Odour optimised, energy efficient, recyclable. And for specific applications: super clean and food contact compliant.

Post consumer recycled pellets of the future can do more. Get more out of your material stream with featuring digital assistance systems. More quality, more productivity. For a beter end product. Take the new energy saving dual filtration solution (automatic belt melt filter+back flusher filter), for example, as well as refresher anti odour technology.

Heavy contamination and mixed. damp material, and different colection systems often make recycling post consumer plastics a complex challenge. To obtain high-quality secondary raw materials from thin-walled LDPE films or thick-walled PE or PP regrind requires particularly reliable stable processes and plant that is robustly constructed. Maximum performance with high- quality processing is what is needed, as offered by the recycling systems from our solutions that are designed for post consumer waste.

1. Ideal material preparation in the preconditioning unit

Cutting, homogenising, heating, drying, compacting, buffering and dosing – in a single stage. The dynamically controlled Preconditioning Unit (PCU) is multitalented. It prepares the plastic ideally for the extruder and sets the course for consistently high end product quality already at the beginning of the recycling process.

2. Gentle melting, low shear stress

Because it has been preheated in the PCU, the material in the extruder reaches the required melt temperature more quickly. This shortens the extrusion process (shorter extruder), the time taken to melt the material, and the time it spends in the extruder.

3. Highly efficient filtration

Thanks to the low shear stress, impurities are hardly broken up and are therefore large enough to be removed easily and efficiently by the belt melt filter before the melt is homogenised.

Against odour and discolouration:

The early removal of impurities such as cellulose (wood, paper), rubber and silicone means that they can no longer outgas or overheat later and no unpleasant odours or discolourations develop, which is a decisive quality bonus for the melt.

4. Perfect homogenisation

Greater homogenisation efficiency downstream of filtration an dupstream of degassing enhances the subsequent degassing performance and improves the characteristics of the melt.

5. Powerful degassing

Highly efficient triple degassing (in real full-vacuum state):
The first stage of degassing takes place at the start of the process in the PCU. Step two is second extruder degassing, which is made possible by the optimised screw design.

..after melt filtration (in real full-vacuum state):
The final triple venting degassing at the extruder is particularly effective and removes gas inclusions which are still present from the melt.
