Conformance to the PRTR Act
The balance sheet of substances used by the NEC Group among the chemical substances that are subject to the PRTR act (Class I Designated Chemical Substances: 462 substances) is summarized in the following illustration.
Compared with the report of the previous fiscal year, total volume handled is increased due to increase in production volume. Compared with the report of the previous fiscal year, transaction volume has decreased due to a review of manufacturing processes to more effectively utilize resources and a reduction in production volume.
For chemical substances released into the atmosphere and public water bodies (including discharges into sewage systems), NEC has set its own voluntary standards, which are more stringent than the levels required by the act, and ensured that these standards were strictly met.
