The Environmental Plant Business of Hyundai Rotem commenced in 1982, and we now lead the Korean environmental market in the fields of design and construction for wastewater treatment plants, industrial wastewater treatment plants, waste incineration plants, industrial waste incineration plants, sludge incineration plants, air pollutant protection facilities, waste reuse facilities, and disposal facilities for livestock wastewater. The world’s first commercial vitrification facility was built in 2008. Vitrification is the process of converting a material into a glass-like amorphous solid that is free from any crystalline structures, either by the quick removal or addition of heat, or by mixing it with an additive.
