Air Pollution Prevention

Efforts to Reduce Environmental Impact by Introducing Catalysts for Treating Exhaust Gas

We are making efforts to reduce emissions of SOx, NOx, and dust to prevent air pollution. We ascertained the emissions of the respective substances, and installed proprietary De-NOx equipment and scrubbers to reduce NOx and dust, respectively, and reduced fuel oil consumption and shifted to natural gas to reduce SOx. We also use proprietary catalysts for treating exhaust gas to purify unutilized materials and other emissions from our manufacturing processes.
None of our emissions exceed the values we agreed upon with the municipal and prefectural governments.
