Activities to Reduce Landfill Waste

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.

Waste Reduction Targets and Results

From FY 2021 to 2022, we achieved the Zero Emissions target of 0%. We will continue to promote 3Rs in FY2022 in order to maintain the Zero Emissions rate of 0%.

*Here “zero” means 0.05% or lower

Target for waste reduction Zero emissions : (Group target) 0% Zero emissions rate of (percentage of landfill waste vs. total emissions)

Measures to Reduce Hazardous Waste

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

Measures to Reduce Use of Raw Materials

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.

Prevention and Reduction of Pollution: Basic Approach

Concept of Prevention and Reduction of Pollution

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.

Pollution Prevention and Reduction Targets and Results

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. Going forward, we will conduct a soil contamination investigation for each of the construction areas, report the results promptly, and take post-investigation measures as necessary.
