Waste management

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

We have set targets for each of our worksites and each of our departments, and we are working to reduce our waste volume based on the fiscal 2019 to fiscal 2021 mid-term targets.*1 In particular, we are promoting activities to recycle resources to tackle the plastic problem that has arisen in recent times.

We are also implementing countermeasures to respond to natural disasters, for example heavy snows or earthquakes.

Fiscal 2016 to fiscal 2018 mid-term target performance report

Even though we conducted reduction measures such as rationalizing our use of solvents, we were unable to achieve our fiscal 2016 to fiscal 2018 mid-term targets (a 3% improvement in average waste volume from fiscal 2016 to 2018 in terms of real output [compared to fiscal 2011 to fiscal 2015 average waste volume]), falling short by 29%.*2 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.

Based on these results, we are considering 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, there is a risk that 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 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.

Initiatives to recycle waste plastic

In recent years, there has been a growing need for initiatives to recycle plastic in response to restrictions on the import of waste in China and other Asian countries as well as environmental problems such as ocean pollution. Especially in Japan, the amount of waste that cannot be recycled and goes to landfills has increased rapidly due to China’s waste import restrictions. Given this situation, Murata regularly exchanges information with materials manufacturers and considers recycling methods that can produce higher quality raw materials than at present, in order to maintain “zero emissions.”
