The picture shows the process of recycling paper.
Overall, the process comprises four main stages (making pulp, filtering, cleaning, and making paper). Starting from making pulp from used paper, through filtering and cleaning, to completely recycled paper. The process is a complex one, which requires much time and special equipment to complete.
The process begins with the used paper being conveyed on a belt into a large dish that has water and chemicals in it, and this helps to clean the paper. Then, it is filtered to eliminate germs. Afterward, the filtered pulp is placed in a container with water, soap, and air to expel inks. During this stage, an air pump is installed, creating bubbles so that the ink rises to the surface, from where the ink is then removed through another pipe. This step is essential to ensure the pulp is free from any residual printing substances.
The process then moves to the final stage, during which clean pulp is passed through heated rollers for water loss. After this step, the paper is ready for use.
