In addition to pulp, the Äänekoski factory produces bio-products such as pine oil, turpentine and biogas. Metsä Group has invested 1.2 billion euros in the new factory, which is the largest investment in the history of Finland’s forestry industry. Uponor Infra delivered most of the project’s municipal infrastructure – the water, sewage and storm water pipes, the wells, and their parts. The deliveries also included an over one-kilometre-long Weholite outfall pipe for cooling water.
