Metsä Group and ANDRITZ to construct a demo plant for developing new lignin products
Metsä Group will construct a demo plant for lignin refining in connection with its Äänekoski bioproduct mill. The equipment will be supplied by technology group ANDRITZ. Construction will begin in Summer 2024, and the demo plant will be completed in late 2025. The plant’s daily capacity will be two tonnes of the lignin product. Lignin is a substance in wood that binds wood fibres together. In pulp production, lignin is separated from the fibres into black liquor in the chemical cycle and used as bioenergy. Lignin could also be used in chemical and material applications. Metsä Group and ANDRITZ will focus on developing the production process of the new lignin product and its integration with the bioproduct mill, as well as the product properties suitable for various end uses.
