The diagram illustrates how to recycle plastic bottles after using. Overall, there are nine stages to recycle plastic bottles, starting by throwing to the recycled bins and ending by producing end products.
The first operation consists of throwing the plastic bottles into the recycled bins that are prepared. Then, recycled trucks come and collect the recycled items. After arriving the recycling centre, workers there further sort them out into two kinds: reusable and not reusable. After that, those reusable plastic compressed into blocks during the fourth stage. The fifth stage consists of crushing and washing. At this moment, the blocks are crushed into pieces and then washed in the tanks.
Later, pieces of the blocks is put in machines to produce plastic pellets. The product is further heated under extreme heat to form raw material. Raw material is put into containers to shape the appearance during the ninth stage. Lastly, the raw material can be used to produce end products such as clothes, pencils and bottles.
