Energy data Electricity consumption: 59,801,520 kWh/year Fuel consumption: 3,053 kl/year

*The fuel consumption values have been obtained by converting the consumptions of heavy oil, kerosene and fuel gas into the equivalent consumption of petroleum. For this purpose, the conversion coefficient for plants in Japan and overseas is the one mentioned in the regular report per "Law Concerning the Rational Use of Energy in Japan".

Waste volume data Total waste released: 1,233 t/year Annual mean recycling ratio: 100%

*"Recycling ratio" refers to a ratio of waste (including salable waste) sold or recycled to the total amount released (other than a waste that appears not to be coped with by the efforts of Murata).

Water quality data The management level is strictly enough to meet the target level.

*N.D. : not greater than minimum limit of determination (Not Detected) *The items lacking a target level are those being subjected to voluntary control. *Target levels are taken from the strictest values stipulated by laws, Okayama Prefecture regulations and agreements with Setouchi city. *Water quality data are the values measured at the final discharge point.

Air quality data The management level is strictly enough to meet the target level.
