The diagram illustrates the sequential process of recycling plastic bottles.
Overall,it has 9 stages,a man-made cyclical process. It begins with the transportation of materials,which are putted into a trash container and ends with the producing end products .
First of all,the truck picked up the bin with garbage and delivered the bottles to the recycling center,where a sorting employee divided plastics into two containers:useless and useful bottles. Are 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 that,the pellets are heated for some time before they are formed into a raw material and then produced into different types of products that can be used in manufacturing,ranging from clothes to boxes and pencils. These items a themselves recyclable,and the process begins again.
