The treatment of residues has been a problem for chromium chemicals worldwide, with even the most advanced manufacturing techniques in developed nations unable to eradicate pollution completely.
In China, the metal chromium conversion rate is only 75 percent and overall source utilization rate is less than 20 percent.
Statistics from China's chromium chemicals industry show the production of every ton of chromium chemicals results in the discharge of 2.5 tons of highly toxic residues, causing serious pollution to water, soil and air.
The chromium industrial recovery rate of BlueStar's new technology was more than 98 percent, up 20 percent from the traditional techniques, and was 8 to 9 percent higher than the world's most advanced methods.
Compared with traditional techniques, BlueStar's new project consumed 20 percent less power, and produced 80 percent less chromium residue, said the statement.
