How plastic bottles are recycled

Student answer (Band 6.0)

The given chart depicts the process how the waste bottles are used to recycle through different stages.

Overall, the image describes all the steps that are carried out to recycle the usless bottles. The whole process contains nine stages and first stage starts with the dumping of garbage and last stage ends up with the producing the new commodities.

As the process begin with the dumping of garbage into the dustbin and then the trucks are used to carry the trash to recycling centre for the process of sorting. After that the useless bottles are used to compress into blocks. After that, the blocks are used to be crushed into thin material by two rollers.

As the process continues, the washed material is used to produce plastic pellets and heated to from raw material for new product. In the last stage raw material finally trun into final product for customer use.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

You identify the process as a nine-stage cycle and describe its broad progression from disposal and collection through sorting and processing to new products. This gives a relevant overview, and most of the stages you mention match the diagram. However, some details are unclear or inaccurate: bottles are put into a recycling bin, rather than simply “dumping of garbage,” and the sorting stage includes separating suitable bottles from rejected items. The account also skips the explicit washing stage and does not explain that the finished products feed back into the cycle. Develop these features and describe the final products more specifically to make the coverage of the process more complete.

Coherence and Cohesion: Band 6.0

The response has a recognisable structure: an introduction and overview are followed by two paragraphs describing the stages in sequence. The reader can generally follow the process from collection to the production of end goods. However, cohesion is sometimes mechanical, particularly through repeated use of “After that” and “As the process,” and the final paragraph compresses several stages into one sentence. Some references are also unclear, such as “the useless bottles” and “the washed material,” because the sorting and washing steps have not been fully explained. Use a wider range of sequencing language and give each major phase clearer links so the progression feels smoother.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “recycling centre,” “sorting,” “compress,” “crushed,” “plastic pellets,” and “raw material,” which helps communicate the main stages. However, several choices are imprecise or unnatural for this diagram: “dumping of garbage” does not accurately describe placing bottles in a recycling bin, and “thin material” is not a clear description of crushed plastic. There are also spelling errors such as “usless,” “trun,” and “from” where “form” is intended. Aim for precise process terms and check spelling carefully; this will make the description more natural and exact.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple sentences and longer clauses, and the sequence is usually understandable. Some grammatical errors remain, however. For example, “The given chart depicts the process how” needs a construction such as “the process by which”; “As the process begin” has incorrect subject–verb agreement; and “the blocks are used to be crushed” is an awkward passive structure. The overview also has a faulty parallel construction in “first stage starts … and last stage ends up with the producing.” Practise accurate passive forms for process descriptions and check articles, verb agreement, and clause structure. These corrections would improve control while preserving your clear chronological account.
