Waste sources seriously treated

Na Duong Thermal Power Company has paid special attention to waste treatment from production.

As for waste, the company usually generates three types of waste, including solid waste, hazardous waste, and ash and slag. Accordingly, every year, the company signs the contract with the People’s Committee of Na Duong Township to collect, classify, transport and treat the solid waste. Regarding hazardous waste, the company has a separate storage area for this kind of waste in accordance with Circular 02/2022/TT-BTNMT dated January 10, 2022. Meanwhile, an average volume of about 350,000 tonnes of ash and slag per year (29,000 tonnes per month) is transported by specialized vehicles to Na Duoi slag dumping site about three kilometers away. According to the Prime Minister’s Decision No.452/QD-TTg dated April 12, 2017, the waste of plant is eligible to make leveling materials and additives for the cement industry. In the coming time, the company will sell ash and slag by auctions to use this raw material properly in construction activities.

Particularly, as for emissions, the company has installed a continuous emission monitoring (CEMS) system for two boilers and since March 2019 has connected online data transmission to the province’s Natural Resources and Environment Center. Also, Na Duong Thermal Power Company has publicized the results of automatic and continuous waste monitoring on the electronic information board at the entrance gate of the company.
