Philippines: A recent study from Cebu, Philippines presents a method for reducing greenhouse emissions in the cement industry. The research, supported by the Department of Science & Technology (DOST) of the Philippines, focuses on partially substituting cement with coal fly ash (CFA). According to the University of San Carlos researchers, CFA's efficacy as a cement substitute depends on its source, with variations in quality, performance, and water requirements when used in paste and mortar formulations.

The study evaluated CFA from a Philippine power plant, examining its use as a partial cement substitute. Researchers designed paste and mortar mixtures with different CFA-to-binder ratios and water-to-binder ratios. The study revealed that increasing the amount of CFA in cement up to 20% by weight could enhance compressive strength, ‘outperforming’ pure cement mixtures.

The study concluded that substituting a portion of cement with CFA not only reduces greenhouse gas emissions but also improves the compressive strength of the resultant material.

Thailand: Chair of the Thai Cement Manufacturers Association (TCMA), Dr Chana Poomee, announced the company’s new strategy, called 'TCMA Synergising the Actions toward Net Zero 2050'. This strategy aims to drive the cement industry towards clean energy transition, connect with global green funds and address climate change.

The vision involves four key missions for 2024-2026, including developing low-carbon cement, enhancing resource-efficient mining practices, building an integrated waste-to-value ecosystem, and transitioning to clean energy.

The TCMA also aims to reduce its CO₂ emissions by 6.9Mt/yr by 2030. Collaborations with various partners, including the Thailand Fellowship Cement Manufacturers and the Thai Bankers Association, are planned to leverage innovation and government policy support.

Uzbekistan: Uzbekistan produced 1.35Mt of cement in January and February 2024. This production volume shows a year-on-year increase of 50%. In February 2024, the country produced 724,700t of cement.

France: Heidelberg Materials has announced plans to close two of its plants in France - Beffes and Villiers-au-Bouin - by October 2025. This move is part of the company's restructuring efforts aimed at accelerating its decarbonisation efforts and focusing more on low-carbon products.

The decision comes amid a decline in cement sales in France, attributed to weak demand in the construction sector. 170 employees are affected by the impending closures of these plants, according to the company.

These closures align with Heidelberg Materials' commitment to focus on lower carbon alternatives, enhance energy efficiency, increase the use of alternative fuels, and reduce the clinker content in its cement products in France.

China:  The UK-based Carbon Disclosure Project Carbon Majors database has released its Carbon Majors Database. The database quantifies the historical CO₂ emissions of 122 of the world's major emitters, among them the Chinese cement sector.

Notably, China's cement industry has been a significant contributor to global emissions. In the period up to the end of 2022, China's cement sector has produced 23,161Mt of CO₂, accounting for 1.3% of the global emissions recorded during this period. From 2016 to 2022, the cement industry in China emitted 8.16Bnt of CO₂, accounting for 3.2% of global emissions.

Figures for the cement sector include process emissions from the calcination of limestone, but exclude emissions from fuel and electricity used in production.
