By replacing up to 70% of clinker — the key polluting ingredient in cement — with low-carbon SCMs (Supplementary Cementitious Materials), ACT significantly lowers the carbon footprint of cement (approximately 200 kg eqCO2/t compared to 600 kg eqCO2/t), while achieving the required strength, durability, and workability in the concrete it is used to make.
ACT is the result of a decade of research to develop a sustainable, low-carbon, low-cost, easy to produce, a globally scalable technology. It has been validated through successful industrial trials.
Low-carbon cements have been used effectively for decades, but the challenge has been scaling them.
ACT is a breakthrough technology precisely because it multiplies the low-carbon benefits for traditionally used low-carbon cements as well as new ones and allows them to scale as never before
Unlike many low-carbon cements or CCUS solutions still in early development stages, ACT is built for real-world deployment – fast, scalable, and designed to work within today’s infrastructure.
ACT cuts clinker use by up to 70%, replacing it with abundantly available, low-carbon materials like limestone and SCMs and uses them far more efficiently. It delivers the required strength, workability, and durability without the need to change manufacturing or jobsite practices, without a green premium. Its compatibility with global standards and infrastructure makes it viable across mature and emerging markets.

ACT doesn’t just reduce CO2—it re-engineers cement for performance, efficiency, flexibility and resilience.
It helps producers deliver more with less: less clinker, less energy and less disruption.
In a resource-constrained, high-demand world, that is groundbreaking.
cutting emissions and input costs
like limestone and SCMs, not supply-constrained or specialty components
in standard concrete applications
and transported by standard concrete mixers
from an operator perspective
at ready-mix and precast plants
ACT will accelerate access to scalable low-carbon, low-clinker, competitive cement technology and, if rapidly adopted, can deliver a 50% reduction in CO2 by 2030.
To support the rapid decarbonisation of the global cement industry, Ecocem will work closely with cement producers and make the technology as widely available as possible on an economically advantageous basis.
The rapid decarbonisation of the global cement industry just got real. We have the know-how to take cutting edge solutions from the lab, through production, to real world application. Read more about how we deliver the ACT solution, here.
