The diagram illustrates how plastic bottles is a man-made, 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 recyling 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 bown 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, wish creates plastic raw material,
Finally the raw material is made into different plastic products, including pens, bottels and reusable shopping bags, After these products are used they go through the recyling all over again
