How plastic bottles are recycled

the diagram below shows the process for recycling plastic bottles

Sample Essay

The diagram illustrates how plastic bottles are recycled.

Overall, the recycling of plastic bottles is a cyclical process that consists of use, collection, sorting, crushing, cleaning, pelletizing, making new plastic products, and reuse.

After plastic bottles are used, they are discarded in recycling bins, waiting for trucks to transport them to a recycling plant. Once there, they are sorted and those that can be reused are compressed into blocks. The blocks are then broken down by a crushing machine into small pieces, which are subsequently cleaned to remove any residue.

The small clean pieces produced in the last stage are then poured into a machine where they are turned into pellets. The machine also heats and melts the pellets, which creates plastic raw material. Finally, the raw material is made into different plastic products, including pens, bottles, and reusable shopping bags. After these products are used, they go through the recycling process all over again.

How to Write the Overview

In your overview, if you say the recycling process is cyclical, you have to have a complete cycle that goes back to the start: use, collection, sorting, crushing, cleaning, pelletizing, making new plastic products, and reuse. The diagram hints at the step “use” by showing the user putting an empty bottle into the bin with no description. You have to mention “use” and “reuse”. Otherwise, you don’t have a complete cycle and you can’t say the process is cyclical.

  1. Hii, we should not write “consists of X steps, commencing from…, ending with… . ” in Overall of Only Cyclical process, right? But in other we can use it.

    1. Thanks for your question. It is better not to state only the first and last stages of a process whether it is a cyclical or linear one. Instead, we should summarize all the main stages. Please read the examiner’s comment on page 133 of Cambridge IELTS 16.

  2. The illustration displays the recycling process of bottles made of plastic.

    Overall, the plastic reusing process is cyclic and consists of five main stages: sorting at the center, compressing into blocks, crushing it, producing plastic pellets, heating it to get raw material that is then used to make plastic products and the cycle starts again.

    First of all, plastic garbage is transported into the recycling center by special truck that collects only plastic bottles. The plastic then separated into two sections where the ticked section is for plastics that are could be reused. After these sorted plastics are compressed into blocks and go to crushing. At the stage of crushing blocks are converted into tiny pieces and washed in full of the special liquid container. The chopping machine makes tiny pieces tinier making them look like powder. Plastic pellets are subsequently heated and melted to become more organized, dense, and more comfortable to use raw material. Plastic products could be manufactured by this raw material which starts the cycle again after discarding.

  3. The diagram illustrates the processes involved in re-manufacturing of used plastic bottles.

    Overall, the whole recycling procedure consists of 9 distinct stages. Beginning with collecting of used plastic bottles from the waste bin and ending with the final production of reusable plastic products.

    To begin with, truck load used bottles from the thrush bin and offload them to the recycling center for sorting out. From the there, those that are capable of remolding are selected and compressed into blocks, in addition, these blocks are sent to the crushing machine to be broken into finite particles. From this stage, the broken bottles are sent to the next stage for mailing where plastic pellets are produced.

    The other stage of the recycling procedure is heating of the pellets to form new raw materials which are subsequently turned into various plastic products such as pens, bags for shopping, drinking bottles, plastic bowls and other products.

    The diagram illustrates the procedure of how plastic bottles are recycled.
    overall, the entire recycling procedure consists of 9 stages. begins with collecting used plastic bottles from garbage bins and ends with output of recycled end products.

    To begin with,used plastic bottles are collected from garbage cans and then collected bottles are transferred to the recycling centres by vehicles. as the third step, bottles are sorted by employees who worked in recycling centres. next, sorted bottles are compressed into blocks and crushed with help of a machine.

    as the next step, Crushed pieces are washed in order to remove all the dirt. washed particles are entered to a machine and covert them into raw materials then converted raw materials are being melted and use to produce end products such as clothes, stationeries, bottles and so on.

  5. The diagram illustrates how plastic bottles get recycled.

    Recycling plastic bottles is a complicated, closed cycle process to convert used plastic bottles into new plastic goods. This process can be divided into two main stages. The first stage is producing plastic pellets and the second one is making new product from plastic pellets.
    To begin with, used plastic bottles must be put into recycle bins. From there, plastic bottles are collected and transported to a recycling center by recycle trucks. Inside recycling center, plastic bottles are sorted manually to seperate recyclable bottles from non-recyclable ones. Next, recyclable bottles are pressed into big cube-shape blocks, allowing them to better fit the crushing machine. In the crushing machine, blocks are ground up and shredded into flakes. Then, plastic flakes are submersed in a huge tank full of specially cleaning solution to eliminate bacteria and impurities. After that, plastic flakes are put into pelletizers to produce plastic pellets.
    In the second stage, plastics pellets are heated to form raw material. They are formed differently depending on the end products. In the end, raw materials are sent to warehouse and stay there until can be used in the manufature of the end products, such as clothing, nylon bags, plastic bottles and so on.

