Band 7.5 answer
The diagram illustrates how waste paper is turned into new paper in seven stages, from collection to final packaging.
Overall, the process begins with collecting and sorting paper and ends with the production of finished sheets, with most of the stages involving the cleaning of pulp.
First, waste paper is collected from homes and offices. It is then sorted according to quality and transported to a recycling plant. At the plant, the paper is mixed with water and chemicals in a large tank, where it breaks down into pulp.
Next, the pulp is screened to remove contaminants such as plastic and staples. Ink is then eliminated by washing the pulp and using air bubbles. Once the pulp is clean, it is pressed into thin sheets, which are dried by heated rollers. Finally, the dry paper is cut and wrapped so that it is ready to be sold.
