Avantium has focused its efforts on the polyester polyethylene-furanoate (PEF), which is an analogue of polyethylene-terephthalate (PET).

PEF could replace PET in typical applications like films, fibers and in particular bottles for the packaging of soft drinks, water, alcoholic beverages, fruit juices food and non-food products.

Avantium

Avantium is a Dutch technology development and licensing company with extensive experience in catalysis.

Superior functional properties

Avantium’s research has proven that PEF bottles outperform PET bottles in many areas, particularly barrier properties (the ability of the polymer to withstand gas permeability through the bottle).

PEF’s ability to seal out oxygen, for example, results in longer-lasting carbonated drinks and extended shelf life. Moreover, PEF makes certain packaging coatings redundant, like the coatings used on bottles to keep beer fresh.

CocaCola and Danone are already partners.

PEF’s ability to seal out oxygen, for example, results in longer-lasting carbonated drinks and extended shelf life. Moreover, PEF makes certain packaging coatings redundant, like the coatings used on bottles to keep beer fresh. In terms of thermal properties, PEF is widely considered more attractive than PET due to its superior ability to withstand heat (expressed in the glass transition temperature or Tg) and process-ability at lower temperatures (expressed in the melting temperature or Tm).

Superior barrier properties:

  • PEF oxygen barrier is 10 times better than PET
  • PEF carbon dioxide barrier is 4 times better than PET
  • PEF water barrier is 2 times better than PET

More attractive thermal properties:

  • The Tg of PEF is 86°C compared to the Tg of PET of 74°C
  • The Tm of PEF is 235°C compared to the Tm of PET of 265°C

Recycling PEF bottles

Avantium has demonstrated that PEF can be recycled in very similar ways to PET recycling.

Stage I: PEF in rPET stream

In the transition period following the launch of PEF bottles, the amount of PEF in the total PET stream is relatively small. PEF bottles are likely to be recycled in the PET recycling stream (rPET). The outcome of preliminary tests (using ASTM test protocols) shows that PEF has no material effect on the mechanical and physical properties of PET, such as strength and impact. Avantium is currently working with brand owners and the recycling industry to further integrate PEF into the PET’s recycling stream.

Stage II: PEF to PEF recycling

Once PEF is produced in larger volumes it is likely it may become economically more attractive to separately recycle PEF. Avantium is currently working with brand owners and the recycling industry to establish a PEF to PEF recycling infrastructure in the future.
