The diagram illustrates the process of paper production and recycling. Overall, there are two main stages in making paper from wood and recycling used newspapers.
In the first stage, trees are cut down, and bark is removed from the trees. The bark is stripped off using a machine. After this process, the wood is broken into small pieces using a chipper, and then the wood chips are pressed into pulp using a refiner. The next step is pulp pressing. The pulp is pressed to remove excess water. The paper is used to print newspapers, after which it is rolled.
The next stage is the recycling process, starting with collecting used newspapers. Old newspapers are gathered for recycling, then the ink is removed from the paper. The last process is pulping. The cleaned paper is pulped again to create new paper material.
