Belgium: Etex and Heidelberg Materials have joined forces on CEMLOOP XL, an industrial-scale project co-funded by the EU’s LIFE Programme that aims to revolutionise fibre cement recycling through a fully closed-loop process integrating carbon capture utilisation and storage (CCUS) technology. According to a press release by Etex, this will reduce CO₂ emissions in cement production by at least 20% and cut energy consumption in the process by 15%.

The project will combine the two companies' expertise to create a fully circular process where waste fibre cement is transformed into high-quality secondary raw material to produce low-carbon cement that will be reused in new fibre cement products. Etex, in collaboration with the Jacobs Group, is developing a recycled fibre cement paste (RFCP) process that converts waste from Etex’s production lines and the wider construction sector into reusable material and avoids landfilling. A new recycling facility in Hemiksem, near Antwerp, is under construction and scheduled for completion by mid-2026.

At Heidelberg Materials’ Lixhe cement plant in Liège, the company is implementing CCLIX, a carbonation process that treats RFCP with CO₂ captured from kiln exhaust gases. This produces carbonated RFCP (cRFCP), which regains cementitious properties and can partially replace clinker in low-carbon cement production. A dedicated carbonation reactor is set to be commissioned at Lixhe by the end of 2028.

Etex says that CEMLOOP XL will prevent 60,000t/yr of fibre cement waste, save 100,000t/yr  of raw limestone, and capture or avoid around 900kg of CO₂ for each tonne of RFCP produced. This process combines utilisation and storage in one step - the captured CO₂ becomes chemically bound within the new product, acting as a permanent CO₂ sink.

Eric Bertrand, chief innovation officer at Etex, said “By 2030, we aim for over 20% of our inputs to come from circular sources and to send zero waste to landfill. Fibre cement plays a central role in this transformation. For the first time, it will follow a fully circular journey - a milestone only made possible through strong partnerships like this with Heidelberg Materials.”

France: Ecocem has inaugurated a new €10m research and innovation centre to advance its low-carbon cement technologies and accelerate industry decarbonisation. The 3300m² facility will focus on developing scalable solutions to reduce reliance on clinker. It will build on Ecocem’s ACT technology, which the company says already enables up to 70% emission reductions, with the aim of providing the cement sector with a pathway to net zero by 2040.

Donal O’Riain, founder and global managing director of Ecocem, said “For 25 years, Ecocem has focused exclusively on low-carbon cement technologies. With ACT, our scalable low carbon cement technology close to commercial availability, the new centre will allow us to go further and faster. We will build on the 18Mt of CO₂ reductions already achieved and accelerate the development of solutions that can deliver net zero cement by 2040, 10 years ahead of schedule.”

France: Lafarge France has signed a nuclear production allocation contract (CAPN) with EDF to secure a long-term supply of low-carbon electricity for its cement plants. The deal allocates part of the capacity from EDF’s operating nuclear fleet to Lafarge France for more than 10 years under a cost and risk-sharing mechanism tied to actual volumes produced.

The partnership aims to cover part of the electricity consumption of Lafarge’s most energy-intensive sites in France, reducing the company’s carbon footprint while ensuring competitiveness and local presence, according to EDF.

Xavier Guesnu, CEO of Lafarge France, said “At Lafarge, we are already activating all levers to reduce the carbon footprint of cement, from research and development to the industrialisation of new low-carbon products and the use of alternative energies, such as biomass. This partnership gives us visibility and access to decarbonised energy, which are essential elements for continuing our investments aimed at large-scale production of very low-carbon or even carbon-neutral cements.”

Ghana: Continental Blue Investment Ghana (CBI) may receive up to US$20m from the International Finance Corporation (IFC) for a limestone calcined clay cement (LC3) plant in Tema, according to Ecofin Agency. The US$66.7m project is supported by Société Générale, Norfund and Denmark’s export credit agency EKF, with IFC’s board due to decide on 30 September 2025.

The company said that the facility operates with the ‘world’s largest’ flash calciner, and has a capacity of 400,000t/yr of calcined clay. With the funding, CBI plans to raise output from 600,000t/yr to 1.4Mt/yr, reducing clinker imports and lowering cement prices.

CBI is owned by Swiss holding company F. Scott in a joint venture with Heidelberg Materials, with minority stakes held by Norway and Denmark’s public funds and Danish equipment supplier FLSmidth.

US: Ecocem has obtained ASTM C1157 certification for its ACT low-CO₂ cement technology, confirming it meets or exceeds strength and durability benchmarks while reducing emissions and energy use. Unlike traditional cement specifications, the standard is performance-based, allowing for innovative formulations.

Founder and group managing director Donal O’Riain said “This is a significant moment for Ecocem and for low-carbon cement globally. Over the past 10 years our solutions have seen significant traction across Europe. The US is one of the largest cement markets in the world, and this certification will support integration into existing supply chains and offers a pathway for the sector to rapidly decarbonise through improved efficiency and without increasing costs or complexity.”

Ecocem is advancing its first North American project, a proposed terminal and milling operation at the Port of Los Angeles, aimed at establishing a reliable low-CO₂ cement supply chain in California. The company says that its low-carbon cement technology, ACT, cuts clinker content by up to 70% by using limestone and locally-sourced supplementary cementitious materials. The announcement follows recent regulatory approvals in France, new investment in production lines in Dunkirk, and partnerships with Bouygues, Vinci and Titan Group.

Algeria: The Minister of Industry Sifi Ghrieb has announced a project to build two new low-carbon cement plants in Djelfa and Relizane in central Algeria with a capacity of 1.5Mt/yr and 2Mt/yr respectively, according to Zawya news. An existing cement plant in Djelfa will also see its capacity expanded by 1.5Mt/yr.

The new projects will boost Algeria’s cement capacity to 42Mt/yr. It currently has a cement demand of 30Mt/yr and exports a surplus of 12Mt/yr of cement. Ghrief reportedly discussed plans to expand the Djelfa plant in March 2025 with a delegation from the China State Construction Engineering Corporation. A separate 2Mt/yr low-carbon cement plant, a partnership between local, UAE-based and India-based companies, is also under construction in El Milia, utilising slag and fly ash from a nearby power station and steel complex.

UK: Material Evolution has partnered with CRH subsidiary Tarmac to launch a pilot project to test applications of its heat-free, 85% reduced-CO₂ cement, MevoCem.
