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. 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

Polyhydroxyalkanoates (PHA)
CEPI – EFPRO Early Stage Researchers Workshop Nov 2015

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. 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

12. SHEET 12CEPI – EFPRO Early Stage Researchers Workshop Nov 2015
Alginates (Alginic acid)

13. SHEET 13
Alginates
• Anionic polysaccharides present in brown algae
• Excellent surface sizers and enhance grease resistance, oil
resistance, and printability
• Interesting film forming and coating properties
CEPI – EFPRO Early Stage Researchers Workshop Nov 2015

14. SHEET 14
Opportunities with Alginates
• Close water loop without adding biocides
• Application in paper products – sizing agent, coating...
• Product with added value
• Savings from closing water loop

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. 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…
