We strive to reduce environmental effect on biodiversity while coexisting with nature, and we use the 3Rs (reduce, reuse, recycle) to reduce waste and make effective use of water resources.
The amount of waste generated in fiscal 2016 by the entire group increased to 20,700 tons from 20,200 tons in fiscal 2015. This increase was caused by an increase in production volume and other factors (see G1).
The waste (including valuables) mainly consists of waste plastic, sludge, and paper scraps (see G2).
The final amount of waste disposed of inside Japan decreased to 6 tons from 18 tons in fiscal 2015. The waste recycling rate, which we aim to improve in the medium term, was 99.9%, which was increased from 99.8% (see G3).
The total amount of waste disposed of outside Japan was 1,700 tons, the same level as in fiscal 2015 (see G4).
Improvement in waste generation per unit of production, which we aim to achieve as a medium-term environmental goal, was 7.4% in fiscal 2016 (see G5). The final amount of waste disposed of per unit of production was improved by 36.2% in fiscal 2016 alone (see G6).
We will continue working to reduce waste volumes, boost in-house recycling rates, and recycle waste into resources at our overseas sites.
Definition of waste: general waste, industrial waste, and items having resale value.
The water usage of the entire group in fiscal 2016 increased to 4,546,000 m3 from 4,332,000 m3 in fiscal 2015. Specifically, the sites inside Japan increased their usage to 1,698,000 m3 from 1,662,000 m3 in fiscal 2015 and the sites outside Japan, to 2,848,000 m3 from 2,670,000 m3 in fiscal 2015 (see G7).
Improvement in water usage per unit of production, which we aim to achieve as a medium-term environmental goal, was 16.7% in fiscal 2016 (see G8).
The amount of recycled water was 492,000 m3.
