Ireland: Mannok, Sweden-based minerals company Boliden and the South Eastern Applied Materials (SEAM) research centre at South East Technological University in Carlow, Wexford and Wicklow in Ireland have launched a 30-month project to reduce the embodied CO₂ emissions of cement. The project will investigate possible uses of shale as a supplementary cementitious material (SCM) in cement production and the CO₂ curing of cement paste-based mine backfill. Enterprise Ireland has supplied funding worth €700,000 for the collaboration.

Mannok operations director Kevin Lunney said "We are delighted to be working with SEAM and Boliden on this critical research for the cement sector, which could have many far-reaching benefits for the construction sector more generally. Finding local, viable, low-carbon solutions for the industry can make a major contribution to lowering emissions in Ireland."

Boliden specialist development engineer Adam McElroy and section-mill process head Colum Burns said "This project will greatly enhance our knowledge and understanding of the potential for developing low carbon cement for mine backfill purposes and for utilising backfill systems as a carbon sink. The project will also investigate synergies between the cement manufacturing and mining industries that could enhance the sustainability of both industries."

Azerbaijan: The Azerbaijan Cement Producers Association (ASIA) has held the third Net Zero Accelerator workshop to discuss the final report on its 2050 Net Zero Roadmap. ASIA members, construction companies and government and non-governmental organisations (NGOs) all participated in the two-day event. TurkicWorld News has reported that topics include Azerbaijani cement’s clinker factor, alternative fuel (AF) substitution rate, construction and design aspects, carbon capture and related regulatory frameworks. ASIA will launch its finalised roadmap in partnership with the European Cement Research Academy (ECRA) and the Global Cement and Concrete Association (GCCA) at the COP29 climate conference in Baku, Azerbaijan.

ASIA said "The association is making use of the expertise of the GCCA and ECRA to ensure our roadmap aligns with national policies."

Brazil: Buzzi has finalised the acquisition of the remaining 50% stake in Companhia Nacional de Cimentos (CNC) from Brennand Cimentos, securing full control over the joint venture. The deal, valued at US$311m, was approved by Brazil's Administrative Council for Economic Defense (CADE), according to Movimento Econômico. CNC has been operational since 2018 and has five integrated cement plants and two grinding plants in Brazil, with a total production capacity of 7.2Mt/yr. This acquisition follows initial transactions that began in June 2024.

India: Adani Group is negotiating the purchase of Heidelberg Materials' cement business in India, potentially valued at US$1.2bn, according to Reuters. Heidelberg Materials has been present in India since 2006, and owns four plants with a total capacity of 12.6Mt/yr. The acquisition discussions come amidst increased consolidation in the Indian cement sector, driven by heightened demand due to government investment in housing and infrastructure.

India: Orient Cement has won an order from Madhya Pradesh Power Generating Co to install a clinker grinding unit at Satpura Thermal Power Station, Sarni. The ‘work order’ was issued by the company to install the grinding unit, along with a 25-year fly ash supply contract. Earlier in August 2024, Orient Cement said that it anticipates a robust demand recovery in the second half of the financial year post-monsoon.
