Management of Waste and Other Emissions

The Nabtesco Group is fostering the activities to reduce landfill waste to zero based on the approach of 3Rs (reduce, reuse, recycle)—the basic practice for establishing a resource-circulating society—, to reduce waste generated by our business activities.

The Nabtesco Group implements thoroughgoing waste management, so waste containing hazardous substances is not emitted.

By reusing components and reducing the production of new ones, Nabtesco is working to minimize the use of resources.

We have been fostering the MRO (maintenance, repair, and overhaul) business to optimized the use of resources and expand sales in the service field.

The Nabtesco Group is working to identify, reduce the use, and prevent the leakage of substances that impact the environment as a result of its business operations. For the plants that are planned to be rebuilt or refurbished, we conduct surveys as required by the related laws and regulations and when pollution is detected, we report it to the local government and conduct necessary purification measures.

In FY2022, as a result of conducting a soil contamination investigation following the start of the first phase of reconstruction work at the Tarui Plant in Gifu, which manufactures hydraulic equipment, lead was detected in an amount exceeding the regulatory standard in some part of the surface soil. In response, we conducted an additional investigation and confirmed that the detection of lead in an excessive amount was limited to the soil surface and the lead did not have any impact on underground water. We reported the survey results to Gifu Prefecture and removed the contaminated soil and implemented other necessary measures in line with the related laws and regulations, thereby preventing the incident from causing any impact to the external environment.

In FY2023, we completed implementation of the soil contamination measures and submitted a completion report, which was accepted by Gifu Prefecture.
