The diagram given illustrates the way in which paper is produced from raw wood and recycled for reuse.
Looking at the illustration, it is immediately evident that paper manufacturing is a man-made linear process that requires both human labor and machinery. Additionally, there are ten main stages involved in this process, beginning with felling trees and culminating in the recycling of used newspapers.
In the first step, trees are felled, after which their bark is removed with the help of a drum. Following this, the logs are transferred to a chipper to be cut into small wood chippings. Then, these chippings are refined and turned into pulp. Once this has been completed, the pulp is pressed into sheets of paper, ready for further processing.
At the sixth stage, the pressed sheets are rolled into large rolls of paper. Next, these rolls are used for printing newspapers. Afterwards, old newspapers are collected and delivered for recycling. Having been collected, the newspapers undergo a stage of ink removal. The process ends when the cleaned paper is pulped again, thereby continuing the cycle of paper production.
