Fibre Save is an Interreg project (Vlaanderen-Nederland) that aims to upgrade paper and cardboard waste into PHB, a biobased plastic, using innovative fermentation technologies. Within Fibre Save’s professional network, the project partners will apply their specialized expertise to develop and test PHB prototypes and products for multiple sectors, using a range of production techniques. Fibre Save contributes to the transition towards a circular economy, with lower CO₂ emissions, fossil-free materials, and high-value recycling while supporting the development of an innovative, cross-border value chain.

From Waste to Bioplastic: The Fibre Save Flow

• Waste as Feedstock:
  Renewi and VPK Paper provide diverse paper and cardboard waste streams, which are rich in sugars and ideal for bioconversion.
• Fermentation & Scale-Up:
  At Bio Base Europe Pilot Plant (BBEPP), microorganisms ferment the sugar-rich waste into PHB and its variants. Lab-scale processes are scaled up to semi-industrial levels.
• Application & Validation:
  MNEXT develops and tests PHB-based prototypes across multiple sectors. Meanwhile, PBM  investigates PHB’s biomedical potential, pushing the boundaries of its use.
• Market & Environmental Assessment:
  POM East Flanders conducts economic feasibility studies and performs LCA hotspot analyses to evaluate the environmental impact of the entire value chain.
• Communication & Engagement:
  Pack4Food leads stakeholder dialogue and outreach, ensuring companies across the value chain are actively involved and informed.
