“In the near future, you may buy orange juice in bottles that are made out of orange peel. VTT’s novel technology provides a circular approach to using food waste streams for high-performance food packaging material, and at the same time reducing greenhouse gas emissions,” shares Professor of Practice Holger Pöhler from VTT”.
PET (polyethylene terephthalate) and other polyesters are being widely used in food packaging, plastic bottles and textiles. The annual production of PET products is estimated at 30 million tonnes. Replacing fossil-based PET with plant-based PEF (polyethylene furanoate) polymers can lower the carbon footprint of the products by 50%.
Moreover, the barrier properties of PEF plastics are better than PETs, meaning that the food products have a longer shelf life. PEF is a fully recyclable and renewable high-performance plastic. Therefore, it opens up possibilities for the industries to reduce waste and to have positive impact on the environment.
VTT’s technology has significant advantages for making bio-based PEF plastics. The technology uses a stable intermediate for the production of FDCA (2,5-furandicarboxylic acid), one of the monomers of PEF, which enables a highly efficient process. In addition, utilising pectin-containing waste streams opens up new possibilities for the circular economy of plastics.
VTT’s unique scale-up infrastructure from laboratory to pilot scale ensures that this new technology will be brought to a technology readiness level that will allow polymer manufacturers’ easy transition to full scale.
VTT has patented the technology, and the research has been published in the scientific journal Green Chemistry on 7 December 2020: A unique pathway to platform chemicals: aldaric acids as stable intermediates for the synthesis of furandicarboxylic acid esters
