Thai Nguyen has wrapped up an inspection over the outdoor mountain of hazardous waste. Tisco’s waste was mostly from its two subsidiaries – Luu Xa steel mill and the pig iron mill.
The former makes ingot steel with the capacity of 450,000 tons per annum, using pig iron, scrap steel and supporting materials. The production discharges a big volume of furnace dust which is collected through two dust filter bag systems.
The mill reported that since 2010, the volume of dust generated had reached 38,159.642 kilograms, one fourth of which had been transferred to treatment companies. The remaining dust has been kept in three areas.
The No 1 dumping ground had 5,880 tons of hazardous waste. There are 20,670 tons on No 2 and 1,316 tons at the old warehouse.
