The given process diagram depicts the various stages involved in the production of recycle paper from the used one. Overall, the paper recycling process involves four stages, beginning with making pulp of used paper and ending with manufacture of a new recycled paper.
Firstly, used papers are put through a conveyor belt and dumped in a box containing water and chemicals in order to make pulp of those papers. Following this, the next step filtering begins with the filtration of the unfiltered pulp to filtered pulp.
After filtering is complete, the clarified paper pulp is sent by a tube to a container with water and soap to be further cleaned. Air is pumped into the vessel and ink is removed. Then, additional cleaning is done before putting the filtered and cleaned pulp in a conveyor belt which then is flattened by heated rollers through which excess water is removed. Now, the new recycled papers are ready for distribution.
