The Role of Cement PlantWe save our environment by recycling to replace natural resources with waste in the cement production process
The Role of Cement Plant in Resource Recycling System
Cement kilns enable us to make a stable resource recycling by incinerating alternative raw materials and waste fuels. Inside temperature up to 1,450°C is high enough to decompose an organic matter and melt down a heavy metal.
Resource recycling contributes to reducing CO2 emission as well as fine-dust emission.
We periodically publicize the status of recycling resources by the voluntary agreement with the Ministry of Environment (March 4, 2009).

Since the fourth quarter of 2014, we have disclosed the results of radiation(light) measurements of imported coal and cement. If you go to the site below, you can download related materials.
