Stance and Target

Why is “Effluents and Waste” a critical issue to be addressed?
Explanation of the reason and background

We believe that minimizing the impact of our business activities in Japan and overseas on the environment will lead to sustainable operations. Accordingly, we believe that it is important for effluents and waste to be minimized as much as possible in a form with a low environmental impact.

Vision (attainment goal) / target

Mid-term targets are set for water use in Japan and overseas.
Based on these targets, and after confirming water risks and the status of wastewater, we will improve recycled water use and ultimately aim for a closed system.
We will work to achieve a reduction of 1% in waste materials per unit of waste, and aim for the attainment and maintenance of 100% recycling*1. We will then aim to achieve total zero-emissions*2 at all our production bases.
Specially managed industrial wastes such as PCB, asbestos, chlorofluorocarbons, and mercury, etc., will be appropriately processed in accordance with relevant laws and regulations.
  • 1 100% recycling: Achieve zero final disposal (= direct landfilled amount + incineration disposal amount resulting in ineffective use)
  • 2 Total zero-emissions: Make the direct landfilled amount zero.

Measures for vision achievement

  • We will introduce water recycling facilities, increase recycled water use, and reduce the volume of water discharge.
  • Even in the case of business locations that are legally entitled to have waste disposed of in landfill sites, we will look for and select industrial waste disposal contractors that do not conduct landfilling, and contract with them to undertake recycling processing.
  • The processing of PCB-containing devices will be conducted within the deadline specified by law.

Review of FY 2020 Activities

At overseas production bases in areas with high water risks (Thailand and India), closed systems have been introduced at the time of plant construction, and there is minimal water uptake and no water discharge.
Effluent volume was 6,317,000 m3 (down 8.9% from the previous year). Domestic effluent volume was reduced by 11.2% compared to the previous year due to measures against leakage.
On the other hand, overseas effluent volume decreased by 11.2% compared to the previous year.

Amount of waste material generated at Group companies in Japan and overseas

The amount of waste material generated at all Group production bases in Japan and overseas during fiscal year 2020 increased by 4.6% year-on-year to 42,445 tons.
We achieved zero emissions at the end of fiscal year 2017 at our four overseas production bases including North America, one of which in North America had been conducting landfilling before. We are maintaining zero emissions in fiscal year 2018 as well.
We expanded the scope of calculation in FY 2019, resulting in 88 tons (0.20%) of landfill. In Fiscal 2020, 101 tons (0.24%) were also landfilled. We will continue to work to achieve complete zero emissions.

PCB waste storage and management

Used PCB-containing devices are properly stored and processed according to relevant laws and regulations. During fiscal year 2020, 5.0 tons of PCB-containing devices were processed.
This includes the processing of stabilizers registered and stored since FY2016.
Partial processing was implemented in fiscal year 2020.
Additionally, we will proceed with implementing proper processing of PCB-containing devices in use.

Introduction of Initiatives

At the Onomichi Plant, we have improved and strengthened water filtration capabilities, worked to stabilize water quality, and succeeded in significantly improving the period of possible repeated use.

Amount of waste material generated at production bases in Japan

The amount of waste materials generated in fiscal year 2020 totaled 14,587 tons, representing a 2.9% decrease year-on-year; the unit base of the generated amount of waste materials (per net sales) improved by 5.8% compared to the previous year.
The processing flow for waste materials at production bases in Japan during fiscal year 2020 was as follows.
1) Excluding general industrial waste
2) Consumer paper manufacturing waste, tree planting material, various consumer waste
In order to prevent improper disposal such as illegal dumping, local audits of all our processing contractors are conducted every year. In fiscal 2020, although under COVID-19, we conducted 48 audits in Japan, including Group companies, and 39 audits at overseas factories to confirm that waste was properly disposed of.

Issues and Future
Improvement Measures

  • Selection of overseas production bases of industrial waste disposal contractors that don’t conduct landfilling
  • Development of low-water-use facilities, and review of and investment in closed systems
  • Formulation of disposal plans for devices that are currently in use which contain low concentrations of PCB
  • Consider increasing the effective recycling value by increasing the ratio of valuables from industrial waste
