The pilot project will evaluate a possible upgrade and expansion of the existing integrated pulp capacity from 370,000 tonnes to 780,000 tonnes per year, as well as a potential increase in board capacity of 120,000 tonnes.

The project would also significantly reduce fossil carbon dioxide emissions from production.

- The investment would give us the opportunity to grow and become even more flexible towards our customers to meet the increasing demand for sustainable packaging, says Hannu Kasurinen, EVP at Stora Enso's Packaging Materials division.

The preliminary project is expected to be completed by the end of 2021. Production could start at the earliest in the latter part of 2023. At present, Skoghall's mill has an annual capacity of 885,000 tonnes of packaging board.
