Appropriate Management of Chemical Substances

To ward off environment contamination with chemicals and adverse effects on human health, we have banned the use of forbidden substances, implemented a chemical management framework, and are working on reducing emission volumes.

Chemical Management Framework

The TAIYO YUDEN Group has adopted its own Chemical Substances Control Standards. These standards define which substances are to be prohibited, reduced, and managed.
To tighten up control, we set up a chemical substances management structure specifying the persons in charge and their responsibilities.

Chemical Management Framework

Target Chemicals

Prohibited substances Cadmium, compounds containing cadmium, mercury, compounds containing mercury, hexavalent chromium compounds, etc.
Substances to be restricted Lead in ceramic in capacitors, lead in ceramic or glass frit, dibutyltin compounds, etc.
Substances to be reduced Toluene, REACH substances of very high concern (SVHC), nickel and chemical compounds containing these substances, etc.

PRTR Law Compliance

In order to reduce the risks that chemicals impose on the environment, the TAIYO YUDEN Group report to the government the amounts of chemicals released to the environment (air, water, and soil), and waste chemicals transported and recycled under the Japanese Law for Pollutant Release and Transfer Register (PRTR). The government publishes the records and a database of these quantities making them widely available to members of the general public.

PRTR Restricted Substances

PRTR Restricted Substances

Note: Target chemical substances and their incoming amount shown refer to substances for which their incoming amount exceeds 1 ton in compliance with the PRTR Law.
Emission: This refers to the total emission into the atmosphere, water, and soil.
Amount Transferred: This refers to the amount whose disposal is outsourced to an industrial waste contractor outside the business facility concerned.

Ozone-depleting Substances

We do not use ozone-depleting substances in our production processes. Although we use HCFC as a coolant in air conditioners and other equipment, we carry out appropriate collection and disposal.
