Processing of biodegradable products
Processing of biodegradable products makes very high demands on the compounding process because of the variety of possible base polymers and the great differences in the formulation mixtures. Every process step in a biodegradable products processing plant must be adapted exactly to the desired mechanical properties of the end product.
We have built up a comprehensive know-how for the processing of biodegradable products with numerous implemented plants. Our specialists also benefit from our years of experience in the fields of cooking extrusion and plastic compounding which we gathered under our former name Werner & Pfleiderer.
Our twin screw extruders are the heart of the processing plants for biodegradable products. The modular structure of the process section enables individual adaptation to every application so that optimal product qualities are achieved. Apart from the extruder, we also provide the entire plant periphery from the raw material feeding to pelletizing and drying of the pellets. Alternatively, it is possible to produce biodegradable products by direct extrusion.
