Plant initiatives

We use resources and energy effectively and promote recycling to reduce CO2 emissions and industrial waste.

Purchase of CO2-free electricity

Our Head Office/Yutaka Plant and Mie Plant have started purchasing CO2-free electricity from April 1, 2025.
By purchasing electricity generated by local solar and hydroelectric power plants, we can contribute to local production and consumption as well as reducing CO2 emissions.
Currently, the two locations purchase a total of 6,187,800 kWh per year, but we plan to gradually increase the amount of electricity we purchase in the future.

Purchase of CO2-free electricity

Use of Natural Energy

Solar power generation systems have been installed on the roofs of the parking lot and bicycle parking lot.
The electricity generated from this system is supplied to the plant.
Electric vehicles have also been introduced, which will be used as emergency power sources and to raise environmental awareness.

Use of Natural Energy
Overview of Solar Power Generation Facilities
Power Generation Utilization Full self-consumption type
Form of Installation PPA Agreement※ 331Kw
Annual power generation about 383,595kwh

※The facility owner provides the space, and the management company installs the equipment and supplies the electricity generated.

Promoting Recycling

We reuse effluent and waste oil from the factories, collect and recycle leftover wood chips, and recycle heat generated during production process.

Reducing Environmental Impact and Improving Efficiency by Switching from Submersion Pressure Testing to Air Leak Testing

In the product airtightness inspection process, we are gradually switching from the conventional submersion pressure testing method to air leak testing.
This improvement has allowed us to reduce the amount of water used during inspections, thereby lowering our environmental impact and enhancing operational efficiency.

Examples of Initiatives in the Manufacturing Area

■ Main Benefits of the Switch

Reduction in Water Resource Usage:
The water tank and water treatment processes previously required are no longer necessary.
Labor and Time Savings:
Simplifying the inspection process has improved operational efficiency.
Improved Inspection Accuracy:
Detecting pressure changes with sensors enables the identification of even minute leaks.

The deployment of air leak testing is one of our initiatives to achieve eco-friendly manufacturing while maintaining product quality.
Going forward, we will continue to promote improvement activities from both technological.
