Oman: Middle East Calcined Clay and Netherlands-based Kaolin Group International plan to build a limestone calcined clay cement plant in Oman. The partners have hired Spain-based turnkey plant engineer IPIAC to supply equipment including its Plug and Clay clay calcination unit. The new plant will produce limestone calcined clay cement with 40% lower CO₂ emissions than ordinary Portland cement (OPC), according to the supplier.

IPIAC previously introduced the technology in Cuba and Ivory Coast, and is currently retrofitting it to a clinker line in Angola.

India: JSW Cement has appointed Finland-based Coolbrook to install its RotoDynamic Heater electric kiln technology at the Vijayagar steel works and slag and cement grinding plant in Karnataka. Press Trust of India News has reported that the partners expect the technology to reduce the CO₂ emissions of the plant’s slag cement.

Read about the applications for the RotoDynamic Heater in cement production in this Global Cement interview with Coolbrook CEO Joonas Rauramo.

US: Sublime Systems has acquired a site in Holyoke, Massachusetts, to build its first commercial-scale cement plant. The planned unit is expected to be commissioned in 2026, create 70 jobs, and will eventually have a capacity of 30,000t/yr. The selected site previously housed paper mills and is powered by local hydroelectric resources. The project is also being supported by a state tax credit from the Economic Development Incentive Program and local Tax Increment Financing from the City of Holyoke to offset property taxes. The commercial-scale plant is being developed as a stepping-stone before building a larger 1Mt/yr plant in the future.

Sublime Systems chief executive officer and co-founder Leah Ellis said “The same qualities that made Holyoke a world-class industrial hub in the past perfectly position it to now be the home for clean tech manufacturing of the future.” She continued, “The Water Street site exemplifies that in its ample space, industrial zoning, access to renewable hydroelectricity, utilities and even rail.”

Sublime Systems is commercialising an electrolysis cement production process that will manufacture cement at ambient temperature from a variety of calcium sources. Its Sublime Cement product received an ASTM C1157 designation in September 2023. The company has raised over US$50m from a consortium of climate technology investors, Advanced Research Projects Agency-Energy (ARPA-E) funding and strategic investor Siam Cement Group.

Germany: Ratings agency EcoVadis has awarded drives supplier Flender its Platinum medal for its performance across environment, labour and human rights, ethics and sustainable procurement metrics.

CEO Andreas Evertz said "With our commitment to sustainability and social responsibility, we have already achieved significant milestones. This excellent rating confirms our very good progress in the right direction. We are pleased with this but are also aware that there is still a long way to go. We aim to be pioneers in sustainability and inspire others - with full dedication and alongside our strong partners.”

Germany: Holcim Deutschland has announced for the ‘most extensive’ modernisation of its Beckum cement plant to date. Local press has reported that the modernisation will commence with the installation of a Euro20m pendulum cooler to replace the plant’s existing tube cooler. The new cooler will reduce the plant’s CO₂ emissions and make separated CO₂ better suited for capture, according to the producer. The Beckum cement plant is the site of an on-going carbon capture trial.

General manager Jan Kristof Peters said “We want to implement all construction work as quickly as possible and with as little noise pollution as possible for the neighbourhood. As in previous years, we ask for our neighbourhood’s understanding.”

France: Hoffmann Green Cement Technologies has announced the signing of its latest partnership agreement, with single-family home construction firm Groupe Trecobat. Under the agreement, Hoffmann Green Cement Technologies will supply its clinker-free alternative cement for Groupe Trecobat’s property developments throughout western France. Groupe Trecobat generated Euro203m in sales in 2023.

Hoffmann Green Cement Technologies co-founders Julien Blanchard and David Hoffmann said "We are delighted to be working with a leading player in single-family home construction such as Groupe Trecobat. This local partnership, which will enable us to develop a low-carbon offering for single-family home construction, accelerates our diversification and further strengthens our presence in the eco-responsible construction market."

Germany: Switzerland-based CO₂ mineralisation technology developer Neustark says that it sees major potential for recycling concrete from construction and demolition waste (CDW) to produce carbon-negative products using its process in Germany. Neustark inaugurated its first German plant, and 12th overall, at Marzahn in Berlin in late 2023. Capital Online News has reported that the start-up estimates that Germany generates 60Mt/yr of CDW concrete, but only recycles 600,000t/yr (1%). This contrasts with international CDW concrete recycling rates as high as 15% in Switzerland and the US.

The start-up, founded at the Federal Institute of Technology Zurich in 2019, currently absorbs 10kg/t of CO₂ in its recycled materials, but aims to reach 60kg/t. Its investors include Holcim.

Spain: Cementos La Cruz plans to build a new unit to produce reduced-CO₂ cement at its 1.5Mt/yr Abanilla grinding plant in Murcia. In a video posted on YouTube, the producer said that the new unit will produce cement using supplementary cementitious materials (SCMs) derived from industrial waste streams. Additionally, it will source 100% of its electricity consumption from biofuel-fired generators. Cementos La Cruz has secured Euro4.5m in European Union funding for the project.

General director Juan Luis Porrúa said that cement from the upcoming unit will have a specific carbon footprint below 200kg/t, and will eliminate over 400,000t of CO₂ emissions from Spanish construction in its first 10 years of operation.

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.”

Spain: Cemex España has announced its participation in the HYIELD consortium, which plans to build a waste-to-hydrogen demonstration plant at the producer’s Alcanar cement plant in Catalonia. The demonstration plant will process a total of 2000t of biogenic waste to produce 400t of green hydrogen for use as fuel, fertiliser and for other applications. The trial commands Euro10m in funding from the EU’s research and innovation funding programme Horizon Europe. Parent company Cemex believes that the technology being demonstrated at Alcanar has the potential to process 300Mt/yr of waste across Europe and produce 30Mt/yr of hydrogen.

Cemex’s Europe, Middle East and Africa regional president Sergio Menendez said “As part of its drive towards reaching net zero by 2050, Cemex is committed to partnering with like-minded organisations to explore the very latest innovations in more sustainable technology that can support the cement production process. We are proud to provide one of our cement plants in Spain as the location for the HYIELD trial and excited to see the outcomes from this research and development project.”
