Resource Recycling and Waste Reduction

Locations covered: Tokyo Seimitsu Co., Ltd. Hachioji Plant, Hanno Plant (construction completed in July 2023), and Tsuchiura Plant. For the Battery Testing Center Fukushima Site [former Furudono Plant] (business transferred in October 2023), only reduction of resource (paper) use was used in calculations.

We manage the specially controlled industrial wastes specified in the “Act on Waste Management and Public Cleaning” as hazardous wastes.

In fiscal 2025, we generated 59,225 kg of hazardous wastes and recycled all of them (recycling rate: 100%). To reduce the use of mercury lamps classified as hazardous waste, we are switching to LED lights.

We have also completed the disposal of polychlorinated biphenyl (PCB) wastes contained in transformers, capacitors, etc. in accordance with the “Act on Special Measures concerning Promotion of Proper Treatment of PCB Wastes.

In order to reduce wastes, we are implementing various initiatives, such as replacing cardboard boxes for packaging delivered parts with reusable plastic boxes and having wooden pallets picked up by shipping companies. Each plant has targets for waste reduction and reuse of wastes as resources. We are working to increase the recycling rate, with the Hachioji Plant recycling all its wastes by various means including thermal recycling and the Tsuchiura Plant switching to a vendor capable of treating liquid wastes for recycling.

Also, when emitting industrial waste, we issue an industrial waste management manifest based on the Act on Waste Management and Public Cleaning to monitor and manage whether the waste is treated appropriately.

The newly completed Hanno Plant is counted as one of the Company plants.

In order to reduce our use of paper, we are creating an environment in which work can be performed during every process within the company using electronic data. We have replaced documents such as purchase orders and drawings with electronic data through the electronic transaction system (ACCRETECH Web-EDI System), which was launched into operation in December 2023. Going forward, we will further promote a paperless environment by expanding the application areas of our electronic transaction system and entrenching the system across the entire supply chain. While the amount of paper we purchased in fiscal 2025 increased by approximately 373 kg compared to the previous fiscal year, we saw a year-over-year improvement of 9.3% in terms of one of our reduction indicators - production volume intensity.
