The diagram delineates the process through which newspapers are recycled into new paper products.
Overall, the recycling procedure encompasses four principal stages, spanning from the initial creation of unfiltered pulp to the final output of clean recycled paper.
Initially, the process commences with the production of unfiltered pulp, wherein materials are transported via a conveyor belt and subsequently amalgamated with water and chemicals to create a slurry. This mixture proceeds to the next phase, where it undergoes filtration, resulting in the creation of what is termed filtered pulp. During this stage, impurities are removed, and the pulp is prepared for further processing.
The subsequent stage, labeled ‘deink’, involves the introduction of additional water, soap, and air, which effectively removes the ink from the filtered pulp. Following this, further water and chemicals are added to enhance the purification process. Finally, the successfully processed mixture is placed upon a conveyor belt and subjected to a heated roller, culminating in the production of clean pulp, which is ultimately transformed into recycled paper.
