- Logs are processed into boards, with leftover wood converted into small chips.
- Wood chips are broken down into pulp through the addition of chemicals.
- Pulp is cleaned, pressed, dried, and formed into paper using machines.
- The finished paper is rolled and cut into various sizes for distribution.

The initial step in the wood processing process is cutting trees into logs, which are then taken to the mill for further processing.
Paper is made by converting leftover wood into small chips, breaking them down into pulp, cleaning the pulp, and then feeding it into paper-making machines. The pulp is sprayed onto a moving screen, pressed, dried, and finally cut into various sizes.
A significant threat to biodiversity is that 12,000 species of animals are now threatened with extinction, highlighting the urgent need for conservation efforts.
