bioplastics
1.
What is a bioplastic?
2.
Same period
2000s
1930
Non-food plastic materials
Biosourced polymer objects
Production growth of bioplastics was slowed down
1908
Jacques Edwin Brandenberger
Henry Ford
Invention of cellophane
A little bit of history...
polybutylene succinate
bio-polyethylene
polylactic acid
3.
Of fossil origin & biodegradable
BIODEGRADABLE & biosourced
THE non-biodegradable & biosourced
How many types of bioplastics?
4.
Degradation time of a bioplastic
5.
Composition
6.
From plants, starch, vegetable oil or glucose derived from starch
Renewable
Made of plant carbon
BIOPLASTIcs
Made of fossil carbon
VS
plastic
Biomaterials production is increasing by 60% per year.
7.
According to IUCN, 7 kg of plastics discarded every second
→ 500 to 1000 billion tonnes of plastic bags per year→ Petroleum-based, non-biodegradable waste = 400 years of decomposition
Why ?
8.
Advantages and disadvantages of bioplastics
9.
Evolution of bioplastics over time
Thank you for your attention!
