Cambridge 16 Writing Task 1 Test 4 - Sample Answers (Band 9 to 4-5)

The diagram illustrates the process by which used plastic bottles are recycled and transformed into new products, comprising seven sequential stages.

Overall, the process moves bottles from unsorted household waste through a series of mechanical and thermal treatments until they are converted into raw material suitable for manufacturing entirely new items, with no stage in the sequence being repeated or reversed.

The process begins with the collection of used plastic bottles from households and dedicated recycling points. These bottles are then delivered to a recycling centre, where they undergo sorting by type and colour, before being compressed into large bales in order to save storage and transport space.

Following compression, the bales are broken down and the bottles within them are crushed into small flakes. These flakes are then thoroughly washed to remove any remaining labels, dirt, or contaminants, before being melted and formed into small pellets, which serve as the raw material for new products. In the final stage, these pellets are used to manufacture entirely new items, such as clothing, furniture, and new bottles, completing the transformation from discarded waste into usable material.

The diagram shows how used plastic bottles are recycled, involving seven stages in total.

Overall, the process takes bottles from household waste through several mechanical steps and turns them into raw material that is used to make new products, with each stage happening only once.

First, used bottles are collected from households and recycling points, then taken to a recycling centre where they are sorted by type and colour. After sorting, the bottles are compressed into large bales to save space.

The bales are then broken down and crushed into small flakes, which are washed thoroughly to remove labels and dirt. These clean flakes are then melted and formed into pellets, the raw material for new products. Finally, these pellets are used to make new items such as clothing, furniture, and bottles. No stage in this process is skipped or repeated, and each step depends on the material having been correctly processed in the stage before it.

The diagram shows the process of recycling plastic bottles. There are seven steps in total.

Overall, the bottles go through several stages and are turned into new products at the end.

First, bottles are collected from homes and recycling points. They are then sorted by type and colour at a recycling centre, and after that, they are compressed into bales.

The bales are crushed into small pieces, which are washed to remove dirt. Then they are heated and made into pellets, which are used to make new products like clothes and furniture. Each of these seven steps happens in a fixed sequence, and no stage is ever repeated or skipped, meaning the whole process turns discarded bottles into completely new, usable products from start to finish. This kind of closed-loop recycling reduces the need for manufacturers to produce new plastic from raw petroleum, which is both more expensive and more damaging to the environment than reusing material that has already been through the system once.
