France: Ecocem has launched a new low-carbon advanced cement technology (ACT) cement, aiming for widespread adoption in European construction projects. The ACT range promises a clinker concentration of 20%, lower than the current norm of 35% minimum.

Jean-Christophe Trassard, Director, Marketing of Sustainable Innovation, said "We achieve competitive rates by controlling granularity, the fineness of grinding and admixtures. We have also greatly developed our thinking on the addition of additives in our formulations, which required more than fifteen years of R&D and the filing of six patents."

This product contains locally sourced additives, with the capability to adapt mixes to regional availability. The ACT cement is expected to reduce water usage by one-third compared to conventional concrete. An ACT-based concrete reportedly emits 198kg CO₂/t, a substantial reduction from the 614kg CO₂/t for standard concrete in France.

Gaining market entry for ACT required European technical evaluation and European assessment document certification, currently pending in the EU Official Journal. Trassard added, "As we are dealing with clinker rates below the standards, we had to go through this certification, which gives us a very good passport for the European markets. However, local administrative variations will have to be carried out subsequently."

In France, Ecocem has already applied for ATEX certification to facilitate deployment of the ACT range, expected later in 2024. Ecocem aims to include the ACT range in standard norms by 2026.

France: Saint-Gobain is intensifying its commitment to low-carbon cement and concrete additives. The group has invested in Fortera, a start-up developing a process for low-carbon cement production. Fortera's ReCarb process reduces CO₂ emissions by 70% in existing cement plants, contributing significantly to the goal of net-zero carbon cement production, especially when combined with renewable energy. Additionally, Saint-Gobain supports Ecocem, a leading company in low-carbon cement technologies in Europe, as a shareholder. Ecocem's ACT technology showcases a 70% reduction in carbon footprint compared to the average CEM II cement used in Europe.

France: Neo-Eco has developed a low-carbon cement binder from clay excavated during the Grand Paris Express project. The process, developed at IMT Nord Europe, involves flash-calcination at about 700°C, allowing it to replace part of the clinker and emit approximately five times less CO₂ than traditional methods. Neo-Eco's director, Christophe Deboffe, said that this new ingredient could constitute 30% of cement, maintaining the cost similar to traditional binders.

To commercialise this breakthrough, Neo-Eco established Neocem, a subsidiary based near Lille. Neocem has raised €23m to build a production plant in Saint-Maximin, Oise. Strategically located near waterways and Île-de-France, the plant will directly receive excavated materials from the Société du Grand Paris.

Starting in 2025, the facility will produce 100,000t/yr of flash-calcined clay, with potential to double its capacity in the future. Deboffe sees this as just the beginning, planning to establish more plants across France and Europe to meet the cement and ready-mix concrete industry's demand.

The clay supply is estimated to exceed 100Mt, ensuring a sustainable and ample source for the binder.

The facility is supported by the French government's ‘Première usine’ initiative under the France 2030 investment plan, with funding from investors like Bpifrance and CB Green. CB Green, based in Calais, is also developing a limestone filler production plant in Dunkerque with Ecocem, pointing to a future where cement could be composed equally of flash-calcined clay, limestone filler, and clinker.

France: Heidelberg Materials France plans to install a 1Mt/yr carbon capture system at its Airvault cement plant in the New Aquitaine. The Airvault cement plant is undergoing an upgrade, including the replacement of two pre-existing semi-dry lines with a new dry line and pre-calciner. This will reduce the plant’s CO₂ emissions by 30% per tonne, reduce its energy consumption by 10% per tonne, reduce its clinker factor and raise its alternative fuel substitution rate to 90%. CO₂ capture is set to commence in 2030. The project is one of several, under the GOCO₂ carbon capture, storage and utilisation (CCUS) cluster, which also includes installations at Holcim France’s Saint-Pierre-La-Cour plant and Lhoist France’s Réty lime plant.

Chair Dominik von Achten said “We started an ambitious modernisation programme for our sites in France several years ago, with a planned investment of more than €400m. With the integration of AirvaultGOCO₂, we are now adding a cutting-edge project in the field of carbon capture to our previous efforts, which will enable a further, massive reduction of Heidelberg Materials’ carbon footprint in France.”

