kyllästämien

Kyllästämö is a Finnish term referring to a facility or process involved in wood preservation. The primary purpose of a kyllästämö is to treat wood with chemicals to protect it from decay, insects, and other forms of degradation. This process extends the lifespan and durability of wood products used in various applications, such as construction, fencing, and outdoor furniture.

The treatment typically involves impregnating the wood with preservatives under pressure. Common preservatives include creosote, copper-based compounds, and alkaline copper quaternary (ACQ). The specific chemicals used depend on the type of wood, its intended use, and environmental regulations. The process often involves vacuuming the wood to remove air, then forcing the preservative into the wood cells under high pressure. After impregnation, the wood may undergo a period of drying or further treatment to ensure the preservative is properly fixed.

Kyllästämö operations are subject to environmental regulations due to the chemicals used. Measures are in place to manage wastewater, emissions, and waste materials to minimize environmental impact. The treated wood is used in many sectors, contributing to the longevity of wooden structures and reducing the need for frequent replacements, which in turn can have resource conservation benefits. The term itself directly translates to "impregnation facility" or "treatment plant."
