Boliden Commits SEK 5.5B to Mine Expansion and Low-Carbon Cement Tech
Event summary
- Boliden will invest SEK 4B in a new hoist system at Garpenberg mine, operational by 2029, to sustain 4.5M tonnes/year production beyond 2030.
- SEK 1.5B allocated for an industrial demonstration plant at Rönnskär to produce SCMentum, a low-carbon cement alternative with <5% CO2 emissions of traditional cement.
- Garpenberg's environmental permit for 4.5M tonnes/year production is under appeal, while exploration continues to expand mineral reserves.
- SCMentum plant construction will run from 2026-2028, with production capacity of 280k tonnes/year meeting Boliden's IRR requirements.
The big picture
Boliden's investments reflect a dual focus on extending the lifespan of its core mining assets while diversifying into lower-carbon construction materials. The SEK 5.5B commitment underscores the mining sector's push toward both operational scalability and ESG-aligned product innovation. Success in these areas could position Boliden as a leader in sustainable mineral extraction and alternative cement technologies.
