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."

Philippines: Holcim Philippines and Universal Robina Corporation (URC) have entered a tripartite agreement with the local government of Obando, Bulacan, to provide incentives for workers at the town's material recovery facility, based on the volume of refuse diverted. The material recovery facility in Obando has collected and sorted 785t of plastic waste for co-processing. Since 2021, URC and Holcim's waste management unit Geocycle has been processing plastic from URC's operations for co-processing. The plastics are converted into alternative fuels used to power the kiln at Holcim’s plant in Misamis Oriental.

Irwin Lee, URC president and CEO, said "This new agreement, with Obando as a key partner, aims to further drive community-based ‘waste’ diversion efforts. We hope to replicate it in other towns and cities to amplify the impact of what we set out to do three years ago."

Indonesia: Indocement Tunggal Prakarsa has acquired a 20% stake in Amita Prakarsa Hijau, a company that specialises in the recycling of industrial and municipal refuse and biomass-derived materials into alternative fuel for the cement industry. The deal is valued at US$120,000 and was completed on 8 October 2024.

Canada: Lafarge Canada, a subsidiary of Holcim, has inaugurated a new low-carbon fuel facility at its Exshaw cement plant, in a joint effort with Geocycle Canada. The US$28m facility is supported by a US$7.4m contribution from Emissions Reduction Alberta through the government’s Technology Innovation and Emissions Reduction fund. It will reduce natural gas consumption by up to 50% for one of the plant’s kilns by substituting it with alternative fuels (AF) sourced from construction and demolition materials, primarily wood. Geocycle will process the materials into AF. This initiative is expected to divert up to 120,000t/yr of discarded materials from landfill, reducing CO₂ emissions by approximately 30,000t/yr.

President and CEO of Lafarge Canada (West), Brad Kohl, said "Our commitment to building a sustainable future is at the core of everything we do. The low-carbon fuel project is a prime example of how innovation and collaboration can drive positive change, lowering our environmental footprint through the use of discarded biomass materials while closing the material loop to conserve natural resources.”

Egypt: Cemex Egypt has inaugurated new decarbonisation equipment at the Assiut cement plant, aligning with its ‘Future in Action’ sustainability strategy. The technology repurposes residual material into energy, incorporating high-efficiency separators and improvements to the calciner process, reducing CO₂ emissions by approximately 32kg/t of cement produced, totalling a reduction of 290,000t/yr.

President of Cemex Egypt & UAE, Yago Castro, said “The inauguration of the decarbonisation equipment at the Assiut plant is a testament to our ongoing efforts to create a more sustainable future for our communities and the planet. At Cemex, we are committed to leading climate action in the industry, using the highest alternative fuels substitution rate in the cement industry in Egypt.”
