Environmental Effects of Addition Polymers"

Question 1

Why are polymers useful?

Answer 1

= polymers are unreactive
= non-polar, strong

Question 2

What is an environmental problem of additional polymers?

Answer 2

= non-bio degradable
= not broken down my microgaisms in the environment
= pollute for decades >

Question 3

What is another enviromental problem with additional polymers?

Answer 3

= use of crude oil- non renewable (polymers are made from alkenes)
= needs to be transported and refined: requires energy
= addition [polymers are used in large amounts: occupy space in landfill
=

Question 4

How can we reduce the effects of using polymers?

Answer 4

= waste polymers can be combustion- generates energy
= can release harmful chemicals
= when pvc is combusted, procuces hcl gas produced, corrosibe andremoved imediatleu

Question 5

What is the second way of reducing the effects of polymers?

Answer 5

= recyled into new products
= reduce use of crude oil
= landfill space

Question 6

What is feedstock recycling?

Answer 6

= waste polymers are converted back into simpler hydrocarbons
= cracked and converted to different plmers
= wast poroducest does not need sorting
= converts one polymer to one other polmer
