IELTS Writing Task 1 question

The diagram below shows the process for recycling plastic bottles.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

How plastic bottles are recycled

Student answer (Band 6.0)

The diagram shows the procedure for the reuse of polythene-base products after being recycled.

Overall. The process contain three main stages from throwing to reproducing it. In the first stage from throwing to sorting Then followed by compressing to producing plastic beads and on the last stage how it return back to consumers.

In the beginning consumer threw plastic base products in nearby garbage bins, Government operated truck came and collect it. After It goes to the factory where it is shorted by hand and plastic that can recycle put aside. On the second stage, all the sorted plastic bottles where compressed into a giant square block which later pass throw two giant crusher and converted into a small pieces and then goes to a water tank for washing. Now these clean pieces are send to machine to convert it into micro size and leaving it on heating pallet to form raw material.

in the last stage, when the raw material is ready it kept it on wooden pallet as a large chunk of plastic which can be converted into daily use products such as bottles, food containers, T-shirts, plastic bags and Pencils. Which eventually comes back to consumers.

Task Achievement / Task Response: Band 6.5

You cover the main stages and give a clear overall account of the cycle, from disposal and collection through processing to the production of consumer goods. The overview identifies the broad progression, and the examples of end products—bottles, food containers, T-shirts and bags—match the diagram. Several details are also reported accurately, including sorting, compressing, crushing and washing. Some points are less fully or precisely described: the diagram shows recyclable bottles being separated from rejected items, while “plastic that can recycle put aside” is unclear; it also shows pellets being heated to form raw material, rather than “heating pallet.” The return arrow to consumers is a reasonable summary of the loop, but the overview could explain the recycling cycle more precisely.

Coherence and Cohesion: Band 6.5

The response has a recognisable structure: an introduction, an overview and two paragraphs describing the stages. The sequence is generally easy to follow, with markers such as “In the beginning,” “On the second stage” and “in the last stage” helping the reader track the process. This gives the account a coherent overall arrangement. However, some linking is mechanical or unclear, and the overview’s sentence beginning “In the first stage…” runs into “Then followed by…” without a clear grammatical connection. The final paragraph also begins with a lower-case “in,” and the sentence starting “Which eventually…” is detached from the preceding idea. Use fewer stage labels and connect related steps in complete sentences to make progression smoother.

Lexical Resource: Band 5.5

You use a reasonable range of process vocabulary, including “compressed,” “crusher,” “washing,” “raw material” and “converted,” and the reader can usually understand the stages. There are also attempts at more specific wording, such as “giant square block” and “micro size.” However, several inaccurate or awkward choices reduce precision: “polythene-base products” does not accurately describe the bottles, “shorted” appears to mean “sorted,” and “heating pallet” confuses pellets with a pallet. “Garbage bins” and “Government operated truck” are less suitable or unsupported descriptions for this diagram. Aim for accurate process terms and natural collocations, especially when naming materials and machinery.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more extended sentences, including a sequence joined with “which later…” and a final clause describing products returning to consumers. However, control is uneven, and errors in verb forms, agreement, articles and sentence boundaries sometimes make the process difficult to follow. For example, “The process contain” should be “The process contains,” while “consumer threw” and “truck came and collect” do not maintain appropriate tense and agreement. In “when the raw material is ready it kept it,” the passive construction is incomplete, and “Which eventually comes back…” is a sentence fragment. Several sentences also need clearer punctuation. Practise accurate past-tense passive forms and check that each sentence has a complete main clause.
