The diagram illustrates the methods of waste paper recycling. It is clear that there are six steps in the process of recycling waste paper, starting from the collection of waste paper and ending with the operation of paper-making machines.
The recycling process begins with the collection of waste paper, which is sourced from two categories: public paper banks and businesses. In the next stage, the collected waste paper is separated by hand; one side of the paper is graded while unsuitable paper is removed.
Following this, the graded paper is transported to the paper mill by vehicle. After that, the remaining graded paper is cleaned and pulped, with any unnecessary materials such as staples being removed.
The next step involves removing inks and glues from the cleaned paper, a process known as delinking. Finally, the delinked paper is then used by manufacturers to produce usable paper.
