The Wisa chemical pulp factory in Pietarsaari is one of the largest of its kind in Europe. Due to investments in the factory’s recovery line, it is also the largest chemical pulp factory in the world when measured by unit size. The investment contract was conducted as a project management service and split into parts for several suppliers. For example, the machine deliveries were substantial. The machinery for the evaporation plant, soda recovery boiler and building, causticizing plant and lime sludge reburning kiln was supplied by Andritz.
Ruukki’s delivery to the project included a contract for the steel frame as well as pipe bridges, external wall elements and profiled wall sheets.
