Vacurema

Bottle-to-Bottle Application

In the VACUREMA PET extrusion process washed polyester bottle flake from post-consumer waste collection is transformed into high-quality pellets. These pellets are confirmed as 100% suitable to be reused as raw material to produce PET bottles again.

Two factors are decisive here:

  • Erema to increase the viscosity of the PET in the process

  • Extensive tests have confirmed that the reclaim, as produced with the Erema VACUREMA-technology, meets food packaging cleanness requirements.

PET bottle to PET bottle
By combining the VACUREMA extrusion system with the Erema crystallization drier, used PET bottle flakes can be turned into top quality food-contact grade PET pellets with increased IV, - at low cost -, suitable to be used 100% to make new bottles. A conventional solid state process may not be required to meet this target.


Key Advantages

  • VACUREMA-technology = "state-of-the-art" with a long reference list
  • Minimal production costs – 10 to 15 €cent/kg
  • FDA approved process, various other national approvals received
  • Same IV or increased IV (up to 0.05) in one extrusion step without solid state reactor – only one heat-up process, low maintenance.
  • Produces melt filtrated pellet
  • Simple, continuous process – "Compact production"
  • Insensitive to input moisture variations.

BTB: key parameters for classification of end product (pellet):

Safety related parameters

  • Whether they can be met depends only on the cleaning effect (ability)
    of the system and not on the input flake quality. met by VACUREMA

  • Cleaning effect of system normally checked only by means of
    challenge test. met by VACUREMA

Physical parameters

  • IV, AA, colour, pellet shape, filtration fineness: met by VACUREMA
    Normally not checked by local government/authorities

  • Result achieved and quality of pellets depend mainly on the (input) flake quality and the type of process used.
