Given is a process chart illustrating materials and equipment used in four consecutive steps consisted in the manufacture of recycled paper.
• First of all, shredded paper collected in tubs are placed on a conveyor belt that transfers tubs to a container. Then, once the waste paper scraps are poured down, they are immersed in water and chemicals to breakdown the paper fiber materials. This activity turns the paper materials into a slurry substance, a process termed as pulping. When pulp is produced, it is subsequently passed through a series of screens.
• After the filtering process, the next process involves putting the clean and homogeneous pulp in a blender made up of water and soap to enhance purity. At this point, air will be infused while ink will be discharged by a tube. The cleaned pulp will drain through a pipe into the last container to be submerged into water and chemicals, after which, it is put to dry on a flat conveyor belt and flattened to form long rolls of continuous sheets of paper.
In brief, the whole recycling process for waste paper takes four steps involving pulping, filtering, cleaning and forming. (192 Words)
