Metsä Group’s innovation company Metsä Spring and Valmet Oyj have decided to continue the development collaboration related to 3D fiber 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 fiber products without any intermediate steps.

 

“Our objective is to develop a novel wood-based 3D fiber product, which can replace, for instance, packages made out of fossil raw materials. The pre-study phase with Valmet was a success. We have thus decided to accelerate the pace of development by constructing a pilot plant. I believe that our possibilities for developing a new significant added-value product for the Finnish forest industry are good”, says Jarkko Tuominen, head of the project at Metsä Spring.

 

The main raw material used to make the new products is renewable, sustainably-grown and pure Finnish wood fiber. The 3D fiber 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 a new manufacturing technology.

 

“As a technology leader, Valmet brings unique technology and product development capabilities to this joint development project. This collaboration project with Metsä Spring is an excellent opportunity to develop totally new solutions that support sustainability”, says Petri Rasinmäki, head of the Board and Paper Machines Technology Unit at Valmet.

 

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 programme.
