Environmental Considerations; Atmosphere
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.
VOC emissions
- * (1) Data for 2022 and before: Consolidated data for Group companies in Japan and data for former Hitachi Chemical’s overseas Group companies. Total for eight targeted substances for former Showa Denko Group and total for 50 targeted substances for former Hitachi Chemical Group; (2) Data for 23 targeted substances for 2023
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.
