The diagram illustrates the process of recycling plastic bottles. Overall, the process consists of three fundamental stages: collecting bottles, crushing process and completion. In the very beginning, plastic bottles were collected by manually from household garbages. Following this step, the bottles were transported to the recycling center and separated into two categories. While in the next stage, the bottles were compressed into blocks by machines, and then were crushing into pieces. After that, the pieces will be cleaned through the water systems, which is placed right below the crushing machines. The pieces eventually convert to plastic pellets, which will be consequently heated to form raw materials. The last stage is the raw materials from the previous step will be packaged and utilized to create garments, pencils, bottles,...And then, these items will be released to people to consume. Finally, these items will be in the garbage after consumption and the cycle will start over and over again.
