US: National Cement is upgrading its Lebec cement plant in California to make it carbon neutral. The upgrade involves a transition to limestone calcined clay cement (LC3) production. The producer will also substitute fossil fuels with locally-sourced biomass, including pistachio shells, in cement production. Lastly, a carbon capture installation will remove 950,000t/yr of CO₂ from the plant’s flue gases.

Ethiopia: East Africa Holding (EAH) has set up a subsidiary, Pan Afric Energy, to pilot using the prosopis juliflora shrub as a biomass alternative fuel at its integrated Dire Dewa plant operated by its National Cement subsidiary. The US$50m project testing using the invasive species is backed for a number of different partners, including the local government and the European Union, according to the Capital newspaper. So far the initiative has reached a 5% thermal substitution rate at the Dire Dewa plant. The project is also considering using the shrub as an alternative fuel at a new cement plant being built at Lemi town, in the North Shoa zone of Amhara region. EAH has formed a joint-venture with China-based West China International Holding to build the new plant.

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."

US: Vicat subsidiary National Cement Company of Alabama inaugurated its new US$300m production line at its Ragland cement plant on 21 July 2022. Local press has reported that the line includes a new rotary kiln, equipped for alternative fuel (AF) use.

President Spencer Weitman said “This puts us into the next 40 or 50 years. And it’s prolonged the life of the plant to move us forward into the next entry hopefully.”

Egypt: Chemical Industries Holding, a industrial chemical manufacturer, has formed a committee for a consultancy to study offering a mixture of coal and alternative fuels for National Cement. The committee will also consider the financial and technical aspects of supplying a cement mill for the cement producer.
