Our position and Targets

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 2022 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.
The table below shows the volume of water discharged.
Overseas production increased, but the effluent discharge amounted to 6,298 thousand m3 (down 2.63% from the previous year). Effluent in Japan decreased 2.3% from the previous year, as leakage countermeasures also continued.

Waste volume of domestic and overseas groups

Despite the increase in production volume, the total waste volume (amount processed) for the entire domestic and overseas group in FY2022 was 48,865 tons, a 5.8% reduction from the previous year, as a result of efforts to improve production efficiency and quality.
We have been working to achieve complete zero emissions at all production sites in Japan and overseas through recycling.
In 2020, 677 tons (1.40%) and 857 tons (1.63%) were landfilled in FY2021.
In FY2022, there was an increase in production, which resulted in an increase to 927 tons (1.93%).
We will continue our efforts to achieve complete zero emissions and recycling treatment.

PCB Waste Storage and Management

We properly store and dispose of used PCB-containing equipment in accordance with laws and regulations. 10.5 tons of PCB-containing equipment was disposed of in FY2022.
In 2023, we will continue to properly dispose of PCB-containing equipment in use.
Hazardous Waste Disposal Flow

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 generated in FY2022 was 13,569 tons, down 5.7% from the previous year, and the basic unit of waste generated (per net sales) also improved by 2.8% from the previous year.
This was due to improved yield amid increased production volume. On the other hand, the lower basic unit is due to disposal costs remaining high.
The processing flow for waste materials at production bases in Japan during fiscal year 2022 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 2022, although under COVID-19, we conducted 100 audits in Japan, including Group companies, and 100 audits at overseas factories to confirm that waste was properly disposed of.

Future challenges

  • 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
