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.

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.

Pakistan: Attock Cement expects that its cement despatches will decline by 10% year-on-year in the 2025 financial year. During a corporate briefing it revealed that local despatches of cement had fallen by 20% year-on-year to 7.91Mt in the first quarter to 30 September 2024 from 9.87Mt in the same period in 2023, according to the Pakistan Press International news agency. The decrease was more pronounced in the south of the country than the north. Despite this, exports grew by 22% to 2.14Mt. The company’s turnover and profit also fell during the reporting period.

The company is currently investing US$4.5m in a 4.8MW wind power unit. The project is intended to reduce the company’s reliance on the local electricity grid and reduce power costs generally. It is expected to become operational from January 2025. The cement producer is also planning to increase its usage of alternative fuels to further bring down production costs.

UK: Cemex UK has announced that it will begin to use hydrogen on an industrial scale at its Rugby cement plant in Warwickshire. It will do so via HiiROC, a UK-based start-up that has received backing from Cemex Ventures. HiiROC produces carbon-neutral hydrogen using its proprietary Thermal Plasma Electrolysis (TPE) process, which requires just 20% of the electrical energy used in water electrolysis and captures carbon as a solid byproduct, avoiding CO₂ emissions. HiiROC’s modular solution can be deployed as single units to full-scale industrial plants. The hydrogen produced can be used as an alternative energy source to fuel clinker production processes, helping Cemex to achieve its decarbonisation goals.

"Our investment in this innovative project alongside HiiROC reinforces Cemex's commitment to transform the industry by working hand in hand with disruptive startups and new technologies," said Gonzalo Galindo, the head of Cemex Ventures. "Hydrogen as an alternative energy source has the ability to significantly reduce CO₂ emissions in our operations, aligning with our 2050 goal of becoming a net-zero CO₂ company and a leader in the industrial use of hydrogen."

Brazil: Votorantim Cimentos has reported that its net profit surged by 24% in the third quarter of 2024 compared to the same period of 2024, to reach US$179m. Its net revenue increased by 6% year-on-year to reach US$1.33bn.

However, when excluding currency fluctuations, revenue decreased by 1%. This highlights the significant impact of foreign exchange rates on Votorantim's global operations. Adjusted earnings before interest, tax, depreciation and amortisation (EBITDA) rose by 20% to US386m. Cement sales volume increased by 3% to 10Mt during the quarter.

The company said that these figures indicate resilient demand across Votorantim's markets, despite challenging economic conditions in some regions. The company's diversified geographical presence has helped balance market fluctuations.

In the sustainability arena, Votorantim Cimentos also says that it has made significant progress. The company reduced its specific embodied CO₂ emissions by 4% to 556kg/t of cement in 2023. It has also increased its alternative fuel thermal substitution rate (TSR) from 26.5% in 2022 to 30.9% in 2023.

Kenya: East African Portland Cement (EAPC) has contracted a technical audit from Denmark-based FLSmidth Cement with a value of just under US$70m. EAPC’s acting managing director Mohamed Osman said the findings would guide a pending plant upgrade, to be funded by some of the proceeds from the land sale, according to the Star newspaper. It hopes to double capacity at the unit by the late 2020s without incurring debt. The cement producer is also considering its options to use alternative fuels such as macadamia husks and other agricultural biomass. The 10-week audit process is expected to end in early December 2024.

Osman said “We have tapped FLSmidth to undertake a comprehensive technical audit of the plant, which will assess how to maximise the capacity and inform the design and cost of a new one,'' Osman said. “The audit by FLSmidth will also look at the reserves of raw materials that it has and inform whether it needs to acquire more land that has adequate reserves.”

Nigeria: Lafarge Africa has launched a new alternative fuel and raw material (AFR) platform at its Mfamosing cement plant in Cross River State, with the aim to reduce its CO₂ emissions. The facility will replace traditional fossil fuels with alternative energy sources derived from non-recyclable materials, according to the Nigerian Tribune.

Türkiye: Limak Çimento has carried out a month-long test on hydrogen fuel blends at its cement plant in Ankara. The company partnered with France-based Air Liquide for the supply of hydrogen, which was injected into the preheater tower. The pair previously used a 50% hydrogen blend during a test at Limak’s Polatli plant in June 2024, with ‘excellent results’, according to Hydrogen Insight.

Erkam Kocakerim, CEO of Limak Çimento, said "The purpose of this investment is to enable safe and effective use of hydrogen technologies in our cement kilns and to increase the rate of alternative fuel substitution. We aim to operate the kilns in our seven integrated cement plants with a low-carbon fuel mix between 2030 and 2035."

Oman: Raysut Cement Company has launched a programme to recycle industrial byproducts for use as alternative fuel in cement production and electricity generation, to align with Oman's goal of net zero emissions by 2050.

Hilal bin Saif Al-Dhamri, Acting CEO of Raysut Cement, said "We use secondary industrial materials resulting from production processes across various industries. These are recycled in cement manufacturing and are categorised into two types: one that can be reused as an alternative fuel in plants, the other is used as a partial replacement to the main raw materials leveraged for cement production.” He added "We implemented a project to reuse exhaust heat and convert it to electrical energy at the Raysut Cement plant in Salalah. This innovative approach permits the plant to generate approximately 30% of its electrical energy, by reducing around 50,000t/yr of CO₂. As a result, the Salalah Raysut Cement plant stands out as environmentally friendly, distinguished by its capability to provide clean energy for cement production."

Al-Dhamri also noted that the company was able to enhance the efficiency of its Salalah plant through this programme, by reducing the clinker content while improving the performance of cement in concrete. This has reportedly contributed to a CO₂ emissions reduction of around 18% compared to ordinary cement.

UK: Alternative fuel manufacturer WKE has expanded its product range with new pellet sizes, including 9mm and 6mm shortcut pellets for extended burn times and reduced leftover material in cement kilns, and a 16mm pellet for the biomass sector. This development aims to address specific industry challenges and meet growing demand in both UK and international markets.

CEO Ian Jones said "Our new range of pellet sizes represent a significant step forward in our mission to provide a cleaner, greener and cost-effective alternative to fossil fuels. By tailoring our products to meet the bespoke needs of sectors like cement, we can further support these heavy energy-use industries in reducing their dependence on fossil fuels, all while cutting their energy costs and tackling the enormous amount of material that ends up in landfill."
