Metsä Group and ANDRITZ may build carbon capture facility at bioproduct mill

In Finland, Metsä Group and the technology company ANDRITZ will investigate the possibility of building a carbon capture facility in connection with the bioproduct mill. The work focuses on the capture of four million tonnes of carbon dioxide from a mill the size of the Kemi bioproduct mill. The Kemi mill is the largest wood-processing mill in the northern hemisphere.
The study will determine the optimal size of a recovery system that would be the most energy efficient combined with the bioproduct mill, as well as the cooling and logistical requirements of the system. The goal is to use the electricity, heat and steam generated in the bioproduct mill as efficiently as possible so that no waste heat is generated.
This work follows on from the carbon capture study launched in 2023. Carbon dioxide capture using an amine solution is an existing proven technology that has been used for decades around the world. However, combining this technology with a pulp or bioproduct mill is progressive.
