Pappírsframleiðsla

Pappírsframleiðsla is the Icelandic term for paper production. It is a significant industrial process that involves transforming raw materials, primarily wood pulp, into various types of paper products. The process typically begins with harvesting timber, which is then debarked and chipped. These wood chips are then converted into pulp through mechanical or chemical means. Mechanical pulping grinds the wood, preserving most of the lignin, which results in lower quality paper. Chemical pulping, often using the Kraft process, dissolves the lignin, yielding stronger, higher-quality pulp.

The pulp is then cleaned, bleached to achieve desired whiteness, and mixed with water and additives to form a slurry. This slurry is fed onto a large, moving screen or wire, where water drains away, leaving a mat of intertwined fibers. This wet mat is then pressed between rollers to remove more water and compact the fibers. Finally, the paper is dried over heated cylinders and can be further processed through calendering to smooth its surface or coated for specific applications. Different grades of paper, such as printing paper, packaging paper, and tissue paper, are produced by varying the raw materials, pulping methods, and finishing techniques. The industry plays a vital role in economies, providing essential materials for communication, packaging, and hygiene.
