposes and at industrial levels. Time-consuming and risky scale-up procedures are eliminated because of the size-independent conditions — fluid mechanic and thermodynamic — that exist from lab- to commercial-scale production.

Why contract manufacturing is both critical and crucial
For decades, large companies have outsourced production capabilities, thus driving globalisation – but also contributing to the decline of domestic industries. Digitalization, however, means it makes sense for more and more well-known global players to relocate production back to Europe. Contract manufacturing, for example, gives an idea of where this journey can take us.
- originally published in the magazine ‘Agro FOOD Industry Hi Tech’ – vol. 30(4) July/August 2019, pages 62–64 (TEKNOSCIENZE Srl, Milano)
The signals for contract manufacturing are green. The outsourcing of production and the division of labour are key factors for seizing market opportunities and growth in the post-industrial age. For Europe as a production location, the rising demand for wage capacities offers great potential. But the European success model also depends on the economy and political efforts to preserve the achievements of the European Union and develop them for the future. Against this background, it is to be hoped that Great Britain, the cradle of industrialisation and one of the most important European economies, will fi nally cancel Brexit.
New waste-free process produces fertilizer from phosphorus-containing ashes
With “PHOS4green”, Germany based fluid bed pioneer, Glatt, presents a new two-stage method that extracts phosphorus from sewage sludge ashes and converts it into ready-to-use fertilizer granulates.
More than 90 percent of the world’s phosphorus reserves are outside Europe. For this reason, Germany was the first country in the European Union to regulate the recovery of phosphorus by law. As the amended Fertilizer Ordinance (DÜMV) restricts the direct soil-bound recycling of phosphorus-containing sewage sludge, many large disposal companies will be forced to establish alternative recycling methods within the next 12–15 years. Current phosphorus recovery processes have the disadvantage of producing large quantities of waste and being restricted to a certain raw material matrix. DüMV also places high demands on recycling fertilizers, which in many cases are not yet met.

Shaken or Stirred – Agglomeration with fluidized bed technology
Whether it’s infant formula, soups or shakes, instant foods are inseparably linked to many areas of life. If powdery substances are to be dissolved or dispersed in hot or cold liquids, then agglomeration is a vital quality improvement process, with fluidized bed technology providing the widest range of optimization possibilities.
High dust content, inadequate bulk density, lack of abrasion resistance or an undesirable color are just some of the challenges manufacturers face when working with dry materials. Coffee, cocoa or instant mashed potatoes, for example, are not only expected to be storage-stable, free-flowing and easy to dose, they should also disperse, dissolve or swell in a lump- and residue-free way. For the optimization of instant properties, fluid bed technology is a proven, highly adaptable and established technology. The experimental development of critical parameters is essential and should be tested in laboratory and pilot-scale plants to get flawless instant quality products ready for market. It should be noted, however, that production parameters cannot be calculated by simply scaling-up experimental data. Master batches provide evidence that the lab-scale can be transferred to a batch-based or continuous production-size process.

Encapsulating volatile substances – Product optimization with artificial neural networks (German article)
Food and feed products have to be developed with a focus on high yields of active ingredients and low formulation costs at the same time. As a typical industrial application, the encapsulation of volatile substances, e.g. flavors or PUFAs (polyunsaturated fatty acids), into dense and free-flowing granules is explained in this paper. This process improves storage stability, protects the products from oxygen and can be carried out with a continuously operating spouted bed apparatus. (aticle in German language)
