Solutions for many projects
The 235-hectare expanded Phuc Dien Industrial Park in Binh Giang District started construction at the end of December 2023. By the end of October 2024, the industrial park had attracted 25 secondary investors.
The above result was a surprise, because right after the groundbreaking ceremony, the Phuc Dien Industrial Park Expansion Project encountered difficulties due to the scarcity of filling materials. The investor needed about 2.5 million m3 of filling materials, but the supply of sand and hill soil was scarce. The Provincial People's Committee promptly considered and allowed the project to use ash and slag from the Hai Duong BOT Thermal Power Plant as filling materials.
Mr. Dao Thanh Tung, Deputy Director of the Phuc Dien Industrial Park Expansion Project, said: "Currently, we have leveled 75% of the industrial park area, of which 50% of the raw materials are ash and slag from the Hai Duong BOT Thermal Power Plant. Through evaluation, this raw material ensures quality. This is an effective solution in the context of current difficulties in the supply of filling materials."
To overcome the shortage of filling materials, industrial parks such as Dai An expansion, Gia Loc ... are using ash and slag, including waste slag from Hai Duong BOT Thermal Power Plant to fill the ground. Cement factories, concrete production facilities, and precast concrete products in and outside the province also use ash and waste slag from thermal power plants as additives and input materials for production.
According to a representative of Dong Hai 27/7 Joint Stock Company, the ash and slag distributor of Hai Duong BOT Thermal Power Plant, the company is selling ash and slag to dozens of units to use as filling materials and additives in cement production.
Ensure standards
The Hai Duong BOT Thermal Power Plant Project (Kinh Mon) is invested by Jaks Hai Duong Power Company Limited, with a total capacity of 1,200 MW. The total amount of electricity generated to the grid from 2021-2023 will reach 6.6 billion kWh, of which 4.3 billion kWh will be generated in the first 6 months of 2024. The plant's production activities generate about 2.25 million tons of ash and slag per year.
To promote the effectiveness of ash and slag from thermal power plants, in recent years, the Government and the Ministry of Industry and Trade have issued many documents directing the promotion of the use of ash and gypsum slag from thermal power plants and chemical fertilizer plants as raw materials for the production of construction materials.
Hai Duong Provincial People's Committee has directed relevant departments, branches, units and Jaks Hai Duong Power Company Limited to synchronously implement solutions to promote the consumption of ash and slag of Hai Duong BOT Thermal Power Plant.
Jaks Hai Duong Power Company Limited has completed the Project for Ash and Slag Treatment and Consumption. The Department of Construction has coordinated with Jaks Hai Duong Power Company Limited and relevant agencies to report to the Ministry of Construction for assessment and certification of slag that is qualified to be used as landfill material. Currently, the plant's ash and slag have been granted a product certificate in accordance with the National Technical Regulation QCVN 16:2019/BXD according to the certificates of conformity No. TQC.5.5078, TQC.11. 5078.1, TQC.11.5078.2.
In order to further promote the consumption of ash and slag, under the direction of the Provincial People's Committee, the Department of Construction coordinated with the Department of Finance to announce the price of ash and slag as construction materials for the convenience of buying and selling units. Accordingly, the price of ash and slag sold by Cam Pha Trading and Industry Joint Stock Company (an enterprise licensed to consume ash and slag of the factory) at the factory's silo area is 25,500 VND/ton, delivered to customers' cars from the factory port is 46,000 VND/ton and delivered to water vehicles at the factory port is 50,000 VND/ton (as of March 2024).
The Provincial People's Committee also requested the People's Committees of districts, towns, cities, the Management Board of Construction Investment Projects, and investors of construction investment projects to increase the use of ash and slag of Jaks Hai Duong Power Company Limited as filling material to replace sand for filling.
With the active participation of all levels and sectors, most of the ash and slag generated at the Hai Duong BOT Thermal Power Plant has been consumed. By September 2024, the total amount of ash and slag generated at the plant was nearly 7.4 million tons and nearly 6 million tons had been consumed.
It can be said that the ash and slag of Hai Duong BOT Thermal Power Plant is a good material for construction and industrial activities in and outside the province. Relevant units are focusing on overcoming limitations in implementing environmental and land regulations so that transportation and consumption can continue to be implemented and ensure regulations.
