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."

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.”

US: Summit Materials has entered into a memorandum of understanding (MOU) with hydrogen producer PCC Hydrogen (PCCH2). The MOU establishes an alliance to develop a fuel replacement strategy for Summit Materials’ cement production. PCCH2 will build a hydrogen plant to supply green hydrogen at a cement plant belonging to Summit Materials subsidiary Continental Cement.

Continental Cement president David Loomes said "Continental Cement has a longstanding commitment to environmental stewardship, seeking out opportunities to develop innovative practices and differentiated solutions to build a better tomorrow. Our company has signed on to the Portland Cement Association (PCA)'s Roadmap to Carbon Neutrality, with a goal of achieving carbon neutrality across the value chain by 2050. By coupling PCCH2's hydrogen production process with our cement manufacturing know-how, we are taking a bold stride towards achieving that goal, while continuing the push to cost-effective decarbonisation of cement manufacturing."

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.

Bulgaria: Titan Cement subsidiary Zlatna Panega Cement plans to invest Euro11m in sustainability-enhancing upgrades to its Zlatnopanegki cement plant in Lovech Province. The work centres around a Euro7m alternative fuels (AF) upgrade, to raise the plant’s AF substitution rate to 70% from 50% in 2022. Besides this, the producer will also invest Euro4m in the construction of a solar power plant at the facility. The solar power plant is scheduled for commissioning in March 2024. General manager Adamantios Frantzis said that the plant will subsequently move on to its ‘next big project,’ consisting of a Euro35 – 50m upgrade, in 2026 – 2028.

Zlatna Panega Cement invested Euro5.7m in capital expenditure throughout 2022, more than double its investments of Euro2.6m in 2021. It is committed to interim CO₂ reduction targets of 5000t/yr (Scope 1) and 3000t/yr (Scope 2 and 3), and net zero CO₂ emissions by 2050.

Mexico: Cemex Mexico’s Puebla cement plant directly prevented 55,300t-worth of CO₂ emissions through alternative fuel (AF) substitution during the first eight months of 2023. RSS News has reported the facility recorded the highest alternative fuel (AF) substitution rate anywhere in Latin America. When factoring in its removal of landfill-associated CO₂ emissions, this gives the Puebla plant’s cement a carbon footprint of 400kg/t. Cemex is committed to reducing its specific emissions to 430kg/t of cement globally by 2030.

Brazil: Votorantim Cimentos has secured a US$150m loan from the International Finance Corporation for an upgrade to its Salto de Pirapora cement plant in São Paulo. The producer aims to increase the alternative fuel (AF) substitution rate at the 4.8Mt/yr plant, and reduce its CO₂ emissions. It says that the loan is tied to sustainability performance indicators (SPIs), based on the reduction in the plant’s Scope 1 CO₂ emissions.

Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO₂ emissions by 400,000t per decade.

Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO₂ company."

Egypt: Heidelberg Materials subsidiary Suez Cement has invested US$16m in upgrading its operations towards increased alternative fuel (AF) use since 2010. The producer uses AF in the burners and kilns of all three of its cement plants, at Helwan, Kattameya and Suez. Meanwhile, Suez Cement has invested US$60m in dust control measures over the same period. Other on-going investments include US$25m in the construction of a waste heat recovery (WHR) plant at the Helwan cement plant. The company is committed to reaching a 24% reduction in its CO₂ emissions between 2019 and 2030.

Technical director Omar Khorshid said “We are committed to pursue initiatives to broaden our range of innovative and eco-friendly building solutions, advance operational efficiency through digitalisation and strengthen customer engagement for better business results and more positive impact."

Argentina: Geocycle has commissioned the new Line 2 of its Piedra Blanca waste management plant, Norte En Linea News has reported. The facility will now process 100,000t/yr of waste. Geocycle will supply the remaining 45% fraction of unsorted waste after processing to Holcim Argentina's Malagueño cement plant for use as refuse-derived fuel (RDF). By diverting non-recyclable waste from incineration, Geocycle says that the new line will eliminate 25,000t/yr of CO₂ emissions.
