| Basic material | Description |
|---|---|
| Virgin Pulp | Derived from fresh wood, making sure high quality and brightness. |
| Recycled Pulp | Made from post-consumer paper waste, decreasing ecological effect. |
2. Pulping
The procured basic materials are transformed into pulp. This process can be done in 2 primary methods:

- Chemical Pulping: Uses chemicals to dissolve lignin, producing a finer paper quality.
3. Lightening
If white A4 paper is the end objective, the pulp should undergo lightening. Chemical agents are utilized to eliminate any recurring color and pollutants from the pulp.
| Bleaching Method | Description |
|---|---|
| Chlorine Bleaching | An effective approach but less environmentally friendly. |
| Oxygen Bleaching | A more environment-friendly option that minimizes chemical usage. |
4. Papermaking
The bleached pulp is diluted with water and sent to a paper device. Here, it is spread onto a moving wire screen, where excess water is gotten rid of, and the pulp fibers bond together to form a sheet.
5. Drying and Finishing
Once the sheet is formed, it is travelled through a series of heated rollers that eliminate the staying moisture. After drying, the paper goes through various completing processes, such as calendaring (smoothing) and cutting.
6. Quality assurance
