Phos4green: Fertiliser from phosphorus-containing ashes - Waste-free process using fluidized bed spray granulation

Fertiliser from phosphorus-containing ashes - Waste-free process using fluidized bed spray granulation

More than 90 °/o of the world's phosphorus reserves are outside Europe. For this reason, Germany regulates the recovery of phosphorus by law. As the amended Fertiliser Regulation restricts direct soil-bound recycling of sewage sludge containing phosphorus, many disposal companies will be forced to establish alternative recycling methods. Phos4green is a two-stage method that extracts phosphorus from sewage sludge ash and converts it into ready-to-use fertiliser granulates.

Phos4green: recovery technology that releases phosphate from sewage sludge ashes and converts it into ready-to-use fertilizers

Phosphate recovery technology Phos4green is the "Rising Phoenix"

Jan Kirchhof, Glatt Ingenieurtechnik, Germany, presents a recovery technology that releases phosphate from sewage sludge ashes and converts it into ready-to-use fertilizers.

By using PHOS4green, including spray granulation in a fluidised bed, domestic phosphorus sources can be used and marketable fertilizers can be produced directly from sewage sludge ash. The process is suitable for the production of soil/plant-specific nutrient fertilizers that comply with the German Fertilizer Ordinance in this example. Of course, the production process precedes the sale. This can be done with a Glatt system or by commissioning a contract manufacturer. As the process is already established, contract manufacturing enables immediate implementation if a recycling process is prescribed by law or is required to protect the environment and avoid waste.

The potential of fluidized bed plants for the production of special fertilizers

The potential of fluidized bed plants for the production of special fertilizers

Dr.-Ing. Michael Jacob, Head of Process Technology Food, Feed & Fine Chemicals, Glatt Ingenieurtechnik, Germany, explains why fluid bed systems are key to producing specialty 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. In addition, fluidised bed processing, which has been in use since the 1960's, is one of the most effective drying techniques. The technology is particularly suitable for the manufacture of products that require safe handling and dosing – whether this is a high performance fertilizer, an artificial fertilizer, or a standard fertilizer based on regular components or recycled raw materials. One of the most interesting advantages of fluidised bed technology is that all of the necessary production steps can be carried out in a single continuous process without interruptions or machine changes.
