How plastic bottles are recycled
Student answer (Band 6.0)
The cyclic diagram illustrates the method of recycling plastic bottles.
Overall, it is evident that the process of reuse of plastic bottles is a cyclic process which consists of 9 substantial steps. It starts from throwing of garbege into dustbins, followed by several steps, ends with the formation of products such as tea shirts, plastic bottles, boxes and bags. which then put again into dustbins and the process starts agains.
The recycling process of plastic bottles starts when residents through waste products in trash, it is transfered to recycling centre called sorting through trucks. In sorting, the garbage is seperated then it is compressed into blocks, before passing blocks into crusher.The crusher breaks blocks into small particles which then washed in water.
Subsequently, the cleaned particles are put into a machine where plastic pellets are formed. Furtherafter, the pellets are heated at high temperature to form raw material which is arranged in blocks. Finally, some renewable products are formed from raw material such as shirts, bottles, boxes and shopping bags. All these products individuals use in their daily life after using it they through these products in dustbins as a waste product and the cycle repeats again.

Task Achievement / Task Response: Band 7.0
The response successfully addresses all parts of the task by providing a clear overview and outlining the main features of the cyclic plastic bottle recycling process. The stages are reported in a logical sequence, starting from throwing garbage into bins through sorting, crushing, washing, pelletising, and manufacturing, back to the consumer stage. While the overview captures the main trend well, some details are slightly generalized, which is characteristic of this band. The mechanical nature of the process is adequately captured, showing a clear understanding of the visual information provided in the prompt.
Coherence and Cohesion: Band 6.5
The response demonstrates a clear overall arrangement with a logical progression from the beginning to the end of the recycling loop. Paragraphing is utilized, separating the introduction and overview from the detailed body steps. Cohesive devices are employed to connect the stages, using transitions such as 'Subsequently', 'Furtherafter', and 'Finally'. However, some referencing is slightly faulty or mechanical, and certain sentences run together or lack smooth integration, preventing the response from reaching a higher level of cohesion. Overall, the flow is sufficiently clear for the reader to follow the cyclical nature of the diagram.
Lexical Resource: Band 5.5
The vocabulary used is adequate for the task, attempting some less common items related to the recycling process such as 'cyclic', 'compressed', 'crusher', and 'pellets'. However, there are noticeable lexical errors, spelling mistakes, and awkward word choices throughout the text, such as 'garbege', 'tea shirts', 'agains', 'through' instead of 'throw', and 'Furtherafter'. These inaccuracies indicate a limited control over word formation and spelling, which keeps the lexical score constrained, although communication is generally maintained despite these errors.
Grammatical Range and Accuracy: Band 5.0
The writer attempts a mix of simple and complex sentence forms to describe the process. However, there are frequent grammatical errors involving verb forms, tenses, subject-verb agreement, and missing prepositions or articles, such as 'products such as tea shirts... which then put again', 'residents through waste products', and 'after using it they through these products'. These frequent errors in basic and complex structures cause some difficulty for the reader and reflect typical patterns of a limited structural range and control.
