India: Orient Cement has successfully commissioned Phase 2 of the new waste heat recovery (WHR) plant at its Chittapur cement plant in Karnataka. Reuters has reported that the new phase raises WHR power capacity at the plant to 10.1MW.

US: St Marys Cement won three national awards at the Slag Cement in Sustainable Concrete Awards 2023. The producer won the awards for supplying its slag cement for the construction of Wixom Assembly Park in Wixom, Michigan; of 333 North Water in Milwaukee, Wisconsin, and of Excellerate Manufacturing in Appleton, Wisconsin.

Thailand: Siam Cement Group (SCG) reported first-quarter sales of US$3.36bn in 2024, down by 3% year-on-year. The group partly attributed this to a decline in its cement volumes. Nonetheless, group earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 4% to US$341m. Special items in the group’s first-quarter 2023 results precipitated an 85% year-on-year decline in net income to US$65.5m from US$446m.

SCG recorded first-quarter CO₂ emissions of 5.99Mt, outstripping the Science-Based Targets Initiative (SBTi)’s recommendation of a 2.5% annual reduction. It relied on 47% renewable energy sources in its cement production.

Australia: Cement Australia has received a US$34.4m federal grant for a kiln upgrade to its Railton cement plant in Tasmania. The upgrade will allow the plant to raise its alternative fuels substitution rate. The project is funded by the government’s Powering the Regions initiative, with total investments valued at US$215m.

Australian Minister for Climate Change and Energy Chris Bowen said “This US$215m investment in Australia’s hard-to-abate manufacturing and mining facilities is about securing the future of high-quality, low-emissions products made right here. Northern Tasmania, Central Queensland and Western Australia have been industrial powerhouses for generations, and the government is ensuring that continues. As global markets change rapidly, we’re supporting Australian industry to not only survive but thrive with our world-class products that support regional jobs across the country.”

Australia: The Australian federal government has granted Adbri US$32.5m for a new front-end engineering and design study at its Birkenhead cement plant. The study will assess the possible installation of a new vertical roller mill and post-production blending system at the plant. InDaily News has reported that the proposed upgrade will increase the plant’s production capacity and help to expand its range of reduced-CO₂ cements. The funding falls under the government’s US$260m Critical Inputs to Clean Energy programme, which aims to help decarbonise the Australian economy by 2050.

CEO Mark Irwin said “With the Commonwealth’s support we have the potential to further accelerate the decarbonisation of our operations and products.”

Germany: Holcim Deutschland has broken ground on the construction of a new kiln line and CO₂ processing unit at its Lägerdorf cement plant in Schleswig-Holstein. The line will feature an OxyFuel kiln, supplied by ThyssenKrupp. ThyssenKrupp’s OxyFuel technology will assist in the capture of 1.2Mt/yr (nearly 100%) of CO₂ from the plant. The partners described the upcoming upgraded Lägerdorf plant as one of the world's first carbon-neutral cement plants.

Holcim Deutschland CEO Thorsten Hahn said "We're laying the groundwork for a sustainable world through cement. Cement is essential for our cities, factories, homes, bridges and beyond. As we transition towards renewable energy, we must also construct the foundations and structures for wind turbines and railway tracks. With our climate-neutral cement plant, we ensure that this vital building material remains accessible without further harm to the atmosphere."

ThyssenKrupp Decarbon Technologies’ chief strategy officer Cetin Nazikkol said “It’s vital to switch to climate-friendly processes. By enriching CO₂ by means of the pure OxyFuel technology we’ve developed, we help our customers capture almost all of the CO₂ arising in the production process and so reuse it in a sustainable manner. Given that global cement production is more than 4Bnt/yr, we see enormous growth potential for our innovative technology.”

UK: Heidelberg Materials UK has opened a new circular materials hub at its Appleford depot in Oxfordshire. The site will recycle construction waste for use in low-CO₂ building materials. The move advances the company’s strategy to conserve natural materials and support the circular economy.

Recycling managing director James Whitelaw said “Recycling, reusing and reducing the use of primary raw materials is crucial to reaching net zero. Our network of recycling hubs will allow us to provide the most sustainable products to our customers through circularity and innovation to enable building more with less.”

Switzerland: The Global Cement and Concrete Association (GCCA) is holding its Innovandi Global Cement and Concrete Research Network (GCCRN) Spring Week at the École polytechnique fédérale de Lausanne (EPFL) campus on 22 – 26 April 2024. 450 delegates from over 40 academic institutions will attend the event, featuring workshops, idea exchanges and progress reviews focused on the decarbonisation of cement and concrete by 2050. Topics include the use of AI, alternative materials and processes, concrete recycling, renewables, kiln electrification and carbon capture.

GCCRN industrial chair and Cemex global research development vice president and Davide Zampini said “If we are to reach our goal of net zero concrete by 2050, then we cannot do so alone. We need to explore as well as harness solutions and collaboration well beyond our industry. That’s why Spring Week is so important.”

GCCRN scientific chair Karen Scrivener said “Everyone here at EPFL is proud to be hosting this year’s Spring Week, anticipated as our largest gathering yet, marking a significant milestone in our journey toward net zero research.”

Indonesia: Siam Cement Group (SCG) subsidiary PT Semen Jawa used 24,000t of alternative raw materials in its cement production during the first quarter of 2024. These circular materials included bottom ash, fly ash and slag. This corresponds to 3% of its total raw material usage. Meanwhile, the producer co-processed 15,000t of alternative fuel (AF) during the quarter, representing a 20% AF substitution rate.

SCG Indonesia director Warit Jintanawan said that the developments "Not only enhance production efficiency, but also significantly reduces our carbon footprint. This is a testament to SCG's commitment to supporting Indonesia's climate goals, aiming to reduce greenhouse gas emissions by 32%, aligned with Enhanced National Determined Contributions."

Taiwan: Taiwan Transport and Storage unveiled its first electric truck, manufactured by Volvo Trucks, at a ceremony in Taipei. The unit will transport cement for Taiwan Cement, marking the first use of electric vehicles for construction material transport in Taiwan, according to the Taipei Times.

The electric truck unit will help to reduce aggregate carbon emissions by 32%, according to TTS chairman Koo Kung-yi. "We believe that Taiwanese companies can effectively reduce Category III CO₂ emissions through the use of electric commercial vehicles," Kung-yi said.
