 Production of the Platform Chemical 5-Hydroxymethylfurfural (HMF) from Rural Residues and Waste for the Synthesis of the Biobased, Circular High-Performance Polymer Polyethylene Furanoate (PEF) for More Sustainable Packaging Materials

The market share of bio-based plastics is around 1%. Many bio-based packaging solutions offer improved material properties compared to conventional plastics. Skal_PEF aims to optimize the production of the bio-based plastic polyethylene furanoate (PEF) and to demonstrate its market potential through pilot applications in the Lake Constance–Upper Swabia region. PEF is not only a bio-based alternative to PET but also offers better mechanical and barrier properties, enabling a reduction in material usage and packaging solutions without non-recyclable composite materials.

In the project, PEF is produced via a synthesis based on HMF (5-hydroxymethylfurfural), which is obtained in a pilot biorefinery on the campus of the University of Hohenheim from residual biomass such as potato peels, fruit, and vegetable waste. HMF is electrochemically oxidized to FDCA (2,5-furandicarboxylic acid), which, together with bio-based monoethylene glycol (bio-MEG), is used for PEF synthesis. PEF is then processed into films and pouches and tested for suitability in food packaging. The aim is to assess ecological and economic sustainability through life cycle analyses. A focus is placed on regional value creation to minimize transport distances and reduce costs, while simultaneously building infrastructure for a bio-based industry to deliver a market-ready demonstration product with a technology readiness level (TRL) of 8 for the processes used.

The consortium hopes that Skal_PEF will promote the visibility of bio-based materials and the bioeconomy and increase acceptance of PEF. Through communication strategies and collaboration with local partners, investments are to be stimulated and practice-relevant feedback integrated in order to strengthen the industrial bioeconomy in the long term and achieve positive climate effects through the use of renewable resources.
