Reducing Waste & Preserving Water Resources

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.

Results of Reducing Waste

In FY2014, the Group’s overall waste volume increased from 18.5 kilotons in FY2013 to 19.5 kilotons. This increase was due to factors such as an increase of production volume (See G1).
The figures for waste, including items that have resale value, reveal that the largest shares are for plastic refuse, sludge, waste paper, and waste oil (See G2).
Domestic final disposal volumes increased from 0.017 kilotons in FY2013 to 0.029 kilotons. The waste recycling rate of the environmental medium-term target decreased to 99.5% from 99.7% (See G3).
Overseas final disposal volumes decreased from 2.3 kilotons in FY2013 to 1.6 kilotons (See G4).
The waste generation per unit of the environmental medium-term target improved by 27.6% on average for FY2011-14 (See G5). The final disposal volume per unit improved by 42.5% on average for FY2011-14 (See G6).
We will continue working to reduce waste volumes, boost in-house recycling rates, and recycle waste into resources at our overseas sites.

Results of Water Resource Efforts

In FY2014, the Group’s overall water use increased from 3,564 thousand cubic meters in FY2013 to 4,059 thousand cubic meters. This figure includes an increase from 1,234 thousand cubic meters to 1,743 thousand cubic meters at domestic sites, and a decrease from 2,330 thousand cubic meters to 2,316 thousand cubic meters at overseas sites compared with FY2013 (See G7).
Water use per unit of the environmental medium-term target improved by 40.6% on average for FY2011-14 (See G8).
The amount of recycled water was 371 thousand cubic meters.
