The diagram illustrates the process of paper production and recycling through multiple steps.
Overall, this is a cyclical, multi-stage procedure which involves major prerequisites: felling, bark removing, chipping, pulping, pressing, rolling, printing, collecting, and ink removing.
Initially, wood is extracted from trees, and the bark is removed by a drum. Then, the remaining contents enter the chipper, which shreds the wood into wood chippings. From there, the fragments enter a refiner where it converts the pieces to pulp. The pulp later enters a machine which compresses them for further management. Subsequently, the pulp is manufactured into usable paper such as rolls. The rolls are then used to print out newspapers by a typer. After that, the used newspapers are collected and are gathered into cube-shaped blocks. Ultimately, the ink is extracted from the papers, and the remaining material enters the pulping machine again, effectively looping the cycle.
In conclusion, the picture effectively demonstrates the systematic process of paper manufacturing and recycling.
