FDCA and plantMEG™ together make a 100% plant-based plastic PEF


PEF is a 100% plant-based, recyclable polymer with a wide range of applications such as packaging, textiles, film, and many more. PEF has a powerful combination of environmental features and superior functionality. It shows improved barrier properties for carbon dioxide (CO2) and oxygen, leading to a longer shelf life of packaged products. It also offers higher mechanical strength, which means that thinner PEF packaging can be produced and fewer resources are required. In combination with the plant-based feedstock, these added functionalities give PEF all the attributes required to become the next-generation polyester.


Superior barrier properties:

  • PEF’s oxygen barrier is 10 times better than PET
  • PEF’s CO2 barrier is 6 to 10 times better than PET
  • PEF’s water barrier is twice as good as PET’s

More attractive thermal properties:

  • The Tg (glass transition temperature) of PEF is 86°C compared to the Tg of PET of 74°C
  • The Tm (melting point) of PEF is 235°C compared to the Tm of PET of 265°C

Addressing the need for a circular new plastics economy

Renewable: PEF is plant-based instead of fossil-based and has a 50-70% lower carbon footprint (source: Copernicus Institute at the University of Utrecht (Eerhart et al. 2012)
Reduce: PEF is superior allowing light weighting by more than 20% in line with European legislation

Reuse: Performance potential PEF in reuse under development

Recycle: PEF has a proven fit with existing sorting and recycling facilities and can substitute barrier materials and coatings in multi-layer packaging solutions which currently are challenging to recycle

Degradable: PEF is designed for recycling and reusing and therefore it fits perfectly in a circular economy. If human behavior results in unplanned and undesired leakage of PEF into our environment, first results of tests by Organic Waste Systems (OWS) (Gent, Belgium) show that PEF degrades much faster than PET under industrial composting conditions (250-400 days with air/oxygen at 58°C in soil). Avantium is investigating, together with the University of Amsterdam, the degradability of PEF under ambient conditions in a multiyear field trial.

High-value applications

Multilayer bottles

PEF as barrier layer providing performance and enabling recycling


Single layer bottles

Single layer PEF in small bottles for soft drinks, beer and juice, replacing glass bottles, aluminium cans and  multilayer bottles, enabling closed-loop recycling


PEF film in recyclable flexible packaging or as film used in electronics applications (e.g. displays)



The main building block for PEF is furandi­carboxylic acid (FDCA). Given the huge potential of FDCA, industrial production of this building block has been pursued and researched for over 100 years, without success. As such, FDCA has been called ‘the sleeping giant’. Avantium believes that our YXY® Technology can finally unlock the full potential of FDCA. The FDCA monomer offers exciting opportunities to create a wide range of polymers. These include polyesters, polyamides and polyurethanes, as well as coating resins, plasticizers and other chemical products.


PlantMEG™ is an important chemical building block for PET or PEF resin for bottles and packaging; fibers for apparel, furniture and automotive; and solvents (e.g. paint and coatings) and coolants.

The use of plantMEG™ will provide brands with a sustainable, recyclable, and innovative ingredient capable of attracting environmentally conscious consumers.
