Binh Thuan, Deputy General Director of Electricity of Vietnam (EVN) - Nguyen Tai Anh chaired a conference to "promote the ash and slag sale at EVNs coal-fired power plants".
94% of ash and slag sold in 2021:
Mr. Ta Tuan Anh - Deputy Head of EVN Technical - Production Department informed that, at present EVN owns 12 coal-fired power plants (CTPPs) with a total installed capacity of 12,678 MW. These CTPPs on average, every year, consume about 35-40 million tons of coal and eliminate about 7-10 million tons of ash and slag.
In 2021, EVN total volume of ash and slag was 7.34 million tons and the total volume sold was 6.89 million tons, accounting for 94% - the highest volume from 2015 (in 2015 the sale rate was only 30 %).
In recent years, the sale rate of ash and slag in the regions was increased year by year, especially in the northern provinces from Thanh Hoa onwards. For the southern provinces from Nghe An back to Tra Vinh, the sale volume was increased but still could not meet the requirements of EVN.
According to EVN Deputy General Director Nguyen Tai Anh, the recent above results have been reached thank the attention of the Prime Minister (PM) with promulgating Decisions No 1696/QD-TTg dated 23/9/2014, No 452/QD-TTg at 12/4/2017 and Introduction No 08/CT-TTg at 26/3/2021 on promoting treatment and use of ash and slag of the CTPPs. Besides, it must be mentioned the drastic directions of the ministries, agencies, assistance of the localities having CTPPs and participation as well as the cooperation of the partners and EVN CTPPs.
At present, all EVN CTPPs have the certificates on the ash and slag quality achieved by Vietnam Standards for construction, un-burnt, leveling and foundation materials, additives… satisfied regulations on environment and considered “an ordinary industrial solid waste” and managed as a commodity in accordance with the Government Decree No 08/2022/ND-CP and Circular No 02/2022/TT-BTNMT of Ministry of Natural Resources and Environment.
EVN has promulgated modern projects for handling and selling ash and slag and plaster. The units organized to select, sign contracts on consuming ash and slag and long-term, shortage-term plaster with partners.
EVN also actively seeded the new markets for ash and slag consumption, especially for ash and slag of CTPPs in the Vinh Tan area, where ash and slag can be shipped by sea to the Northern and Southern markets.
In accordance with the Government Decree No 08/2022/ND-CP and Circular No 02/2022/TT-BTNMT of the Ministry of Natural Resources and Environment, forced from 10/01/2022, the ash and slag of CTPPs are ordinary industrial solid wastes and normal commodities and they must be managed as commodities.
According to Mr. Nguyen Tai Anh, the ash and slag of CTPPs will become the materials for leveling the roads in the coming time, and exporting ash and slag oversea also is tested and deployed with a goal to sell 100% of ash and slag to domestic and international markets in coming time.
To achieve selling 100 % ash and slag of CTPPs in 2023, EVN asks the PM to approve the specific and preferential mechanisms on using ash and slag for more increasing sale rate of ash and slag in Vinh Tan center particularly and in CTPPs across the whole country generally.
In long-term future, EVN asks PM to direct relevant state agencies to promulgate mechanisms for the investors of transportation and construction projects to use the ash and slag of CTPPs for the highway leveling as the developed countries over the world.
EVN also asks the Ministry of Transportation and Ministry of Construction to early promulgate introductions on norms, unit price of construction, checking before acceptance in transportation and construction projects using ash and slag and proposals to ministries, agencies and especially to the Provincial People’s Committees for supporting them to deploy solutions using ash and slag in transportation and construction projects, perfecting the Vietnam codes related to using ash and slag for leveling and making the automobile road bases.
EVN asks Binh Thuan and Ninh Thuan PPCs to guide the under direct units to create maximum conditions for EVN units to promote the new ash and slag and ones on common accrual grounds, especially the solutions for using ash and slag to transportation and construction projects in Binh Thuan and Ninh Thuan.
For the contractors consuming ash and slag, EVN confirmed to implement the orientations and criteria for electing partners with long-term handling and consuming ash and slag. EVN CTPPs will create comfortable conditions for the contractors in power plants for accepting, transporting ash and slag.
For example, Vinh Tan 2 CTPP has increased the scale of the oil port for accepting the ships transporting ash and slag by the sea. Vinh Tan 4 CTPP is also studying to supplement the sea port to export ash and slag by the sea. Propose the contractors to rightly implement the committed volume of ash and slag in signed contracts.
The representatives of Ministries of Construction, Transportation, Natural Resources and Environment, Industry and Trade and Experts of Construction Materials high appreciated using ash and slag of EVN in recent times and that the ash and slag market with a big potential for construction materials, un-burnt materials, concretes… and they agreed with the proposals of EVN and CTPPs. |
