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.
