The diagram illustrates the plastic bottle recycling procedure and the different steps involved in this recycling process. Overall, the process of recycling plastic bottles has nine steps, starting from placing the bottles in designated bins to producing end-consumer products like bags, t-shirts, pencils and so on. As the illustration depicts, the first step of recycling plastic bottles begins with people placing used plastic bottles in specified recycling bins. Next, those bottles are collected and transported to recycling centres where workers sort out recyclable plastic bottles. Selected bottles are then compressed and converted into large blocks, which are, afterwards, sent through crushing machines. The crushing process produces small plastic pieces, which are then washed before being fed into a machine to make plastic pellets. In the next step, heat is applied to the pellets, which ultimately form the raw materials for producing various plastic-made consumer goods. Next, the raw materials are refined and rolled, which is used to manufacture end products like t-shirts, pens, plastic bottles, containers, and so on. To reiterate the recycling process, the end products are placed in the designated bins once they are torn out or used. It keeps the plastic recycling process going.
