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.

The Gentle Processing of Highly Volatile Oils by Fluid Bed and Spouted Bed Technology
Sensitive raw materials, especially those that are volatile or of natural origin, require particularly gentle process conditions. Spray granulation, spray coating and (micro)encapsulation procedures have proven to be methods of choice, as they enable high yields, low temperatures and bespoke properties.
When it comes to cosmetics, product development often focuses on proven, multifunctional ingredients. This is in addition to the ongoing demand for natural ingredients, as consumers increasingly look for effective cosmetic products that neither harm their health nor the environment. Glatt Ingenieurtechnik, the German expert in particle design, process development and plant engineering, offers unique particle processing solutions based on fluidised bed and spouted bed technologies for essential oils, collagens, active substances, stabilizers, enzymes, fragrances, aromas, vitamins and controlled release products, all of which can be optimally produced, protected and refined.

Process Technologies to Optimize Detergent Manufacturing
How can cleaning agents components be produced in a more environmentally friendly and effective way? With fluid bed and spouted bed technologies, plant manufacturer and process expert, Glatt Ingenieurtechnik, offers modern, established solutions.
As a manufacturer of consumer goods, the detergent industry must respond to megatrends like no other. One of these drivers is sustainability; eco-friendly biosurfactants have been available since 2009 and, now, alternative complexing agents such as α-ADA or MGDA-Na3 can be produced from renewable raw materials and used to replace phosphates. According to the German Zukunftsinstitut (Future Institute), the neo-ecology megatrend is causing a reorientation of the values of global society, culture and politics and will have a defining impact on the 2020s. Consumers and business partners alike are asking about transparent value creation and whether social aspects are being considered. As an example, seamless traceability has long been standard practice.
Yet, the ongoing microplastics debate calls for a rethink when it comes to encapsulated fragrances or when the fibres of functional clothing have to be fished out of wastewater. Solutions for all these requirements can only be realised if the chemical industry and original equipment manufacturers work closely together. Innovative raw materials is one side of the coin; technological advances in laundry washing is the other! …

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.
» 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.
In cooperation with an industrial partner and the Material Research and Testing Institute of the Bauhaus University Weimar (MPFA), the market leader for fluidized bed technology, Glatt Ingenieurtechnik, has developed a highly efficient process: PHOS4green extracts phosphate from sewage sludge ashes, which is then converted into residue-free, ready-to-use standard fertilizers using fluidized bed spray granulation. The project was funded by the Deutsche Bundesstiftung Umwelt (DBU). The process is an ideal way to close the gap in the phosphorus cycle by combining recycling with manufacturing and producing an end product that can be sold directly.

Formulation For Success – Fluid Bed Systemes as Key for the Production of Speciality Fertilizers
From improving durability and flowability through dust reduction to a pronounced depot effect or a targeted nutrient supply via better active ingredient distribution, fluidised bed technology can deliver many benefits. The shape and size of the fertilizer granules can be determined within a defined range. The quantity of fertilizer components delivered to the soil can be adapted optimally, and significantly higher product qualities can be achieved. Solubility and protection against external influences can also be markedly improved.
