The diagram illustrates the process of producing paper from wood and recycling used newspapers into new paper products.
Overall, paper production begins with trees being cut down and processed into pulp, which is then turned into paper and used for printing newspapers. After use, these newspapers are collected and recycled through several additional stages, creating a continuous cycle.
The manufacturing process starts with the felling of trees. The bark is then removed in a rotating drum before the wood is cut into small chips using a chipper. Next, these wood chippings are sent to a refiner, where they are converted into pulp. The pulp is subsequently pressed and flattened before being rolled into large reels of paper. In the final stage of production, the paper is used for printing newspapers.
Once the newspapers have been read, they are collected for recycling. The used newspapers first undergo a de-inking process to remove the printing ink. After that, the cleaned material is pulped again to produce recycled pulp. This recycled pulp is then fed back into the pulp-pressing stage of the original production process. From this point onward, the recycled pulp follows the same steps as newly produced pulp, being pressed, rolled into paper and eventually used for printing newspapers again.
