Improving Chemical Substance Management
In consideration of workers’ safety and health, and looking to lower environmental impact, we are working to improve the management of chemical substances. We will present examples of our initiatives.
Reduction of Chemical Substances
Monitoring Registration of Chemical Substance Product TypesChange in the number of chemical substance product types at production sites in Japan is as visualized in the below graph. The reason that the JAE site has more chemical substances than other production sites is because it is not only involved in production but is also a development plant and uses chemical substances for testing. The JAE Group monitors whether unnecessary chemical substances have been registered so that the number registered does not increase any further. The Group will move aggressively to reduce the volume of chemical substances used, as shown below.
Reduction of Chemical Substances
In fiscal 2024, we continued as in the previous year to conduct our activities with the goal of reducing the amount of chemical substances used by selecting designated substances for each domestic production base in order to reduce our environmental impact. The main chemical substance reduction activities for fiscal 2024 are listed below, and we will continue to work to reduce chemical substance use.
- JAE:
- ・Reduced gold usage in the plating process
・Reduced 1-bromopropane consumption
・Reduced ink consumption
- HAE:
- ・Reduced sodium hydroxide consumption by revising the treatment process
・Reduced 1-bromopropane consumption
・Reduced lacquer solution consumption by revising the dilution ratio of the treatment liquid
・Reduced use of anti-scaling agents in wastewater treatment equipment
- YAE:
- ・Reduced number of regulated chemical substances
・Reduced cleaning liquid consumption
・Reduced both purchases and consumption of parts cleaner and cleaning solution
- FAE:
- ・Reduced number of regulated chemical substances
- SAE:
- ・Reduced 1-bromopropane consumption
- MGC:
- ・Reduced both purchases and consumption of cleaning agents
PRTR Information
The graph below shows the change in the amount of chemical substances (see note) subject to the PRTR Law (*use cursor to view definitions) handled at production sites in Japan.Regarding PRTR-designated substances, the amount of 1-bromopropane used for cleaning decreased at HAE and SAE due to production fluctuations and substitution. Going forward, we will continue to reduce handling volumes by revising treatment processes, using recycled products, and promoting repeated reuse.
Note: Antimony and its compounds, inorganic cyanide compounds, hexavalent chromium compounds, nickel, nickel compounds, hydrogen fluoride and its water-soluble salts, lead and its compounds, 1-bromopropane, and methylnaphthalene.
VOC Information
The total volume of chemical emissions of VOCs (use cursor to view definition) and related substances for production sites in Japan is shown in the graph below. Atmospheric emissions of isopropyl alcohol and methanol used as a cleaning agent decreased due to fluctuations in production. In order to curb the amount of atmospheric emissions, the Group is considering reduction measures such as installing dampers within the equipment so that excess VOCs are not released into the atmosphere when the equipment stops. In addition, we are improving the airtightness of containers and adjusting the amount handled. VOCs (Volatile Organic Compounds) Organic compounds that easily evaporate, VOCs are many and varied, such as toluene, xylene, and ethyl acetate. These are included in paints, cleansers, thinners and other substances.
