Recent initiatives by Holcim, Cemex and Hoffmann Green show that the global cement industry is moving toward production models where reducing clinker content and expanding the use of ACS and GBFS form the foundation of decarbonisation.
Holcim launches CCS testing platform in France — a technological base for scaling GBFS‑based cements
Holcim has opened CaptureLab, the first industrial platform for testing and scaling different CO₂‑capture technologies on real cement plant emissions.
This directly supports the development of cements with high GBFS content, because CCS makes clinker reduction easier and strengthens the economic case for GBFS‑based low‑carbon cements.
Cemex sells over 1 million zero‑waste bags — supporting low‑carbon GBFS‑based cements
Cemex has sold more than 1 million SolmixBag water‑soluble cement bags in the Balearic Islands.
These bags are used for CEM IV/B (P) 32.5 SR ECO+SR, a cement type that typically contains a high proportion of GBFS.
Zero‑waste packaging further improves the environmental profile of GBFS‑based cements.
Hoffmann Green launches H‑CLAY — a technology that complements ACS and GBFS in low‑carbon cement
Hoffmann Green has introduced H‑CLAY®, a cold‑processed clay technology enabling 0%‑clinker cements.
It follows the same logic as ACS and GBFS: reduced clinker dependency, lower energy use, and minimal CO₂ emissions.
H‑CLAY expands the family of low‑carbon binders, while GBFS remains the most scalable and stable component.
Conclusions
- Innovations in CCS, circular packaging and alternative binders reinforce the role of ACS and GBFS in decarbonisation.
- GBFS remains the most scalable and proven SCM, benefiting from every step toward clinker reduction.
- ACS maintains its strategic role in infrastructure and road construction.
- The industry is moving toward a model where ACS and GBFS form the foundation of low‑carbon cement.
