India: UltraTech Cement has deployed five electric clinker trucks at its Dhar cement plant in Madhya Pradesh. Asian News International has reported that the trucks will convey clinker to the producer’s Dhule grinding plant in Maharashtra. The company expects the trucks to reduce its CO2 emissions by 680t/yr.
UltraTech Cement is committed to electrifying 500 vehicles across its operations by the end of June 2025.
Neustark sees potential in German market
04 January 2024Germany: 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.
World Cement Association calls on cement industry to promote low-carbon development through enhanced connectivity and communication
03 January 2024UK: 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.”
Sumitomo Osaka Cement signs agreement on Setouchi - Shikoku CO2 Hub
29 December 2023Japan: Sumitomo Osaka Cement, Sumitomo Corporation, JFE Steel, Kawasaki Kisen Kaisha and Woodside Energy have signed a memorandum of understanding (MOU) to jointly conduct a business feasibility study looking at setting up a CO2 hub in the Setouchi and Shikoku regions. It will examine how CO2 can be collected from different industries, transported to a hub port and then shipped to Australia for sequestration. A signing of the MOU was held at the ASEAN-Japan Economic Co-Creation Forum in the presence of Minister of Economy, Trade and Industry Ken Saito.
Sumitomo Osaka Cement operates two integrated plants in the Setouchi and Shikoku regions at Ako and Kochi respectively.
US: The Department of Energy (DOE) has awarded US$45.6m-worth of federal funding to carbon capture projects across US industries. Among the nine projects that received grants are Argos USA’s engineering-scale carbon capture project at its Harleyville, South Carolina, cement plant and Holcim US’ engineering-scale carbon capture project at its Holly Hill, South Carolina, cement plant. The National Energy Technology Laboratory has reported that projects will focus on technologies for CO2 capture and multi-modal transport via hubs.
DOE Fossil Energy and Carbon Management Assistant Secretary Brad Crabtree said “DOE is mobilising historic levels of private sector investment in the US to capture, transport and safely and permanently store hundreds of millions of tonnes of CO2 per year from our industrial and power sectors. These demonstration and pilot projects bring us one step closer to effective and responsible deployment of the carbon management infrastructure necessary to achieve our climate goals, while also providing good paying and jobs and health benefits to communities in every corner of the nation.”
Cemex Ventures raises stake in HiiROC
20 December 2023UK: Cemex’s corporate venture capital and open innovation unit Cemex Ventures has increased its stake in green hydrogen production technology developer HiiROC. Cemex Ventures described hydrogen as a ‘breakthrough approach’ to CO2 reduction in the cement sector.
Head of Cemex Ventures Gonzalo Galindo said "This news comes at a critical moment, when COP28 has brought the world together to address and refocus the climate agenda and buckle down on the responsibility of governments and private corporations to deliver on their decarbonisation objectives ahead of 2030. With our increased investment in HiiROC, we are especially proud to be number one in the use of hydrogen in the cement sector and are committed to keep scouting new ways to deploy hydrogen at a grand scale at Cemex’s 60 cement and grinding plants.”
Greece: The EU Innovation Fund has awarded a Euro234m grant to Titan Group for its IFESTOS carbon capture and storage (CCS) project. Titan Group said that the project, the largest initiative of its kind in Europe, marks a ‘monumental leap forward’ in its decarbonisation journey. The company hopes that the project will help to promote the deployment of carbon capture technology in Greece and beyond.
IFESTOS director and project leader Aris Tsikouras said “This agreement solidifies our group’s role as leaders in driving transformative change in industrial decarbonisation across Europe. IFESTOS encapsulates our commitment to sustainability and innovation, forging a path toward a cleaner, greener and more resilient future for the industry, in line with EU climate policy.”
École Polytechnique Fédérale de Lausanne recognised as Energy Transition Changemaker for LC3 limestone calcined clay cement project
19 December 2023Switzerland/UAE: The COP28 UAE Presidency named École Polytechnique Fédérale de Lausanne (EPFL) among its Energy Transition Changemakers in the Heavy Emitting Sectors category. EPFL won the prize for its LC3 limestone calcined clay cement, which replaces 50% of clinker content with calcined kaolinite clay and limestone. LC3 cement reduces CO2 emissions by 40% compared to ordinary Portland cement (OPC), and is a readily available solution that can be scaled worldwide. EPFL noted the special importance of LC3 cement for CO2 reduction efforts in developing countries, and sees it as having the potential to eliminate 500Mt/yr of global CO2 emissions by 2030. In a post to LinkedIn, the LC3 Project said that nine plants around the world currently produce LC3 cement, with a further 20 planned before 2025.
Holcim Azerbaijan to build cement terminal in Jabrayil in 2024
19 December 2023Azerbaijan: Holcim Azerbaijan plans to build a 2000t-capacity cement terminal in the Araz Valley Economic Zone in Jabrayil. AzerNews has reported that Holcim Azerbaijan will build the terminal in phases, commencing in 2024. The producer’s offering in the local market includes its ECOPlanet Inshaatchi and ECOPlanet Optimal reduced-CO2 cements. In a later phase, it will install a dry adhesive and ready-mix concrete batching plant at the facility. Planned investments at the site total US$2m.
Commercial director Sergiu Stoicov said "We aim to bring new methods to help the construction industry build sustainably. Through Inshaatchi and Optimal, we are taking a step in the race for CO2 reduction and the use of alternative raw materials. Holcim Azerbaijan is the first company in the Caucasus to offer green cement.”
Azerbaijan produced 3.42Mt of cement throughout the first 11 months of 2023. This represents a 4.1% year-on-year rise from 11-month 2022 levels. Meanwhile, clinker production rose by 10% year-on-year to 3.51Mt.
