Managing Chemical Substances and Environmental Risks

Murata strives to minimize environmental risks of business activities affecting the local community and to be ready for handling any problems promptly when they happen. To this end, we do our best to disclose information pertaining to such efforts including inviting local residents to company tours so that they can understand Murata's environmental conservation activities.

Avoiding Environmental Risk

Preventing Environmental Accidents and Pollution

We are aware of the significant environmental risk accompanying the use of chemical substances, and we are taking steps to avoid pollution. We take into particular consideration the degree and duration of environmental impacts when storing and transporting chemical substances within our facilities, applying four voluntary standards for proactive prevention.

We contract legally certified waste disposal specialists for the disposal of industrial waste in Japan and overseas, and we visit their processing facilities regularly to ensure proper treatment. We also conduct surveys to minimize the risk of soil pollution caused by ground deformations when constructing plants. Please note that, in fiscal 2015, no event such as a serious environmental accident or a case of environmental pollution in excess of a regulation value occurred.


Voluntary Standards for Prevention of Environmental Accidents and Pollution

  • Prohibition against Underground Storage Tanks
    In principle, storage tanks for fuels, organic solvents, acids, alkalis and waste liquids and wastewater tanks for treating wastewater will be located above ground. If it is unavoidable that a tank be placed underground, it will be a double-walled tank.
  • Permeation Barrier Coating
    Locations where such fluids as fuels, organic solvents, acids, and alkalis, as well as waste oil, are handled will be provided with a bed made of a permeation barrier coating or stainless steel.
  • Prohibition of Underground Piping
    Pipes for transporting such fluids as fuels, organic solvents, acids and alkalis, as well as waste liquids, will be located above ground.
  • Emergency Containment Structure
    Workplaces where liquids are received or where waste liquids are discharged to or from tank trucks or the like will have a structure for immediately containing any leakage if an accident occurs.

Communications with Local Residents about Environmental Risk

We consider minimizing the impact of our business activities on local communities to be one of the most important aspects of our corporate social responsibility, and we work hard to respond swiftly if a problem occurs.

In fiscal 2015, the Murata Group's plants received 3 complaints regarding noise and tree planting, and we quickly resolved these issues in consultation with local residents.

We also strive to promote information disclosure, by such means as inviting local residents to tour around our operating sites, so that they can better understand our active environmental efforts.

Managing of Chemical Substances and Environmentally Hazardous Substances

Management and Emissions Reduction for Chemical Substances

At Murata, we record data on the chemical substances we use in our domestic plants in a database, and we use a system that allows us to easily understand and manage the status of use of individual chemical substances.

We use this system for the discharge and transportation calculations required by the Act on Confirmation, etc. of Release Amounts of Specific Chemical Substances in the Environment and Promotion of Improvements to the Management Thereof (PRTR Law).

Of the 462 classes of substances that are subject to reporting under the terms of this law, in its domestic Group operations between April 1, 2016 and March 31, 2017, Murata used one ton or more of 27 classes of substance including toluene, xylene, and lead and lead compounds. The amounts used are shown below.

Soil and Groundwater Contamination Surveys and Decontamination

Implementation of Surveys of Contamination and Decontamination Measures at Business Sites

Murata has been quick to carry out surveys on soil and groundwater contamination caused by past business activities and has actively worked toward early remediation. 

Depending on the properties of the soil, the concentration of contamination, and the position of the contamination source, we apply the on-site bio method, the on-site iron powder method, or the on-site oxidation and decomposition method, or other state-of-the-art technologies to enable decontamination of the area. In addition, we install wells at the boundaries of the facilities in question to enable us to monitor the status of decontamination of the groundwater.
