PET-Extrusion System VACUREMA

The Erema VACUREMA technology for
PET processing and PET recycling

This unique, well proven and extremely flexible technology can process PET materials and any blends of materials coming along

  • in the form of virgin pellets, post consumer bottle flakes, preground preform flake, preground cut out frames from thermoforming, precut fibre waste, and others,
  • without external upstream crystallisation and without upstream predrying,
  • in various bulk densities,

into melt filtrated, virgin-like pellets or directly into end products such as sheet, fibre or strapping.

Different plant concepts can be configured depending on customers' individual requirements regarding required IV and required degree of decontamination.

The basic VACUREMA technology

 … works with a (patented) single reactor under vacuum directly feeding a sturdy, insensitive single screw extruder system. Suitable for applications such as PET fibre processing and inline thermoforming sheet extrusion. Product FDA approved.
Beginning with e.g. bottle flakes
the material is brought into the VACUREMA reactor/extruder combination via vacuum lock. Appropriate holding time in very high vacuum/high temperature atmosphere effectively removes contamination (volatile matter) from the PET flake, and minimises residual moisture and IV-loss. The PET flake is continuously fed, still under vacuum, directly to the extruder. In the extruder the PET material is plasticised and homogenised and then fed to a fine filter with integrated, automatic self-cleaning system. In the filter residual solid contamination down to very small particle size is separated from the PET melt. The continuous extrusion process enables optionally continuous online IV monitoring/recording of the processed PET melt.
The result is clean, food-contact grade, optionally crystallised pellets with high IV levels that can be reused directly to produce high quality products.
FDA category "C" approved.

VACUREMA technology with upstream crystallisation dryer: “Double Step VACUREMA technology”

 This process technology uses a crystallisation dryer with or without vacuum admission upstream of the VACUREMA-reactor. Suitable for Bottle-to-Bottle recycling applications, where a modest IV increase (crystallisation dryer without vacuum admission) or a
considerable IV increase up to five points (crystallisation dryer with vacuum admission) is required. FDA category "C" approved. PepsiCo approved. Degree of possible IV increase depends on input flake quality.

VACUREMA technology in combination with downstream SSP process

Suitable for “Very high IV-increase” recycling applications. Virtually any required IV increase can be achieved. Produces high quality, crystallized and melt filtrated pellet. Due to VACUREMA process upstream of SSP, SSP process can, depending on individual targets, increase throughput or can be designed smaller (reduced investment). FDA category "C" approved.
