India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.

The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.

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.

Denmark: Norway-based Geminor has appointed Per Mernelius as Country Manager for Geminor Denmark. He succeeds Kasper Thomsen in the position, who was recently appointed as the Operations Director for Geminor Group. Mernelius is currently the Country Manager for Sweden and he will add the new responsibilities to this role. Initially, he will be in charge of the Danish market for 12 months, pending the appointment of a new country manager in Denmark.

Mernelius commented “Denmark and Sweden are our two biggest downstream markets, with nearly 1Mt of imported refuse-derived fuel/solid recovered fuel in 2023. As such, many similarities open up for synergies in the coming year. An important factor is logistics, and how we can coordinate the two markets for more efficient operations. Our ambition is to grow further and to cater for the existing over-capacity within energy recovery in Scandinavia.”

Mernelius has worked for Geminor since 2016. Before this he worked for Sweden-based energy supplier Jönköping Energi. He is a graduate of the Swedish University of Agricultural Sciences.

Spain: Cemex España plans to install a new tertiary mill in its Alicante cement plant’s refuse-derived fuel (RDF) line. The project, called Molentis, is scheduled for completion in early 2025 and will cost €6m. The Molentis upgrade will help the Alicante cement plant to raise its RDF substitution rate by 8%, according to the producer. This in turn will reduce its CO₂ emissions by 6700t/yr. The Spanish Ministry of Industry, Energy and Tourism granted €4.4m toward the project to Cemex España under its Innovation and Sustainability Plan.

Cemex España director of operations Benjamín Cabrera said "Molentis will enable us to advance towards climate neutrality and position the Alicante factory at the forefront of new technologies in the decarbonised industry."

US: Eagle Materials has outlined its climate change mitigation successes in its 2023 Sustainability Report. During 2023, the company increased its production of blended cement products, including Portland Limestone Cement (PLC). It commenced a major CO2 reduction study with the US Department of Energy, and established a Greenhouse Gas Reduction Team to explore new clean technologies. Eagle Materials says that it is currently working to increase the use of alternative fuels at three of its cement plants.

Brazil: Secil subsidiary Supremo Secil Cimentos will invest US$20.3m in an upcoming expansion of its Adrianópolis cement plant. Commencing in July 2024, the expansion will raise the plant’s clinker capacity by 10% and enable it to increase its alternative fuel (AF) substitution rate from 25 – 30% to 40%, and eventually to 50% by 2030. To date, AF use at the plant has reduced its cumulative consumption of petcoke by 100,000t.

CEO Paulo Nascentes highlighted the transformative impact of the Adrianópolis plant on its host community, with its initial investment of US$176m and a subsequent US$41.7m in previous upgrades to date. "One of the reasons why the Paraná government allowed the plant was because Adrianópolis was very neglected. The arrival of Supremo transformed the city," he said.

Spain: Cementos Portland Valderrivas' Alcalá de Guadaíra plant has secured environmental clearance to use more alternative raw materials and alternative fuels (AF) in its cement production.

The company said "This achievement is a further boost to our sustainable work practices, respecting the environment and contributing to combatting climate change."

UK: Aggregate Industries has successfully removed gas duct sections from the electrostatic precipitation filter at its Cauldon cement plant in Staffordshire. This will make way for the installation of a new CTP Team process kiln bag filter, following an annual shutdown.

Cauldon plant capital expenditure manager Mark Powling said “The new bag filter not only provides the best available technology, but will enable the Cauldon plant to optimise its plant performance, driving its decarbonisation and alternative fuel strategies. Thanks to the project team for their efforts and hard work to date.”

India: Sagar Cements recorded sales of US$80.5m in the third quarter of the 2024 financial year, up by 16% year-on-year from US$69.3m during the corresponding quarter of the previous financial year. Cement sales volumes rose by 14% year-on-year. The Hindu BusinessLine News has reported that the growth allowed Sagar Cements to reduce its net losses by 57%, to US$1.22m.

Managing director Sreekanth Reddy said “Favourable prices prevailed in our key markets. As far as EBITDA and margins are concerned, we observed a significant enhancement on a per-tonne basis, consistent with our earlier projections.” Reddy added “We anticipate this positive trend to persist in the future, supported in part by higher utilisation levels of recently-acquired units and strategic initiatives aimed at promoting the use of green power, alternative fuels and the deployment of electric trucks and wheel loaders.”

UK: The World Cement Association (WCA) marked the achievement of an ‘historic’ global consensus for decarbonisation at the COP28 climate change conference in the UAE in December 2023 with a new call to global cement producers and suppliers. The association called on all participants in the industry to help promote developments in reduced-CO₂ cement production through enhanced connectivity and communication. It said that technologies like alternative raw materials and alternative fuels (AF), efficiency-enhancing process changes and carbon capture and utilisation (CCU) are widely applied, but unequally, applied in the global cement industry.

Regarding the disparity between different markets, the WCA said “This imbalance underscores the critical need for more research and development funding in emerging markets, where there is real demand for this kind of support as a crucial enabler of progress.” It added “We will join hands with our members and stakeholders to advance the low-carbon and sustainable development of the industry and contribute to building a clean, safe and beautiful world.”
