Model Answer 1 (Band 9)

The given process diagram outlines the process of recycling plastic bottles, and it comprises a total of nine distinct steps. The recycling process commences with the first step, wherein the plastic bottles are discarded into the trash by the users. After that, the garbage trucks collect these bins of waste and transport them to the recycling centre. In the third step, the plastic bottles are sorted manually into two categories, one that is recyclable and the other that is not.


The subsequent three stages focus on the preparation of the recyclable plastic bottles. In step four, the compressing of plastic bottles is done to minimize the volume of waste. In step five, these compressed blocks are then crushed using a grinder and transferred to a washing tank. Finally, the washed plastic pellets are produced by passing the material through a machine in step six.


The remaining three stages highlight the manufacturing process. Step seven depicts how these plastic pellets are heated and turned into raw materials suitable for making plastic products. In step eight, the raw materials are placed on pallets for storage, awaiting the manufacture of plastic products. In the final step, finished plastic products are produced from these raw materials. However, after using these products, they might again end up being thrown into the trash and be recycled back into the system.

Model Answer 2 (Band 8.5)

The diagram illustrates the process of plastic bottle recycling, which is a circular process involving three primary stages that include collection and sorting, processing and cleaning, and reconstitution into a novel material for further usage.


The process begins with individuals placing plastic bottles into designated recycling bins that are loaded into specialized garbage trucks for transportation to the recycling centre. At the centre, the bottles are sorted by hand, compressed into blocks, and then crushed into small pieces before being washed.


The next stages of the process focus on transformation into reusable material. The pieces of plastic are poured into a machine that turns them into pellets, which are then heated to create a raw material that can be used to manufacture various products such as clothes, bottles, containers, and pencils. These products are themselves recyclable, and the process begins anew. In this way, plastic bottles can be continuously recycled, reducing the amount of plastic waste in the environment and conserving natural resources.

Model Answer 3 (Band 8)

The diagram depicts the recycling process of plastic bottles, which is a cyclical process that includes multiple stages. The process commences with the use of plastic bottles, followed by collection, sorting, crushing, cleaning, pelletizing, making new plastic products, and ultimately reuse.


Initially, the used plastic bottles are discarded into recycling bins and subsequently transported to recycling plants using trucks. Once at the recycling plant, the plastic bottles are sorted and segregated into those that can be recycled and those that cannot. The recyclable bottles are then compressed into blocks for ease of processing.


The next phase of the recycling process focuses on processing the recyclable plastic. In this phase, the compressed plastic blocks are broken down into smaller pieces by a crushing machine, which are then cleaned to remove any impurities. The clean plastic pieces are then fed into a machine that transforms them into small plastic pellets, which are melted and turned into raw material.


Finally, the raw plastic material is used to manufacture a wide range of plastic products, such as bottles, pens, and reusable shopping bags. Once these products have been used and discarded, the recycling process begins anew, creating a closed-loop cycle of plastic production and recycling.



Model Answer 4 (Band 8)

The diagram provides a detailed overview of the recycling process of plastic bottles, which involves a sequence of steps starting from disposal and concluding with the production of finished products.


Initially, plastic bottles are collected in designated bins, and then transported to recycling centres by garbage trucks. Once there, the bottles are separated into useful and non-useful categories by workers, in a process known as sorting. The subsequent steps involve the compression of the sorted bottles into blocks, which are then crushed and washed to remove impurities. After cleaning, the crushed plastic is fed into a machine that converts it into pellets. The pellets are then heated, resulting in the formation of raw material that can be utilized in the manufacture of various end products.


In the final stage, the recycled raw material is used to create a range of plastic products such as pens, bottles, and reusable bags. These products are designed to be durable and sustainable, allowing them to be reused and recycled again Overall, the recycling process for plastic bottles is a comprehensive procedure that starts with the collection of used bottles and concludes with the production of new products.



Model Answer 5 (Band 7)

The circular diagram illustrates the step-by-step process of recycling plastic bottles. In essence, the recycling process can be divided into nine stages - starting from collection and sorting of bottles, moving through the processing and cleaning, and ending with the production of new plastic-made goods that can be recycled again.


To commence, plastic bottles are placed in designated recycling bins by individuals. These bins are then collected and transported to recycling centres by garbage trucks. At the recycling centres, workers sort the recyclable bottles from the non-recyclable ones. The selected bottles are then compressed and converted into blocks, which are later passed through crushing machines. This process results in small pieces of plastic that are washed and then fed into a machine that turns them into plastic pellets.


The next step in the process involves heating the plastic pellets to create raw materials suitable for producing a variety of plastic-made consumer goods. The raw materials are then refined and rolled and used in the production of various items, such as plastic bottles, containers, t-shirts, pens, and more. The process comes full circle when the end products are placed in designated recycling bins to be recycled again. This circular process allows the recycling of plastic bottles to continue, reducing the negative environmental impact of plastic waste.
