Major boost for Ecocem’s low carbon cement technology

A company specialising in low carbon cement technologies has gained an essential technical assessment required to achieve CE marking needed to market the product throughout Europe.

Ecocem’s ACT technology has obtained the European Technical Assessment (ETA) from the European Organisation for Technical Assessment (EOTA) for a new eco-efficient cement the company claims is “revolutionary”.

The ETA provides Ecocem with a route to full commercialisation for its ACT technology by 2026, and creates the opportunity for the cement and concrete industries to do the same. There is also the potential to scale globally since ETAs are recognised and highly respected internationally.

According to Ecocem, the path is now clear for the global cement industry to become the first major industrial sector to decarbonise on a trajectory compliant with the Paris Agreement to achieve a 1.5°C trajectory, without major changes to current working practices or excessive cost.

After water, concrete is the most used substance on earth. Cement, its critical ingredient, is responsible for almost 8% of global CO2 emissions – more than shipping, aviation and long-haul trucking combined.

Donal O’Riain, founder and managing director of Ecocem, said: “Historically the cement industry has struggled to achieve deep decarbonisation, due to absence of low carbon technologies capable of reducing the high CO2 emissions inherent in the cement manufacturing process.

“ACT technology provides the cement industry with a unique opportunity to halve emissions within the decade and become the first industrial sector to achieve a 1.5C decarbonisation trajectory

“This technical assessment is a game changer for the industry. It delivers the independent technical evaluation necessary to take ACT technology to European markets, directly and via licencing, to the cement, concrete and construction industries. The industry’s carbon transition just got easier, cheaper and faster. It is no longer possible to say we lack the technology or that costs are prohibitive.”

ACT technology is the culmination of a decade of research and innovation to develop scalable, sustainable, low-carbon, competitive cement technologies, Ecocem says.

The technology is currently undergoing rigorous trials, which the company claims are already demonstrating the carbon reduction possible using ACT – in effect, a 70% reduction in CO2 compared with the average European cement blend.

The trials have also demonstrated strong performance on key criteria, including strength, durability and concrete workability. Ecocem plans to supply the first ACT cement to customers in its European markets in the course of 2024, with full commercialisation by 2026.

Christian Clergue, European standards manager at Ecocem, said: “The technology to decarbonise the cement industry in line with the Paris Agreement exists. Thanks to the ETA, we now have the assessment that proves ACT’s safety and its performance. It is no longer theoretical, but a real, existing technology that can now start having an impact.”

Ecocem is partnering with key organisations in the cement and construction industry, including Groupe CB, Point P and Cemex France, to trial and develop the technology and ensure a continuous supply of materials.

To accelerate ACT’s delivery, Ecocem is scaling up activity at established production facilities in the Netherlands, Ireland, and France, where it will build a new mill to grind limestone at its Dunkirk plant in partnership with CB Green. In the US, the company is in the later stages of permitting for the construction of a plant on the West Coast.
