India: Adani Group will invest US$603m in the construction of a 4Mt/yr clinker plant at Chorgadi and grinding plants in Dewas and Bhopal. The combined capacity will be 8Mt/yr. The move is part of a US$9bn investment which the company says will create 15,000 jobs across various sectors.

Germany: Australia-based Calix confirmed that its LEILAC-2 project will take place at Heidelberg Materials’ cement plant in Ennigerloh, Germany. This follows Heidelberg Materials' decision to cease clinker production at its Hanover cement plant. The project, which aims to capture CO₂ emissions from cement production, already has a system design ready for construction at Ennigerloh.

LEILAC CEO Daniel Rennie said "The LEILAC technology represents a scalable and economical solution to address the carbon dioxide emissions produced unavoidably by the cement and lime industries, and the rapid demonstration of such solutions is essential to achieving our industrial decarbonisation goals."

Saudi Arabia: Kreisel has delivered three 700 x 700mm high-pressure rotary valves to a China-based engineering firm for its construction of a cement plant in Saudi Arabia. Each valve is equipped with Ultra-Carbide protection and is able to convey 125t/hr of raw meal over a distance of 263m. In addition to the valves, Kreisel will also supply air supply units and other non-critical components.

Germany: Heidelberg Materials has secured a patent for a new method for producing Portland composite cement (PCC) using calcined clay and recycled waste cement. GlobalData News has reported that the process involves grinding clay with quartz and feldspar and calcining the clay, before mixing it with the cement. The PCC’s cement content varies from 30% to 80%, while its calcined clay content varies from 10% to 70%.

Mexico: Cemex has launched a new process called clinker micronisation, developed at its Research and Development Center in Switzerland. The method enables cement producers to lower the clinker factor of their cement by up to 50%, while maintaining its strength. It also offers the additional benefit of allowing concrete users to reduce the proportion of cement in their mixes.

CEO Fernando González said “We are finding new ways to boost our decarbonisation roadmap in the production of cement and concrete. We remain committed to achieving our ambitious 2030 decarbonisation goals on the path to becoming a Net Zero company by 2050.”
