sellutehtaan

Sellutehdas is a Finnish term that translates to "pulp mill" in English. A pulp mill is an industrial facility primarily engaged in the process of separating the cellulose fiber from wood or other fibrous materials. This cellulose fiber is the main component of paper. The process typically involves breaking down the raw material using mechanical or chemical methods to extract the usable pulp.

The wood used for pulp production is usually sourced from sustainably managed forests. Different types of pulp can be produced, including mechanical pulp, chemical pulp (like sulfite or kraft pulp), and semi-chemical pulp, each with varying properties suitable for different paper grades and other cellulose-based products. Mechanical pulping grinds wood chips, while chemical pulping uses chemicals to dissolve lignin, the substance that binds cellulose fibers together.

Pulp mills are significant industrial operations, often located near sources of raw materials and water. They play a crucial role in the paper industry, supplying the essential material for the production of paper, cardboard, and various other paper products. Modern pulp mills also often incorporate advanced technologies to minimize environmental impact, including water recycling and energy recovery systems. The output of a pulp mill is either sold as market pulp or used internally by integrated paper mills for paper production.
