South Korea: Sampyo Cement, the Korea Cement Association, LG Chem, Hyundai Rotem and the Korea Engineers Alliance have partnered to tackle the issue of chlorine dust from alternative fuels (AFs). AJU News has reported that LG Chem will develop a product to prevent chlorine dust from attaching to the insides of cement kilns.

Hyundai Rotem will supply chlorine dust treatment facilities for the project.
