Abstract

Due to rapid industrialization and economic growth, the generation of coal ash from coal-fired thermal power plants is increasing in Vietnam. As of 2020, coal-fired power accounts for 49.3% of the total power supply in the electrical industry and leads to a large generation of coal ash every year. The amount can be expected to increase to up to 30 million tons according to the master plan for electricity development, with 52 coal-fired power plants expected to be in operation by 2030 and more than 422 million tons of coal ash being stored. In recent years, the management and recycling of coal ash have played an important role in economic and social development. Besides protecting the environment, coal ash is also widely used in construction. Based on survey results, thermal plants do not possess sufficient capacity for storage of coal ash, especially from small-scale and old plants (which face the risk of closure). It is recommended to improve the technical standards for handling, reuse, and recycling of coal ash and to establish a collaborative system and framework among enterprises, government, and research institutes to promote the effective reuse and recycling of coal ash in Vietnam.
