Improvement of Recycling Rate

The Group takes a proactive approach to reducing and recycling waste. In FY 2024, the combined total amount of industrial and general waste was 4,999 tons, representing an increase of 2.6% year-on-year. Although the recycling rate was slightly lower than the previous fiscal year, it remained high at 97.9%.
Going forward, we will strengthen initiatives at all business sites for reducing environmental impact and aim for further improvements.

Management of Chemical Substances in Products

The Group investigates the substances contained in raw materials, parts, and other materials. By also working with our customers to gain an understanding of the actual content of such substances and to establish permissible levels, we continue to focus on reducing their use. We also distribute our Green Procurement Guidelines to our main suppliers. These guidelines specify laws and regulations applicable to hazardous chemical substances, the names of those substances, standard values, and so on. We encourage suppliers to understand the importance of controlling chemical substances and to cooperate in reducing their use.

Reducing the Use of Chemical Substances Subject to the PRTR Law

The Group surveys emissions of chemical substances specified by the Chemical Substance Removal Management Promotion Law (PRTR Law) and continuously works to reduce such substances in our production processes and switch to less hazardous substances. In FY 2024, seven business sites at four companies were subject to reporting related to the Law. The Group has adopted PRTR control as a management indicator under the EcoFactory Certification System, and is reducing the use of strictly controlled substances also at plants that are not required to report under this system.

Conservation of Water Resources

To protect our water resources, the Group is engaged in a global effort to reduce our total water use and water use intensity. At our business sites in Japan, we have adopted voluntary management values for each business site according to the management indicators identified in the EcoFactory Certification System and are taking steps to reduce our water use. In FY 2017, we began measuring water use at our business sites overseas and have adopted measures to reduce it.
