Phosphorus Recovery on an Industrial Scale

Closing the Loop: Phosphate fertilizer from sewage sludge ash. Glatt’s PHOS4green technology provides an economically and ecologically viable solution suitable for closing the phosphorus cycle.
Ash-based recycling processes are among the most promising and economically attractive options when it comes to implementing the legally stipulated phosphorus recovery. 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.

Company information

Glatt Ingenieurtechnik GmbH
Glatt Ingenieurtechnik GmbH
Glatt is specialized in intelligent particle design for the generation and functionalization of powders and granulates with defined, adjustable properties. The focus is on particles and powders for pigments, catalytic, ceramic or battery materials as well as for granules and pellets as additives for e.g. industrial salts, detergents and cleaning agents, fertilizers, pesticides, food, feed, dietary supplements and pharmaceuticals. Encapsulation of flavors, enzymes, vitamins, microorganisms, probiotics or fatty acids (PUFA) is just as possible as encapsulation of essential oils and other active, sensitive substances to be protected. With Glatt APPtec®, a unique technology for spray calcination, it is possible to generate, coat and then calcine particles in a pulsing hot gas stream in a single process step. As a pioneer in fluid bed and spouted bed technologies, Glatt masters these important processes for the formulation and optimization of particle properties through defined spray agglomeration, spray granulation, spray coating or (micro)encapsulation as well as through combinations of these processes. Also in the high temperature range. Glatt supports the product idea from the early phase of product formulation through process development to scale-up to production scale. Under the leadership of the Glatt Process & Plant Engineering teams, customized production plants for nutrition, fine chemicals, pharmaceuticals, and biotech applications are successfully planned and commissioned. Worldwide. Whether based on powder synthesis, fluid bed or spouted bed technology, Glatt also offers certified contract manufacturing for customers without their own production capacities.

Spray (micro) encapsulation of sensitive substances in matrix form An overview of essential oil and vitamin case studies
Spray (micro) encapsulation of sensitive substances in matrix form
An overview of essential oil and vitamin case studies Phytochemicals are increasingly found in many food, chemical and agricultural items. Product and process optimization is becoming ever-more important in all of these industries, with a focus on quality, manufacturing efficiency, stability and formulation costs. Essential oils are volatile substances with a relatively high vapor pressure; they are susceptible to oxidation and light and may change or may even lose their properties when directly exposed to stressors. Like other sensitive, volatile, odor- or taste-intensive liquid active ingredients, they must therefore be protected from the environment or vice versa. For this protection and to simplify handling — as well as for better dosage and targeted release — these substances are therefore progressively offered and used in encapsulated and/or free-flowing forms. Various processes can be used to deliver products with a compact structure. During process development, the most suitable procedures and equipment

Optimising functional ingredients for enhanced nutrition
Fluidised bed and spouted bed processes offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned Fluidised bed and spouted bed processes by Glatt offer manufacturers almost unlimited possibilities in terms of optimised particle design and the functionalisation of ingredients, the properties of which can be fine-tuned using spray granulation, agglomeration, microencapsulation and coating. The consumer demand for fortified products is constantly growing and has been well received by end users. The form in which health-promoting probiotics, dietary fibres or antioxidants are consumed depends on both the preferences and everyday habits of the individual: some prefer sports drinks, protein bars or enriched iced tea, whereas others favour more direct dosage forms, such as effervescent tablets, sachets or capsules. However, although the manufacturing processes associated with these products present numerous challenges, a universal requirement is that functional ingredients must be stable during storage, precisely dosed, dissolve quickly or have a depot effect.

Improved performance for crop protection products Plant protection products, be they herbicides or fungicides, must be dust-free, free-flowing, stable, safe to handle + provide good redispersibility properties.
Improved performance for crop protection products
Plant protection products, be they herbicides or fungicides, must be dust-free, free-flowing, stable, safe to handle + provide good redispersibility properties. Product development usually focuses on the optimization of successful products: That means improved effectiveness and storage, safer handling and easier dosing. As well as these long-standing challenges, however, farmers and manufacturers of crop protection products are facing an increasingly fragmented market with regionally specific requirements. Due to globalisation and imbalances in the ecosystem, it is becoming increasingly necessary to control pests in a targeted manner and protect plants from previously unknown threats. Yet a growing market for organic farming means an increase in demand for biological or biodegradable crop protection agents which are obtained, for example, by fermentation processes. Industrial processing means these intermediate products are not temperature-stable and require gentle treatment at low temperatures. A further challenge is climate change: Cultivated areas in normally temperate climate regions are now exposed to weather events such

The gentle processing of highly volatile oils by fluid bed technology Sensitive raw materials, especially those that are volatile or of natural origin, require particularly gentle process conditions.
The gentle processing of highly volatile oils by fluid 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.

New fluid bed options for solvent-based processes
Glatt has expanded its range of services and capacities at the company’s Technology Centre in Weimar for trials and sample development When developing and launching new products, speed is a critical factor. However, sensitive ingredients and solvent-based processes often present manufacturers with technological challenges. In process expert and plant manufacturer Glatt’s upgraded technology centre, support from initial idea and scale-up to industrial production is readily available. At the company’s Technology Centre in Weimar, Glatt operates a unique fluid bed system that processes solvent-based products in a vacuum or using nitrogen as the process gas. As such, demand is high for scale-up tests, product sample production or short-term contract manufacturing services until the client’s own production plant has been commissioned. However, a new fluid bed granulator and coater for innovative solvent-based processes has recently become available. The batch-mode apparatus is ideal for small and medium campaigns that include frequent cleaning cycles. Special explosion protection measures, a 12

Fluid bed systems: continuous, batch, or a hybrid? Glatt series with plant solutions that enable both types of process control
Fluid bed systems: continuous, batch, or a hybrid?
Glatt series with plant solutions that enable both types of process control The discussion pro and contra continuous versus batch production is conducted as if there were only these two alternatives. However, with the Glatt series, plant solutions have long been available that enable both types of process control. A look at the requirements of two customers shows which issues are really decisive. The advantages of a continuous system are undisputed: A continuous production plant delivers very good, reproducible product quality with extremely high efficiency during continuous operation, since process interruptions due to batch changes and cleaning intervals are eliminated. Small quantities, frequent product and formulation changes, limited batch sizes, traceability or longer coating processes speak in favor of batch production. However, as soon as customer-side manufacturing conditions or specific product properties come into focus - usually the USP of every ingredient manufacturer - the really important arguments come into play: On the
