*1This was calculated by converting the number of reclaimed wafers produced by the factory to 8-inch wafer equivalent.
*2The sludges produced by us are difficult to estimate because they are processed by a joint facility used by other companies. Hence, this amount was excluded from the amount of discharged industrial waste.