Chief sustainability officer Nicola Kimm added “Our approach in Airvault is a perfect example of Heidelberg Materials’ strategy to implement dedicated carbon reduction roadmaps. We are taking every possible step to reduce CO₂ emissions: Phasing out fossil fuels, reducing the clinker content of our cements, and improving energy efficiency. To mitigate the remaining residual emissions, we rely on CCUS – as part of an integrated scheme and with our strong partners in GOCO₂.”

France: Hoffmann Green Cement Technologies has signed a commercial partnership with Groupe Tartarin, a French company based in the town of Vienne, which specialise in a wide range of ready-to-use cements. This agreement will see Hoffmann Green Cement's clinker-free cements supplied to Groupe Tartarin's network of cement plants. This collaboration is part of Hoffmann Green's strategy to expand its presence in Western France and emphasises its commitment to the decarbonisation of the construction sector.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said "This new commercial agreement with Groupe Tartarin, a key construction player in the Vienne region, illustrates our shared commitment to the decarbonisation of the construction sector. As well as highlighting our desire to work with local players to achieve this objective, this collaboration strengthens our position in the ready-mix concrete market and supports our commercial expansion with regional players, particularly in Western France."

Nicolas Tartarin, CEO of Groupe Tartarin, added "This partnership with Hoffmann Green reflects Groupe Tartarin's commitment to decarbonising its business while preserving the quality of its concrete. Thanks to this collaboration and the use of Hoffmann Green's clinker-free cement, we are able to implement an innovative and environmentally friendly solution in the construction of our buildings, while guaranteeing the quality we offer our customers today."

France: Fives Group has partnered with Holcim to decarbonise its cement production processes. Fives conducted successful hydrogen tests at the La Malle site in France, achieving over 50% hydrogen substitution in cement production. This result also enabled a significant increase in the use of alternative fuels while still maintaining cement quality. The group has also developed a digital model to tailor this process to each cement plant's unique requirements.

France: Representatives from the global cement and concrete industry will meet in Paris on 7- 8 March 2024 for the Global Buildings and Climate Forum. Industry leaders will seek to set out a framework for sustainable, decarbonised buildings.

Global Cement & Concrete Association CEO Thomas Guillot said “Our industry has been leading the way on decarbonisation through the implementation of our 2050 Net Zero Concrete Roadmap, and as our Roadmap sets out we are committed to fully decarbonising this essential material.”

Bruno Pillon, Chair the French cement association France Ciment, said “France and the whole world will still need to rely on cement and concrete for future infrastructure. But it’s really important that the cement and construction sectors, governments and suppliers all work together to achieve our net zero goal.”

France: Holcim has appointed Xavier Guesnu as the CEO of Lafarge France. He succeeds François Petry, who is leaving the group.

Guesnu started his international career at Legrand before joining Bain & Company in 2005. He joined Lafarge in 2010 as the head of strategic business development and mergers and acquisitions. Operational management roles followed first in eastern Canada as managing director from 2013, then as the managing director of Holcim Poland from 2018. He holds an engineering degree from the École des Mines de Paris.

France: NeoCem plans to build a €50m clay calcination plant at Saint-Maximin, Picardy. The company recently raised €23m in investments in its Series A funding round. The Le Journal des Enterprises newspaper has reported that the Saint-Maximin plant will enter operation in 2025, and will subsequently grow to 200,000t/yr in capacity. NeoCem aims to employ 100 people by 2030.

Head of industrial deployment Guillaume Luu said “To be used in concrete, limestone must be heated for several hours at 1400°C. Our clay-based binder generates CO₂ emissions of 120kg/t, compared to almost 1000kg/t of limestone binder, and our technology can transform all types of clays available. The idea is not to open new quarries, but to give a second life to materials already on the surface." He continued “The up-cycling of clays and their transformation into a low-carbon binder addresses several challenges for the construction sector. On the one hand, the reuse of clay waste, and on the other hand, the decarbonisation of the building materials sector.”

France: Eqiom plans to expand its Lumbres cement plant by 57% from 700,000t/yr to 1.1Mt/yr by 2026. The project involves the installation of a new kiln and aims to reduce the plant's CO₂ emissions by 20%, its fuel consumption by 35% and its NO_x and SO₂ emissions by 40% and 80% respectively. The producer plans to invest €300m, including €40m from France Relance funds.
