| Basic material | Description |
|---|---|
| Virgin Pulp | Stemmed from fresh wood, ensuring high quality and brightness. |
| Recycled Pulp | Made from post-consumer paper waste, lowering environmental impact. |
2. Pulping
The procured raw materials are transformed into pulp. This process can be performed in 2 primary methods:
