Cemex uses 37% alternative fuel globally in 2023
25 March 2024Mexico: Cemex said in its Integrated Report 2023 that its alternative fuel (AF) substitution rate rose to 37% in 2023. The group attributed the rise to its deployment of hydrogen injection technology.
Cemex said “We continued our global roll-out of hydrogen injection technology, and it's now used in half of our cement plants. In Mexico alone, we made sizeable investments installing new hydrogen units and plan to continue scaling hydrogen use in our operations worldwide.”
ACC and Ambuja Cements' Geoclean launch new facilities
20 March 2024India: ACC and Ambuja Cements' Geoclean has launched two new facilities for sustainable waste management. The Ambuja Marwar pre-processing and co-processing facility in Rajasthan can convert 220,000t/yr of refuse into alternative fuel, while the ACC Jamul co-processing facility will process an additional 120,000t/yr.
The Ambuja Marwar facility, in collaboration with the Ambuja Marwar Farmer Producer Organisation, aims to source 50,000t/yr of agricultural waste from local farmers. This initiative will also increase the plant's thermal substitution rate to 15%. Similarly, the ACC Jamul facility will enhance its thermal substitution rate to 10%, reducing CO₂ emissions through the co-processing of waste in the cement kiln.
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."
Vicat targets 100% alternative fuel substitution in France by 2025
04 December 2023France: 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.
European Union eases up on sustainable packaging
23 November 2023Europe: The European Parliament voted in favour of multiple amendments to the European Commission’s Packaging and Packaging Waste Regulation (PPWR) on 22 November 2023. The amendments remove, modify or make non-binding the PPWR’s 2040 reuse targets. Meanwhile, 2030 targets were made adjustable to recycling rates. Total packaging volumes are still required to drop by 5% by 2030 and by 15% by 2040 in each member state.
Sustainability lobbying organisation Environmental Coalition on Standards (ECOS) described the introduction of recycling rates into a lower schema of waste targets as ‘comparing apples with pears.’ ECOS attributed the amendments to a ‘barrage’ of false claims, scaremongering and lobbying from industry players.
ECOS programme manager Mathias Falkenberg said “This decision will not sufficiently address rising plastic and packaging waste or the pollution crisis. The European Parliament has just weakened a perfectly feasible solution to tackle throwaway culture without offering an alternative. It is very frustrating that the European Commission’s progressive prevention and reuse agenda has not received full support from the Parliament today.”
ECOS founded the Alliance for Low-Carbon Cement & Concrete (ALCCC), an association of companies focused on alternative building materials production, in May 2023.
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."
Cemex Mexico’s Puebla cement plant sets Latin American eight-month AF substitution record
02 October 2023Mexico: 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.
Dangote Cement to raise alternative fuel substitution rate to 25%
13 September 2023Nigeria: 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.”
India: Heidelberg Materials subsidiary Zuari Cement has commissioned a 20t/hr alternative fuel (AF) production line at its 7.1Mt/yr Yerraguntla cement plant. The line includes an UNTHA XR3000C shredder. This will support continuous operations and turn waste to AF in a single step, according to Zuari Cement.
HeidelbergCement India technical director Vimal Jain said “We are passionate about driving environmental progress throughout our business, and the use of AF is one way to do that. But this waste-to-energy feedstock comes at a cost, which is why co-processing makes so much sense. When designing this plant, we needed to ensure versatility to allow for changing market conditions, and an investment in technology that makes commercial sense and is built to last.”
