Chemical Substance Management
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 Types
Change 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 Use of Chemical Substances
In fiscal 2022, 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 2022 are listed below, and we will continue to work to reduce chemical substance use.
- JAE:
-
- Reduced the amount of deposited gold needed for gold plating
- Reduced registered substances by rationalizing production, and reduced substitutes and organic solvents
- HAE:
-
- Reduced bromopropane by reviewing the frequency of plating preprocessing solution replacement
- Reduced sodium hydroxide usage by reviewing treatment process
- Reduced ferric chloride by reviewing the input volume of acid-alkali treatment agents
- YAE:
-
- Reduced part cleaner purchases and cleaning solution usage
- FAE, SAE:
-
- Reduced use of registered chemicals
PRTR Data
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 substances, the amount of antimony and its compounds used in molding materials decreased at JAE and HAE due to fluctuations in production. We will continue to limit the amount used by using remanufactured products (recycling) and reusing agents more than once (reuse) by reviewing the frequency of treatment solution replacement.
Note: Antimony and its compounds, inorganic cyanide compounds, hexavalent chromium compounds, toluene, nickel, nickel compounds, hydrogen fluoride and its water-soluble salts, lead, 1-bromopropane, methylnaphthalene, and ferric chloride.
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 ethanol 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.
