Qatar: Al Khalij Cement Company (AKCC) has signed a memorandum of understanding with Qatar’s Public Works Authority (Ashghal) to recycle 100% of the sludge generated by the country’s wastewater treatment plants into alternative fuel for cement production. The five-year agreement aims to convert between 744,000t and 1.29Mt of sludge into alternative fuel. According to Mohammed bin Abdulaziz Al Meer, president of Ashghal, treated water will be reused for irrigation and cooling, while solid byproducts like sludge will be used as fuel catalysts and inputs in cement manufacturing. The use of the sludge-derived fuel will reportedly reduce natural gas consumption and lower greenhouse gas emissions. AKCC said that the use of alternative fuels under the agreement will reduce CO₂ emissions by around 40,000t.

Spain/Mexico: Waste to Energy Advanced Solutions (WtEnergy), in collaboration with Cemex Ventures, has received the support a €4.4m EU Innovation Fund grant that aims to develop its advanced waste-to-fuel conversion technology. The companies say that the financial backing highlights the potential of the solution as a clean and scalable energy alternative for the cement industry.

WtEnergy’s technology upgrades waste into low-CO₂ syngas, clean hydrogen and other bioproducts. It will help to accelerate the integration of clean energy sources into Cemex’s global clinker and cement manufacturing operations.

WtEnergy has separately received funding under the EU Horizon Europe HYIELD Project, which was recently awarded a €10m grant by Horizon Europe to develop hydrogen fuels at Cemex’s Alcanar cement plant in Spain.

India: The Ahmedabad Bench of the National Company Law Tribunal (NCLT) has cleared the proposed merger of Sanghi Industries Limited with Ambuja Cements Limited, a crucial step in Adani Group's rapid consolidation of its cement business. The appointed date for the merger is 1 April 2026. The scheme will become effective once all procedural formalities are completed and statutory filings are made.

With the merger now approved, Sanghi Cement's assets, liabilities and authorised capital will be fully absorbed into Ambuja Cements. The company stated that the consolidation will enable better resource utilisation, cost efficiencies, elimination of overlapping functions, and improved shareholder value.

Ambuja Cements acquired a controlling 56.74% stake in Sanghi Industries in August 2023, marking Adani's first major deal in the cement sector after acquiring Ambuja and ACC in 2022. The Sanghi buyout was aimed at strengthening the group's manufacturing footprint in western India, especially Gujarat, and securing access to Sanghi's valuable limestone reserves and port infrastructure.

India: JK Lakshmi Cement has introduced Green Pro LC3, one of India’s first commercially-available limestone calcined clay cement (LC3) products, which it says marks a key step towards expanding its low-carbon construction materials portfolio.

The company will produce the LC3 cement at its integrated Jaykaypuram plant in Sirohi, Rajasthan. Commercial dispatches are scheduled to begin in February 2026, with the initial rollout focused on institutional and project-led demand across northern and western India.

According to JK Lakshmi Cement, Green Pro LC3 enables a 40% reduction in CO₂ emissions compared with ordinary Portland cement. The cement has been developed to improve durability, reduce permeability and enhance performance in large-scale and high-exposure construction applications. The LC3 formulation combines clinker, calcined clay, limestone and gypsum. The company said this composition offers higher resistance to chloride ingress and sulphate attack, lower heat of hydration and improved lifecycle performance, particularly in marine, coastal and high-temperature environments.
