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 FY2017 by the entire group increased to 22,600 tons from 20,700 tons in FY2016. This was caused by an increase in production volume and other factors (see G1).
The waste (including valuables) mainly consists of waste plastic, sludge, and waste oil (see G2).
The final amount of waste disposed in Japan decreased to 5 tons from 6 tons in FY2016. The waste recycling rate, which we aim to improve in the medium term, was 99.9% (see G3).
The total amount of waste disposed outside Japan increased from 1,700 tons in FY2016 to 1,900 tons in FY2017 (see G4).
Improvement in waste generation per unit of production, which we aim to achieve as a medium-term environmental target was 10.2% in FY2016 and FY2017 on average (see G5). The final amount of waste disposed per unit of production was improved by 35.9% in FY2016 and FY2017 on average (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.
99.9% of the waste generated in the course of our business activities is recycled and reused as resources in society. However, we are also promoting efforts to reuse waste for the business activities of the Taiyo Yuden Group.
For solvent A, which is the most frequently used solvent in our business activities, 16% of the amount used is recycled waste solvent. In addition, for reels that are used for packaging electronic parts, strict quality checks are performed and 16% of all the reels are recycled reels.
The water usage of the entire group increased from 4,546,000 m3 in FY2016 to 4,581,000 m3 in FY2017. Specifically, the sites in Japan increased their usage to 1,717,000 m3 from 1,698,000 m3 in FY2016, while the sites outside Japan increased to 2,864,000 m3 from 2,848,000 m3 in FY2016 (see G7).
Improvement in water usage per unit of production, which we aim to achieve as a medium-term environmental target, was 24.1% in FY2016 and FY2017 on average (see G8).
The amount of recycled water was 514,000 m3.
