Metsä Group’s innovation company Metsä Spring and Valmet have decided to continue the development collaboration related to 3D fibre products and hence, to invest jointly approximately EUR 20 million in a new R&D project. As part of the project, a greenfield pilot plant will be built on Metsä Group’s mill site in Äänekoski, Finland. When operational, the pilot plant will employ roughly 10 persons. The technology applied in the pilot plant converts wet wood pulp into final 3D fibre products without any intermediate steps. In other words, the new environmentally-friendly 3D fibre products are ready to be shipped to end customers as such.
