FDCA for PEF

Corbion’s BioFDCA Technology has the potential to (partially)

replace terephthalic acid used in PET, meeting unmet needs in

polymer applications:

• Enhanced gas barrier properties

• Mechanical properties

• Favorable carbon footprint/LCA

• 100% Biobased

Biobased/durable production capacities & markets

• 6 x growth driven by PET bottles • PET30 = 30% biobased • Growth of emerging drop-ins in

2019, such as PEF. • 75% of markets: rigid packaging

and textiles.

Biodegradable production capacities & markets 2014

• 100% growth driven by PLA & biodegradable polyesters (i.e., PBAT, PBS)

• PHA growth promising • Flexible & rigid packaging +

agriculture & horticulture >75% • Functional benefits drive steady

growth in maturing markets

©

1. 100% biobased

2. Biodegradable -durable - recyclable

3. a versatile plastic - Injection molding, Fiber, Film, Blow molding, TF

4. Excellent breathing properties

5. a stiff and rigid polyester, much like PET – also replacing PS

6. A Tg of 55 C – unless crystallized

7. Feed stock efficient - < 1,5 kg of sugar for 1 kg of PLA (BioPE 4 kg)

8. Low Carbon footprint

9. Available - in large volume!

10. Development Potential by use of the isomers of Lactic Acid: L and D
