Canada: Heidelberg Materials North America’s Edmonton cement plant in Alberta now co-processes 50% alternative fuels (AF) following an upgrade. Heidelberg Materials North America installed equipment and infrastructure for AF co-processing with the help of a US$1.71m grant from the Alberta Technology Innovation and Emissions Reduction fund.

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."

France: Fives FCB has partnered with Holcim to decarbonise its cement production processes. Fives conducted successful hydrogen tests at the La Malle site in France, achieving over 50% hydrogen substitution in cement production. This result also enabled a significant increase in the use of alternative fuels while still maintaining cement quality. The group has also developed a digital model to tailor this process to each cement plant's unique requirements.

Spain: Cemex España plans to install a new tertiary mill in its Alicante cement plant’s refuse-derived fuel (RDF) line. The project, called Molentis, is scheduled for completion in early 2025 and will cost €6m. The Molentis upgrade will help the Alicante cement plant to raise its RDF substitution rate by 8%, according to the producer. This in turn will reduce its CO₂ emissions by 6700t/yr. The Spanish Ministry of Industry, Energy and Tourism granted €4.4m toward the project to Cemex España under its Innovation and Sustainability Plan.

Cemex España director of operations Benjamín Cabrera said "Molentis will enable us to advance towards climate neutrality and position the Alicante factory at the forefront of new technologies in the decarbonised industry."

Philippines: Cemex Philippines processed 700,000t of waste into alternative fuel (AF) for its Apo and Solid cement plants in 2023. Malaya Business Insight News has reported that the volume equates to three months’ waste generation for the entire city of Manila. Cemex Philippines recorded an AF substitution rate of 30% for the year.

President and CEO Luis Franco said “Cemex Philippines is proud to be a leader in circular economy. We believe that in transforming waste into value, we can create a positive impact on the environment, the society, and the economy. We are committed to continue innovating and collaborating with our stakeholders to address the country’s waste problems.”

France: Vicat aims to process 100% alternative fuels (AF) in its fuel mix across all cement plants in France by 2025. The L'Est Républicain newspaper has reported that the producer recorded a substitution rate of 66% in France in 2022, and of 95% at its Xeuilley cement plant in Meurthe-et-Moselle in the same year.

Philippines: Holcim Philippines recorded sales of US$332m during the first nine months of 2023. This represents a 4% drop from nine-month 2022 levels. The producer reported operating earnings before interest and taxation (EBIT) of US$25.2m. Throughout the period, Holcim Philippines co-processed 800,000t of alternative fuel (AF) at its plants. Blended cement products ended September 2023 at 75% of its cement sales.

France: Lafarge France has ignited the new kiln at its Martres-Tolosane cement plant following a Euro120m upgrade. Local press has reported that the upgrade replaced the plant’s existing kilns and preheater tower with entirely new equipment. The new kiln has tripled the plant’s capacity, to 2.1Mt/yr from 0.7Mt/yr. Meanwhile, the new preheater tower will help to reduce the plant’s electricity consumption by over 20%. As a result of the upgrade, the Martres-Tolosane plant can now support an alternative fuels (AF) substitution rate of 60%, compared to 20% beforehand. Lafarge France aims to carry out further work to reach 85% AF substitution at the plant by 2027. Other planned projects include the installation of a carbon capture system.

Lafarge France CEO François Petry said “We are going to create a research and innovation centre here dedicated to the capture of CO₂, with the ambition of ultimately making the Martres-Tolosane plant net zero carbon.”

Spain: Holcim España invested Euro4m in an upgrade to its 1.5Mt/yr Carboneras cement plant in Almería. Alimarket-Construction News has reported that the upgrade will raise the plant’s alternative fuel (AF) substitution rate to 70% and enable it to dispose of 50,000t/yr of waste through co-processing it as AF. Holcim España expects this to reduce its CO₂ emissions by 22,000t/yr.

Nigeria: Dangote Cement plans to raise its alternative fuel (AF) substitution rate across its Nigerian operations to 25%. The Punch newspaper has reported that the producer consumed 34,800t of AF during the first half of 2023.

Obajana cement plant head of sustainability Eseosa Ighile said “We are working towards installing AF feeding systems in all our operation lines by 2024.”
