RDF production with Stabilat®

Utilise waste instead of dumping it!

By using Herhof’s Stabilat® technology, the volume of residual waste is organically reduced through dewatering. At the end, the water content lies distinctly below 15 percent, which significantly improves the mechanical separability of the material. This distinguishes Herhof's Stabilat® process from all other conventional treatment techniques. Reusable material is separated during the process and can be sold as a genuine high-quality raw material and returned into the material cycle. The remaining organic waste fraction is pressed into hygienic, nearly odour-free energy resources known as pellets.


Herhof Stabilat® process in 3 phases

1. Processing
Extraneous matter and harmful substances are removed from the waste and the latter is then shredded to a maximum grain size of 250 mm and then transported via a fully-automatic crane system into the Herhof bio box.

2. Stabilisation
In the Herhof bio box, the waste is dewatered through biological means. This is the vital step to the subsequent pure source separated break down of the waste mixture into reusable material and energy as well as for the storability of the fuel generated.

3. Inert separation
This means the removal of the mineral fraction (stones, glass, ceramics) and the metals, separated into ferrous and non-ferrous metals.


The core of our ideas: The Herhof bio box

After the Herhof bio box is filled, the waste mixture is dewatered in a seven-day maxi-mum aerobic composting. The humidity is discharged with the air in circulation. This is done with the natural organic heat that develops during composting. At the end, the waste mixture contains less than 15 percent moisture. That is the ideal condition for separating it very efficiently into reusable material and energy resources.

At the same time, we strictly observe EC emission limits or even go below them markedly. That is why the entire material flow within the system takes place via encapsulated, fully automatic transport systems. The exhaust air created in the process is extracted and purified.

The final step is the pure source separation into mineral and metal fractions as well as the separation of the combustible elements in form of a new fuel.
