Reduction of Emissions of PRTR Substances

In FY2016, we emitted 60 chemical substances whose emissions must be registered in accordance with “the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (PRTR law)”. The main substances emitted were formaldehyde and n-hexane. Formaldehyde is used as a reaction solvent, while n-hexane is found in naphtha, which is used as a fuel or feedstock. Emissions of n-hexane also decreased in FY2016 because we changed the feedstock for manufacturing ammonia.

We emitted a total of 1.9 tons of these substances, including 1.5 tons into the atmosphere and 0.4 tons into waters. Emissions into the atmosphere decreased from the previous fiscal year. We will continue to take steps to control the emissions. We did not emit these substances into the soil.
