Methods of Municipal Solid Waste Management in Da Nang, 2024
Methods of Municipal Solid Waste Management in Da Nang, 2024 (%)

Percentage breakdown of the methods used to manage municipal solid waste in Da Nang, Vietnam, in 2024: landfill, recycling, incineration, composting, export for recycling, and chemical/hazardous treatment.

Band 6.5

This 6.5 answer correctly reports all six percentages but relies on repeated, simple phrasing ("method", "which was") and short sentences, without the aggregating structure ("over three-quarters") that ties the top three methods together in the higher bands.

The pie chart shows the different methods that were used to manage municipal solid waste in the city of Da Nang, Vietnam, in 2024, given as percentages.

Overall, landfill was clearly the most common method of managing the city's waste, while chemical and hazardous treatment was the least common method. Recycling was also an important part of the waste management system.

Landfill was used for the largest share of waste, at 42%. Recycling was the second most common method, used for 24% of waste, and incineration was used for a further 15%. Together, these three methods accounted for most of the total waste produced in the city.

The other three methods played a much smaller role. Composting made up 11% of the waste, which was more than exporting for recycling abroad (5%) and chemical and hazardous treatment, which was the smallest method of all at only 3%.

Examiner Notes

  • TROverall, landfill was clearly the most common method of managing the city's waste, while chemical and hazardous treatment was the least common method.Identifies the highest and lowest categories like the 7.5 answer, but with repeated wording ("method... method") instead of varied vocabulary.
  • LRTogether, these three methods accounted for most of the total waste produced in the city.A safe, correct summarising phrase, but far less precise than the 7.5 answer's "responsible for over three-quarters".
  • GRAComposting made up 11% of the waste, which was more than exporting for recycling abroad (5%) and chemical and hazardous treatment, which was the smallest method of all at only 3%.Two "which" relative clauses are strung together correctly but repetitively, rather than the varied comparative-plus-relative structure of the 7.5 answer.
  • CCThe other three methods played a much smaller role.A functional pivot sentence, but shorter and less elaborated than the 7.5 answer's "By contrast, the remaining methods played a considerably smaller role."
Band 7.0

This 7.0 answer adds the aggregating "more than three-quarters" comparison and a denser final sentence, but its transitions and vocabulary choices are still slightly less economical and varied than the 7.5 answer's.

The pie chart illustrates the various methods employed to manage municipal solid waste in the city of Da Nang, Vietnam, during 2024, with each method shown as a percentage of the total amount processed.

Landfill disposal accounted for the largest proportion of waste, at 42%. Recycling was the next most common method, handling 24% of the total, followed by incineration at 15%. Together, these three methods were responsible for more than three-quarters of all waste processed in the city.

The remaining three methods, however, played a considerably smaller part in the overall system. Composting accounted for 11% of waste, somewhat more than exporting for recycling abroad, which made up 5%, and chemical and hazardous treatment, the least common method overall at just 3%.

Examiner Notes

  • TROverall, landfill disposal was by far the most widely used method of handling the city's waste, whereas chemical and hazardous treatment made up the smallest proportion.Names the highest and lowest categories in one balanced sentence, matching the 7.5 answer's overview strategy closely.
  • LRthese three methods were responsible for more than three-quarters of all waste processed in the cityAggregates several figures with a natural summarising phrase, close to the 7.5 answer's "Combined... responsible for" but slightly less economically phrased.
  • GRAComposting accounted for 11% of waste, somewhat more than exporting for recycling abroad, which made up 5%, and chemical and hazardous treatment, the least common method overall at just 3%.Strings a comparative clause and an appositive together to cover three figures in one sentence — ambitious, though slightly less tightly controlled than the 7.5 answer's version.
  • CCThe remaining three methods, however, played a considerably smaller part in the overall system.A clear pivot sentence separating major from minor methods, functionally equivalent to the 7.5 answer's transition but with a slightly less economical "however" insertion.
Band 7.5

The 7.5 answer stands out for its balanced overview sentence naming both extremes, the natural aggregating phrase "Combined... responsible for", and a comparative-plus-relative-clause sentence that links three figures fluently in one breath.

The pie chart illustrates the different methods employed to manage municipal solid waste in the city of Da Nang, Vietnam, in 2024, presented as percentages of the total waste processed.

  • LRCombined, these three methods were responsible for over three-quarters of all waste management activities in the city.The summarising phrase "Combined... responsible for" is a natural way to aggregate several figures without simply adding numbers mechanically.
  • GRAComposting was used for 11% of the waste, a figure noticeably higher than exporting for recycling abroad, which accounted for 5%A comparative structure ("noticeably higher than") combined with a relative clause links three data points inside one sentence.
