Germany: Canada-based company Rock Tech has promoted a peer-reviewed study by the German Lithium Institute that confirms the potential of byproducts from lithium production to be used in cement manufacture. The study found that leached spodumene concentrate (LSC), primarily composed of aluminosilicates, can replace fly ash as an additive in the cement industry. The study also revealed that adding 20% LSC to Portland cement increases its compressive strength by 10%. The process for producing and utilising LSC has been submitted for a patent.

"The phase-out of coal and the transformation of the steel industry will sooner or later lead to changed or disappearing material streams that have been significant for the cement industry in terms of CO₂ savings and product portfolio. The LSC from lithium production has the potential to compensate for these depleting material streams in the future."

Chad: The Group Cement of Africa (CIMAF) plans to raise the production capacity of its Chad cement plant from 0.5Mt/yr to 0.7Mt/yr. Anas Sefrioui, President of CIMAF, conveyed this intention to Chad's President Mahamat Idriss Deby Itno, with the intention to meet market demands, reduce costs and create jobs. Sefrioui also announced that the official price of cement bags from the plant will be revised to alleviate public costs. The CIMAF cement plant in Lamadji, north of N'Djamena, commenced operations in June 2017.

Cameroon: Cimpor has inaugurated its new plant in Kribi, Cameroon. Following investments in Côte d'Ivoire, Cimpor embarked on this greenfield project in February 2020, integrating the ‘world's first’ operational flash calcined clay production line, launched on 29 October 2023.

Cimpor Cameroun now has an output of 1.2Mt/yr of cement and 0.4Mt/yr of calcined clay. Cimpor's calcined clay production technology - ‘deOHclay’ – reportedly saves up to 80% in CO₂ emissions, up to 35% in electricity consumption and up to 40% in thermal energy consumption per tonne. Compared to a plant with a similar capacity, this technology could reduce CO₂ emissions by around 0.2Mt/yr, according to the company. The new plant will reduce the country’s dependence on imports to meet local cement needs.

India: UltraTech Cement reported a flat net profit for the three month period ending 30 June 2024 of US$203m, compared to US$202m in the same period in 2023. The company's income rose by 2% to US$2.18bn, while domestic sales volumes grew 7% year-on-year to 32Mt, despite a 9% decline from the previous quarter. EBITDA slightly declined to US$383m from US$384m.
