Nigeria: Bauchi State Government, in partnership with Resident Cement, has commenced work on a US$1.5bn cement plant in Diji Village, Gwana District, Alkaleri Local Government Area, according to Arise News.

Resident Cement Group Chairman Abbas Junaid stated that limestone deposits in the area are sufficient to sustain a 10Mt/yr capacity plant for 100 years. The company has begun drilling and will deploy four rigs to complete the project within two months, with full construction of the plant to begin in three months.

US: Heidelberg Materials North America has begun test well drilling at its Mitchell cement plant in Indiana as part of the CarbonSAFE carbon capture and storage (CCS) project led by the Illinois State Geological Survey (ISGS).

The drilling started on 22 January 2025 to assess the geology beneath the plant, which is located in the Illinois Basin, for CO₂ storage potential. The test will evaluate three carbon storage formations to a depth of 2210m to determine if the site can safely store 50Mt of CO₂ over 30 years.

The project began in early 2023 with seismic data collection across 87km of roadways, leading to the installation of the geologic test well.

Greg Ronczka, vice president of Carbon Transport & Storage Development said "This is an exciting step for the project as we learn which potential formations may be suitable to permanently and safely store the CO₂. This knowledge will help us design the injection and observation well network and allow us to prepare a complete and accurate US Environmental Protection Agency Class VI permit application."

Spain: An anonymous source informed the Regional Government of Andalusia about the discovery of a cave with interesting geological features at a quarry run by FYM near its Malaga integrated cement plant. Photographs of the cave subsequently circulated on social media raising local awareness, according to El Español. The local government has commissioned a study to assess whether the site has any archaeological interest that might protect it however the condition of the site is reportedly poor. FYM, a subsidiary of Germany-based HeidelbergCement, has confirmed that activity in that part of the quarry has been ‘paralysed’ while it waits for the study to be completed.
