renewable to polymers Flashcards
Fossil- based plastics-where they derive from? Give examples.
from petroleum, coal or natural gas, like: polyethylene, polypropylene (durable)
polycaprolactone, Polybutylene Adipate. (biodegradable)
Bio-based plastics-where they derive from? Give examples.
From biomass, like: bio-polyethylene, bio-polyamides (durable),
polylactic acid, polyhydroxyalkanoates (bio degradable)
Is it true that durable bio based plastics are not degradable?
yes
Is it true that Fossil-based biodegradable plastics are less persistent in nature?
yes
Name 2 bio-degradable biobased plastics
PLA-polylactic acid
PHA (Polyhydroxyalkanoates)
What does PET stand for?
polyethylene terephthalate
Which of these are fossil-based?
polyethylene, polypropylene,
polylactic acid, polyhydroxyalkanoates, starch blends, polybutylene Adipate
polyethylene, polypropylene, Polybutylene Adipate
Why PET (polyethylene terephthalate) is not a bioplastic?
its neither biodegradable (persists in environment) , nor biobased (fuel)
Is it true that Not all bio-based plastics are biodegradable
Not all biodegradable plastics are bio-based?
true
Where are bioplastics applied?
Packaging, agriculture- fertilizers encapsulated in biodegradable coatings,
kitchenware, shampoos, bottle packaging,
Textile-clothing fibers
Car parts
Components for laptops, phones.
Compare PEF and PET
PEF-polyethylenfurfurate VS PET polyethylene terephthalate
* PEF is bio based, while PET is fossil-based,
* Renewable feedstock, non-renewable feedstock
* Both are fully recycable
* PET is persistant in ecosystems, while PEF is not (biodegradable)
