Argentina: Cement despatches in August 2025 totalled 0.89Mt, down by 0.4% year-on-year from August 2024, according to the AFCP. Volumes fell by 0.2% month-on-month.

However, cumulative despatches from January to August 2025 reached 6.59Mt, an 8% increase from 6.08Mt in the same period of 2024. Cement imports in August 2025 stood at 298t, taking the year-to-date total to 1597t.

Vietnam: Vinh Long Province has called on national ministries to introduce preferential policies to encourage the use of coal ash and slag from the Duyen Hai thermal power centre as construction materials, reports The Saigon Times. According to the Vietnam Cement Association, coal ash and slag from thermal power plants have been certified by the Institute for Building Materials under the Ministry of Construction as suitable for use as cement additives, which could reportedly help to ease shortages of construction materials while addressing the disposal of industrial waste in landfills.

The provincial People’s Committee has proposed that the Ministry of Construction and the Ministry of Finance issue mechanisms that prioritise coal ash and slag over natural resources in traffic and civil construction projects. It also called on the Ministry of Science and Technology to work with agencies to review and update technical standards for using thermal power by-products. By the end of 2024, 4.37Mt of coal ash and slag had accumulated at the Duyen Hai thermal power centre in Vinh Long. Nearly 700,000t more has been generated since January 2025.

Europe: PyroGenesis has signed a US$871,000 contract with a European cement industry customer to supply a plasma torch system for a calciner. The client’s name has not been disclosed for competitive and confidentiality reasons. The system will replace fossil fuel-based heating with plasma technology to provide a ‘cleaner, more efficient’ method for high-temperature calcination, according to the company. Delivery is scheduled for the first quarter of 2026.

Ireland/UK: Mannok has completed Phase 1 of a two-phase upgrade to its pyroprocessing system with the installation of a new satellite burner in collaboration with FLSmidth. The €2.5m project enables the use of solid recovered fuel (SRF) as a replacement for coal, achieving up to 30% substitution and reducing CO₂ emissions by 23,000t/yr.

Phase 2 will involve upgrading the main burner to a Jetflex system, targeting 65–70% coal substitution across the kiln. Mannok produces about 1.4Mt/yr of cement for customers across the UK and Ireland.

Japan: Mitsubishi UBE Cement Corporation (MUCC), Osaka Gas, Daigas Energy and Saibu Gas have successfully tested natural gas co-firing at MUCC’s Kyushu Plant in the Kurosaki area. Using a newly developed burner, the companies replaced 40% of coal with natural gas at commercial scale without affecting kiln stability, product quality or environmental performance.

The burner was developed using MUCC’s coal combustion expertise alongside Osaka Gas and Daigas Energy’s gas combustion and simulation technologies, with Saibu Gas supplying natural gas from LNG tank trucks. MUCC said the trial paves the way for full-scale implementation and supports future use of e-methane in cement kilns.

MUCC aims to cut CO₂ emissions by 40% by 2030, compared to 2013 levels, and achieve group-wide carbon neutrality by 2050 under its medium-term management strategy “Infinity with Will 2025 – MUCC Sustainable Plan 1st STEP.”
