From citrus peel to PEF plastics – sugar-acid-based high-yield FDCA

11 Nov 2021
The Greener Manufacturing Show Conference
The shift from fossil-based to renewable plastics requires novel ways of producing monomers. New technologies developed at VTT enable the use of pectin-containing agricultural waste, such as citrus peel and sugar beet pulp, as raw material for renewable monomers like FDCA. Aldaric acids obtained from the waste streams are stable intermediates for the production of FDCA (2,5-furandicarboxylic acid), one of the monomers of PEF, offering significant advantages compared with common routes. The stable aldaric acids bring high process yields and thereby enable an overall cost-efficient manufacturing platform. PEF is a renewable alternative to fossil-based PET with superior barrier properties. Utilizing pectin-containing waste streams opens up new possibilities for the circular economy of plastics.
