Upscaling of a fermentation process for PHB production

  • 2017


Demonstration of a process for the production of PHB (polyhydroxybutyrate) from industrial food waste (cereal residue), including:

  • Feedstock conditioning
  • Enzymatic hydrolysis
  • Hydrolysate recovering
  • Fermentation
  • Biomass separation
  • Pellet recovery and delivery to customer


  • Project coordination: Whole process adaptation including equipment selection from vendors (decanter, centrifuge).
  • Monitoring of the process and data recording of relevant parameters.
  • Plant operation
    • 1st stage upscaling to PILOT plant – 100 -200 L
    • 2nd stage upscaling to DEMO plant: 1.000-3.000 L
