Waste Management

Basic approach

Our group is a manufacturing company, and the generation of waste is unavoidable in our production activities. Waste oil, waste plastic, and waste water account for approximately 80% of domestic waste discharged externally, and we are focusing on these areas and promoting measures. Specifically, we aim to minimize the amount of waste discharged externally by developing production processes that generate less waste, examining waste treatment methods, promoting resource circulation such as reuse and recycling, and sharing waste reduction know-how globally. We are working on

The amount of domestic waste discharged externally was 13,466 tons (3.5% reduction compared to FY2021).

We will continue to work to reduce the amount of waste generated by promoting on-site recycling at our manufacturing bases, controlling the amount of plastics and waste oil generated, and considering wastewater treatment methods. Domestic) Aiming for a 19% reduction compared to FY2020.

The final disposal rate for the total amount of waste generated in Japan is 0.03%, and all of our business sites have achieved zero emissions.
