Possibilities

High-quality standard fertilizer as a product.

The cost-effectiveness of phosphate recycling processes depends, in addition to the process costs, in particular on the possible revenue generated by the manufactured products. Alternatively discussed P recycling methods, whether by thermochemical digestion of sewage sludge, thermochemical or thermoelectric maceration of sewage sludge ash or by means of wet chemical processes, are not economical under the current market conditions.


The basic problem is that no standardized fertilizer products are produced. The nutrient value of recyclates in monetary terms cannot be equated to the market price, since it is crucial whether the nutrients are present in a soil and plant-specific composition and are well-defined and readily available. Since this does not apply to any of the known processes, these recyclates will be regarded as waste products with a correspondingly low value for the foreseeable future.


Even the processes that generate phosphoric acid are currently not cost-covering, since the process costs are much higher than the current market price of phosphoric acid. This is due to the complex process itself, the high costs of chemicals and the costs of disposing of waste materials.


PHOS4green results in soil-specific and plant-specific standard fertilizers that meet today's standard for fertilizers in terms of quality and performance. These products can therefore be used directly in agriculture without further processing. No changes to the operating procedure. No changes to the existing technology or the output quantity. Business as usual compared to the previous standard products. As a result, a fair market value can be achieved with these products.

SUSTAINABLE FULFILLMENT OF THE P-RECYCLING OBLIGATION

Transfer of sewage sludge ash to ordinance-compliant fertilizer (DüMV)

The obligation to recycle phosphate-containing residues is now set by law. Following pre-defined transition periods, most of the previous disposal routes are eliminated.


Phosphorus recycling processes that sustainably reintroduce the element of phosphorus into the economic cycle are currently sought after. Thus the demand for processes to produce the phosphorus products needed by the market at competitive prices is rising. If no marketable products are produced, then the process has to be subsidized. Every recycling process should aim to recycle all substances as fully as possible without, in turn, generating substantial environmentally unfriendly waste.


Glatt combines these requirements for sustainability and recycling with the PHOS4green process, which is already profitable under the current market conditions.

HIGH FLEXIBILITY WHEN IT COMES TO RAW MATERIALS AND PRODUCTS

Guarantees long-term profitability in volatile markets

Both the commodity markets and the fertilizer market are highly volatile. Sometimes significant fluctuations in availability and price can occur. To ensure long-term profitability, a process must be able to react as flexibly as possible to such fluctuations and, if necessary, be able to adapt to changing market needs.


With PHOS4green, a whole range of different P, NP, PK and NPK fertilizers can be produced. This allows you to respond flexibly to fluctuating market needs, raw material availability and market demand.


In addition, the degree of chemical and mineralogical variation of sewage sludge ashes at different incineration sites, but also over time in a location itself, is very high. Complex and coupled dissolution, precipitation and extraction processes, as with other P recycling processes, are very sensitive to fluctuations in the raw material. Stable process management is therefore hardly possible, and is usually at the expense of optimum phosphorus yield, operating costs and product quantity.


With PHOS4green, the fluctuating raw material composition of the ash can be balanced out by simply adapting the other additional components, for example the nutrient components.


PHOS4green is our solution for ensuring consistent quality.

You can easily adapt the recipe to balance fluctuations in the composition of the ashes.

COMPACT, DUST-FREE, WATER-SOLUBLE GRANULES

High abrasion resistance for easy handling without material loss

Various combinations of active ingredients can be set up through spray granulation in the fluid bed apparatus with optional subsequent coating. The granulates thus manufactured have a dense surface with a high degree of abrasion resistance. Advantages for practical applications are improved product properties and the reduced occurrence of unwanted signs of drift during output. Furthermore, the solubility of these kinds of granulates are readily adjustable to the demands.
