Recycled fibres can be divided into four groups:
- Damaged paper e.g. transportation damaged paper that has never been used, or paper that was already scrapped at the mill.
- Scrap trimmings, end rolls and unprinted discarded paper from printing plants and converters.
- Office paper, computer reams, books and higher-quality printed materials.
- Newspapers, magazines and catalogues as well as paper recycled from households.
