The flow chart illustrates how waste paper is recycled.
Overall, there are 6 steps in the process, beginning with the collection of waste paper and ending with the production of usable paper. The principle of renewing paper is to remove all materials on the surface.
At the first stage, paper which is thrown away was collected from individuals and companies. Afterwards, it is classified by hand to get rid of inappropriate paper. Following this, paper is delivered to a paper mill before it is ready for the next stage.
At the fourth stage, all other materials such as staples are cleand, pulped from the surface of paper. Then, the process continues with “de- inking”, where inks and glues are eliminated. Both the fourth and fifth step are to ensure having completely cleaned paper before entering the final step. The process finishes by putting paper into a making machine, thus paper is totally renewed, and then reused.
