The diagram illustrates the process by which people throw away waste, which is then collected, recycled at a factory, and transformed into new products.

Overall, this process is a cyclical process. At the beginning, people throw away the trash. At the end, garbage is modified into new useful products.

Firstly, people dispose of the trash, then the trash truck takes the garbage and transports it to a factory where it is collected and recycled, while a person sorts the rubbish into types like suitable or not. The next step is collecting the garbage to compress it into blocks, then the valid trash is crushed and washed.

At the end of the process, the clean and suitable waste is altered to produce plastic pellets through techniques; then, the plastic pellets are heated to form raw material. The factory uses the raw materials to create eco-friendly and suitable products for people, and there are two types: first is clothes, and second is eco-friendly plastics that are no longer harmful to the environment.

Task Response

The report covers all the main stages of the recycling process and provides a clear overview. The structure is logical, moving from the initial collection to the final production of goods. To improve, ensure that the sequence of steps is more precise; for example, the report suggests the trash is compressed into blocks before being crushed, whereas the visual description indicates crushing occurs before compression. Additionally, using a wider range of cohesive devices and more varied vocabulary for the stages of transformation would enhance the overall flow and sophistication of the report.

Coherence & Cohesion

The report follows a logical progression, but the cohesion could be improved. While you use transition words like 'Firstly', 'The next step', and 'At the end', the flow between sentences can feel somewhat repetitive or mechanical. To improve, try using more varied cohesive devices, such as relative clauses (e.g., '...to a factory, where it is...') or participial phrases (e.g., 'After being sorted, the plastic is...') to connect ideas more smoothly rather than relying on a simple 'Step A, then Step B' structure.

Lexical Resource

The vocabulary is adequate for describing the process, but it lacks the sophistication required for higher bands. There is a heavy reliance on general terms like 'trash', 'garbage', and 'suitable'. To improve, use more specific terminology related to the diagram, such as 'waste materials', 'sorted', 'processed', 'raw material', or 'manufactured goods'. Additionally, avoid repetitive phrasing; for instance, instead of saying 'people throw away the trash' multiple times, you could use 'disposal of waste' or 'discarding plastic bottles'.

Grammatical Range & Accuracy

The report demonstrates a mix of simple and complex sentence structures, but there are issues with precision and phrasing. Some sentences are slightly awkward, such as 'the valid trash is crushed', where 'valid' is not the most appropriate word for waste material. There is also a tendency to use very simple sentence structures. To reach a higher band, focus on using a wider range of passive voice constructions, which are essential for describing processes (e.g., 'The bottles are collected' instead of 'the truck takes the garbage'), as this sounds more professional and objective in academic writing.
