Marking points
B1 (a) · 1 mark · Identifies Denmark as having a higher recycling percentage.
A1 (b) · 1 mark · Calculates correct difference: 65% (UK) − 3% (Denmark) = 62%.
B2 (c) · 1 mark · Gives an environmental reason for Denmark’s use of incineration (e.g., saves space in landfill, generates energy).
B3 (d) · 1 mark · States a valid advantage of recycling (e.g., saves raw materials, reduces landfill waste).
Worked solution
a) Denmark recycles 42% of its plastic waste compared to 28% for the UK, so Denmark has a higher recycling percentage.
b) Difference in landfill use: 65% (UK) - 3% (Denmark) = 62%.
c) Denmark may have less land available for landfill or prefers to generate electricity from waste through incineration.
d) Recycling reduces the amount of waste sent to landfill and saves raw materials.
