The use of TPE materials with recycled content increases the sustainability of vehicles. They are also used more and more in the interior.

The selection of high-quality recyclate enables their use in demanding automotive applications.

The quality of recyclates is seen as too low. Improvements are possible by using additives, as was shown by the exchanges during the Forum Plastic Recyclates.

Quite clearly, the central theme of this year’s conference  was additives for recycling materials.

Using the latest technological advances in flake sorting helps bridge the gap between supply and demand.

Mixed plastic waste: With about 180.5 million t polyolefins make up the lion‘s share of annual plastics production.

Quantum Leap in Recyclates Quality

The stabilization of used plastics is costly. Online measurement during compounding allows for stabilization directly in production.

Plastic waste often has a very different stabilizer content. This must be precisely determined in the recycling process.

IR-Fresh Minimizes Odors in PCR Granulates

Plastic recycling: Kreyenborg uses infrared technology for the reduction of unpleasant odors in plastics.

In order to obtain high-grade plastic recyclates from plastic wastes, odorous substances that have migrated into the material during its service life, must be removed. For a longer time, Kreyenborg’s plastics recycling team has been working on solutions for decontamination of PCR-PET, crystallization, drying, and heating of bulk materials using infrared technology.

The further development of these technologies is called IR-Fresh – a modular system for the efficient reduction of unpleasant odors in plastics.

In the first process step, an infrared module installed above the material bed heats the material quickly and directly to the optimum temperature level for the plastic in question. In this process, the continuous rotation of the drum ensures a homogeneous mass flow with a defined dwell time (applying the first-in/first-out principle). By means of the rotating and mixing elements integrated in the spirals, the material is continuously mixed in the drum with constant surface exchange. Combined with controlled heating, this ensures considerable odor elimination, even within a very short residence time.

In the second process step, the remaining odorous substances in the regrind or granules are removed by a thermal-physical cleaning process in the IR-Fresh Conditioner. This insulated hopper keeps the material to be decontaminated within a temperature range that is ideal for the decontamination process by means of a hot purge-gas. Good results for deodorization and decontamination can be achieved through the interaction of the main process parameters of airflow, temperature, and residence time.

Through its modular design, process can be used continuously in two stages both for regrind – before the extrusion process – and for granules – after the extrusion process. Likewise, it is also possible to integrate the IR-Fresh Conditioner as a sole process step in the process chain, or to operate it as a stand-alone solution continuously, as well as discontinuously. The system presented is also suitable as a retrofit solution for integration in existing plants.
