Murata and the Environment

Prevent pollution

Basic approach

Murata has long pursued product-making that harmonizes with local communities under its principle to be “a company whose presence in local communities is a source of pride and joy to those communities.” If environmental pollution arises, it can seriously affect the health and lives of local people, not to mention the natural environment. Therefore, we regard environment pollution risk as a core issue and ensure responsible actions, always being mindful of the potential impacts of our business activities on the local environment. Additionally, while stricter regulations are being introduced as a recent global trend, we are promoting active initiatives ahead of such enforcements. Through these efforts, we will reduce environmental impact wherever possible and make products in harmony with the local communities.

Our goal

Murata aims to reduce environmental burden and realize manufacturing that harmonizes with society by pursuing sustainable business processes that are not restricted to conventional frameworks.

Governance

At Murata, we strictly comply with environmental management requirements and applicable laws and regulations based on our group-wide EHS (Environment, Health & Safety) Management System. Specifically, we identify risks and opportunities related to environmental pollution prevention, review legal and other requirements, and conduct operational controls, education and training, internal audits, and management reviews, promoting comprehensive environmental conservation activities. In addition, the CSR Management Committee, chaired by the Representative Director and President, and the Environment Committee, chaired by the Executive Vice President, each hold a meeting twice a year to formulate policies for preventing environmental pollution and to report on and deliberate the progress of our initiatives, in order to ensure continuous improvement.

Strategy

To achieve “what Murata wants to be,” we discuss risks and opportunities related to preventing environmental pollution and identify the issues to be addressed based on progressive international standards and trends in industrial organizations.

Reducing VOC emissions

Emissions of volatile organic compounds (VOCs) are said to be one of the causes of air pollution. Murata has endorsed the initiatives of four electrical and electronics industry organizations, including JEITA, and has been voluntarily working to reduce VOC emissions since 2000. This has been achieved through measures such as introducing regenerative thermal oxidizers (RTOs) at business sites with high VOC emissions and implementing material substitutions.
In recent years, there has been a global trend toward stricter VOC regulations. At Murata, the amount of VOCs used is increasing in line with production growth. Therefore, starting in fiscal 2022, we expanded the range of VOCs targeted for reduction and launched additional measures to further reduce emissions.
In general, VOCs are abated by burning the emissions. However, this method generates CO2 deriving from the fuel and VOCs, leading to a climate change risk. Therefore, moving forward, we will not only maintain combustion treatments but also reduce the amount of VOCs used in our manufacturing processes, thereby contributing to a society that balances air pollution prevention with climate change mitigation.

Prevention of environmental incidents

In the event of an environmental incident, the released chemicals can contaminate the air, water, and/or soil and affect the local residents and ecosystem. Therefore, since the 1990s, Murata has worked to prevent environmental incidents and aimed to achieve community-friendly manufacturing. Contamination risks still remain in our business activities, and we will continue our efforts to prevent environmental incidents.

In addition to the challenges outlined, we will continue to advance our environmental contamination prevention efforts, including preventing soil and groundwater contamination by per- and polyfluoroalkyl substances (PFAS) to achieve community-friendly manufacturing.

Targets

FY 2025 targets
  • Number of incidents involving release of effluent to outside the premises: 0
FY 2030 targets
  • Number of incidents involving release of effluent to outside the premises: 0
  • Amount of VOC emissions: 30% reduction vs. fiscal 2021

Initiatives

Reducing VOC emissions

Since 2000, Murata has been voluntarily working to reduce emissions of 20 specific VOCs by introducing regenerative thermal oxidizers (RTOs) and by implementing material substitutions.
To achieve further reduction in VOC emissions, we will expand the types of these VOC targets and continue to reduce the amount of VOCs used in the manufacturing process as well as the amount of VOCs generated during conventional treatment, thereby contributing to the prevention of air pollution and the creation of a decarbonized society.

VOC emission targets and results

The amount of VOC emissions was 1,544t in fiscal 2024. We reached the goal of reducing emissions compared to the figure in fiscal 2021, which was our 2022-2024 medium-term target.

Reduction of environmental incidents

Murata endeavors to reduce risks in order to keep effluent levels below regulatory limits. By analyzing past events with potential for regulatory limit overruns, we undertake efforts that specifically target high-risk factors. For example, we have revised our risk methodologies to ensure rigorous assessments and introduced our own standards to prevent leaks and releases of chemicals while they are stored and transferred.

Results
Number of incidents involving release of effluent to outside the premises 2
Of which, number of cases resulting in administrative penalties 0

During fiscal 2024, two cases occurred where a liquid chemical leak exceeded regulatory limits. In these cases, small amounts of vehicle oil and wash water from equipment cleaning for disposal leaked, exceeding the regulatory limit at the boundary of our property. Neither incident had a significant environmental impact on the surrounding community. Following our report to the authorities, no administrative enforcement actions, such as suspension of operations, fines, or cleanup orders, were imposed.

Voluntary rules for prevention of environmental incidents
  • Prohibition of underground storage tanks
    In principle, storage tanks for new and waste fuels, organic solvents, and acids and alkalis, in addition to raw water tanks for wastewater treatment, will be located above ground. If it is unavoidable that a tank must be positioned underground, a double-walled tank must be used.
  • Permeation barrier coatings
    Locations in which fuels, as well as new and waste organic solvents, and acids and alkalis are handled will be provided with beds treated with a permeation barrier coating or made of stainless steel.
  • Prohibition of underground piping
    Pipes for transporting fuels as well as new and waste organic solvents, acids and alkalis, and waste liquids from industrial processes, will be located above ground.
  • Emergency containment structures
    Operational areas in which new liquids are received from tanker trucks, etc. or waste liquids are discharged will be provided with a structure that allows immediate containment of any leakage outside the area if any environmental incident occurs.
  • Setting environmental incident levels
    At Murata, we set three levels for environmental incidents and regard everything from exceeding the legally regulated values within our property boundaries to leaks of chemical substances within buildings as an environmental incident. We strive to prevent major environmental incidents from occurring by identifying even the smallest leaks of chemical substances within buildings, analyzing the causes, and taking corrective actions.
  • Measuring the environmental impact emitted from worksites and setting voluntary reference values
    We conduct periodic monitoring with respect to regulations on emissions from worksites under environment related laws. In addition, we voluntarily set reference values which are more stringent than the legally regulated values. We analyze the causes and take corrective action when those reference values are exceeded, and we build a mechanism that does not exceed the legally regulated values.

Soil and groundwater contamination surveys and decontamination

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 since the 1990s.
Specifically, depending on the properties of the soil, the concentration of contamination, and the location of the contaminating source, we apply the in-situ bio method, the in-situ iron powder method, the in-situ oxidation and decomposition method, or other decontamination methods using state-of-the-art technologies to decontaminate the area according to the source of contamination. 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.

Communications with local residents about environmental risk

In addition to aiming to reduce the environmental load of our business activities, Murata works to establish mutual trust with local communities.

During fiscal 2024, the Murata Group’s plants received 10 complaints regarding noise and other matters, 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 our operating sites, so that they can better understand our active environmental efforts.
