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 5.5)

The illustration gives information about the recycling of plastic bottles and formation of new end products. Overall, the recycling process involve nine steps in which heat is involved to produce raw material which one the basic source of producing new materials.

It is quite evident from the diagram someone is throwing plastic blottles into dustbean. Then, with the help of this waste disposal transfer to the recycling centre where sorting done. However, after all arrangements these are compressing into blocks after that crushing of these block done with the help of crushing machine. Crushed parts fall in water tank where wasing is done for these parts.

Furthermore, pellets machine is used to produce the plastic pellets of of desired size, heat these pellets to produce raw material. However, these material are source of producing new products like that T shirts, plastic bag and lead pencil. One thing is more importent that all these steps should occur in sequence if one steps is messed end product should not recieve.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

You cover the main stages from bottle disposal through collection, sorting, compression, crushing, washing and pellet production to new products, and your opening overview identifies the nine-step process and the production of raw material. These details are broadly consistent with the diagram. However, some important features are less fully or clearly reported: the sorting stage separates acceptable bottles from rejected items, and the final products are made from the raw material before the cycle returns to the recycling bin. The claim that “if one steps is messed end product should not recieve” is not shown by the diagram and introduces an unsupported condition. A clearer overview of the complete cycle and more precise coverage of its final stages would make the summary more complete.

Coherence and Cohesion: Band 6.0

The response has a generally coherent sequence, with paragraphs moving from disposal and sorting to processing and end products. Connectors such as “Then” and “Furthermore” help signal progression, and the reader can follow the broad process. However, some linking is mechanical or unclear: “However” does not express a contrast in either of its uses, and “after all arrangements” does not clearly identify the preceding stage. References such as “these” and “these material” also make it harder to tell exactly which items are meant. Organise the stages with clearer time or process links, and use explicit nouns when moving between bottles, crushed pieces, pellets and raw material.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “sorting,” “compressing,” “crushing,” “pellets” and “raw material,” which helps communicate the diagram’s main stages. However, the range and control are uneven, with noticeable spelling and word-choice problems such as “blottles,” “dustbean,” “wasing” and “importent.” Some phrases are also unnatural or imprecise: “waste disposal transfer” and “pellets machine” do not describe the process clearly, while “lead pencil” is not the usual term for the pictured product. Choose standard process collocations and check spelling carefully. More precise vocabulary for the sorting and manufacturing stages would make the account easier to understand.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentence forms, including the opening overview and the sequence introduced by “after that.” The overall meaning is usually recoverable, but some grammatical errors affect clarity. For example, “the recycling process involve” has subject–verb disagreement, and “where sorting done” is missing an auxiliary verb. In “these are compressing into blocks,” the passive form is incorrect; the process should be described with a correctly formed passive. There are also problems with articles, plurals and sentence boundaries, as in “these material are source.” Practise accurate passive constructions for process descriptions and check agreement and complete verb phrases when revising.
