Starlinger recycling technology

 

recoSTAR PET extrusion (flakes to pellets)

PET flakes are heated and dried in a two-stage process by means of hot air and dry air, or under vacuum. The special design of the dryer outlet results in center flow prevention, consistent residence time and FIFO processing. This ensures decontamination for food contact applications and ideal preparation for the extrusion process with maintained IV level (recoSTAR PET FG) or with IV increase (recoSTAR PET FG+).

A choice of filtration and pelletising systems are available. Once installed, the unit can be equipped with an SSP reactor (iV+) to increase viscosity and decontamination levels.
 

recoSTAR PET with Starlinger iV+ technology (flakes to SSP pellets)

The Starlinger iV+ recycling process for PET food contact applications consists of two main steps: the continuous extrusion process, and the semi-continuous solid-stating process either before or after the extrusion step (recoSTAR PET iV+). It turns post-consumer PET flakes into pellets that meet the highest requirements.

Special FIFO design ensures consistent reaction parameters, adjustable IV increase, as well as highly effective decontamination for food contact applications.

With recoSTAR PET iV+ Superior the combined decontamination steps of both the flakes in the vacuum dryer upstream of the extruder (FG+) and the pellets in the SSP reactor downstream of the extruder (iV+) result in the highest possible quality of pellets. This superior decontamination process reduces acetaldehyde (AA) and volatile contamination (VOC) to a minimum.
