Capacity expansion project at the Husum folding boxboard mill progresses

Packaging Solutions

To meet the growing demand for sustainably produced packaging materials, Metsä Board announced last year an investment to increase the annual folding boxboard production capacity at its Husum mill by 200,000 tonnes.

To extend the current folding boxboard capacity, detailed engineering at the mill is ongoing and civil works have been in progress for several months. The board machine will be extended by 54 metres which requires an extension of the machine hall basement as well. Håkan Jonsson, project director, said: ‘We have built a building in the building to be able to do the extensive civil demolition works safely and at the same time to be able to continue production on BM1.’

The extension of the folding boxboard machine has been planned using simulation and 3D models. The dry end area of the board machine will be renewed, and the reel handling will be fully automated. There are also several improvements to the infrastructure to enable a smooth running operation at the site. All the main machinery purchases for the project have been undertaken, with Valmet as our main machinery supplier.

The Metsä Board project organisation is now manned with 24 people and on top of that, we have some individuals working part time on the project. More resources for installation management and commissioning activities will be added later. There are presently approximately 30 contractors working on site, mainly in civil works.

The start up of the renewed board machine is planned for the autumn of 2023 with full production capacity estimated to be reached by the end of 2025.

Husum is a competitive integrated production site and the ongoing renewal of the pulp mill will further improve the mill's production efficiency and environmental performance. It provides an excellent platform for increasing paperboard production capacity in a sustainable way in line with Metsä Board’ strategy.
