Indonesia: Suvo Strategic Minerals has reported successful laboratory tests in collaboration with Makassar State University (UNM) in Indonesia, transforming nickel slag into a ‘high-strength, low-cost and low-carbon’ cement, according to The Sydney Morning Herald. The trials used slag from PT Huadi Nickel-Alloy Indonesia's operations in South Sulawesi, achieving a compressive strength of 37.5MPa after seven days. The company is now looking to conduct further testing and will provide the results to PT Huadi, with the aim of forming a partnership for the commercialisation of low-carbon cement using nickel slag.

Aaron Bank, executive chair of Suvo Strategic Minerals, said “We are excited to have commenced this workstream in Indonesia testing the byproduct of one of the country’s largest mining companies, with our ultimate goal being to manufacture an environmentally-friendly and low-carbon alternative to Portland cement. Achieving up to 37.5MPa after only seven days is an outstanding first round trial result for the company and could provide an entry into a large industry.”

India: Thiruvananthapuram city Corporation has conducted a trial run of its refuse-derived fuel (RDF) plant at Sanmathi Park, Chala. The plant processes up to 1t/day of legacy waste, which is hard to segregate, to produce fuel for cement plants. The plant processes 40kg of materials per 15-minute cycle. Currently, non-recyclable materials are sent to Tamil Nadu cement plants. The government plans to establish at least one RDF plant per district as a permanent solution.

UK: A steel and cement co-recycling process developed at the University of Cambridge has received US$2.9m in seed funding. Cambridge Electric Cement is utilising slag produced during the steelmaking process, which uses electric arc furnaces instead of blast furnaces, as clinker for cement. The researchers are conducting a US$8.4m trial called Cement 2 Zero to test the production process, aiming to produce 110t of recycled cement during the two-year program.

Canada: Lafarge Canada and Geocycle Canada have successfully completed a pilot at the Lafarge Brookfield cement plant in Nova Scotia to produce clinker using recycled minerals from discarded material. This pilot can potentially cut CO₂ emissions by 60% of clinker. The new clinker product will be used to produce recycled cement in 2024.

CEO of Lafarge Canada David Redfern said "Our teams have been tirelessly working towards finding solutions to decarbonise our business in Canada. This new recycled-minerals clinker combines operational excellence with circular construction, building new and green from what is considered old and waste. This is a great example of how far we can go - the local team at Brookfield is certainly setting the tone for the industry in Canada."

Since May 2023, Lafarge Canada, Geocycle Canada and the Holcim Group Innovation Centre have been collaborating on a 100% circular production of clinker at the Brookfield plant. The new production method involves substitution of raw materials with lower carbon options from discarded materials, as well as alternative fuels produced from these materials. The trial was performed in February 2024 and cement from this clinker will be produced in 2024 for further testing and development of the technology.

UK: C-Capture has initiated a carbon capture trial at Heidelberg Materials’ Ketton cement works in Rutland, as part of its national 'XLR8 CCS' project aimed at accelerating low-cost carbon capture solutions in industries like cement and glass. The trial utilises C-Capture’s technology, which employs a solvent to selectively capture CO₂ from emissions. According to the company, this process does not rely on the use of amines, therefore requiring 40% less energy than conventional methods and reduces costs. The carbon capture solvent compatibility unit designed by C-Capture and partner Wood will test the effectiveness of this technology in removing CO₂ from flue gas emissions produced during the cement manufacturing process.

XLR8 CCS is funded with €2m from the Department of Energy Security and Net Zero’s €1.2bn Net Zero Innovation Portfolio. The funding is part of the €23m Carbon Capture, Usage and Storage (CCUS) Innovation 2.0 programme aimed at accelerating the deployment of next-generation CCUS technology in the UK. Additional private sector contributions support a €3.1m total.

C-Capture CEO Tom White said "Decarbonising industry is one of the most pressing global issues. C-Capture’s XLR8 CCS project is a critical step in the race to net zero as we work with our innovative technology and leading industry partners to demonstrate that an affordable carbon capture solution is a reality – even for industries that are difficult to decarbonise. We are incredibly proud to be working with our project partners which have strong commitments to decarbonisation and are early adopters of novel carbon capture technology."

Simon Willis, CEO of Heidelberg Materials UK said “Carbon capture is a critical part of our strategy to decarbonise cement production and essential if we are to reach net zero and help our customers achieve their own decarbonisation goals. Our venture with C-Capture is another example of our commitment to developing new technologies and, if successful, has the potential to be rolled out at other sites across the Heidelberg Materials Group.”

UK: First Graphene has announced a third trial at Breedon Group’s Hope Cement Works to test an optimised formulation of its PureGRAPH-CEM product under full-scale production conditions. The trial aims to further improve the performance of graphene nanoplatelets in cement production using practical experiences obtained from the previous two trials. The third trial is based on a PureGRAPH grade with a particle size distribution and morphology optimised for use in cement grinding mills, designed for direct addition to the mill without the need for additional equipment. The trial will last eight hours and involves close monitoring of cement fineness during the process. It will use just over 2t of the graphene product in up to 1000t of cement, according to the company. The trial is scheduled to start in the second quarter of 2024.

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.”

Taiwan: Taiwan Cement Corporation has signed a memorandum of understanding (MoU) with ThyssenKrupp Polysius. Under the MoU, the partners will implement carbon capture projects aimed at capturing 100,000t/yr (10%) of Taiwan Cement Corporation’s CO₂ emissions by 2030. This will involve the development of a new generation of pure oxygen carbon capture technology in Line 1 of Taiwan Cement Corporation’s Hualien Heping cement plant. This technology aims to increase the concentration of captured CO₂ to over 90% and reduce the energy consumption of carbon capture. The Hualien Heping plant project will conclude in 2026, with the commercialisation of the technology to follow before 2030. Taiwan Cement Corporation plans to supply its own captured CO₂ to various other industries, including industrial welding, chemicals and food processing.
