  4. 4. SHEET 4 Vision of the Dutch PBI "The paper industry is the centerpiece of a Biomass-based Circular Economy.We make the most out of Biobased raw materials and hereby reduce energy consumption and CO2 emissions and increase the added value and customer value of products and services. Our people make the difference." CEPI – EFPRO Early Stage ResearchersWorkshop Nov 2015
  5. 5. SHEET 5 Vision of the Dutch PBI Vision 2020 is to have 100 % closed product Biobased cycles: • Full use of raw materials • 100 % positive reusability or recyclability of all components CEPI – EFPRO Early Stage ResearchersWorkshop Nov 2015

  10. 10. SHEET 10 PHA • Bioplastic from the family of polyesters (e.g. PET) • Good moisture and gas barrier • Excellent film forming and coating properties • Good biodegradability
  11. 11. SHEET 11 Opportunities with PHA CEPI – EFPRO Early Stage Researchers Workshop Nov 2015 • Close water loop without adding biocides • Solve problem of COD accumulation • Savings from closing the water loop • Application in paper products - biodegradable packaging • Produce products with added value

  15. 15. SHEET 15 Summary:Towards full use of all components dissolved ash / plastics fibers biomass Full use of biomass: - (cellulose) fibers - hemicellulose - lignin - Proteins, sugars, fats - Nutrients, etc. On location or elsewhere. Reclamation of the dissolved fraction: • Biopolymers (PHA, alginates) • Waste heat and energy • Clean water Reclamation of the solid fraction: • Separation of plastics and metals from rejects • Reclamation of inorganic fillers and fines Reclamation of fibers: • Paper for Recycling • Fibers from papermaking side streams • Fibers from materials previously considered as waste
  16. 16. SHEET 16 Conclusions We are a leading industry in resource efficiency but there are still many more possibilities ahead to convert waste from Cost -> Profit Many technical possibilities ahead; economics are coming… CEPI – EFPRO Early Stage Researchers Workshop Nov 2015
