Heidelberg Materials France to trial carbon capture installation at Airvault cement plant
13 March 2024France: 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: 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.”
Cemex launches clinker micronisation method
05 March 2024Mexico: Cemex has launched a new process called clinker micronisation, developed at its Research and Development Center in Switzerland. The method enables cement producers to lower the clinker factor of their cement by up to 50%, while maintaining its strength. It also offers the additional benefit of allowing concrete users to reduce the proportion of cement in their mixes.
CEO Fernando González said “We are finding new ways to boost our decarbonisation roadmap in the production of cement and concrete. We remain committed to achieving our ambitious 2030 decarbonisation goals on the path to becoming a Net Zero company by 2050.”
NeoCem to build €50m clay calcination plant
27 February 2024France: 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.”
Ecocem to showcase Advanced Cement Technology at Buildings and Climate Global Forum
27 February 2024Ireland/France: Ecocem will showcase its Advanced Cement Technology (ACT) at the Buildings and Climate Global Forum in Paris on 7-8 March 2024. The French Government and United Nations Environment Programme (UNEP) will host the event, supported by the Global Alliance for Buildings and Construction (Global ABC). It aims to advance the climate outcomes of the United Nations Climate Change Conference (COP28) in 2023. Ecocem joins global policy-makers, industry stakeholders and international organisations as the event’s sole international cement technology company exhibitor.
Managing director Donal O'Riain said "The Buildings and Climate Global Forum is happening at a crucial moment for the planet. Urgent and deep decarbonisation of construction materials is essential to achieving the 2015 Paris Agreement targets.” He continued “Ecocem’s ACT low carbon technology can decarbonise the cement sector on a trajectory consistent with 1.5°C of global warming, the first major industry sector to achieve this feat. But we must now mobilise resolutely, rapidly and globally to deploy this technology. The first ambition should be a 50% reduction in CO2 emissions from cement by 2030. Technology is no longer the barrier."
Eqiom’s Lumbres cement plant upgrade to expand capacity by 57%
26 February 2024France: 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 NOx and SO2 emissions by 40% and 80% respectively. The producer plans to invest €300m, including €40m from France Relance funds.
Heidelberg Materials grows sales in 2023
22 February 2024Germany: Heidelberg Materials reported sales growth of 0.4% in 2023, to €21.2bn. The group saw its profits grow by 21%, from €1.72bn to €2.09bn. During the year, the company reduced its specific CO2 emissions per tonne of cementitious material by 3% from 551kg to 534kg and lowered its clinker factor from 72% to 70%.
