Ekosampo Oy was founded in 1998. The company runs one of the world's first industrial-scale thermal treatment plants.

A customer-oriented operating method is fundamental to Ekosampo Oy's production. Finnish high-quality wood is the primary raw material. The wood is carefully sorted from Sahakuutio Oy's production for thermal treatment. Although pine is the major raw material, Ekosampo Oy also treats other woods. Around 90 % of production is exported, mainly to the EU, Asia, and Iran.
