The diagram illustrates the process of making paper from trees and how used paper is recycled into new paper.
Overall, the first stage begins with cutting trees and turning them into paper. The second stage involves collecting old paper, cleaning it, and reusing it to make new paper.
The process starts with radiata pine trees. The trees are sent to a de-barking drum where the bark is removed. Then, the logs are chopped into small pieces using a chipper. These pieces are processed in a thermomechanical refiner , where they are softened with heat and water to create pulp. Finally, the pulp is sent to a paper-making machine, which produced rolls of paper, such as new sprint.
The recycling process begins with collecting used paper, like old newspaper, through kerbside programs. After collection, the paper goes through a de-inking process to remove ink and otherb substances. It is then cleaned further with fine screening to ensure the pulp is free from impurities. The recycled pulp is mixed with fresh pulp and water in a thermomechanical and recycled pulp mix, and the mixture is used in the paper-making machine to produce new paper.
