Environmental Management

Print this page

Basic Philosophy

Our environmental management system, operating on the environmental policy shared by the entire Group, ensures systematic and effective environmental preservation activities. Under this system, all Group companies strive to achieve the Eco Vision.

Promotion system

Our group has a matrix-type structure including business departments and respective regions, promoting environmental activities while having individual roles clarified. Each department is expected to manage its own targets on items relevant to business activities, for example, “Global warming”, “Natural resources”, “Toxic, hazardous chemicals”, and “Key quality” under the Global Eco Vision 2020 for the practice along with business activities. Meanwhile, we take the initiatives to such activities as compliance of regulations, and communication with local society mainly on the region basis in accordance with action plans. Various sub-committees are set up as the cross-functional team across the department for promoting activities.
The activities will be confirmed with respect to the progress toward the target, and task in Central Environmental Committee at which President, directors, department managers, environment control managers in the respective regions, and chairpersons of the sub-committees are present for continuous improvement.

The Establishment Status of our Environmental Management System

We received ISO 14001 consolidated certification for NGK SPARK PLUG CO., LTD. and 11 group companies in Japan. In fiscal 2016, we received ISO14001:2015 certification on December through upgrade audit.
Other domestic and overseas group companies have already received the ISO14001 certification, individually, resulting in 18 overseas group companies which have received the certification in the end of the fiscal 2016.

Environmental Risk Management

Inherent in business activities are various risks including environmental incidents and pollution. NGK SPARK PLUG's GROUP identifies these risks and endeavors to reduce and/or prevent them.

PCB Control

PCB wastes have been stored at our Headquarters Plant, Komaki Plant, and CS Nakatsugawa under strict control for proper disposal.
In fiscal 2016, we completed proper disposal of PCB wastes stored at SparkTec WKS.

On-site Confirmation of Waste Material Treatment

We regularly visit our waste disposers to confirm that consigned waste materials are being processed in accordance with our agreement. In fiscal 2016, we visited 65 companies.

Handling of Asbestos

We have been taking appropriate measures to prevent health hazards from asbestos. All asbestos used in our facilities has been completely removed. Some asbestos is still present in buildings as insulators, and we will continue to adhere to stringent control measures and periodical confirmation.

Preventing Chemical Leaks

In order to prevent soil and water contamination caused by chemical leaks, we have been implementing countermeasures involving equipment that includes preventing leaks through the development of double layered storage tanks and the early detection of leaks by installing pipes above ground. Wastewater treatment facilities of the respective plants discharge the wastewater only confirmed to be harmless through monitor measurement under routine management.

Drills for Emergency Situations

We hold regular drills for emergency situations to prepare for unforeseen accidents, etc. Each department identifies potential environmental accidents to prevent associated adverse environmental impacts.
Ceramic Sensor held drills for blocking drainage assuming that wastewater in excess of the maximum limit value accidentally flows outside the premise.

Compliance Status

To ensure compliance with environmental laws and regulations as well as agreements with local municipalities, etc., we set stringent voluntary standards to prevent violations and complaints.
In fiscal 2016, there were two instances of violations of laws and regulations in Japan, and two instances of demand for improvement concerning noise. As each of these involved problems in mechanisms for management and monitoring, we immediately carried out countermeasures, working to prevent recurrence.

Handling Violations and Complaints in Fiscal 2016

Company Situation Countermeasures
Violation NTK Ceramic Failed to submit the external industrial waste carry-in report no later than 30 days prior to the first day of scheduled carry-in period. Tried to confirm whether or not the external industrial waste carry-in report has been submitted with respect to all the contracted waste-disposal service providers so that the respective submission terms are listed and managed.
Violation NTK Ceramic Failed to set up bulletin boards as prescribed in Waste Management Law at some of Industrial disposal sites. Clarified the management department in charge of Waste Management Law, which is expected to make confirmations twice a year.
Complaint Komaki Plant Received two complaints from neighborhood residents with respect to operations performed by the external service providers during summer vacation.
1 Noise was generated from vacuum vehicle and high-pressure washing vehicle during cleaning operation of cooling tower outside the plant 14 on the north side.
2 Noise was generated from vacuum vehicle and high-pressure washing vehicle during cleaning operation of cooling water tank and tank outside the plant for trial model production on the south side.
As solution for those cases 1 and 2, soundproof sheet was set for noise suppression while reconsidering arrangement of the work vehicle. As for operations for the future, we will examine employment of the work vehicle with low-noise type motor pump in place of the engine-powered vehicle.

Environmental Accounting

What is important in promoting environmental management is to gain a grasp of the costs and effectiveness of environmental preservation activities. We have been adopting environmental accounting since 1999, and in 2003 the accounting scope was expanded to include the entire Group.
In fiscal 2016, our environmental conservation costs were 13,410 million yen on a non-consolidated basis, and 14,327 million yen for the Group, an increase of 15.9% over the previous fiscal year. The economic benefit associated with environmental conservation activities totaled 118 million yen on a non-consolidated basis.

  • Eco-efficiency

    We calculate eco-efficiency by determining net sales per unit of CO2 emissions and generated waste, and endeavor to improve it.

    In fiscal 2016, figures of CO2 emissions and generated waste were worsened compared with those of the previous fiscal year resulting from the temporary waste increase caused by start up of the new plant in addition to the waste increase owing to the steep production rise.

    Environmental Education

    Environmental education is conducted to deepen employees’ understanding of environmental issues, and raise their environmental awareness.
    In fiscal 2016, we held four courses on “Environmental basics”, “Environmental management system”, “Calculation methods for substances with an environmental burden”, and “Environmental laws and regulations (for facilities).
    We published “Environment Handbook” concerning basic knowledge of environment and our approach to take the initiatives, distributed to all the employees including those of the domestic and overseas group companies.
    We are planning to enhance our environmental education program in fiscal 2017 to improve the overall level of the environmental consciousness of Group employees.

    Comment from an environmental education course participant

    Taking course on environmental basics

    Taking the course on environmental basics, I was able to realize the importance of facing with the environmental problem. As media has taken up global environmental issues, this course allows me to understand that effort of every employee may change or solve the environmental problem, and further become more conscious about acting in environment-friendly manner.
    I think there still exists room for improving environment besides such efforts to prevent wasteful use of paper resource on the workplace, and to use public transportation for traveling or the refill container for detergent and the like in daily private life. I will further raise the environmental awareness higher by exchanging views on such issue with colleagues or family. I believe the initiatives for the environmental education may be a great help to actualize better environment.
