- Overall: This circular process is comprised of 3 main stages including initial collection and sorting, followed by processing and cleaning, and finally reconstitution into a novel material for further usage (IELTS TUTOR gợi ý cách diễn đạt khác: the process involves nine steps, starting from the collection of bottles for recycling to the manufacturing of new plastic products) >> IELTS TUTOR hướng dẫn Cách dùng động từ "involve"
- Body 1:
- Recycling commences when an individual places their rubbish in a designated recycling bin, prior to being loaded into specialized garbage trucks (IELTS TUTOR gợi ý cách diễn đạt khác: In the first step, used plastic bottles are collected in trash bins placed in different locations. Once these bins are full, they are transferred to the recycling centre via trucks)
- After transportation to the recycling center, the plastic bottles are sorted by hand, compressed tightly to form blocks and then crushed into small pieces and washed. (IELTS TUTOR gợi ý cách diễn đạt khác: At the recycling centre, the collected bottles are segregated manually. Bottles which can be recycled are sent to the compressing unit, whereas those cannot be recycled are disposed)
- Body 2: The next stages involve transformation into a reusable material.
- The pieces of plastic are first poured into a machine that turns them into pellets.
- These pellets are then heated in order to create a raw material that can be used in the manufacture of products ranging from clothes and bottles to containers and pencils (IELTS TUTOR gợi ý cách diễn đạt khác: In the next step, these pellets are heated to make the raw materials for the manufacturing of finished plastic goods like containers, bottles, tee-shirts and carry-bags)
- These items are themselves recyclable and the process begins again. >> IELTS TUTOR hướng dẫn Cách dùng danh từ "item" tiếng anh

The diagram illustrates the step-by-step (adj: tuần tự, từng bước – sequential, gradual, progressive – abrupt, sudden, hasty) process of recycling plastic bottles.
Overall, this cyclical (adj: tuần hoàn – repetitive, recurring, circular – linear, one-way, finite) system consists of nine stages, beginning with the household collection (n: thu gom tại hộ gia đình – domestic gathering, residential collection, home-based collection – industrial collection, factory retrieval, commercial gathering) of discarded bottles and culminating in the creation of new plastic items.>> Form đăng kí giải đề thi thật IELTS 4 kĩ năng kèm bài giải bộ đề 100 đề PART 2 IELTS SPEAKING quý đang thi (update hàng tuần) từ IELTS TUTOR
In the initial phase, used bottles are disposed of in designated bins (n: thùng được chỉ định – assigned containers, marked bins, allocated receptacles – random bins, unmarked containers, unrestricted bins) and subsequently transported by specialized trucks to a recycling facility. There, workers manually sort them, after which recyclable bottles are compressed into compact blocks, crushed into smaller fragments, and thoroughly washed.
Following this, the fragments are processed into pellets through mechanical conversion. These pellets are then subjected to heating, producing a versatile raw material (n: nguyên liệu đa dụng – flexible base, adaptable substance, multi-purpose material – limited material, inflexible base, restricted resource). This is subsequently employed in the mass production of goods such as clothes, containers, bottles, and stationery. Crucially, these newly manufactured products are themselves recyclable, allowing the cycle to recommence.
