The flow chart depicts the process used in waste paper recycling. Overall, the process involves six main stages, beginning with the collection of waste paper and ending with the production of usable paper.

In the initial stage of the paper recycling process, waste paper is collected from a variety of diverse sources, mostly from public paper banks and businesses. The gathered paper is then manually sorted and graded, whereas inappropriate paper is eliminated and only acceptable paper is saved for recycling. The recyclable paper will be sent to the paper mill for additional processing in the third stage.

In the fourth stage of the procedure, the paper is cleaned and pulped. Also, undesirable items such as staples are removed from the paper after it has been cleaned. Following that, at the de-inking stage, all traces of ink and glue are removed from the paper. Finally, the cleaned material may be processed in a paper manufacturing machine, resulting in useable paper.
