Ambuja Cements to use Coolbrook’s RotoDynamic Heater
India: Ambuja Cements has started a strategic partnership with Finland-based Coolbrook to use its RotoDynamic Heater (RDH). The technology uses renewably powered electrical heat to replace or reduce the amount of fossil fuels used for reaching high temperatures in cement kiln pre-calciners. No indication of the price or which cement plants will be upgraded with the equipment has been disclosed. The deal is intended to help Ambuja Cements meet its targets of reaching an alternative fuels thermal substitution rate of 28% and a renewable energy rate of 60% by 2028.
Ajay Kapur, CEO - Cement Business, Adani Group, said, “We continuously seek out innovations which drive efficiency and decarbonisation across our cement manufacturing value chain. Leveraging our Adani Group’s green power generation capabilities, we will be able to reduce fossil fuel dependence, costs, and emissions, ultimately delivering the best value for our stakeholders.”
SCG expands production of low-carbon cement in Vietnam for export
Vietnam: Thailand-based Siam Cement Group (SCG) says it is expanding the production of its SCG Low Carbon cement product in southern Vietnam. It plans to export up to 8000t/day of the product to the US, Canada, and Australia, as well as supplying local green-procurement projects, according to the Vietnam Business Forum. The company says its low-carbon cement reduces CO2 emissions by up to 20%, compared to regular products, through the use of alternative fuels, renewable energy sources and installing waste heat recovery (WHR) units at its plants. SCG formally launched SCG Low Carbon Super Cement in the country in July 2024.
PPC Zimbabwe warns of market disruption caused by imports of cement
Zimbabwe: PPC Zimbabwe claims that the country could lose an estimated US$50m/yr in foreign currency if imports of cement continue to enter the market at the current rate. Albert Sigei, the managing director of PPC Zimbabwe, made the comments at a press conference, according to the Herald Zimbabwe newspaper. He said that up to 45,000t/month of cement is being imported at present. Sigei added that the local cement manufacturers have sufficient production capacity to meet local demand. The installed cement grinding capacity is around 3Mt/yr compared to an estimated demand of 1.8Mt/yr.
In October 2023 the government issued temporary permits for cement imports during a shortage. The import permits were then discontinued in March 2024 when local production increased. However, smuggled cement reportedly continues to enter the market.
Raysut Cement notes excess supply in Oman
Oman: Raysut Cement says that production overcapacity in neighbouring countries has led to excess supply in the local market. This in turn has placed “pressure” on cement prices. The company added that exports to the Maldives, Yemen and east Africa had also slowed due to regional political instability, negative currency exchange effects and higher competition. The cement producer’s revenue fell slightly year-on-year from US$128m in the first nine months of 2023 to US$127m in the same period in 2024. However, its net loss grew from US$8.71m to US$14.6m.
Chile: Cementos Bío Bío (CBB) concludes negotiations with Mississippi Lime Company (MLC), according to Diario Financiero. Earlier in November 2024, MLC presented a non-binding offer of US$1.89 per share for 100% of CBB, valuing the company at almost US$500m.
Following this, Yura has now increased its offer to US$1.48 per share, valuing CBB at US$390m, after its original proposal ‘lost attractiveness’ to MLC’s offer. Yura aims to increase its stake to 40% in the company.
MLC said "After months of due diligence and review of the company's operational and financial performance, MLC and CBB's principal shareholders shared a non-binding letter of intent in May 2024 subject to conditions. That indicative offer, and its conditions, expired during this year. The revised indicative offer [from Yura], which is subject to all of the terms and conditions set out in the non-binding letter of intent, attributes an equity valuation of US$400m to CBB.”
Zanini Renk receives repeat order from St. Marys Cement for upgrades to Michigan plant
US: Zanini Renk has received a repeat order from St. Marys Cement for four additional gearboxes at its Charlevoix, Michigan plant. In 2016, St. Marys Cement's Charlevoix plant began a US$130m upgrade to expand the plant's infrastructure. The project scope included adding a new finish mill, an additional kiln and a new coal grinding system. The 2016 upgrade at St. Marys Cement expanded the Charlevoix plant’s cement capacity from 1.4Mt/yr to 2Mt/yr.
The initial order for a Zanini Renk gearbox was for installation in its vertical roller mill. Zanini Renk completed the gearbox installation in 2022. The first new gearbox has been in operation since January 2023 and the other two new gearboxes will be delivered at the end of November 2024. Installation is expected to be completed by March 2025 and by April 2025.

Armenia extends cement and clinker import restrictions
Armenia: The Armenian government has extended restrictions on the import of cement and clinker from Iran and ‘other countries’ for another six months on 28 November 2024.
The restrictions were first adopted on 13 January 2022 and have been repeatedly extended since then. The latest decision takes effect on 20 January 2025 and is valid until 20 July 2025.
As a result, domestic cement production increased to 1.14Mt in 2023, a rise of 13% year-on-year, while clinker imports rose by 125,200t (19%) and cement imports increased to approximately 270,000t. During the first eight months of 2024, cement imports rose to 305,100t, a 260% increase compared to the same period in 2023, due to lower Iranian cement prices. Concurrently, local cement production declined by 31% to 485,900t in the first half of 2024.
US: Heidelberg Materials North America has entered into a definitive purchase agreement to acquire Giant Cement Holding, a cement producer on the US East Coast focused on using refuse-derived fuels, for US$600m.

The transaction’s assets in the Southeastern US include an integrated cement plant with a capacity of 800,000t/yr in Harleyville, South Carolina, a network of four cement terminals in Georgia and South Carolina, and a joint venture deep-water import terminal in Savannah, Georgia. Assets in the New England area comprise a cement and slag terminal in Newington, New Hampshire, and a deep-water import terminal in Boston, Massachusetts. The transaction also includes Giant Resource Recovery, an alternative fuel recycling business with four facilities in the Eastern US.

Eagle Materials awards contract to thyssenkrupp polysius for modernisation of Laramie plant
US: Eagle Materials has awarded thyssenkrupp Polysius a contract for the modernisation and expansion of its Laramie, Wyoming cement plant. The modernisation project will result in an expansion of the plant's manufacturing capacity to approximately 1.1Mt/yr of cement. The project also includes the installation of an alternative fuel substitution system. The modernisation of the cement plant is expected to deliver benefits such as cost reductions, achieved with lower-cost alternative fuels and natural gas, simplified maintenance and improved operational efficiencies. The production expansion from the new finish mill will supplement the grinding capacity of the existing plant, which already operates with an integrated polysius booster mill. The polytrack ECO cooler will facilitate heat recovery and clinker cooling while improving process reliability. The project, which has received primary regulatory approvals, is slated to commence immediately [in November 2024], with construction scheduled for completion by the second half of 2026.
