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!
