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.
In particular, we believe it is crucial to properly handle hazardous waste without resorting to transportation or importation to foreign countries.
In particular, we believe it is crucial to properly handle hazardous waste without resorting to transportation or importation to foreign countries.
Vision (attainment goal) / target
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.
Furthermore, we will maintain zero emissions of hazardous waste by implementing proper management practices. To this end, we will handle special industrial waste, including PCBs, asbestos, refrigerants, and mercury, in accordance with legal 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
- 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 2023 Activities
Waste volume of domestic and overseas groups
The total amount of waste (disposed of) by the entire domestic and international group in fiscal year 2023 reached 54,632 tons, an increase of 11.8% from the previous year. This increase is attributed to the inclusion of Y-TWS (expanded boundary) resulting in higher production volume, despite 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 fiscal year 2021, 857 tons (1.63%) of waste was landfilled, followed by 942 tons (1.93%) in fiscal year 2022.
In FY2023, there was an increase in production, which resulted in an increase to 1.959 tons (3.59%).
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. 17.2 tons of PCB-containing equipment was disposed of in FY2023.
In 2024, we will continue to properly dispose of PCB-containing equipment in use.
In 2024, 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
In fiscal year 2023, waste generation amounted to 13,679 tons, representing a 0.26% increase from the previous year. The waste generation rate per unit of sales (waste generation intensity) also increased by 3.3% year-on-year. This increase is attributed to a decline in production volume. Conversely, the significant rise in waste generation intensity is primarily due to a 16% increase in waste disposal costs.

The processing flow for waste materials at production bases in Japan during fiscal year 2023 was as follows.

1) Excluding general industrial waste
2) Consumer paper manufacturing waste, tree planting material, various consumer 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 year 2023, a total of 94 audits were conducted within domestic group companies, while 121 audits were carried out at overseas factories, confirming the proper handling of waste in all locations.
Future challenges
- Selection of overseas production bases of industrial waste disposal contractors that don’t conduct landfilling
- Implementation of the disposal plan for equipment containing low-concentration PCBs within the specified timeframe
- Consider increasing the effective recycling value by increasing the ratio of valuables from industrial waste
