Vietnam looks to boost use of coal ash and slag in construction
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.
PyroGenesis wins US$871,000 contract for European cement plant
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.

Delivery is scheduled for the first quarter of 2026.
Mannok installs satellite burner as part of €2.5m kiln upgrade
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.
Mitsubishi UBE Cement tests natural gas co-firing at Kyushu Plant
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.”
Nepal Supreme Court orders relocation of cement plants near Lumbini
Nepal: The Supreme Court has issued a landmark directive requiring industries within 15km of Lumbini, the birthplace of Lord Gautam Buddha, to relocate or shut down within two years to preserve the UNESCO World Heritage site. The ruling directly affects around 15 companies, including Arghakhanchi Cement, Jagdamba Cement and Brij Cement, according to The New Business Age newspaper.
The Court annulled earlier government decisions that allowed industrial activity in the area, declaring that protecting Lumbini’s sanctity was of global cultural and spiritual importance. It also prohibited capacity expansion or capital investment in existing plants and reaffirmed a 2009 resolution banning new carbon-emitting industries near the site.
Bishnu Prasad Neupane, chair of the Saurabh Group, which operates Jagdamba Cement, said that compensation must extend beyond land value if the relocation becomes mandatory, noting that US$142–212m has already been invested in the affected industries. Neupane also said “Grinding units do not burn coal or release carbon emissions. We have installed dust-control systems. Claims that dust travels 15km to reach Lumbini are unfounded.”
Gebr. Pfeiffer to supply grinding plant for JSW Cement in Rajasthan
India: Gebr. Pfeiffer has received an order to supply a cement grinding plant for JSW Cement in Nagaur, Rajasthan. The plant will use an MVR 3750 C-4 vertical roller mill equipped with a latest-generation SLS 4000 BC classifier. The system is designed to grind 132t/hr of ordinary Portland cement to a fineness of ≤8% R45µm or 155t/hr of pozzolanic Portland cement to a fineness of ≤8% R45µm.
Heracles commissions 6.5MW solar power station at Milaki plant
Greece: Heracles Group, a member of Holcim, has commissioned a 6.5MW solar power station at its Milaki plant, equipped with more than 11,000 panels. The facility is now fully operational.
The installation is expected to generate about 10,000MW/yr of electricity, covering a significant share of the plant’s energy needs and cutting CO₂ emissions by 2350t/yr.
India: Ramco Cements has commissioned an 8MW waste heat recovery system at its Ramasamy Raja Nagar cement plant. With this addition, the site’s waste heat power generation capacity has increased from 2MW to 10MW. The producer said its total waste heat power generation capacity has increased from 45.15MW to 53.15MW.
