The diagram below demonstrates how used papers are recycled. There are four phases in the process of recycling, including making pulp, filtering, cleaning and making paper.
Overall, this process demands various chemicals and phases.
It can be seen that used papers are placed on conveyor belt machines and move into a tank, which is filling up with water and chemicals so that these papers turn into pulp. Next, the pulp will be filtered and then pour into a sink which has a mixture between water and soap inside. This mixture is affected by the air and continue to move to another tank, which has water and chemicals to clean that mixture. After that, the cleaned pulp is put on a conveyor belt. Finally, the pulp go through heated rollers and turn into the recycled paper.
