Koskisen Oy, which began its sawmill operations almost 110 years ago, has grown into a diversified wood processing company that processes all its procured wood into products ranging from bio-energy to industrial housing elements. Located in Kärkölä in Päijät-Häme, the company has a typical history for a Finnish wood industry company: it started with sawmill operations. The second generation was interested in expanding to new products, and the sawmill operations begun by Kalle Koskinen were soon extended to wood processing for the plywood, chipboard and construction industries. Now in its fourth generation, Koskisen Oy is a Finnish pioneer in the sawmill and wood panel industries, in thin plywood production and the manufacturing of element-based building construction components. The company has more than a thousand employees and turnover was EUR 270 million in 2017.
