Stock preparation

Show Subnavigation

In stock preparation, the fibrous materials of waste paper, wood and pulp are mechanically and chemically processed. Depending on the type of fibers used, paper is broken down into three groups: the wood-free or pulp-based group, the woody or wood pulp-based group and the waste paper-based group.

Besides fibrous materials, paper consists of water and auxiliary substances, both natural (kaolin, resin) or synthetic in origin (colorings)
