’s innovation company Metsä Spring and Valmet have decided to continue the development collaboration related to 3D fibre products and to invest jointly approximately Euro 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.

The main raw material used to make the new products is renewable, sustainably-grown, and pure Finnish wood fibre. The 3D fibre products are recyclable. However, in case recycling is not possible, the material decomposes also biologically. Maximizing the energy and raw material efficiencies and minimizing the distribution chain logistics are enabled by the light structure of the material and by new manufacturing technology.

The short-term goal of the project is to develop a novel durable, environmentally-friendly, and easy-to-use food package. Based on a recent customer survey, products like this are in high demand on the market, and the demand will grow further in the future. The aim is set for high volume market segments.

The construction of the pilot plant begins in the autumn of 2020 and the pilot plant is expected to be ready for operation by the end of 2021. The pilot plant will be used for the continued development of both the manufacturing technology and the 3D fibre product. If the pilot plant phase validates the concept as sound, the next step would be the construction of a commercial factory in the following years. Such a factory would be built in Finland. The pilot plant phase is part of the ExpandFibre program.
