The diagram details the process of making clothes from plastic bottles.
Sample Response
The picture illustrates the process in which plastic bottles are transformed into clothes.
Overall, it is apparent that there are three main stages involved in this recycling process, including the collection and classification of plastic bottles, the preparation for plastic pieces and the production of clothes.
At the beginning, used plastic bottles of different sizes are gathered before being loaded onto trucks and transported to the factory. There, as soon as the bottles are sorted out, they are shredded into minuscule pieces. These pieces are then washed and left in the sun to dry for 10 hours.
Following this, once the plastic pieces are dry, they are put in a boiling machine, after which the water is strained off, resulting in melted plastic. At this point, the melted plastic is spun into flexible yarn which is later woven into fabric. The final stage is when the fabric is neatly rolled up and ready to be made into garments.
IELTS Writing Correction
- 1. Use the stage label Original: classification Suggested revision: sorting Why it matters: Sorting is the process stage explicitly shown in the diagram.
- 2. Correct the preposition Original: preparation for plastic pieces Suggested revision: preparation of the plastic pieces Why it matters: Preparation of correctly describes the treatment of the pieces themselves.
- 3. Remove unsupported detail Original: used plastic bottles of different sizes Suggested revision: plastic bottles Why it matters: The diagram does not specify that the bottles differ in size or explicitly label them as used.
- 4. Match the diagram Original: transported to the factory Suggested revision: transported to factories Why it matters: The visual labels this destination as factories in the plural.
- 5. Remove invented duration Original: left in the sun to dry for 10 hours Suggested revision: left in the sun to dry Why it matters: The diagram shows sun-drying but provides no ten-hour duration.
- 6. Avoid invented stages Original: the melted plastic is spun into flexible yarn Suggested revision: the strained plastic is made into yarn Why it matters: The diagram moves from straining to yarn without showing melting or a separate spinning stage.
- 7. Use a precise verb Original: is when Suggested revision: involves Why it matters: Involves creates a more direct and grammatically controlled description of the final stage.
- 8. Sentence rewrite Original: Following this, once the plastic pieces are dry, they are put in a boiling machine, after which the water is strained off, resulting in melted plastic. Suggested revision: Following this, the dry plastic pieces are boiled and then strained. Why it matters: The visual shows boiling followed by straining but does not show water being removed or label the material as melted plastic.

Why this response received Band 8.0
The response presents the full process in a clear chronological sequence, supported by a concise overview and flexible, largely accurate language. Its main limitation is the unsupported claim that drying takes 10 hours, a detail absent from the diagram, alongside a few slightly awkward phrases. Prioritise strict visual accuracy by avoiding invented durations and using the diagram's process labels precisely.
IELTS Writing Criteria Scores
Task Achievement
All major stages are covered in the correct order with a clear overview, but the stated ten-hour drying duration is unsupported by the diagram.
Report only information shown in the visual and remove any unlabelled duration or other inferred detail.
Coherence and Cohesion
The overview and stage descriptions are sequenced naturally, with cohesive devices guiding the reader smoothly through the process.
Keep the strong chronological structure while making the overview's three-stage grouping more precisely parallel.
Lexical Resource
A wide and precise process vocabulary is used effectively, including 'shredded', 'strained', 'spun', and 'woven', with only slight awkwardness.
Refine less natural combinations such as 'preparation for plastic pieces' to 'preparation of the plastic pieces'.
Grammatical Range and Accuracy
A broad range of complex passive and subordinate structures is used accurately and flexibly, with only minor imperfections.
Maintain this control while tightening occasional long sentences so each process relationship remains maximally precise.
