Environmental Considerations; Atmosphere
Basic ideas and policies
The Resonac Group is working to reduce the release of chemical substances to the environment, including air pollutants (NOx, SOx and dust and soot), volatile organic compounds (VOCs), substances included in the target of voluntary surveys by the Japan Chemical Industry Association (JCIA), and those regulated by the Japanese Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (“PRTR law”). We will contribute to the creation of a sustainable society by setting our own management criteria for exhaust gas, promoting fuel conversion, and improving our manufacturing processes to minimize the release of hazardous substances and pollutants on a continual basis.
Reducing emissions of hazardous air pollutants
We are working to reduce the use of hazardous air pollutants designated by the Japan Chemical Industry Association (JCIA), substances stipulated in the PRTR Act, and other key chemical substances that we handle by switching to alternative substances and improving recovery and recycling rates.

Reducing our environmental impact on the air
To reduce emissions of NOx, SOx, dust and soot, and other substances having adverse effects on the air, the Group continued advancing a variety of measures including fuel switching, improvement of combustion methods, proper operational management of desulfurization and denitrification devices, and reduced fuel consumption through waste heat recovery.
PRTR law-regulated substances and substances included in the JCIA’s target of voluntary surveys
In order to reduce the release of these chemical substances to the environment, we will improve the related processes and facilities and install exhaust gas incineration equipment.
For the PRTR law-regulated substances and those that are discharged in large amounts on an annual basis in particular, we are making reduction plans for each of our sites and implementing intensive measures for the reduction. In fiscal 2020, we substantially reduced the release amount due to the improvement of exhaust gas treatment equipment at affiliated companies in Japan. We will also work to do better by engaging in risk communication with those living in areas around our sites and local governments to deepen mutual understanding.
We discharged no such substances to soil.