  6. Hello! Thank you a lot for all resourses. Could you please give me your feedback and maybe band?

    The diagram explains how plastic bottles are recycled. Some stages of the process and the equipment used are specified.

    It is clear from the diagram that, first, plastic bottles are thrown into trash cans. Second, it is picked by lorry and delivered to the recycling centre, where different types of waste are sorted by workers. Then plastic bottles are compressed into blocks. At the next stage they are crushed by a special machine and washed in the tank with water.

    Referring to the following steps, it can be noted that when it is over, plastic pieces are ground into plastic pellets. After that, they are heated, which is followed by forming raw material. Then it is completed and raw material is stacked. Finally, new products, such as containers, t-shirts, pencils, bags and bottles are produced. As the consumer reuse these items, it starts out the cycle of recycling again.

    Thus, there are nine steps in the process beginning with throwing plastic bottles.

  7. Hlo plz give me feedback on this overview

    The process consists of 9 steps beginning with collecting bottles and ends with new products. However, major phases includes collecting waste bottles, sorting,crushing and new materials production.

  8. The given diagram shows information on how used plastic bottles are recycled. In general, the illustration presents a continuous process with nine steps.
    At first, used bottles are deposited by the users in a movable big sized bin. Then, all the gathered bottles are collected by a covered truck for carrying towards recycling centre. In the centre, staffs sort recyclable bottles from unusable bottles and kept them in separate boxes.
    Later, selected bottles are compressed into different blocks. The blocks are placed in a two-wheeler crushing machine to be brocken into smaller pieces and these are washed in a large size water tank to remove wastages.
    The washed small plastic pieces, then, are poured in a cubic machine to produce plastic pellets. The pellets go through a heating process to form raw materials. The materials usually are kept in a storage and several plastic made products like bottles, food carrier, T-shirts, pens, bags, etc. are produced for everyday usages. After consuming, reused products are deposited again in the bin. The same recycling process is continued.

  9. The diagram illustrates how plastic bottles are recycled.
    Overall, there are 9 steps in this process cycle, starting from collection of used plastics to manufacturing new products from the recycled material.

    The process starts when consumers throw away used bottles in to the collection bins. These are then sent to a sorting centre by vehicles, where plastics that are suitable are manually selected. The selection is then compressed in to blocks, and the blocks are crushed in to small pieces.

    The end product from the last step is washed in tank to clean and these small pieces are processed in a machine which puts pellets of plastic. Heating of these pellets makes the raw material which then used to make various customer products such as bottles, boxes, etc. As the consumer reuse these items, it starts out the cycle of recycling again.

    1. Good essay. I think you may get a 7, but the overview can definitely be improved. Please read the examiner’s comment on Page 133 of Cambridge IELTS 16.

  10. The diagram illustrates how plastic bottles get recycled.

    Overall, the cycle comprises of nine processes that start by usage, collection, sorting, crushing, production of pellets, making new products, and ending up getting reused by people.

    After the usage of plastics, people get rid of them in special bins, and then recycling trucks transport them to a recycling center. In this center, the sorting process is accomplished manually after which only the valid ones, get compressed into big plastic blocks. These chunks of plastics are then ground into smaller parts and get washed by the same crushing machine. Consequently, another heavy machine transforms these cleaned parts into plastic pellets.

    The manufactured pellets subsequently are exposed to heat and get turned into plastic raw material. Finally, the raw materials get processed into different reusable products like shirts, pencils, and plastic containers. After the utilization of these products, they go again through the same process.

    Hoping to get feedback, please.

      1. Sorry for the late reply. You have a good command of English. Your essay is very easy to follow. I think you can get a 6.5.

        Overview: “start with” and “end with” are used to introduce the first and last steps only.

        Details Paragraphs:
        ✖“These chunks of plastics are then ground into smaller parts and get washed by the same crushing machine.”
        As you can see from the diagram, the crushing machine only crushes them. It doesn’t wash them.

        ✖ “Consequently”

        ✖“subsequently are”
        ✔are subsequently

        ✖“processed into”
        ✔made into

  11. The diagram depicts the information pertaining to steps involved in the conversion of used plastic into useful products.

    It can be clearly seen that in the initial phase plastic waste is thrown by the masses into dustbins, fron where it is collected by the recycling industry with the help of a big truck. After delivery to the recycling center, manual sorting is done, under this, material suitable for the further process is kept and rest idla recycled. Following this, the sorted plastic is compressed into blocks.

    Moving further, crushing of the material compressed in the previous step, is conducted along with its washing. In the sixth stage, pellets of plastic are formed, followed by the application of heat to transform these into raw material , which is then utilizes to manufacture, either plastic bottles, or bags. This process again starts with discarding of used products by people.

    Overall, it is a circular procedure, which starts again with each ending, this consists of mainly seven steps.

  12. The second portion of this task; if I write “Looking from an overall perspective, it is readily apparent that……..” instead of “Overall,” . So it will be correct ?
