The diagram illustrates the process of recycling plastic bottles.
Overall, it has 9 stages, a man-made cyclical process. It begins with the transportation of materials, which are put into a trash container and ends with the final result of plastic being produced again.
First of all, the truck picks up the container with garbage and delivers the bottles to the recycling center, where a sorting employer divides plastics into two containers: useless and useful bottles. After that, the useful bottles are compressed into blocks to be crushed between two wheels into small pieces.
Following that, the small pieces are cleaned in water before they go through a production machine to make plastic pellets and deposit them into a clear container. From this, the pellets are heated for some time before they are formed into raw material and then produced into different types of products that can be used in manufacturing, ranging from clothes to containers and pencils. These items are themselves recyclable, and the process begins again.
