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 illustration gives information about the recycling process of plastic bottles and how new products are formed. Overall, recycling process invovle nine steps and heating is involved to produce raw material which is basic source for producing new products.

It is quite evident from the diagram someone is throwing plastic bottle into a dustbin. Then, with the help of a truck this waste is transferred into recycling centre, where sorting si done. After all these ara arranged then, these bottles are compressed into blocks. After that crushing start, with the help of crushing machine these blocks are crushed and crushed parts fall into water tank where washing is done. However, the plastic pellets are produced with the aid of pellet machine. Then heating is done to produce raw material from these pellet. Thus, raw material is the basic source of producing new end products like T-shirts, plastic bags and lead pencil. The importent point is that all steps should occur in sequence, if one step is messed up end product should not be recieved.

Task Achievement / Task Response: Band 6.0

You cover the main sequence from putting bottles in a bin through collection, sorting, processing and making new products. The overview also identifies the nine steps and the role of heating in producing raw material, which gives the reader a useful summary. However, some details are less fully or accurately reported: the sorting stage separates acceptable bottles from rejected items, and the final products include food containers as well as clothing, pencils and bags. The statement that every step must occur in sequence or the end product will not be received is an unsupported conclusion rather than information shown in the diagram. Focus on describing the illustrated stages and make the overview capture the closed-loop nature of the process.

Coherence and Cohesion: Band 6.5

The response has a clear overall progression, and sequencing phrases such as “Then,” “After that” and “Thus” help guide the reader through the stages. The opening overview is also separated from the process description, giving the account a basic structure. This organisation is generally coherent, though the long process paragraph makes several stages feel crowded together. Some links are mechanical or unclear, particularly “After all these are arranged then,” and “However” does not express a contrast between pellet production and the preceding stage. The final comment about steps being messed up interrupts the process sequence. Use clearer paragraphing and choose linking words according to the relationship between ideas to make the progression more controlled.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “recycling centre,” “compressed,” “crushing,” “pellets” and “raw material,” so the stages are usually identifiable. There is also some attempt to vary wording through phrases such as “with the help of” and “with the aid of.” However, several word choices and collocations are awkward or imprecise, including “dustbin” for a recycling bin, “basic source” for the material used to make products, and “lead pencil” where “pencil” is sufficient. Spelling errors such as “invovle,” “importent” and “recieved” are noticeable. Build accuracy by learning common process collocations and checking spelling and word forms before finishing.

Grammatical Range and Accuracy: Band 5.5

You attempt a mix of simple and complex sentences, including a relative clause in “where sorting is done” and a conditional sentence at the end. Most of the process remains understandable, but some grammatical errors recur. For example, “recycling process involve nine steps” needs an article and subject–verb agreement, while “these pellet” needs a plural form. The construction “After all these are arranged then” is incomplete or awkward, and “After that crushing start” has an incorrect verb form. There is also an unnecessary repeated verb in “are crushed and crushed parts fall.” Practise checking articles, agreement, plurals and verb forms, and simplify sentences when a longer construction becomes difficult to control.
