Celebrating the 150th anniversary of the Finnish forest industry

It was on the banks of the Kymi River in 1872 that the Finnish forest industry, the growth of local prosperity and business life, and the story of UPM corporation began. At that time, the Verla and Inkeroinen groundwood mills, the Kymi and Kuusankoski paper mills and the Kotka sawmill were founded in south eastern Finland.

In 1872, a paper mill was also founded in Valkeakoski, where Walkiakoski Aktiebolaget started production in 1873, and in Pori, by the Kokemäenjoki River, the Seikku sawmill was established in 1872.

The operations of the Kymi mills began when, in February 1872, Kymmene Aktiebolag was established under the leadership of Axel Wilhelm Wahren, one of the most modern industrial entrepreneurs of his time. At the same time a decision to build a groundwood mill and paper mill was made. In January of the same year, Count Carl Robert Mannerheim together with more than 30 other shareholders, founded Kuusankoski Aktiebolag. More than twenty years later, Tampereen Kattohuopatehdas Oy, under the leadership of Rudolf Elving, built a groundwood mill and paper mill along the Kymi River in Voikkaa.

In 1904, Kymmene, Kuusankoski and Voikkaa merged to form Kymi Corporation. The company's expansion outside Kuusankoski began in the 1910s and its internationalisation twenty years later. Operations started at the current mill site in 1964.

Walkiakoski Aktiebolag operated in Valkeakoski from 1873 to 1934. The company later became part of United Paper Mills. The company's operations began when an office worker Carl Johan Helin, a pharmacist Edvard Julius Granberg and a merchant Carl Oskar Willgren established a groundwood mill and a paper mill with two paper machines in Valkeakoski. The mill was initially operated under the name E. J. Granberg & Co but was soon renamed Walkiakoski Aktiebolag. The groundwood mill and the paper mill started in 1873.
