Smurfit Westrock has launched a consultation process that could lead to the closure of its SSK paper mill in Birmingham, UK, as the group reviews its manufacturing footprint amid challenging market conditions.
The company said the move reflects sustained external pressures and a need to optimise its operations to remain competitive in the long term. The consultation, set to begin on May 15, will run for six weeks before a final decision is made.
The SSK mill produces around 200,000 tonnes per year of fluting and linerboard, supplying the UK and Irish corrugated packaging markets. Under the proposed plan, production would be transferred to other facilities within Smurfit Westrock’s European network.
The company indicated that consolidating output across its existing assets would allow it to maintain service levels while strengthening efficiency and supporting future investment priorities.
“Embarking on a consultation process is a difficult but necessary decision to ensure we are aligned with market realities and to strengthen our long-term position,” said Pim Wareman, CEO of Smurfit Westrock Recycled Paper Cluster Europe.
He also acknowledged the workforce at the Birmingham site, highlighting their contribution over many years.
If the closure proceeds, approximately 130 employees would be affected. The company said it plans to provide support measures, including career transition assistance and potential redeployment opportunities within the group where feasible.
The review comes as European containerboard producers continue to adjust capacity and cost structures in response to weaker demand and ongoing margin pressure across the sector.
