HCMC– Vinh Long Province has called on ministries to issue preferential policies to make use of coal ash and slag from the Duyen Hai thermal power center as construction materials.
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 in landfills, and as additives for mortar, concrete, and cement.
This solution not only helps ease the shortage of construction materials but also addresses the disposal of industrial waste from thermal power plants.
The provincial People’s Committee is proposing that the Ministry of Construction and the Ministry of Finance promptly issue mechanisms prioritizing the use of coal ash and slag instead of natural resources in traffic and civil construction projects.
The province has also requested the Ministry of Science and Technology to work with relevant agencies to review and improve technical standards for using thermal power by-products in the construction sector, aiming to minimize environmental impacts and enhance economic efficiency.
As of the end of last year, around 4.37 million tons of coal ash and slag remained at the Duyen Hai thermal power center in Vinh Long. Since the beginning of this year alone, nearly 700,000 tons of new coal ash and slag has been generated there.
