Mercer International Inc. announced that its subsidiary, Mercer Peace River Pulp Ltd., in partnership with Svante Technologies Inc., has commenced operation of a carbon dioxide (CO₂) capture demonstration unit at the Mercer Peace River pulp mill in northern Alberta. The project aims to evaluate Svante's solid sorbent carbon capture technology on biogenic CO₂ emissions from the mill's recovery boiler flue gas. The demonstration phase is expected to last approximately six months and is designed to gather technical and operational data to inform future engineering phases and potential commercial-scale deployment. Any further development beyond the demonstration phase will depend on the results and additional economic, technical, and commercial considerations.
