Environmental Pollution Prevention

Approach

The NGK Group operates group-wide environmental management frameworks and an Environmental Management System (EMS), and continues to promote initiatives to prevent environmental pollution in accordance with the NGK Group Environmental Policy.

Promotion Framework

Initiatives

Chemical Management

The NGK Group complies with laws, guidelines, and other rules in Japan and overseas by maintaining a proper level of chemical management and continuously working to improve it. Before a department uses a new chemical substance, the Chemical Substances Safety Committee determines whether it may be used and provides guidance on precautions for its use and disposal. For chemical substances that are already used by a department, each site’s chemical substances committee and chemical substances patrol team confirm the state of chemical management and provide the necessary guidance. We also monitor changes in chemical substance-related regulations and shares information across the Group to further improve its level of chemical management. Group companies in and outside Japan also survey and understand regional rules and regulations and implement proper chemical management.

Chemical Management Flowchart
This is a chart showing the chemical management process flow. The process flow is as follows. After the department using the chemicals submits an application, the division checking conducts a review and provides guidance. If the application is approved, the Purchasing Department registers purchasing information, and the department using the chemicals uses the chemicals while implementing appropriate control.

Commitment Concerning Hazardous Substances

To comply with legal disposal deadlines for PCB-containing waste, the NGK Group conducts thorough investigations, including at its Group companies, and proceeds sequentially with extraction, storage, and disposal. We outsource disposal to contractors who hold PCB disposal permits and check to make sure disposal is handled properly.

Reducing the Risks Inherent in Toxic Substances

The NGK Group conducts thorough investigations, including at its Group companies, to comply with legal disposal deadlines for PCB-containing waste, and proceeds sequentially with extraction, storage, and disposal. It outsources disposal to contractors who hold PCB disposal permits and checks to make sure disposal is handled properly.

Environmental Conservation

The NGK Group properly manages emissions from air pollutant-emitting facilities and water quality at wastewater treatment facilities to prevent impacts on people’s health and living environments. In addition to the items stipulated by laws and ordinances, we have established voluntary management items and conduct periodic measurements and constant monitoring of critical items. We have also introduced mechanisms such as alarms and equipment shutoff to prevent exceedances and ensure compliance with regulatory limits. In accordance with the Act on Rational Use and Appropriate Management of Fluorocarbons, we centrally manage equipment data and information on inspections, maintenance, and leak response in a database. Through this system, we ensure proper management of fluorocarbons and work to curb undue emissions (improper emissions).
