“In difficult economic times, recycling is a reason to invest”

ABS is a material for esthetically and mechanically demanding applications in the automotive industry, electronic housings, household appliances, and medical technology.

ABS is particularly in demand for electrical and household appliances.

The increasing demand for recyclates and the shortage of food-grade PET flakes pose challenges for batch quality and color consistency.

Repi offers various additives for recycling PET, which can be used, for example, to prevent the material from darkening.

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.
