How plastic bottles are recycled

Student answer (Band 6.0)

The provided diagram illustrates the multistage process of recycling bottles to produce new products

Overall,the process consists of nine major steps,beginning with the disposal of used plastic bottles and culminating in the creation of various recycled end products.

The process starts when a consumer disposes of a plastic bottle in a recycle bin.Then truck comes and take the bottles into recycle factory and then put them in a machine,after sorting them in the recycle center.Then,the machine crushes the material and then the bottled will be washed off.After washing , the fragments of plastic will be add into another machine. Consequently,the fragments become heated.After heating the fragments,the fragments come in a position where they can be converted into raw material.However, the raw material will be use to produce a large variety of things such as books,cloths,stationary,bags and utensils for the house.Then they can be sent into some shops for further selling in cheap rates.

Task Achievement / Task Response: Band 6.0

You identify the process as a sequence from disposing of bottles to making new products, and your overview correctly notes its nine stages and broad starting and ending points. The main stages are generally represented, including collection, sorting, crushing, washing, heating and conversion into raw material. However, some details are inaccurate or unsupported: the diagram shows plastic pellets being produced before they are heated, and the end products include containers, a T-shirt, pencils and a carrier bag—not books, clothing, stationery and household utensils as stated. The claim that products are sold cheaply is also not shown. To strengthen the response, report the pellet-making stage and the return arrow that completes the cycle, and keep examples closely tied to the diagram.

Coherence and Cohesion: Band 6.0

The response has a recognisable overall structure: an introduction, an overview and a chronological account of the process. This makes the main progression understandable. However, the body is presented as one long paragraph, and repeated links such as “Then,” “After washing” and “After heating” make the sequence sound mechanical. Some references are also unclear, particularly “the fragments come in a position where they can be converted,” which does not clearly connect the heating stage to the raw material. Use separate paragraphs for the overview and process details, and group stages into clearer phases. More precise transitions and references would help the reader follow the cycle, including its return from end products to the recycling bin.

Lexical Resource: Band 6.0

You use an adequate range of process vocabulary, including “disposes,” “sorting,” “fragments,” “heated” and “raw material,” so the stages are mostly understandable. There are also attempts at more specific terms, such as “recycle factory” and “end products,” although some choices are inaccurate or unnatural. For example, “recycle factory” is better expressed as “recycling centre,” while “sent into some shops for further selling in cheap rates” is both unsupported by the diagram and awkwardly phrased. “Books,” “cloths” and “stationary” do not accurately name the pictured products. Aim for precise labels from the visual and natural collocations, such as “plastic pellets are produced” and “a range of products.”

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more complex sentences, including a sequence of clauses linked with “when,” “after” and “consequently.” The overall meaning can usually be followed, but some grammatical errors recur. For example, “truck comes and take” has article and agreement problems, while “the fragments of plastic will be add” and “the raw material will be use” use incorrect passive verb forms. There are also errors in sentence boundaries and punctuation, such as missing spaces after full stops and commas. Practise forming passive constructions accurately (“are added,” “is used”) and check subject–verb agreement and articles. Shorter, carefully punctuated sentences would improve control while you continue to use a range of structures.
