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 demonstrates the procedure of recycling platic bottles.

Overall, this process have nine different stages from getting the plastic bottle manually to making new products from them.

Initally, the used plastic materials bought from the garbage boxes manully by workers. Moreover, the gathered material is transported to factory by using the transport vehicles such as trucks. In the recycling centre, a person is sorting the plastic things and the other material. Inthe forth stage, the seperated plastic material compressed and made into the blocks. Additionally, the blocks cruched by the crushing machine and make the little elements.

The crushed compounds washed into the washing tub. Then, in the sixth stage, the washed compoud produce the plastice pellets. The produced pellets are heated and make a raw material. The raw material is packed. and the raw material which is packed used to make the end products such as plastice bottles, storage boxes, t-shirts, pencils and the holding bags.

Task Achievement / Task Response: Band 6.5

You cover the main sequence from collection through sorting, processing and the production of new goods, and your overview correctly identifies a nine-stage process. The examples of final products—bottles, containers, T-shirts, pencils and bags—also match the diagram. This gives the report a clear, relevant account of the process. Some details are less fully or precisely reported: the sorting stage includes separating acceptable bottles from rejected material, but this distinction is not explained, and the account does not clearly state that the process loops back to the recycling bin. To strengthen the overview and coverage, highlight this circular nature and describe the key transformations more precisely, including crushing, washing, pellet production and heating into raw material.

Coherence and Cohesion: Band 6.5

The response follows the process in a generally logical order, and sequencing expressions such as “Moreover,” “In the fourth stage,” and “Then” help the reader track the stages. The opening overview is also separated from the process description, giving the report a basic paragraph structure. However, the body is presented as one long paragraph, and some links feel mechanical or unclear. For example, “Additionally” introduces the crushing stage without showing its relationship to compression, while “The raw material is packed. and the raw material…” creates an abrupt break and repeats the same idea. Use clearer paragraphing and connect each stage directly to the next; a final sentence noting the return to the start would make the progression feel complete.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “transported,” “compressed,” “crushing machine,” “pellets,” and “raw material,” which helps communicate the stages. However, the range is limited and several word-choice, collocation and spelling errors reduce precision: “bought from the garbage boxes” does not describe bottles being placed in recycling bins, and “little elements” is vague for the crushed plastic pieces. There are also repeated forms such as “material” and “raw material,” alongside misspellings including “platic,” “manully,” “seperated” and “compoud.” Aim for accurate, specific terms and check spelling carefully. For example, use “collected from recycling bins,” “plastic fragments,” and “reusable raw material” where appropriate.

Grammatical Range and Accuracy: Band 5.0

The report attempts both simple and more developed sentence forms, including a passive construction in “the gathered material is transported to factory” and a sequence of process clauses. However, control is inconsistent, and errors in verb forms, agreement, articles and sentence boundaries sometimes make the process harder to follow. Examples include “this process have nine,” “the used plastic materials bought,” and “the washed compoud produce”; these need forms such as “has,” “are collected,” and “produce/are used to produce,” depending on the intended meaning. The fragment-like break in “The raw material is packed. and…” also needs correction. Practise consistent passive forms for process descriptions and review articles and agreement, while keeping sentences complete and clearly punctuated.
