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.”

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.

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.”

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.

Portugal: Cimpor Portugal has signed a contract with Germany-based KHD Humboldt Wedag (KHD) for an upgrade to production line 7 at its Alhandra cement plant. The project is intended to increase the production capacity at the plant to 3600t/day from 3000t/day and increase the line’s alternative fuels thermal substitution rate to over 80%. It will also be the first installation of KHD’s Pyrorotor alternative fuel combustion reactor in the country.

The scope of the engineering and supply contract comprises:

• New HKSK 224/335 preheater ID fan
• New downcomer duct
• New preheater with 8064/5-type HEM cyclones
• Pyroclon R calciner with Pyrotop mixing chamber. The Pyroclon R will utilize fine refuse-derived fuel (RDF) and natural gas
• 4m x 10m Pyrorotor alternative fuel combustion reactor
• Pyrobox coal firing system for process start-up and operation balancing
• Shortening of the existing kiln and installation of new kiln inlet chamber with bypass extraction
• New kiln drive station 2 (the existing girth gear and two pinions will be reused)
• New kiln hood and take-off of tertiary air from the cooler roof
• New main kiln burner designed to use more than 50% alternative fuels (but will also be capable of burning natural gas, as well as liquid fossil and alternative fuels)
• New Pyrofloor PFC²829AW cooler with a Pyrocrusher PRC 420-3ES clinker crusher.

KHD will also be supplying its KHD ProMax software product as part of the project.

Matthias Mersmann, chief technology officer at KHD, said “The decision by Cimpor Portugal to opt for KHD pyroprocessing equipment - and especially the Pyrorotor - underlines the leading market position of KHD, as well as the outstanding capability of KHD’s unique alternative fuel-processing solution.”

Project execution will be led by KHD Germany, with support from Humboldt Wedag India and the Turkish branch office of Humboldt Wedag. Commissioning of the upgraded production line is scheduled for 2025.

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."

India: Nuvoco Vistas has commissioned feeding systems for alternative fuel (AF) in the pyro-process sections of its Nimbol and Risda cement plants. The systems will handle municipal solid waste, including unrecyclable plastic.

Managing director Jayakumar Krishnaswamy said "As part of our Protect Our Planet agenda, we view the AF projects as an important step towards fulfilling our commitment to sustainable cement manufacturing and reducing the environmental impacts. The successful completion of this project demonstrates our commitment to reducing carbon emissions, maximising waste consumption and demonstrating responsible resource management practices.” He added "This along with, other themes under Protect Our Planet agenda, is enabling Nuvoco to build robust partnerships with several stakeholders, and contribute to society at large.”

US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NOx emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.

David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.

Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”

The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.

Lithuania: Arturas Zaremba, the head of Akmenes Cementas, has warned that government proposals to increase the import tax on coal in 2024 and the abolition of subsidies for the fuel will affect the company. The country’s parliament is also proposing scaling the import tax based on a CO2 scale, according to the Baltic Business Daily newspaper. Zaremba said that the cement producer uses 130,000t/yr of coal. However, it is currently investing Euro22m on an upgrade to its Akmenes integrated plant to allow it to switch to using a higher proportion of solid-recovered fuel. It currently has a 10% alternative fuels substitution rate using dried sewage sludge and tyres.

Zaremba said "There will be some impact because we will still have some of that coal left, but not as much as we would have had without the investment. I have not followed how much they plan to increase the excise duty, but we need to look into how much that would be in the financial terms. Any increase has an impact."

Chile: Cbb Cementos and Ambipar Environment have announced an upgrade to the Curicó plant that will allow it to process refuse-derived fuel (RDF). The US$5m investment will allow the unit to process around 36,000t/yr of RDF. The work will include building a reception hopper, a screening system, a belt feed belt to the calciner and a dosing system. Three warehouses will also be constructed. The alternative fuels upgrade is expected to start operation in early 2024.
