| Electricity consumption | 3,421,752kWh/year |
|---|---|
| Fuel consumption | 163kl/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".
| Total waste released | 45t/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).
