The diagram illustrates the process of paper production and its recycling, beginning with tree felling and ending with reusing newspapers.
Initially, trees are felled (step 1), and the bark is removed (step 2) using a drum. Next, the wood is chipped into small pieces (step 3) with a chipper. These wood chippings are then refined into pulp (step 4), which is subsequently pressed (step 5) to remove excess water. After that, the pressed pulp is rolled into paper (step 6) and used for newspaper printing (step 7).
Once newspapers are used, they are collected (step 8) and sent for recycling. The ink is removed (step 9), and the paper is pulped again (step 10), forming a cycle that allows paper to be reused efficiently.
Overall, the process consists of both manufacturing and recycling stages, emphasizing the sustainable use of raw materials.
