Various wastes from various industries have harmful effects not only on humans but also on eco-systems.


Accordingly, a variety of technologies are being developed to dispose of such wastes safely, and actually, its relevant regulations are also reinforced. Particularly, waste containing mercury is regarded as considerably hazardous waste due to its high toxicity, volatility and fluidity.

Use of mercury is gradually on the decrease, but actually, large quantities of waste containing mercury are produced in the middle of the industrial process, such as coal-fired power generation facility, petroleum refinery, and iron & non-ferrous metal production facility.

In addition, the fly ash and bottom ash discharged from various waste incinerators are the wastes containing high-concentration mercury, and in case the waste is buried without a proper treatment procedure, it could cause serious soil pollution through elution into soil.

Therefore, the advanced fusion technology research institute is conducting diverse research works for developing effective waste treatment technology, and particularly, the institute is put its focus on Stabilization/Solidification technology.


Stabilization/Solidification technology solidifies waste to make it possible to easily manage and control wastes after stabilizing the waste containing mercury chemically by converting waste containing mercury into the state of low solubility, or into the non-elutable form. In addition, this technology prepared solidified matter with the application of Sulfur Polymer Stabilization/Solidification (SPSS) and Chemically Bonded Phosphate Ceramics (CBPC) after converting the mercury contained in waste into the stabilized form of HgS using sulfur having good reactivity with mercury.
