Initiatives to Prevent Air Pollution<\/h2>\n\n\n\n

To prevent air pollution, we monitor emissions of SOx, NOx, dust, and VOCs. We reduce SOx emissions by lowering fuel oil consumption and switching to natural gas, NOx emissions by installing denitrification equipment developed in-house, and dust emissions by installing scrubbers. We also use proprietary exhaust-gas treatment catalysts to remove unreacted raw materials and other substances from process exhaust gases.
All emissions remain below the agreed limits with local governments or the applicable regulatory limits under laws and local ordinances for each site.<\/p>\n\n\n\n
