Metsä Group´s Äänekoski bioproduct mill is the largest wood-processing plant in the northern hemisphere. The Äänekoski bioproduct began its operations in 2017 and reached its nominal capacity in August 2018.
The mill produces 1.3 million tonnes of pulp per year. Most of the pulp is exported, mainly to Europe and Asia. The bioproduct mill manufactures softwood and birch pulp for board, tissue and printing paper and speciality products.
The Äänekoski mill is called a bioproduct mill since it is increasing the product portfolio with new bioproducts, generating excess bioenergy, and using no fossil fuels. The mill utilises 100 per cent of its wood raw material as well as production side streams. In addition to high-quality pulp, it produces a broad range of other bioproducts, such as tall oil, turpentine, bioelectricity, product gas, sulphuric acid and biogas. Upgrading of lignin and manufacture of textile fibres from pulp are progressing at the research stage. We are studying several processes and product paths and will implement them gradually.
