Question 701
3 marks · Easy
Answer and see the solution →(a)[1 mark]State one reason why addition polymers remain in landfill sites for many years.
(b)[1 mark]Name one environmental problem that can result from the accumulation of waste addition polymers.
(c)[1 mark]Give one advantage of recycling addition polymers instead of disposing of them in landfill.
Question 702
2 marks · Easy
Answer and see the solution →A country produces 1,500,000 tonnes of plastic waste each year. If 60% of it is made of addition polymers, calculate the mass of addition polymer waste produced per year. Give your answer in tonnes.
Question 703
2 marks · Easy
Answer and see the solution →Explain why burying addition polymers in landfill sites is not a sustainable solution for managing plastic waste.
Question 704
