Chemical Management

All chemicals use in our production processes are tested to assess their impact on human heath and the environment, before they are actually used. This is just one of the ways through which we strive to minimize potentially harmful effects of our products on consumers and the planet.

Chemical substances are handled through strict internal procedures, throughout their entire cycle, from their arrival at our warehouse to final disposal. New chemical substances are subject to extra-precautionary measures; their purchase requires a preliminary impact assessment and approval through a more complex review procedure. We also implement measures in accordance with the Voluntary Agreement for Reducing Chemicals, to which we are a contracting party, to minimize the detrimental impact of chemical substances on human health and the environment.

Minimizing Air Pollutant Emissions from Chemical Substance Storage Facilities
Minimizing Air Pollutant Emissions from Chemical Substance Storage Facilities

At Hanwha Techwin, we exercise the utmost vigilance to prevent chemicals stored at our plant from releasing toxic air pollutants into the environment. All storage tanks used for hazardous chemical substances are equipped with an air cleaning unit, and emissions of toxic gases are minimized, using submerged injection methods.

Use of a Safer pH Adjustment Agent for Wastewater Treatment

Sulphuric acid, previously used as a pH adjustment agent during oxidation of cyanide-contaminated water, has now been replaced by aluminum sulfate, a substance significantly less harmful to human health. The use of aluminum sulfate has also contributed toward greater stability of our wastewater treatment system.

Surveillanvce Cameras Installed at Chemical Substance Storage Facilities

To improve our response capability to accidents at our indoor chemical substance storage facilities, we set up surveillance cameras, operating around-the-clock, assisting and complementing human surveillance efforts. Our regularly-scheduled drills are conducted with an emergency scenario, so that we may swiftly intervene in case of an accident.
