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.”

Brazil: Secil Supremo Cimentos has appointed FLSmidth to carry out a pyro process upgrade at its Adrianópolis cement plant in Paraná. The Denmark-based supplier says that it plans to carry out modifications on the plant's preheater, cooler and related auxiliary equipment. It says the new equipment will expand the plant's capacity to 3900t/day, corresponding to an annual production capacity of 1.42Mt/yr. It will also enable it to increase its alternative fuel (AF) substitution rate to 40%. Secil Supremo Cimentos' AF mix consists of shredded tyres, wood and other refuse-derived fuels.

FLSmidth's head of capital sales, Jens Jonas Skov Larsen, said “We are grateful for our continued partnership with Supremo, which has consistently invested in the latest technology. As the plant was already operating an ILC five-stage preheater from FLSmidth, it was well positioned to use AF.”

South Korea: ThyssenKrupp Polysius’ Asia Pacific division has won an order to supply a Prepol SC type step combustion chamber for an unnamed cement plant in South Korea. The scope of the contract includes engineering, mechanical equipment and some modifications to the preheater tower. The commissioning of the system is planned for the end of 2023.

Regional chief executive officer Lukas Schoeneck said “The current turbulence on the coal market create a lot of pressure in cement plants to significantly increase the efforts on alternative fuels. Especially when talking high thermal substitution rates and lower quality alternative fuels, combustion chamber technologies connected to the calciner – like the Prepol SC - are the most suitable solution in the cement industry. Congratulations to the colleagues in Germany and in Asia working on this project.”

US: National Cement Company of Alabama has reported that the new kiln line at its Ragland cement plant will reduce the plant’s CO₂ emissions by 40%. Its energy consumption will also fall by 30% as a result of the upgrade. The new line includes a 78m-high homogenisation silo, vertical crusher, five-stage preheater and automated clay storage system. AF used in the kiln will include waste tyres, woodchip and sawdust. The new kiln will help in the Ragland cement plant’s transition to 100% Portland limestone cement (PLC) production by 2023, further diminishing its carbon footprint.

Vicat CEO Guy Sidos said "Our ambition is to use AF in all our cement plants around the world. In addition to eliminating fossil fuel energy and replacing it with recycled regional waste, our investments contribute directly to local development. We are proud of the modernisation and transformation of our Ragland site, which was our very first acquisition outside France in 1974."
