Recycling and processing of shredder heavy fraction
Since 1991, the bi-directional dense medium separation technology for the recycling of automobile and industrial wastes is being used. For many years a principle client in this regard has been the Group Galloo. Group Galloo owns currently 50% of the AD REM shares. At first the Galloo staff was not convinced that a carrot separator could compete with the classical dense medium separators on the market at that time. So they set up a trial on +12 mm automobile shredder residue, running half of the test material through a conventional drum and the other half through this modified bi-directional carrot separator.
The results here were quite dramatic: the conventional drum showed 15% misplaced material (either floats in sinks or sinks in floats), whereas the bi-directional separator showed less than 0.1% misplaced material. Since the bi-directional drum was approximately 150 times more accurate than the conventional drum, Group Galloo never looked back. This aggressive and forward-looking company went on to set up four of the largest and most profitable recycling centers in the world: one at Halluin (France), two in Menen (Belgium), and a final one near Charleroi (Belgium).
Other separation technologies
In 1991 the best technology at the time in Europe for separating non-ferrous metals was the eddy current separator. These eddy current separators will not eject all of the heavy metals out of the non ferrous shredder residues. A organic drop is created with still a significant amount of heavy metals. When processing eddy current drops, the added value of the end products created with the Ad Rem separation equipment will easily compensates the processing costs . Even today with the coming of the finders, the optical-, X-ray, and XRF sorters the drop fractions of these instruments can be treated using the Ad Rem installations, and still these fractions will generate a significant added value coming from the metals that are still in the drop fraction. With the Ad Rem equipment fractions of organic materials are generated that can be further recycled or reused as a fuel for cement kilns.
From 1991 up till today Galloo does this type of processing for its own shredders and for many other shredder companies, proving the high quality of the separation technology and the high return on investment of the Ad Rem separation equipment.
