Ashes released from Nghi Son 1 Thermal Power Plant becoming 'expensive'

In 2021, the amount of ash, slag and gypsum released from Nghi Son 1 Thermal Power Plant (Nghi Son town, Thanh Hoa province) will be consumed 100%. Thereby, it could ensure safe plant operation, sustainable development to meet environmental standards.

Coal consumption demand is about 1.5 million tons/year. The mixture of ash, slag, and gypsum is produced at about 430,000 tons/year.

In the period of 2019 - 2020, the plant will process and consume 100% of fly ash and gypsum, while the amount of slag consumed over the years is 41% and 53%, respectively. In 2021, the consumption of ash, slag and gypsum will still maintain at 100%. The plant has treated and consumed a significant portion of the slag stored in the yard from previous years. Slag is purchased directly from the plant by the underwriter and distributed to the receiving units for the production of building materials such as cement and unburnt materials.

Nghi Son Thermal Power Company has been currently implementing a contract with Minh Phong Investment Joint Stock Company, supplying ash, slag, and gypsum for factories such as Nghi Son Cement Factory, But Son Cement Factory, Long Son Cement Factory, But Son Brick Factory, Son Trung Hieu Brick Factory, Nam Vang Bim Son Brick Factory, Long Son Trieu Son Brick Factory, etc. According to the design, the landfill area of Nghi Son 1 Thermal Power Plant is 42 hectares with a storage capacity of 5.2 million tons, while the volume already on the dump is just nearly 1.2 million tons by the end of December 2021. Therefore, Nghi Son 1 Thermal Power Plant enjoys good conditions to focus on production and business activities as well as control the quality of ash and slag.
