The diagram illustrates the steps involved in the production of recycled paper.
Overall, the process consists of four main stages: making pulp, filtering, cleaning, and making paper.
Initially, used paper is collected and transported on a conveyor belt to be mixed with water and chemicals to remove any residue. Once the pulp is formed, it moves to the filtering stage, where unfiltered pulp is processed to separate larger impurities.
In the next stage, cleaning takes place. Here, the pulp is combined with water and soap, and air is continuously introduced to separate the ink from the pulp. The cleaned pulp is then mixed again with water and chemicals for further purification. Excess water and chemicals are removed, and the pulp is processed through heated rollers to shape it into sheets.
Finally, during the paper-making stage, the material is dried on a conveyor belt to remove any remaining water. The end result is recycled paper, ready to be reused for various purposes.
