2. Plastic pollution impact on our food

3. Bruxelles
Mexico cityHong Kong
New York city
Can we blame on this reaction?

4. Public Opinion:
the consumers influence and its «victims»
PE, PP, PS

5. Pic-nic time: healthy food every time

6. Because food has an impact

7. For a growing population…

8. How we do packaging makes the difference

9. Conclusion: banning is not a solution
9
https://en.wikipedia.org/wiki/Population_growth
Food saving is mandatory

10. What about textile?
Can we ban it?

11. Can we reduce the use of clothes?
Not always

12. What packaging and textile have in commun?
They are complicated materials!
Thermal valorization and landfill are the only solution for their end-of-life

13. Demonstration of that!

Plastic – the facts 2017 PlasticEurope Impact on recycling rate and energy recovery

14. Downcycling and PET numbers

Waht can we achieve?

17. The monomers purification: a closed loop itself
31/08/2020 DEMETO (H2020-SPIRE-09-2017 Project Number 768573)
• gr3n process it is
circular itself
• The chemicals are
produced on site from
the reaction by-
product: NaCl
• The input of the
process are PET scrapes
water and energy
• International Patent
(EU, China)
• New patent filed in Nov
2019

18. Same PET from different feedstcks:
packaging &textile

19. Polycotton, ≈60/40 (PET/Cotton)

PET and Cotton fingerprints

20. Polycotton: 100% Cotton recovered & 100%PET

Suitable for Rayon!
ONLY Cotton fingerprints!

21. Home textile
Home textile:
≈ 65/70 % PET
≈ 25/30% Poly Urethane
≈ 5% Others

23. r-PTA ANALYSIS RESULTS

24. Production costs: relative distribution
The cost of the monomers is competitive with fossil
The € values are upon NDA

25. Starting points of DEMETO: the heritance of
Symbioptima and the process scale-up
25
• The depolymerization machines scales and….the purification process scales up
~1 kg/h
~10 kg/h
~100 kg/h

26. DEMETO plant: depo and monomers
purification

27. DEMETO plant: salt recovery, electrolysis

28. Creating a technology is not placing it:
the Industrial Advisory Role, IAB
EU PROJECT THE INDUSTRIAL ADVISORY BOARD

29. The environmental impact and the social costs
of CO2
82 million tonnes PET/y 2.28 tonnes CO2/ tonnes PET
26.3 B$/y CO2 cost
(140 $/tonnes CO2)

30. -67.4% -63.7%
gr3n reduction compared oil based
-16.7 B$/y of social costs saved

31. Real case study: current Situation,
