Greece: Titan Group has successfully commissioned an upgrade to the pre-calciner system of its Kamari cement plant in Voiotia. Titan Group says that this will enable the 3.1Mt/yr plant to expand its range of lower carbon cements, reducing its CO₂ emissions by 150,000t/yr. It also increases the plant's maximum possible alternative fuels (AF) substitution rate.

Titan Group’s Europe regional executive director Yanni Paniaras said "The completion of the Kamari plant upgrade represents a significant achievement for Titan Group. We are witnessing tangible results as our green innovation gains momentum and takes shape. This successful implementation of one of our major capital expenditure projects exemplifies our dedication to sustainable operations and strategic growth, while we continue to pursue more growth opportunities in all our active markets. We are committed to offering our customers and communities greener products and solutions, playing our part in building a sustainable future for all.”

France: Ciments Calcia has announced an investment of Euro86m to further decarbonise cement production at its integrated Beaucaire plant. The subsidiary of Germany-based Heidelberg Materials has allocated a total of Euro600m towards reducing CO₂ emissions from all of its operations in the country in response to a government initiative, according to The Tribune newspaper.

The current funding follows a spend of just under Euro7m on upgrades at the site, including installing a new clinker cooler that will allow for greater recovery of waste heat, and the addition of a new computer control system. Following this work, the single production line plant was restarted in early April 2023.

The next stage of investment has started with a feasibility study. If successful, a tendering process could start in the second half of 2023 with work planned to start in 2025. The company intends to renovate the plant’s electricity network, modernise the production line with a preheater and a pre-crusher and make further changes to target an alternative fuels thermal substitution rate of 75%. A third stage, involving carbon capture and utilisation and/or storage, is tentatively planned to start in 2030.

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.”

Saudi Arabia: Yamama Cement has commissioned its second cement plant, with 20,000t/day in capacity across two clinker lines. The producer invested US$1.25bn in the plant's construction, which was carried out by Germany-based ThyssenKrupp. The facility is equipped with seven raw materials crushers, a 3.7km-long limestone conveyor belt, 110,000t of storage capacity, four Quadropol roller mills, two Dopol preheater towers, two Polro rotary kilns, two Polytrack clinker coolers, three 100,000t clinker silos, four Polycom high-pressure roller mills, six 22,590t and 25,000t cement silos and 22,000m³
in water storage basins. The new plant is situated in the eastern Arabian Desert, 80km from Riyadh.

Yamama Cement also operates the 6.4Mt/yr Al Karj Cement plant, 70km from Riyadh.

France: Heidelberg Materials' subsidiary Ciments Calcia has laid the foundation stone for its construction of a Euro285m CO₂ emissions-reducing upgrade to its Airvault cement plant in Nouvelle-Aquitaine. Ciments Calcia first published its plans for the installation of a new 4000t/day production line to replace both existing lines at the Airvault plant in 2021, with commissioning scheduled for mid-2024.

Germany-based ThyssenKrupp secured the order to supply a 1200t/hr double-shaft hammer crusher, a longitudinal blending bed, a 370t/hr Quadropol QMR² 45/23 vertical roller mill, a 10,000t raw materials tangential blending silo, a single-string, five-stage Dopol cyclone preheater with integral calciner for alternative fuels (with the possibility of conversion to oxyfuel), a Polytrack clinker cooler, a solid recovered fuel preparation line and dedusting systems for the 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."

Asia: FLSmidth says that it has won a contract to supply its low-NO_x ILC preheater, an OK raw mill, an OK cement mill and other equipment to a cement plant in Asia. FLSmidth will deliver the equipment in 2023. The total value of the deal is US$56.1m.

FLSmidth’s cement industry president Carsten Riisberg Lund said "This project showcases FLSmidth’s ability to deliver energy efficient technologies across the full cement flowsheet, and thereby support our customers in both increasing capacity and their sustainability efforts.”

Greece: Titan Cement Group has secured an EU patent for its robotic remote preheater system, previously installed at the company’s Kamari cement plant in Viotia. Titan Cement Group designed the system to maximise operational efficiency and safety.

The company carried out a Euro25m precalciner installation at the Kamari plant in 2021 – 2022.

Mexico: GCC has signed an engineering, procurement and construction (EPC) contract with ThyssenKrupp Polysius for an upgrade to its integrated Samalayuca plant to increase clinker production capacity, raise the usage of alternative fuels and reduce emissions. The project includes the engineering, supply and modification of the preheater, including cyclones, and an extension to the calciner, with the installation of a Prepol SC-S type system to increase the utilisation of alternative fuels. The work also includes fitting a Polytrack type clinker cooler and the installation of a bypass system. The project will begin in 2022 with operations scheduled to start in the second quarter of 2023.

Senegal: France-based Fives has detailed the equipment that it will supply for its construction of a new 6500t/day kiln line at SOCOCIM Industries’ Rufisque cement plant in Dakar Region. The company says that it will supply a preheater, in-line Preca calciner, kiln, TGT filter and Pillard Novaflam burner.

SOCOCIM Industries’ parent company Vicat’s chair and chief executive officer Guy Sidos said “Vicat Group renews its partnership with Fives Group through this major project of building a new line with a strong local dimension, employing local workers and contractors.” He added “This plant will eventually eliminate the use of fossil fuels, reduce our energy consumption and support Senegalese local development, making a higher quality product while doubling our production capacity.”
