Waste Management

Murata’s waste management processes are based on "Compliance," "Control of the production of waste," and "Zero emissions" as fundamental principles.

Based on our 6th Environmental Action Plan, which started in fiscal 2016, we are presently working to reduce our volume of waste products. We are also implementing countermeasures to respond to natural disasters, for example heavy snows or earthquakes.

Status of Progress of 6th Environmental Action Plan

While we implemented measures to reduce our volume of waste production, for example by streamlining our use of solvents, we ran 20% over our target, thereby failing to realize our goal. The cause of this was a rapid increase in our manufacturing volume of product types, generating a high volume of waste per unit of production as a result of the expansion of our business.

At present, we are reviewing the introduction of a wastewater treatment facility that would allow us to treat 15% of our total volume of waste liquid in-house. The facility is scheduled for completion during fiscal 2019.


Measures to Prepare for Disasters

Murata contracts waste treatment contractors to process and recycle the waste products generated by our production activities. In the unlikely event that one of our waste treatment contractors was to suffer damage as the result of a natural disaster, we would be unable to discharge our waste products, and would be forced to suspend our production activities. In order to avoid this risk, we have secured multiple treatment routes to ensure that our production activities are unaffected.

Trends in volume of waste (By type)

*Dangerous waste: Hazardous waste and specially managed industrial waste


Trends in volume of waste production (By method of disposal)

*In Japan, we have maintained a zero landfill volume since 2003. However, this figure does not include waste that must be sent to landfill as the appropriate method of treatment.
