Brazil: Votorantim Cimentos grew its revenue and earnings in 2024 but its net income dropped significantly due to interest rate volatility. It noted ‘positive performance’ in its Europe and Asia region and a stable market in Brazil. It attributed its mounting earnings to its balanced portfolio, revenue in Europe and Asia, operational efficiency, reduced costs and new business.

The group’s net revenue grew by 3% year-on-year to US$4.69bn in 2024 from US$4.53bn in 2023. However, revenue fell slightly in local currencies due to negative exchange effects, particularly in North America. Cement sales volumes rose by 1% to 35.4Mt from 34.9Mt. Adjusted earnings before interest, taxation, depreciation and amortisation (EBITDA) increased by 16% to US$1.14bn from US$0.99bn. Earnings rose in all regions except for Latin America due to a ‘challenging’ market in Uruguay and lower prices in Bolivia. Despite this, its adjusted net income dropped by 17% to US$383m from US$461m.

“We ended the year with record-high operating results, supported by our geographic, product and business diversification, in line with our strategic mandate,” said Osvaldo Ayres, the group’s global CEO. The company invested over US$550m in 2024 towards decarbonisation, competitiveness and new businesses. A further US$880m investment plan in Brazil to 2028 was announced in early 2024. Ongoing projects include upgrades supporting higher thermal substitution rates at the Xambioá plant in Tocantins state and the Salto de Pirapora plant in São Paulo. A new 1Mt/yr cement grinding unit is being built at the Salto de Pirapora site. Construction of this project is scheduled for completion in the second-half of 2025. A new 1Mt/yr cement grinding unit was also announced at the Edealina plant in Goiás. This project is expected to be completed in the first half of 2026.

Votorantim also revealed that it paid around US$190m to the Administrative Council for Economic Defense (CADE) at the end of 2024 in connection with an agreement to end all administrative and judicial litigation. It said “We definitively resolved all pending disputes with CADE. We did not acknowledge, at any time, having committed any unlawful act or engaged in any anticompetitive behaviour.”

US: MTR Carbon Capture says that St Marys Cement’s Charlevoix plant in Michigan will be the first cement plant in the world to deploy its Polaris polymeric membrane-based technology. The pilot project aims to capture 3t/day of CO₂ during a six month testing period. It intends to demonstrate that a 95% CO₂ capture rate is achievable.

US-based Membrane Technology and Research (MTR) specialises in the development and production of membrane-based separation systems for the petrochemical, natural gas and refining industries. The company was set up in 1982 and has its headquarters in Newark, California.

India: Star Cement has successfully commissioned a 7MW air-quenched cooler waste heat boiler at its newly operational cement plant in Lumshnong, Meghalaya. increases the plant’s total waste heat recovery (WHR) capacity to 19MW. The WHR project aims to improve operational efficiency and reduce environmental impact.

Ethiopia: Dangote Cement will invest US$400m to restart the second production line at its Mugher cement plant, doubling the capacity to 5Mt/yr. The plant became operational in 2015, but has since faced challenges, including recurrent violence in the region, according to Bloomberg.

Aliko Dangote said that the expansion project is expected to be operational ‘within the next 30 months’.

India: UltraTech Cement has commissioned an additional 0.6Mt/yr grinding capacity at its integrated Sonar Bangla plant in West Bengal. It said the upgrade would help it meet cement demand in East India and enable it to increase its blended cement ratio. The company says that its domestic cement production capacity is now 166Mt/yr with an additional 5Mt/yr overseas.

Pakistan: Thatta Cement has signed a memorandum of understanding with China-based Qing Gong Construction Group to build a 5000t/day production line. They concluded the deal during a state visit by President Asif Ali Zardari to China, according to the Radio Pakistan. Other agreements were also signed in sectors including renewable energy.

Zimbabwe: South Africa-based Robtek is working on a ‘refurbishment’ project at Khayah Cement’s integrated plant in Harare. The project work on the kiln includes replacing 10 planetary coolers, installing 23m of kiln shell sections and refurbishing eight support rollers. Work on the raw mill includes replacing trunnion bearings, overhauling raw mill bearings, upgrading the internal diaphragm and head wall liners and installing a new double-flap valve to replace the star feeder.

Pakistan: Thatta Cement’s has increased its cement dispatches in the first half of its financial year despite a general reduction in the local market. Its cement despatches grew by 12% year-on-year to 254,000t in the six months to 31 December 2024 from 226,000t in the same period in 2023. The company’s net sales rose by 23% year-on-year to US$13.9m in the six months to 31 December 2024 from US$11.3m in the same period in 2023. It attributed this to a “…substantial increase in the retention price.” Its profit after tax tripled to US$4m from US$1.3m.

The cement producer said that it installed a 5MW solar power plant during the reporting period. It also expects to complete a 4.8MW wind farm in early 2025. The company started operating a new pre-crushing system for its cement grinding mills, supplied by Sinoma-Liyang Heavy Machinery, in mid-January 2025.

Saudi Arabia: City Cement Company has signed an agreement with the National Electricity Transmission Company to build a 106MW transmission station at its Nisah plant. Mist News has reported that electricity transmitted via the station will supplant oil generators at the plant. Construction is scheduled for completion later in 2025.

China: The Conch Zongyang Line 4 preheater modernisation project, based on KHD technology, has been selected as a pilot project under the Sino-German Energy Efficiency Improvement Demonstration in Key Industries programme. The initiative will be executed by KHD, its parent company AVIC International Beijing, and Conch Group’s research and development department. Results are expected by the end of 2025.

The programme stems from a 2023 agreement between China and Germany on climate change and ‘green’ transition cooperation. The programme was announced in 2024. It evaluated 12 candidate projects before selecting the Conch Zongyang project for its integration of technologies to achieve energy efficiency and a reduction in CO₂.

This project is one of several provided by AVIC to Chinese cement producers using KHD’s pyroprocessing, grinding, alternative fuel and digitalisation solutions.
